Management of International Reserve: a Case Study of China Abstract Don’t waste time! Our writers will create an original "Management International Reserve" essay for you Create order The remarkable foreign reserves in China during the last decade have been boosted forward the world. Particularly in the aftermath of Asian financial crisis, China enable to succeed in avoiding the financial shock and economic meltdown and recovering in short time among others Asian countries mainly owe to huge protective reserves hoarding. Nevertheless, the soaring foreign reserves have triggered a series of debates on Chinas reserves adequacy. This paper explores theoretical interpretations for the demand for foreign reserves on the basis of previous literatures and empirically estimates the determinants of reserves holding. The implication of management reserves holding in China is presented as well. Some proposed suggestions based on the management targets can be found at the end of the paper. Key words: foreign reserves, imports, external debt, Asian financial crisis, management measures 1.0 Introduction In 2006, Chinas foreign reserves have reached more than US$850bn which makes China replace Japan as the largest holder in the world. From the last decade, particular in the aftermath of Asian financial crisis, foreign reserves have been growing fast with the well development economy in China. In 2000, Chinas foreign reserves accounted for 14.33 percent of its GDP which is consistent with the last year. However, from then on, the ratio has been increased continually and was 61.66 percent of GDP by the end of 2007 (see Table 1.0). Figure 1.0 describes the tendency of the foreign reserves to GDP ratio from 1995 to 2007. As can been seen, after the 97-98 Asian financial crisis, the ratios still maintained in a constant level which is roughly 15 percent. However, since 2000, it had been a rapid soar from 15% up to 50% within only five years. This dramatic growth has attracted the eyeballs from all over the world and aroused a series of debates on the issue whether it is a rational behavior of foreign reserves market. Some believes that it is beneficial to Chinas economy due to a number of reserves positive functions while others criticise the huge reserves holding bring out potential risk to financial system and international markets. In fact, increasing reserves holding not only show the Chinese overall economic strength has grown, but have also caused internal and external pressure. Zheng and Yi (2007) analyse the pressure in detail: Internally, government debts are mounting as a result of official operations of sterilization of net capital inflows and inflationary pressure is increasing. Externally, China faces intensified pressure for a rapid appreciation of currency. The huge foreign reserves can cause imbalances in the countrys economy. Regarding such pressures faced by Chinese government, it is necessary to reconsider whether foreign reserves are excessive and what measures it should take to management large reserves hoarding. To address this question, we have to explore what is the cause behind the huge reserves holding in China. As we know, the obvious reason for Chinas fast-expanding reserves holding in recent years is continual surpluses in the current and capital accounts of Chinas balance of payments. Figure 1.1 illustrates Chinas imports and exports volume from 1995 to 2007. The comparison in the histogram reflects an imbalance between imports and exports of China. We can analyse the balance sheet of payment further from the structure of reserves composition. Theoretically, foreign reserves can be divided into creditors rights-based reserves and debt-based reserves. The former is reserve from current accounts, while the latter is from the capital accounts. Foreign reserves of developing countries are mainly composed of debt-based reserve (Wang, 2006). From table 1.1, it can be seen that in 1995 and 1996, Chinas foreign reserves were mainly from the capital account which resulted from the increase in foreign direct investment (FDI). Since 1997, the creditors rights segment of Chinas foreign reserves is the mainstream. However, during 2003-2004, there is a dramatically rebound in debt-based reserves from US$52bn up to US$111bn. This was consistent with the growth rate of reserves holding. More broadly, it is remarkable that the expectation for renminbi appreciation so high that resulting in a large amount of speculative capital (see Table 2) has inpoured. Wang, (2006) points out that Central Bank in China has implemented a compulsory foreign exchange settlement policy to maintain the renminbi exchange rate. The principle policy is to enhance foreign reserves in support of exchange rate policy which is an important factor behind expanding foreign reserves. However, this is only one aspect of the huge reserves holding in China. In this paper, we are aiming to explore various aspects hidden in huge foreign reserves holding of China and discuss what measures should be implemented to manage such large foreign reserves and have a better utility of them. 2.0 Literature Review 2.1 Introduction Since 1960, a series of studies had been published to explore the issue of international reserve adequacy and its management strategy. Among them, Clower and Lipsey, (1968), Grubel have presented explicit reviews of the previous literatures. They have contributed substantially to the stock of knowledge in this field. However, these studies mainly focused on the last 20 years before which may not suitable for the researches today. Therefore, a more comprehensive and renewal review of the literature on the issue of international reserve should be displayed. That is the main purpose of what we are going on here. In the following sections, we will present review both on theoretical and empirical literatures up to date in order to show how its theories and methodologies develop. 2.2 Demand for Reserves: Early Views in 1960s to 1970s Apart from the motivations of international reserves holding, the optimal demand for foreign reserve is the mainly focus of economists. Machlup (1966) concludes that There is no sense in which it can be said that the world total of monetary reserves is inadequate. Indeed, since the 1960s, the economists have been attempting to find out the actual demand for the international reserve. And it seems no one can give an affirmative answer on reserve adequacy. In their studies, all econometric estimation of the demand for international reserves are based on the fundamental task that the econometrician is to measure determinants of the demand. Clower and Lipsey, (1968) give a pessimistic view that we can not really hope to judge the overall adequacy of reserves in the present situation in which destabilizing speculation is encouraged. The earlier views of the reserves holding in uncertainty are passive by the reason that in practice all determinants of the foreign reserves are unpredictable, no matter what factors they are faced, such as stability of trade in goods and services, long-term capital flows, or foreign and domes tic price and investment. Some economists believe the probability distributions of future values of these variables tend to have smaller variances. It may be true that reserve carry little weight relative to economic environment in the earlier period. Furthermore, in 1971, the study from Flanders suggests that the determination of foreign reserve holdings may be a non-economic phenomenon due to policymakers who just maintain the reserves holding above some minimum critical levels. As can been seen, the mainstream of the earlier period studies is in a passive atmosphere. After going through the literatures in early 1960s and 1970s, the studies of the issue on international reserve are apparently not enough, particular in the analysis of reserve adequacy. Thus, for the purpose of analysis, the principle task for researchers is to define measurement of reserve adequacy. All authors recognise that not all forms of international reserves can be convertible with equal speed and capital certainty, thus, it is hard to define a standard measurement to estimate the adequacy in all countries. However, in practice, it has been necessary to define reserve as assets which are acceptable at all times to foreign economic units (Heller, 1966, p296) and measurable. Qualifying under these and similar definitions are national holding of gold, convertible foreign exchange, and unconditional drawing rights with IMF, for which the IMF provides ready and consistent estimates for a large number of countries. These estimates can be seen in the studies of M. Flanders, (1971), Machlup, (1966), Heller, (1966), Kelly, (1970), and P.B Clark, (1971). Moreover, when some authors argue whether these reserve assets should be adjusted for private liabilities towards foreigners, most studies consist with P. B Clarks view that calculations which based on gross and net IMF positions t urn out similar results. The theoretical discussions of the nature of reserves holding in the studies are severe. In any case, the studies at that time indeed give a direction to economists to explore in depth. With respect to the previous literature on the determinants of foreign reserves holding, there were a large number of empirical papers in the 1960s and early 1970s, such as Kenen and Yudin (1965), Kelly, (1970), Flanders, (1971), Herbert, (1971) and Frenkel (1974). These studies on the demand for reserves holding can be divided into three groups according to the methodologies of analysis they employ. They are ratios, regression techniques, and computer simulation. Here, we mainly focus on the ratios indicators and regression methodologies. It can be realized that all studies of reserve adequacy have to deal with the problem that foreign reserves in different specific countries can not be compared, traced through time, unless they are standardised in some way to reflect difference in countries size or economic condition. As we know, the scale variable in the most widely used is imports. Besides imports, two more classes of scale variables used in the studies are domestic money supplies and liquid liabilities, net external balance. These variables reflect countries potential exposure to increase in aggregate demand for goods and services and have a close relation with the reserve demand. Ratios as a tool to measure reserve adequacy is less efficient because the most difficult problem facing the users of ratios is how to interpret past changes and predict future ones in these ratios. Many analysts using ratios show recognition of the issue involved, but they are more likely to use of ratios as the best empirical tool available for the analysis of reserve adequacy in the past and for the prediction of future demand. According to Browns analysis (1964), he believes that demand is satisfied when ratios is constant. In contrast to Machlups study (1966), the efficiency of ratios indicators is suspected in the analysis of the demand for foreign reserves. He shows the difficulties involved in establishing theoretically why any of the ratios he selected should be constant across countries or through time. His statistical analysis demonstrates that all ratios are very different for countries and periods under examination. To sum up, ratios as a tool to measure reserve adequacy is not as efficient as analysts expect. Therefore, more and more researches trend to employ the regression methodologies rather than the ratios indicators. The mainly regression technique for estimating reserves demand functions is to apply time series and cross-section which also can be seen in Table 2.0. Courchene and Youssef, (1967) used seasonal time series to estimate night countries reserves holdings as a function of their imports, money supply levels, and long-term interest rates. The main innovation of their study was to move in the promising direction of estimation demand functions for individual countries from time series rather than for a group of countries from a cross-section sample. Another economist Thorn (1967) used the 14 countries sample of specific countries and considers the 1960 reserves to import ratio for each country as it reserve target and test for the years 1954,1957, 1962, and 1964, the equation are as followed: (1) where R is actual reserves, I denotes as imports, and is the ratio of reserves to imports of countries i, where i=114. The shortcoming of Thorns model is that the coefficients took on the values zero (a0) and one (a1 and a2) merely reflects the fact that during the period under observation both reserves and imports grew roughly at the same rate. Kenen and Yudin, (1967) has pointed out the weakness and improve by a rewriting form: (2) The uses of variables and regression technique are largely identical but with little differences. Until Kelly published the study in 1970, there is an important innovation in estimating technique. The study combined annual data for the period for 46 countries in on main regression with a dummy variable for each country. Cross sections were also computed. The empirical results are very good which resulting in high correlation coefficients and most regression coefficients with high statistical significance and the right sign. Another innovation in that period is from Clark, 1970 who uses an autoregressive equation in the tradition of Kenen-Yudin to derive a proxy for individual countries payment instability. It establishes that the demand for reserves and the speed of adjustment are an increasing function of payment instability. This may be worth pursuing further to find out the more relations in the estimation of demand functions from long run time series. Considering the empirical re searches, it suggest that deriving reserve demand functions for individual countries from time series is easier than estimating a more generally valid function from a cross section of countries. That is because larger numbers of structural characteristics of economies which determine the demand for reserves of individual countries can not be measured adequately and incorporated in cross- section studies. Thus, if estimating one single country reserve adequacy, it is reasonable to assume there is only small change through time so that the observed statistical relationships among variables are stable and constant and reflect rational economic behavior. 2.3 The recent empirical literatures in 1980s and 2000s After 1970s, the literatures focused on using international reserves as part of the management measures of exchange rate regime (Frenkel and Jovanovic, 1981). They develop a model also known as the buffer stock model or inventory model which concentrates on the demand side. It based on the idea that optimal foreign reserves are determined by the balance between macroeconomic adjustment costs and opportunity costs of holding foreign reserves. He believes that ooptimal foreign reserve depends on the variability of international transactions and reserves are a buffer stock to accommodate fluctuations in external transactions. Demand for reserves is a stochastic process driven by payments and receipts. Expected reserve holdings are a positive function of volatility and a negative function of the opportunity costs of maintaining reserves Frenkel-Jovanovic Model is shown as below: (3) where Rt is reserve, W (t) is the standard Wiener process1 with mean zero and variance t. dt is the change in reserves in a small time interval, which is normally distributed and the distribution of reserves can be defined as: (4) where R* is the optimal initial level of reserves, ÃŽÂ ¼ is deterministic part of the instantaneous change in reserves and à Ã†â€™ is the standard deviation of the Wiener increment in the reserves. A further econometric formulation can be seen as followed: (5) where b0 is fixed cost, b1 is adjustment cost, b2 is opportunity cost. And the empirical evidence is very close to their theoretic prediction which supports the justification of the model. The model predicts that average reserves depend negatively on adjustment costs, the opportunity cost of reserves, and exchange rate flexibility; and positively on GDP and on reserve volatility, driven frequently by the underlying volatility of international trade. Overall these predictions are supported by the literature of the 1980s. But, it failed to explain the recent reserve hoarding in emerging markets. Since the economic environment has been taken place in last decade, more recent studies are provided by Ben-Bassat and Gottlieb (1992), Bordo and Eichengreen (1998), Aizeman and Marion (2004) to renew the development of reserves management. These papers typically study a much smaller number of countries and a much narrower set of explanatory variables than are considered in this paper. For instance, the Ben-Bassat and Gottlieb, (1992) argue that a central bank determines the optimal reserve level R* by minimizing the following expected cost function: (6) where à Ã¢â€š ¬ is the probability of a countrys default due to economic and financial turmoil. The Equation tells that the total cost of holding reserves is the summation of the expected cost of forgone returns on reserves R and the expected output loss C due to the countrys economic or financial crisis. The first condition of the cost function is: (7) Solving the condition, it can be rewritten as: R* = (1-à Ã¢â€š ¬(R*))/ à Ã¢â€š ¬R (R*) + C/r (8) It reflects optimal reserve is a function of the cost of failure, net opportunity cost and the absolute and the marginal default probabilities at given reserve level. They also suggest Central Bank should choose the level of reserves to minimize expected costs of holding them, which are the net costs of loss due to economic crisis and opportunity costs of holding international reserves. Another study of Bordo and Eichengreen (1998) includes only twenty-one countries and considers only country size, trade openness and volatility measures as potential determinants of reserves. It seems a small size of the view and not in a adequately estimation. The updated study from Aizeman and Marion (2004) examine the contribution of reserves and external debt to tax smoothing for the case where future productivity is random, showing the welfare gain associated with hoarding a potentially large stockpile of international reserves. It is noteworthy that sizable precautionary demand for international reserves exists even if agents are risk-neutral: the non-linearity associated with costly taxation and sovereign risk suffice to induce a first order demand for reserves, independent of risk aversion. They also build up models which belong to the broad optimising model family, and are known as the self-insurance models as against the buffer stock model by Frenkel-Jovanovic Model. Furthermore, in 2005, Aizenmean and Lee go further in the research to extent Ben-bassat and Gottlied model which implies foreign reserves are output stabilizers that can reduce the probability of an output drop induced by a sudden stop of foreign capital and/or the depth of the output collapse when the sudden stop materializes. The study also has empirical findings that the precautionary demand is the main motivation of hoarding reserve against Mercantilism of reserve accumulation (Dooley et al., 2003). 2.4 Literature reviews on emerging market There is a series of researches arise from the Asians crisis since 1997. The views on the reserves holding in Asian emerging market in the aftermath of crisis are various. Primarily, it is necessary to reconsider the reasonable reserves levels. It is suggested from the crisis lesson that the currency reserves holding level can be an important indicator and predictor of a financial crisis (Fischer, 2001). A better reserve and debt management system may have reduced the possibility of crisis. The conventional indicators of reserve adequacy based on current account instability may be appropriate for some countries, which may be faced with payment vulnerability due to trade related shocks (Bird and Rajan, 2003). However, for other countries such as the emerging market economies(EMCs), which carry a substantial short-term external debt, the ratio of R/M2 are unable to capture the payment shocks. It is necessary to consider the size of reserves and short-term external debt (Greenspan, 1999). The composition of short-term debt has been found as a key indictor of illiquidity in the financial crises such as that of Mexico in 1994-1995, East Asia in 1997-1998, a nd Russia and Brazil in 1998-1999 (Dadush et al., 2000; Hawkins and Klau, 2000). Indicators for assessing foreign reserve adequacy for emerging market are not identical for each country. In the next part, we will specify some indicators in empirical estimation to find out how to assess demand for China foreign reserves. The literature review on the issue of the demand for international reserves leads to a conclusion that the earlier studies in 1960s and 1970s are well developed and several seminal papers gives new direction to the research on international reserve adequacy by showing that econometric estimates of demand functions for reserve on the basis of past experience which can not provide information about optimal reserve supplies in the future. Regarding with the recent research in recent years, the analysis trend of reserve adequacy is more comprehensive and well improved the previous weakness of ratios and regression techniques. The innovation of reserve issues can be seen as a well presentation in the literatures. 3.0 Empirical Specification and Finding 3.1 Introduction In this part, we are going to perform empirical assessment to rethink the management of international reserves by the Chinese monetary authority. We first employ methodologies to illustrate the mainly factors which are behind the large accumulation of international reserves in the last decade. By taking a retest on foreign reserves and other related macroeconomic variables, we attempt to give a comprehensive cognition of the optimal level of hoarding and how to manage such massive foreign reserves in China. 3.2 Data and Methodologies In this paper, we design to employ two methodologies which based on the development theories of foreign reserve adequacy suggested by the economists mentioned in the Part 2. In order to estimate whether the current foreign reserves of China is in a suitable level which adapt to balance of payment and exchange rate regime, the ratios as the most obvious tools of analysis will be demonstrated in the empirical evaluation. We are going to look at three indicators for this assessment based on the prevailing theories of reserves from 1960s to 1970s which are reserves to imports; reserves to M2 and reserves to net external balance. Meanwhile, the assessment period will be focus on the last ten years from 1995 to 2007. That is because during the last decade, China has experienced a tough economic environment in the aftermath of Asian financial crisis and entered a rapid development era, hence, this time series data and ratios may be useful and characteristic to well present the economic feat ures. The original estimated data such as Chinas foreign reserves, import, export and M2 figures are sourced from the Datastream database and some statistics are gathered from the NBSC (2007). The compare and contrast will be given in the result analysis section. As a significant indicator, although it has the weakness, ratios is still an irreplaceable tool to give a general image of the reserves adequacy of one country. The second tool of analysis is to use econometric formula to estimate optimal holding according to the models on reserves adequacy. As can be seen in the literature review, there are a number of well developed models that demonstrate different situations of reserves holding. Considering of advantages and shortcomings among these models and the direction of assessment, we intent to employ two mature models suggested by Frenkel and Jovanovic (1981) and Aizenmean and lee (2005) in the empirically evaluation s of reserve management in China. Frenkel-Jovanovic mode as a buffer stock or inventory model has remarkably successful in explaining foreign reserves holding in the 1980s. It has performed empirically and proceeds to useful outline of optimal reserves. This model hypothesises that the reserves authority will choose an initial level of reserve holding that minimizes its total expected costs which consist of macroeconomic adjustment costs and opportunity costs of holding foreign reserves. In the working paper from Flood and Marion (2002), it points out that the two costs are interrelated due to a higher stock of reserves. The optimal reserve management is to find the cost-minimizing level of reserves to acquire once reserves have reached their lower bound. That is to say, a reasonable level of reserves holding is to optimise the trade-off among the costs produced from the hoarding. Furthermore, Frenkel and Jovanovic (1981) assumed that reserve movements between the occasional re-stockings are generated by an exogenous Wiener process, where the incremental change in reserves in a small time interval is distributed normally. Based on the previous FJ formal modelling formulations (3) and (4) shown in part 2, a new derivation of the optimal reserves holding developed by Frenkel and Jovanovic (1981) can be presented as followed: 2 (9) Where R* is the optimal reserve; C is a fixed cost per adjustment, related to the capacity to adjust expenditures to income; r is the cost of holding reserves per unit of time, representing the cost of forgone earnings. Finally, à Ã†â€™ is standard deviation of the Wiener increment in the reserve time-series process operating between stock adjustments. In the equation (9), optimal reserve holding increase with the volatility of reserves (), and higher volatility equals that reserves hit the lower bound more frequently. Therefore, the money authority prefers to restock a large amount of reserves and tolerate greater opportunity costs so as to incur the adjustment costs less frequently. It can be also seen that a bigger adjustment cost lead to a larger optimal reserve holdings while a higher opportunity cost shrink them. In a word, it reveals optimal reserve holdings to be a positive function of volatility and a negative function of the opportunity costs of maintaining reserves. To be more straightforward, the expression (9) can be transformed into the log form which is a successful estimating equation: 12 (10) For the purpose of empirical test, this estimating equation finally becomes a convenient econometric formulation like below: 3 (11) It is quite straightforward to use the econometric formulation to estimate the variables. Because FJ realise that obtaining a variability measure was free of scale, thus, to make it feasible and simple, they divided the standard deviation by the value of imports and the opportunity cost, r, was approximated by a countrys government bond yield. They also define that the component estimating coefficients b0, b1 and b2 are namely fixed cost, adjustment cost and opportunity cost. In particularly, the constant b0 is interpreted to be country specific and regime specific. In the empirical work from FJ, they estimated the models by using ordinary least squares on various cross-section and panel data sets. They once estimated across 22 developed countries during the 1971 to 1975 period. The result can be seen as below: (12) R2= .97, n=110, S.E= 0.234 Their empirical evidence is closely consistent with their previous theoretical finding since the estimated coefficients of reserve holdings with respect to and r is very close to the predictions of the theoretical model given by equation (10). After explaining the methodology, we attempt to replicate the FJ regression equation in Chinas foreign reserves analysis by using PcGive program. The data sets are in time series which come from Datastream and NBSC as well. It is noticeable that the estimation may not be accurate due to technique issue and scaling issue. But we will try to make the process clear and integral. We now commence our effort to retest this model in Chinas foreign reserves and discuss the findings in detail in the next section. The output of the estimation can be shown in appendix. On the other hand, we will go further to estimate the Chinas foreign reserves via new theoretical model suggested by Aizenman and Marion (2004). Unlike the general framework, there are some limitations of FJ model which lead to under perform in emerging market. The first limitation is using fewer factors as scaling variable for determining reserve adequacy. Crises during the 1990s and beyond have predominantly been crises of the capital account. Reserve adequacy benchmarks accordingly need to be modified to allow more variables influenced on reserves (Bird and Rajan, 2002). The other limitation is that FJ model does not explicitly capture changes in loss aversion. According to the precautionary motive on demand for reserve adequacy, holding reserves may be considered a form of insurance premium, which means that reserves hoarding has the functions to avoid future crises and reduce the probability of an output drop induced by a sudden stop of foreign capital and so on. It can be thoug ht as an approach to stabilise fiscal expenditure in developing countries (Aizenman and Marion, 2004). That is to say, in emerging market, the political factors may have a great impact on reserve holding rather than developed countries. China is the most important developing counties in Asia and we should consider various factors in the management of foreign reserves. Thus, we commence to retest the reserves holding in China on the basis of the extension of theoretical model generalised by Aizeman and Marion (2004). The estimating equation is as followed: (13) where: R is actual holding of reserves minus gold; pop is the total population of specific country; gpc is real GDP per capita; exa is the volatility of real export receipts; imy is the share of imports of good and services in GDP; neer is the volatility of the nominal effective exchange rate. Regarding to the study of Aizenman and Marion, (2003), they point out that the real holdings should increase with the size of international transactions; hence, they expect reserves holding to be positively correlated with the countrys population and standard of living. Moreover, reserves holding should increase with the volatility of international receipts and payments which would make it positively correlate with the volatility of export receipts; and it is also expected to increase with the vulnerability to external shocks which means be positive with import. And finally, since the severe fluctuation of exchange rate will reduce the demand for reserves thus, reserves should be negative with the exchange rate. Aizenman and Marion explain the choice of variables in detail in order to construct a structural model. In the case of China, making the test simply and clear, we intend to apply reduced-form of the model and use a few of significant variables instead of complication. It is remarkable the sample data is during the period from 1998 to 2007. We expect to find out the change of management of reserves holding in the aftermath of Asian financial crisis. The model we estimate involves variations of the following equation: (14) where: Rt is the actual reserves holding; ca is the capital account balance; ed is the net external debt; imy is the ratios of import to GDP; RM2 is the ratios of reserve to M2; neer is the volatility of the nominal exchange rate(standard deviation of exchange rate movement). The estimation output is reported in the appendix. The discussion of the finding will be presented in the next section as well. 3.3 Result Presentation and Analysis 3.3.1 Ratios Indicators The four key ratios indicators will be introduced in this part to outline the structure of foreign reserves in China. Although ratios indicator can not tell the full condition of the reserves holding, they still play an important role on the analysis of reserves level and reflect the significant problems. i. Reserves-to-GDP(R/GDP) The first principle ratio presented here is Reserves to GDP which has mentioned in introduction. Table 1.0 shows the actual data and the R/GDP ratio from 1995 to 2007. In the half end of 1990s, reserves holding in China were in a stable growth level. Consisting with the development of economy, R/GDP has been growing fast, especially after 1998. In 1999, Chinas foreign reserves accounted for 14.5 percent of its GDP. In the next 2 year, until 2000, the ratio seems maintain in the similar level. However, it has been increased again in 2001 and was reach more than 60 percent of GDP by then end of 2007 (see table 1.0), which made China become the largest foreign reserve holder in the world. Obviously, the reserves holding follow the development of economy. ii. Reserve-to-M2(R/M2) Another indicator is R/M2 is considered as a predictor of financial crisis (Kaminsky et al., 1997). A higher level of this ratio will reduce the probability of crisis. Figure 3.0 reflects there is a gradual increase of the ratio after 2000, it shows evidence that china has strengthen the management of reserves holding after Asian financial crisis. The R/M2 can be a useful indicator of the potential impact of capital flight, but, further discussion needs to be supplemented by analysis of other possible sources. iii. Reserves-to-IMPORT(R/IM) and Reserves-to-EXPERNAL DEBT(R/STED) The most common ratio in previous foreign reserves literatures, R/M ratio reflects how sufficient of reserves on the foreign import. But Bird and Rajan, (2003) find out it lacks a linear relationship between the occurrences of deficit and value of imports which may fail to reflect the actual condition. However, we still consider it as a main measurement. It can be seen from table 3.0 that the R/IM ratios are very high in China and Korea and Malaysia are less than 3 before the Crisis. It is remarkable that Korea has boosted the ratio from 2.9 up to 8 after the crisis which implies a great adjustment in trade policy. The last indicator which is considered most relevant for emerging markets (Wijnholds and Kapteyn, 2001) is R/STED. STED is denoted as short-term external debt which debt obligations with an original maturity up to one year. It indicates that countries with low value were most likely to be affected by the financial crisis (Dadush et al., 2000). Table 3.0 summarizes the reserve adequacy indicator: R/IM and R/STED in five main east-Asia countries from 1995 to 2000. They implies that Korea, Malaysia, Hong Kong have all been linked to financial crisis and related to a weak R/STED. China was able to manage a stable exchange rate during the Asian financial crisis due to its comfortable R/STED. 3.3.2. Regression technique On the basis of FJ model formulation, we retest Chinas foreign reserve during the period from 1995 to 2007. In this regression, we apply the traditional determinants of the demand for international reserves such as GDP, IMPORT, and EXTERNAL DEBT. It should be noticed that when scale R by these factors, the right-hand side variables have to do the same procedure. In the table 3.1, it reports the results using the three scaling variables mentioned above. As can be seen from the output, we interpret our result is consistent with those FJ model equation (10) since the estimating coefficients is approximately close to the theoretical prediction. Our approach differs from the primarily because we use others scaling factors. In the estimation, reserve volatility still positively influences reserve holdings. It can be seen that the reserve volatility in benchmark regression (a) of table 3.1 has a closest elasticity of 0.58 without scale factor. Meanwhile, the interest rate has a negative and significant coefficient in all regressions as well. Moreover, the value of R2 in first regression also reflect a The estimating coefficients in other three regressions with scaling variables have the similar values which are around 0.4. It is clear that reserve holding mainly depend on GDP factor since the elasticity of reserve volatility in regression (b) shows the highest value among others. Further, IMPORT has a great impact on reserve holding as well. As the opportunity cost, the coefficients of interest rate have a wide range of value although they are all in negative. In sum, the result of the FJ model in Chinas foreign reserves is receivable although parts of the parameters are not perfect. Although FJ model has a good empirical support in reserves holding under certain assumptions, it is noteworthy that it can only predict for developed countries and fail to explain the recent reserves hoarding in emerging market, especially after the Asian financial crisis. Therefore, in the following section, the regression result of the new model (14) introduced in section 1 will be discussed to find out what factors influence on China reserves holding after crisis. We reconstruct the original model (13) from Aizenman and Marion, (2004) by adding five variables that assume to affect the reserves holding. In order to assess the responsiveness of international reserves, we run a new form regression which relates change in international reserves to current account, net external debt, import ratios, money supply and exchange rate movement. The output of result is reported in table 3.2. By regressing the new form model (14) in PcGive, we find out that the criteria of adjusted R square and DW test both show a perfect goodness of fit of the model. When our adjusted R square is very close to 1 and DW is around 2(see table 3.2), it means our regression line is perfectly fit the data offered. From the test result, it can be concluded that the factors of import ratio (LIMY) and M2 money supply ratio (LRM2) have a higher value of coefficients which imply a positive correlation with reserves holding. Although current account balance (LCA) and outstanding external debt (LED) have small value, it still indicates they are positive with reserves holding. Moreover, it is suggested that the volatility of exchange rate has a negative correlation with foreign reserves. In general, the empirical result above is consistent with the suggestion from Aizenman and Marion, (2003). It can be realised from the result that political factors such as fiscal M2 supply, external debt and import volume play an important role to determine reserves hoarding in China. Like Aizenman and Marion suggestion, hoarding of foreign reserves can be viewed as a precautionary adjustment, reflecting the desire for self-insurance against exposure to future sudden stop of foreign capital inflows or economic crisis loss. From the test, we are aware of that political factors may be the dominate determinants to affect the management of foreign reserve in China rather than opportunity cost and adjustment cost. 4.0 Finding and Suggestion 4.1 Finding and extension From above empirical estimation, we can conclude two important findings in this paper. Firstly, there is a positive effect on the large accumulation of foreign reserves in China according to the ratio indicators. Particular in the Asian financial crisis, China enables to survive in the hazard has to attribute to the huge reserves holding which protected renmingbi from devaluation and stabilise the financial market in Asian. Secondly, from the result of our regressions on optimal reserves models, we can find out the latter model has a better simulation of the reserves holding in China than the former FJ model. It implies that the new variables (short-term external debt, M2 supply, volatility of exchange rate) added in the latter model is more relative to reserves holding China. It also indicates that adjustment of these significant factors needs to be considered carefully in management reserves holding. The key findings give us an opportunity to rethink the management measures in reserves holding in China. When we are proud of the first place of the reserves accumulation, the more important thing is to rethink the potential risk and a more advanced management. A Chinese economist Li (2006) give his view on the reserves adequacy. He believes that Chinas foreign reserves are not excessive and in a suitable level since it needs sufficient reserves to maintain the stability of the yuan and to maintain the confidence of international investors. As can be seen in the Asian financial crisis, the mainly reason that China can survive among other countries should attributes to the massive foreign reserve which prevent yuan from depreciation. He also argues that Chinas foreign reserves have been rewarded by sufficient returns. Nevertheless, Chinas spectacular economic development has presented China with a dilemma. Although foreign reserves could earn credibility and maintain stability of the Chinese currency, the accumulation of huge reserves has created pressure for the yuan to appreciate, and its further appreciation would result in financial losses and instability of the currency. Therefore, the issue whether China foreign reserves are excessive has been explored again. Some analysts suggest it would be reasonable to reduce them until an optimal level is reached. Frankel (2004) has emphasized the opportunity cost of massive foreign reserves and believe that China was presumably paying foreign investors on their inward investment a higher return than it was earning from its investment in foreign reserves. Another argument from Xia (2006) points out that approximately 22 percent of foreign reserves accumulated in 2005 were induced by expectations of the Chinese currencys appreciation, mostly in terms of short-term capital inflows. He maintained that US$700bn in foreign exchange reserves should be sufficient. He believes China foreign reserves are fiercely large in light of the adequate level. To identify China foreign reserve whether is excessive or not, we need to analyse the essential causes hidden in the rapid growth of holding. In terms of our study, it can be explained by a few points. i. Exchange rate maintenance For a long time, China has been blamed for manipulating exchange rates regime to maintain international competitiveness. It intervenes in the foreign exchange market to prevent real appreciation of the yuan. However, from July of 2005, China reformed the exchange rate regime by moving into a managed floating exchange rate regime based on market supply and demand with reference to a basket of currencies. RMB has no longer been pegged to the US dollar. After the reform, the RMB exchange rate has become more flexible. It is noteworthy that since 2005, the expectation for renminbi appreciation has been growing continually and a large amount of speculative capital has swarmed in. Therefore, the Central Bank has adopted a compulsory foreign exchange settlement policy to maintain the relative stability of the renminbi exchange rate, which is an important factor behind expanding foreign exchange reserves. ii. Financial Stability As we know, China did not face financial shock during the 1997-1998 Asian financial crisis due to the strong capital controls. Witnessing the damage inflicted on the financial and corporate sector of its neighbours it took measure to tighten the strict foreign debt management as well. At the end of 1997, its foreign debt was 373 US$ billion. Its capacity to service foreign debt, as measured by the growth of foreign reserves, has kept pace with the growth of foreign liabilities. Consequently, the key debt ratios have been kept well with the generally accepted safety limits. In particular, the foreign reserves at that time are four times larger than short-term foreign debt which protects China from economic meltdown. That is why china favors having sizeable reserves holding because it insists that large foreign reserves help to maintain the foreign confidence deeded for attracting foreign direct investment and securing foreign loans at good terms (Ford and Huang, 1994). It is worthy to rethink the reasons behind such huge foreign reserves in China. For the precaution functions of reserves holding, it is difficult to tell what level should be optimal or adequacy to reach a safety protection. On the other hand, if consider the economic effect, we need to have a standard for foreign reserves to minimise the cost induced by holding. In the special case of China, it is more complicate to confirm a optimal level of reserves because its has a complex economic and political environment. In this paper, we suggest to focus on the management of its reserves holding. 4.2 Suggestions on Management China Foreign Reserves Rregarding huge Chinas foreign reserves, there are theoretical misconceptions that magnifying the function of reserves holding and the more reserves the safety economics are. Under this the view of passive precautionary motive, it is suggested that reserves should not be used until the critical moment. Consequently, foreign reserves have in reality not been effectively utilized although there has been a large pool of them. Reflecting such a view, in the management of foreign reserves, factors such as the economic benefit, social benefit, risk control, efficiency of operation have been ignored. This has led to the management of reserves rigid and inflexible. As mentioned before, foreign reserves are the important part of a countrys monetary policy. Change in reserves is a tool for balancing international payments, and it is usually a result of intervention in the foreign exchange market by the central banks. However, management of the foreign reserve is not only a policy objective, but also a protection of the export competitiveness of domestic enterprises. This is related to measures to boost economic growth and to ensure full employment, both of which are key internal factors in maintaining the balance of development. Therefore, the rapid expansion of reserve should be considered not only for political motives but also the economic motives. It should be worthy to rethink the reserves management measures comprehensively and feasibly. The present condition of foreign reserves in China has been concerned broadly. There is a worry about the potential danger in massive reserves holding which may result in excess load for China. Therefore, it is necessary to adjust measure so as to reduce the risk and even gain profit from the large reserves. For purpose of that, controls the scale of foreign reserves and strengthen monitoring are the key principle of the management. In the present situation, it is more important for China to implement feasible management and make good use of them. China has long implemented the traditional trade strategy which led to sustained trade surplus and rapid expansion of foreign exchange reserves. It would not only exacerbate the pressure for renminbi appreciation, but also carries great risk. Moreover, reforming and maintaining stable renminbi exchange rate regime will be good to the foreign exchange markets which can slowdown the rapid growth in foreign exchange reserves. Apart from reducing its adverse impacts on the macroeconomic, another task is to boost economic growth and establish a new mechanism to transform and use reserves. Further, risk management of foreign reserves should be strengthened and a risk management framework should be established and improved as well. More broadly, the efficiency of reserve operation should be lift. Finally, the capital structures of foreign reserves should be considered in a rational way. According to these directions, we propose some available measures: a) spending and investing foreign reserves; b) gradual liberalization of the capital account; c) reserves hoarding diversification. Since foreign reserves can be regarded as indirect debts of the government against companies and individuals, large foreign reserves could be used to import petroleum and other essential raw materials, high technology, even to invest in key sectors abroad. However, expending and investing reserves would increase liquidity risks problems. Thus, policy decisions on expenditure and investment should be carefully considered based on asset risks. With regarding to capital liberalization, China government always keeps eyes on hot money. It allows efficient capital inflows and reasonable capital outflows through a strictly monitoring system. However, it is difficult to distinguish hot money inflows from normal short-term inflows. Moreover, RMB appreciation and net capital inflows could easily reverse if the government lifts control on capital outflows immediately. In case it happens, foreign reserves holding would still not be sufficient to satisfy the extremely high demand for foreign exchange and this could lead to a financial crisis. Therefore, capital account needs to be monitored before such thing happen. Among the options, diversification would allow China to diversify reserves out of US dollar securities and switch into others countries bonds, given concerns over a weakening US currency. However, US dollar is still the main currency to be used in international payment. No other currency has the similar high level of liquidity as US dollar. Therefore, diversification of reserves asset may add volatility of foreign exchange markets and can catalyze abrupt exchange rate movement. As the result, we suggest the policymakers in China adopt an international reserve diversification standard including disclosure fully of the composition and having gradually adjustment from small scale reserves. 5.0 Conclusion Accumulation of foreign reserves in China was beneficial over the past decade, especially in and in the aftermath of Asian financial crisis. They help to maintain the stability of financial market, expand international trade, attract foreign investment, lower the cost of operation, and enhance financing capacity. Due to a number of positive functions, China has accumulated more and more foreign reserves and surpassed Japan to become the first place in the world from 2006. However, the recent rapid soar has brought about potential risks and worrisome problems for the Chinese economy such as loss of interest and the shrinking of the real value of foreign exchange reserves. In particular, large speculative capital inflows such as hot money have increased risks to the financial system and foreign exchange rate market. It is suggested that large scale foreign reserves in China are more relate to the political factors such as the monetary policy and trade policy. Therefore, it is necessary for China government to make good use of foreign reserves and implement feasible management measures. The suggestions such as a strict control on capital flow, encouraging expenditure and investment with reserve, diversification on reserves holding asset etc are presented from the paper in order to provide available means on reserves management which may reduce risk and address the problem at present. However, these measures feasibility analysis should be put forward in depth so as to find out which is more suitable on the basis of Chinese political situation and financial environment. Foreign reserves continue to increase with a rapid rate in the beginning of 2008. It is sensible to realise that reserves holding should be controlled in a range of reasonable level to maintain the economy in a stably condition. Consequently, Chinese government must beware of this and spend more time on reforming the reserves holding management. It is expected that creative and available options can be implemented in the near future. Note 1 Kenen and Yudin (1965) treated reserves as a discrete-time random walk process which is probably similar to the continuous time Wiener process. Moreover, they argue that central bank reserve holding are sensitive to the volatility in the balance of payments rather than the absolute size of the gap between international payments and receipts. Claassen (1975) also used an inventory model of international reserve choice to explain the restocking costs. Under the FJ null hypothesis, foreign reserves follow a Wiener process until hit the lower zero boundary. After, in a one-step adjustment, reserves jump back up to their optimal restocking level adhere to Wiener process again. 2 Rajan and Bird, (2003) points out this equation is a second-order Taylor-series approximation of optimal reserves holding which isunder the assumption that the special case of no reserve drift between stock adjustments. 3 A key step in taking equation (11) to data is the additional assumption that observed reserves, Rt , are proportional to optimal reserves up to an error term that is uncorrelated with and r.

Gattaca examines science, religion, genetic engineering and ethics Free Essays

By opening the movie Gattaca with quotations from Willard Gaylin and Ecclesiastes, director Andrew Niccol invites us to ponder the tension between science and religion with regard to the ethics of genetic engineering. This tension is further sustained through the complex relationship of the main protagonists Vincent and Eugene, who must ultimately conquer their own physical limitations in order to find â€Å"God†. As the titles run, fingernails, hair threads and skin particles fall to the ground in slow motion, giving way to an image of a young man vigorously scrubbing himself. We will write a custom essay sample on Gattaca examines science, religion, genetic engineering and ethics or any similar topic only for you Order Now Along with a disturbing score by Michael Nyman, this obsessive-compulsive behaviour contributes to the macabre images of hypodermic needles, catheters and hospital bags of urine and blood. The shower from which Vincent has just stepped quickly converts to a furnace (is this heaven or hell? ) while the inter-title â€Å"in the not-too-distant future† runs across our screen. It is the same young man, Vincent, who provides a voice-over and our point of view in Gattaca – the antiseptic setting of a futuristic space program. Here, somnambulistic employees dressed as clones move in and out of a facility designed for cold efficiency. Note the cool blue filters, curved, shining surfaces and, again, a peculiar preoccupation with cleaning. Loudspeakers welcome visitors to Gattaca in various languages demonstrating that, along with space exploration, genetic screening has diminished both the significance and desire for global boundaries. We are already aware that in this future â€Å"blood has no nationality†. For science now enables discrimination that is far more expedient than simply skin colour. Vincent, a â€Å"God† child, is conceived without the help of genetic engineering and is quick to realise that his physical inadequacies, in particular a congenital heart condition, will prevent him from reaching his full potential. It is worth noting that the setting where Vincent’s conception takes place is made â€Å"natural† by the inclusion of beaches and palm trees. As we remain in flashback to where baby Vincent plays with a toy cluster of atoms (similar motifs are repeated throughout the film), we begin to understand the hypocrisy of what this â€Å"brave new world† has to offer. `Genoism† – discrimination on the basis of genetics – is illegal, yet it seems that poor genetic outcomes such as Vincent’s prevents insurance cover, which disqualifies him from pre-school – surely an issue that already has some currency in the world we inhabit today. But although Vincent feels displaced by his genetically superior brother , Anton (note how he walks into the frame just as Vincent tears his own image out of the family snapshot), he is determined to fulfil his dream of space travel. The initial swimming race where Vincent is beaten by Anton serves as a plot device pre-empting the climax of the film where both brothers, now adults, play â€Å"chicken† once again. Aerial shots intensify a terrifying sea and, this time, Vincent’s victory. The irony is stark as Niccol underlines the central theme of the film – what constitutes a â€Å"valid† human being? For surely Vincent, an â€Å"invalid†, has just proved that genetics has little influence over sheer determination and grit. Enter Eugene. Genetically flawless but crippled both physically and emotionally from a suicide attempt (he finished second, not first, in a swimming race), he is continually compared with Vincent, whose genetic profile dictates that he will die at the age of 30. Eugene is bitter and twisted while Vincent is single-minded and driven. Both, however, are essentially blind to what it is that makes them human. Vincent, desperate to conceal his identity from Irene, is nearly run down on a frenetically busy highway, whereas Eugene deliberately steps in front of a car in the hope of bringing about his own death. Both are so preoccupied with their own deficiencies that they almost miss their important â€Å"spiritual† journey. In fact, both these men run perilously close to becoming like Anton – robotic and devoid of emotion. It is Anton who provides the real paradox here by ruthlessly investigating his own brother’s â€Å"invalidity† and, in so doing, demonstrates that genetics does not necessarily correlate with one’s humanity. Indeed, it is Irene who, from the outset, seems to be more in touch with the natural world towards which Vincent is striving to return. Note the setting where she lives; rolling surf, pristine white sand, the warm light within in which she is constantly bathed, her disappointment with Vincent’s supposed â€Å"perfection†, her fascination with the sunrise, her ability to notice the change in his eyes after he discards his contact lenses when most people can only recognise human differences by a DNA test. Irene’s costume and hair are much softer, feminine and distinctively individual when she is away from Gattaca. Yet our focus continually returns to Vincent and Eugene, whose relationship not only dominates most of the film’s running time but develops an intimacy that is as selfless as it is full of love. The overt twinning effect (Eugene operates as Vincent’s doppelganger) combined with the homoerotic subtext belies any real attempt by Niccol to establish a meaningful connection between Vincent and Irene, with the latter finally reduced to â€Å"nominal love interest†. In an effort to conceal Vincent’s identity, Eugene’s loyalty is clearly demonstrated when, slowly and painfully, he drags his broken body up the spiral staircase – remember, he’s scared of heights. Reminiscent of a DNA strand, the staircase is a metaphor for transcendence, for raising ourselves to a new level of understanding. Eugene, determined that Vincent too will break free of his earthly bounds – his physical being – recognises the symbolism when he refers to space as â€Å"upstairs†. Earlier, Vincent tells Eugene that weightlessness is like being in the womb and that in space his legs â€Å"wouldn’t matter†. But in the end, Eugene returns to where Vincent originally emerged (this time to a self-determined cremation), his sacrifice complete as Vincent is released into space. The gift of the lock of hair is on one level a safeguard against Vincent’s disclosure but on another a unique and somewhat childlike reminder of Eugene’s innocence in a world gone mad with science and its attending preoccupation with perfection. It is Eugene who occupies Vincent’s thoughts at closure, not Irene. Despite having overcome their genetic and physical dispositions, it is clear there is no real â€Å"place† for either of these men on earth. By accentuating the tunnels leading back to the womb-like spaceship and the foetal position of Eugene in the furnace, Niccol has both Vincent and Eugene return to where science and religion originate – back to the stars, back to God, back to â€Å"home†.

Derivational Morphology free essay sample

Bound Morphemes like-ify and –cation are called derivational morphemes. When they are added to base, anew word with a new meaning is derived ? Example : The addition of –ify to pure= Purify means â€Å"to make pure† The addition of –cation to purify= Purification means â€Å"the process of making pure†. ? This means that we must have a list of the derivational morphemes in our mental dictionaries as well as the rules that determine how they are added to a root or stem. The form that results from the addition of derivational morpheme is called a derived word. ? Derivational Morphemes have clear semantic content. ? In this sense they are like content words, except that they are not words. ? As we have seen, when a derivational morpheme added to a base, it adds meaning. ? The derived word may also be of a different grammatical class than the original word, as shown by suffixes such as –able and-ly ? Example : When a verb is suffixed with –able the result is an adjective, as in desire +able = desirable When the suffix –en is added to an adjective, a verb is derived, as in dark +en = Darken When =ie is added to an adjective, a noun is formed, as in sweet +ie = sweetie Other examples: Noun to adjectiveVerb to Noun Adjective to adverb boy+-ish= Boyish clear+-ance = clearanceexact+-ly = exactly virtue+ -ous= virtuoussing+-er=singerclear+-ly =clearly Noun to VerbAdjective to NounVerb to Adjective moral+-ize= Moralizetall+-ness= tallnessread+-able=readable hast+-en=hastenfree+-dom=freedomcreate+-ive= creative ? Some derivational suffixes do not cause a change in grammatical class. We will write a custom essay sample on Derivational Morphology or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Prefixes never do. Examples: Noun to NounVerb to VerbAdjective to Adjective friend +-ship = friendshipun- + do= undopink+-ish= pinkish ? Derivational affixes appear to come in two classes. In one class, the addition of suffix triggers subtle changes in pronunciation. Example: when affix –ity to specific (pronounced specific with a k sound), we get specificity (pronounced â€Å"specifisity† with an s sound) When deriving Elizabeth +an from Elizabeth, the fourth vowel sound changes from the vowel in Beth to the vowel in Pete. Other suffixes such as –y,-ive, and –ize may induce similar changes : sane to sanity, deduce to deductive ? On the other hand, suffixes such as –er,-ful,-ish,-less,-ly and-ness may be tacked onto a base word without affecting the pronunciation, as in baker, wishful, boyish, needless, sanely, and fullness ? Moreover, affixes from the first class cannot be attached to base containing an affix from the second class: need+ less+ ity, Moral = ize; but affixes from the second class may attach to bases with either kind of affix: moral =ize = er, need + less +ness. INFLECTIONAL MORPHOLOGY: ? Function words like to, it, and be are free morphemes. Many languages, including English, also have bound morphemes that have a strictly grammatical function. ? They may change properties such as tense, number, person, case, gender. Such bound morphemes are called inflectional morphemes ? Unlike derivational morphemes, they never change the grammatical category of the stems to which they are attached. Consider the forms of the verb in the following sentences: English Inflectional MorphemesExamples -sthird person singular presentShe wait-s at home. -edpast tenseShe wait-ed at home. -ingprogressiveshe is eat-ing the donut. -en past participleMary has eat-en the donuts. s pluralShe ate the donut-s -‘spossessiveDisa’s hair is short. -ercomparativeDisa has short-er hair than Karin. -estsuperlativeDisa has the short-est hair. ? Inflectional Morphemes in the English follow the derivational morphemes n a word. Thus, to the derivationally complex word commit +ment one can add a plural ending to form commitments, but the order of affixes may not be reversed to derive the impossible commit+s+ment= commitsment. ? Another distinction between inflectional and derivational morphemes is that inflectional morphemes are PRODUCTIVE: they apply freely to nearly every appropr iate base ( excepting â€Å"irregular† forms such as feet, not foots). ? Most nouns takes an –s inflectional suffix to form a plural, but only some nouns take the derivational suffix-ize to form a verb† idolize but not picturize. In distinguishing inflectional from derivation morphemes we may summarize as follows: INFLECTIONALDERIVATIONAL 1. Grammatical function1. Lexical function 2. No word class change2. May cause word class change 3. Small or no meaning change3. Some meaning change 4. Often required by rules of grammar4. never required by rules of grammar 5. Follow derivational morphemes in a word5. precede inflectional morphemes in a word 6. Productive6. Some productive, many non- productive

The Superiority of Word Processor to Paper and Pencil an Example by

The Superiority of Word Processor to Paper and Pencil Paper and pencil was long ago the original means of documentation, the advent of electronics means in the late 1960s by IBM (International Business Machine) generated arguments on the economic implications to the manufacturers of paper and pencil. Despite the invention of easy documentation and swift processing to finishing hard copy, it is of note worthy that the importance of pencil and paper usage in documenting data is still of importance in the present world. Need essay sample on "The Superiority of Word Processor to Paper and Pencil" topic? We will write a custom essay sample specifically for you Proceed Though some may insist that recording data with word processor is superior to pencil and paper, I still question the persistent flying around of paper and pencil in the country and even in nations abroad in terms of existence far back in the beginning, paper and pencil has been in use and its place so far has not been occupied with the advent of word processor. This simply emphasizes that the word of documentation can hardly do without the ancient material. Even the so called word processor would need manuscript collection before the final input to electronic word processor software in computer system. In this regard, word processor is somehow dependant on paper and pencil instructions from the author. The appreciation of the use of word processor on the other hand must be pronounced. Excellence in documentation in the recent world requires direct slotting of data into computer system right away without holding paper and pencil. I still argue that the time consumed in multiple exercise of thinking, typing and editing equate the time spend on word processor to manual writing. May be they are right anyway, since the paper and pencil application would still require the touch of electronic word processing before final produce into circulating copies. One wonders how long it will take to produce handy copy of speech presentation to thousand of audience in a conference. Weighing the two sides, my unbiased view would agree with the category of intellectuals that believe in the superiority of word processor to paper and pencil.

Rates of Change Worksheets with Solutions

Rates of Change Worksheets with Solutions Prior to working with rates of change, one should have an understanding of basic algebra, a variety of constants and non-constants ways in which a dependent variable can change with respect to changes in a second independent variable. It is also recommended that one has experience calculating slope and slope intercepts. The rate of change is a measure of how much one variable changes for a given change of a second variable, which is, how much one variable grows (or shrinks) in relation to another variable. The following questions require you to calculate the rate of change. Solutions are provided in the PDF. The speed at which a variable changes over a specific amount of time is considered the rate of change. Real life problems as those presented below require an understanding of calculating the rate of change. Graphs and formulas are used to calculate rates of change. Finding the average rate of change is similar to a slope of the secant line that passes through two points. Here are 10 practice questions below to test your understanding of rates of change. You will find PDF solutions here and at the end of the questions. Questions The distance a race car travels around a track during a race is measured by the equation: s(t)2t25t Where t is the time in seconds and s is the distance in meters. Determine the car’s average speed: During the first 5 secondsBetween 10 and 20 seconds.25 m from the start Determine the instantaneous speed of the car: At 1 secondAt 10 secondsAt 75 m The amount of medicine in a milliliter of a patient’s blood is given by the equation:M(t)t-1/3 t2Where M is the amount of medicine in mg, and t is the number of hours passed since administration.Determine the average change in medicine: In the first hour.Between 2 and 3 hours.1 hour after administration.3 hours after administration. Examples of rates of change are used daily in life and include but are not limited to: temperature and time of day, rate of growth over time, rate of decay over time, size and weight, increases and decreases of stock over time, cancer rates of growth, in sports rates of change are calculated about players and their statistics. Learning about rates of change usually begins in high school and the concept is then re-visited in calculus. There are often questions about the rate of change on SATs and other college entry assessments in mathematics. Graphing calculators and online calculators also have the ability to calculate a variety of problems involving the rate of change.

Nursing and the Media Essay Example | Topics and Well Written Essays - 250 words

Nursing and the Media - Essay Example The media can either positively or negatively influence the public image of nursing depending on the stories, news, or advertisements on nursing broadcasted to the public. The media can positively impact on the public image of nursing through broadcasting shows/films of nurses working to save victims of natural disasters like earthquakes and hurricanes and news stories relating to nurses importance to a safer public positively affected nursing and aided in augmenting respect for nurses (Donelan et al., 2008). However, news. Films, or advertisements on nurse’s strikes and nurses not taking their duty well in terms of caring for the patients and participating in unethical behavior endangering the lives of the patient's results in a negative public image of nurses. News relating to nurse shortage and the general outlook on nursing as a career does not positively or negatively impact on the public image of nurses (Donelan et al., 2008). Avenues of educating the general public include nurses writing articles in newspapers aimed at informing the public regarding nursing roles and scope and changing health care system. Other avenues include posting and circulation of nursing accomplishments, making announcements in dailies, nurses speaking to civic and community groups on nursing roles and responsibilities. Other avenues are posting online in blogs and on social media sites and contacting media outlets and program developers on the need to portray nursing in a positive manner and in the true light of nursing roles and scope.

Portfolio - Essay Example The graduate employers find it hard to fill up the vacancies in spite of receiving innumerable applicants because of the shortage of good quality graduates. It is now utmost important for the applicant to consider what constitute the good quality graduates. However, there has been a shift in the preferences and expectations of the employer when it comes to graduates and the skills that they suppose them to possess. The organisations prefer to have people with firm or industry specific knowledge (Scribd, n.d.). Preferred Job Area After completion of my graduation, I wish to work as a ‘Human Resource Officer’. The respective field has been chosen as I have always been interested in the Human Resource related activities. The task of the human resource officer is to provide advice and implement policies that relates to the effective use of the personnel within the organisation. The main aim of the human resource officer is to ensure that the organisation employs right balanc e of the staffs according to their knowledge and skills. They also need to check if the training and development opportunities are made available to the employees in order to enhance their performances. The human resource officer needs to have a clear understanding of what the objective of the employers business is and they must be able to make and implement the policies that helps to select, develop as well as retain the correct staff which is required to meet these objectives. There has been change in the character of the HR professionals. The nature of the work of the human resource profession varies according to the organisation. However, it is likely to include working in tandem with the departments, liaising with the wide range of people that is involved in the policy areas such as staff performance, their health and safety, negotiating with the staffs and their representatives on matters related to the pay and condition, administering the payroll and the maintenance of the em ployee record (Prospects, 2010). Various organisations offers HR Officers job in the UK. Few of them are United Response, Huntress Search Limited and Candidate Source Limited (Monster, 2010). United Response is a charity that works across England and Wales. It caters support to the people who have various disabilities (United Response, 2010). The recruitment process of the United Response is quite simple. The candidate needs to register online. The candidate will be required to answer few simple questions and then they can either qualify for an interview on the day of recruitment or on some other day (United Response, 2010). Huntress is one of the most creative, active and rapidly growing recruitment groups. It is a multi award wining company having 18 centres in the UK. It is soon going to expand its operation both internationally and domestically (Huntress Commercial, n.d.). The company requires that the candidate should have certain kind of generalist HR experience and must be ab le to deal with various kinds of HR issues (Monster, n.d.). Networx is another famous company based in the UK, Leicestershire. The company work together with the clients and the candidates and tries to deliver a qualitative professional service that not only focus upon the time and the cost efficiency, but also put stress upon the

What's in a Name Essay Example | Topics and Well Written Essays - 250 words

What's in a Name - Essay Example Such a move is described as customer driven since it puts the interests of the customer at the fore front. According to the articles history, most celebrities have found it difficult to find a suitable name for their children. This has made them to adopt funny names that may have an impact in the child’s life. By capitalizing on this situation, Maryanna expects to serve new parents who are unable to come up with good names. In overall, parents and new born are her target market. Maryanna would receive a lot of competition from companies that manufacture baby care products. It is evident that such companies have their own name experts who are charged with the responsibility of naming baby products. Baby products are always required to be in sync with catchy names. Such names may form clues to parents on how to name their children (Osborn, 2009, p.245). By being able to name children on their own, the parents won’t need those services of Maryanna thereby threatening her business. There are other companies that specialize in naming celebrity children. Such companies pose a great challenge to Maryanna since they are engaged in the same line of business. Such situations may lead to one of them diversifying into other fields thereby incurring unwanted costs (Osborn, 2009,

The Ten Principles of Economics

The Ten Principles of Economics PART 1: Principle 1: PEOPLE FACE TRADEOFFS: To get something one has to sacrifice other thing. For example, a country can spend its maximum resources for its defence but at the same time, it has to sacrifice the maximum spending for the country welfare. A society also faces tradeoffs between the Efficiency and Equity. The government generally tax rich people so that it can get the money from them and use it for the welfare of the poor people; this brings the equity but reduced the efficiency. (Mankiw,2003,p.5) Principles 2: THE COST OF SOMETHING IS WHAT YOU GIVE UP TO GET IT: Since we do tradeoffs, the people generally find out the cost and benefits that their action going to incur. For an action, one has to sacrifice something. For example: I have come here to do post-graduation but I had to sacrifice my server administrator job. A cost that given up to get something known as the opportunity cost. My opportunity cost is server administrator job, money, and time, which I had given up for the post-graduation. (Mankiw,2003,pp.56) Principle 3: RATIONAL PEOPLE THINK AT THE MARGIN: (Refer appendix (a)) One always does small changes in their plan of action to achieve maximum benefits from the process. (Mankiw,2003,p.6) This small change known as the marginal changes as it take place around edges. For example: A student who is enrolled for 1 year of education, if he/she add one more year to its study, they will be able to apply for permanent residency which incur as additional benefits but with this come the additional costs of college fees, time etc. Comparison of marginal benefits and marginal cost will be able to help you in taking the decision. Principle 4: PEOPLE RESPOND TO INCENTIVES: Behaviour of any person or firm changes according to the environmental variables like benefits or cost changes. For example: If the cost of the orange increases then the consumer will shift towards apples, as cost of orange is high. (Mankiw,2003,p.7) Principle 5: TRADE CAN MAKE EVERYONE BETTER OFF: Trade is taking place between the products that countries own not between the countries. (Chapter 1,p.4) (Refer appendix (b)) Trading between parties makes goods cheaper. For example: Trade between country A and country B will help both the countries to get goods of one another and help them to expertise in what they are good at producing. Principle 6: MARKETS ARE USUALLY A GOOD WAY TO ORGANIZE ECONOMIC ACTIVITY: Market Economy is the concept where a centralise judgment planner is substituted by judgement of millions of households and firms. The place where the households and firm can communicate with each other for services and goods is known as market and it is taken place under the influence of the price and self-interest, which helps them to take decision. For example: Taxes that impose by the government always change the goods price and decision of producer and consumers. (Mankiw,2003,p.9) Principle 7: GOVERNMENTS CAN SOMETIMES IMPROVE MARKET OUTCOMES: When a market fails to distribute the resources efficiently, it is known as market failure, which decreases efficiency. Government impose some rules to improve the market.(Mankiw,2003,p.11) For example: When the Australian government, impose carbon tax on the emission of the carbon, which will makes the firm to emit less carbon, which results in less pollution. (Kirk,2010) Principle 8: A COUNTRYS STANDARD OF LIVING DEPENDS ON ITS ABILITY TO PRODUCE GOODS AND SERVICES: The living standard in the country is depends upon the country producing capacity. In country where, more goods and service are produced in a unit time there standard of living is high as compared to the people with less productivity. For example: Living standard of a U.S. citizen is better than living standard of Mexican and Nigerian citizen as a U.S. citizen earn more than those two citizen. . (Mankiw,2003,p.12) Principle 9: PRICES RISE WHEN THE GOVERNMENT PRINTS TOO MUCH MONEY: Inflation is the state in which the price level increases in the economy. Inflation occurs when the supply of the money, which is under the hood of government, increased drastically in compare to the accessibility of services and goods in the markets.(Chapter 1, p.6) When the government produce high quantity of nations money, than it has lose its value. For example: When in Germany the average price of the commodity is tripling every month so the production of money is also tripling every month. .(Mankiw,2003,p.14) Principle 10: SOCIETY FACES A SHORT-RUN TRADEOFF BETWEEN INFLATION AND UNEMPLOYMENT: Policy that are making, to reduce the inflation led to increase in unemployment and policy to reduce unemployment led to increase in inflation this properly describe in Philip curve. This concept ends in 1970 when inflation and unemployment co-existed at their maximum peak. (TEN (10),p.3) The relationship between the inflation and unemployment is temporary. (Mankiw,2003,p.14) Answer 2: The study, which deals with the choices made by an individual and business, the way in which this choices are communicate with each other in a market environment and the effect of the government on them, is known as Microeconomics. Example: Study of people behaviour of buying more laptops? The study, which deals with the performance of the global economy and the national economy, is known as Macroeconomics. Example: Government rule and taxation on particular goods. (McTaggart,Findlay,andParkin2007,p.4). Key player, which are present in the market environment, are the producer, consumer and the government. Decision of the producer to produce goods, entering or exiting the market comes under the microeconomics, which is the individual decision of firm.(OECD,p.34) A firm will always take a decision to maximize its profit. Regulations made by the government, affect firm decision, as unnecessary restriction will increases firms cost and decreases its productivity, which results in the firm loss comes under macroeconomics. (Loayza,p.6) PART 2: Answer 3: Supply curve: A supply curve is the curve, which shows the relationship between the price of the goods and the quantity supplied when all the elements acting on the producer scheduled sales remains the same. Supply curve is upward sloping. (McTaggart,Findlay,andParkin2007,p.66). In Figure-1, as the price is increasing the supply of the apples are also increasing for 0.40 supply was 1,000 and for 0.60 supply was 2000. This implies that it follows the law of supply. Price ($ per pound) Apples per day (pounds) supplied 0.40 1000 0.60 2000 0.80 3000 Figure-1 Source: Collins Karen Demand curve: A demand curve shows the relationship between the price of the goods and the quantity demanded when all the elements acting on the consumers schedule buying remain the same. Demand curve is downward sloping. (McTaggart,Findlay,andParkin2007,p.62). In Figure-2, as the price is decreasing the demand of the apples are increasing for 0.80 demand was 1,500 and for 0.40 demand was 2,500. This implies that it follows the law of demand. Price ($ per pound) Apples per day (pounds) demanded 0.80 1500 0.60 2000 0.40 2500 Figure-2 Source: Collins Karen Equilibrium of a market: When two opposite forces balance each other, this state is known as the Equilibrium state. Market equilibrium is the state when the buyer and seller both of them are satisfied with the price of the commodity. Condition that satisfies the equilibrium is that, when the demand of the quantity is equal to the supply of the quantity. (McTaggart,Findlay,andParkin2007,p.70). In Figure-3, the intersection point of the demand curve and the supply curve is the equilibrium point where the apples demanded is equal to the apples supplied. Price ($ per pound) Apples per day (pounds) demanded Apples per day (pounds) supplied 0.80 1500 1000 0.60 2000 2000 0.40 2500 3000 Figure-3 Source: Collins Karen Answer 4: A chemical equilibrium is the state at which the rate of the forward reaction is equal to the rate of the reverse reaction. (Refer appendix (c)) This simply tells us that the rate of forming of the products is equal to the rate of forming of the reactants. (sparknotes,2009) For example: N2+3H2 à ¢Ã¢â‚¬ ¡Ã¢â‚¬Å¾ 2NH3 The reaction shows us that when hydrogen reacts with nitrogen they form the ammonia gas, NH3. During the first interaction between the nitrogen and hydrogen in the chamber, ammonia is generated. When the concentration of ammonia increases the ammonia gas start to breakdown into the nitrogen and hydrogen. When the rate of forming of ammonia is equal to the rate of decomposition of the ammonia then that state is known as the equilibrium state. (Refer appendix (d)) (Chemistry Explained,2010) When we contrast the concept of the chemical equilibrium to the concept of the economics they are the same as both the equilibriums need one condition to satisfy quantity demanded = quantity supplied, (Refer appendix (e)). At the equilibrium, the forward reaction, which is to equivalent to the quantity demanded in economics, is satisfied by the reverse reaction, which is equivalent to the quantity supplied in economics. In economics for quantity demand, there is always supply of goods, which is never ending process as in chemical reaction at equilibrium state it is also a never-ending process. Equilibrium is very important in economics because if there is no equilibrium than there will be shortage or surplus of the goods which will results higher price for goods or lower price of goods, which will make both the consumer and producer unhappy as at the equilibrium stage the price that a seller will be happy to sell its good and a buyer is happy to pay for it. (McTaggart,Findlay,andParkin2007). Answer 5: D TCS S=MC Price P* E(D=S) S D=MB TPS Q* Quantity Graph 5(i) For resource allocation we have to prove MB (marginal benefits)=MC(marginal costs) and maximum welfare = Consumer surplus + Produces surplus. In the Graph 5(i), We have supply curve S, which also represent marginal cost, and demand curve D, which also represent marginal benefits. The intersection of the curve D and S is the equilibrium that is where demand = supply which also means the marginal benefits = marginal costs. At this point the P* and the Q* is the price and quantity that will be our competitive outcome. In DES, (TCS) for the consumer surplus, P*ED represent the total consumer surplus that is maximum consumer benefits and for the (TPS) producer benefits it is the P*ES represent the total producer surplus that is maximum producer benefits. Because P* and the Q* is the competitive outcome as E is the point of equilibrium. P*ED and P*ES is congruent as DP*=SP* and angle DP*E=SP*E (P* is the mid-point of SD) In Graph 5 (i), we have proven that marginal benefits= marginal cost is the efficient outcone. Any government intervention like tax or subsidy is harmful to economy because as Taxes in the economy makes the buyer to pay more and seller to get less. Therefore, it will make the producer to produce less that is that will lead to the underproduction of the product. Subsidies that are given to producer by the government lessen the cost paid by the buyers and seller receives the high price. Therefore it will lead to produce more so over production. D TCS S=MC D S Price P* E(D=S) D3 D2 S D=MB TPS Q1 Q* Q2 Quantity Graph 5 (ii) In Graph 5 (ii), competitive outcome is P* and Q*. It shows that D2DE, is the part which we are losing (Dead weight loss) as Marginal CostMarginal Benefits, firm is producing Q2quantity, that is firm is over producing, right of Q* firm will produce more quantity. In both the cases we are deviating from the competitive outcome so it is inefficient. (McTaggart,Findlay,andParkin2007,pp.114 116). PART 3: Answer 6: When some of the free market is not able to allocate the resources proficiently then it is a market failure. (Mankiw,2003,p.151). It can be, the resources are under allocated so goods are under produced and vice-versa. The Pollution problem resulting to global warming is example of market failure.(Market Failure,2010) To overcome this situation the government can comes with some rules and regulation. For example: Australian government impose the tax on the carbon emission known as carbon tax. There is a belief in this step that, to avoid the extra tax or money to pay the people will choose to emit less carbon, which will result in the reduction in the national emissions. (Brook Barry,2009) Answer 7: I think governments tend to interfere in economic activity more than what economic theory recommends because there is always a debate between the efficiency and equity. Efficiency is a concept telling us, what is the maximum amount of output a society gets from its scarce resources. Equity is dealing with the equally distribution of the economic outcome fairly among the society. (Mankiw,2003,p.5).For this thing to explain, I am taking example of Australian Government. The government introduces the mining tax and provide an argument, that the Australian people are the candidate to receive maximum share of the profits generated by the mining. This mining tax come into action, as the mining company pay royalties to state government, which is 40% of their profits, in 2001, but in present they are paying less than 20%. (Mining Tax) Answer 8: A fundamental right of every personal, to manage their individual property and labour, is known as Economic freedom. An individual person is free to consume, produce, work, and do the investment in their way, in economically free society and protection of the freedom is by state. Movement of goods, capital, and labour is free in the economically free society. To measure index of economic freedom we measure ten modules of economic freedom on the scale of 0 to 100, 100 being the maximum freedom. The 10 modules score is totalled and average is taken out for the every country, which is index of economic freedom. Economic freedom modules, which are used for the measurement of economic freedom index are, freedom of business: free to operate the business, freedom of trade, fiscal freedom, spending of government, freedom on monetary, freedom of investment, freedom in finance, property rights, freedom from corruptions and labour freedom.(2010IndexofECONOMICFREEDOM) Four countries that have moved up the scale in 2010: New Zealand, Switzerland, Japan, Sweden. Four countries that have moved down the scale in 2010: Hong Kong, Singapore, India, United States. (RankingtheCountries,2010) Answer 9: Australia stand on the third position in the Economic Freedom Index scale of 2010. Its overall score of 82.6 in 2009 remain unchanged in the 2010 as it did not move up or down in the scale of index. Good macroeconomics policies help the Australian economy to survive the recent financial crisis. (Australia,2010) For further improvement in the Australian business environment, we can use supply chain intelligence in the business (DysonEvelynLaurel), use of the business excellence framework, (BusinessExcellence,2010) improving the environment. PART 4: Answer 10). S I1 P2 E2 P1 E Price E3 D2 P3 I2 D3 D1 Q3 Q1 Q2 Quantity Æ’Â   Graph 10 (i) In perfectly competitive grocery market, under short run, the numbers of firms are constant and each firm has certain plant size. In the Graph 10(i), D1 is a demand curve and S is the supply curve of grocery industry. E is the equilibrium point, and P1 and Q1 are equilibrium price and the quantity of grocery industry. If, there is change in demand then there is also change in the short-run equilibrium. When the demand of grocery increases (I1), the demand curve will shift towards right, D2, E2 is the new equilibrium point with equilibrium price P2 and equilibrium quantity Q2 it the point when the firm will maximize the profit by maximizing the output. When the demand of grocery decreases (I2), the demand curve will shift towards left, D3, E3 is the new equilibrium point with equilibrium price P3 and equilibrium quantity Q3 it the point when the firm will maximize the profit by decreasing the output. If demand curve shift more left than D3 than firm in grocery industry, will temporari ly close down its facility or will continue to produce Q3 quantity by bearing loss. S1 I1 P1 E1 S0 P0 E0 Price D Q1 Q0 Quantity à ¢Ã¢â‚¬  Ã¢â‚¬â„¢ Graph 10 (ii) In the Graph 10(ii), any price above the P0, firm in grocery industry will make economic profit and below P0, economic loss and at P0 zero economic profit. Demand curve is D. Supply curve of the grocery industry is S1, so things sold at P1 with Q1 quantity will produce economic profit and attract the other new firm. As new firm enter, supply will increase, so grocery industry supply curve will shift right (I1) to S0. As the demand is unchanged, market price will drop from P1 to P0 but quantity produce is Q1 to Q0 (increases). Therefore, economic profit of exiting firm in a grocery industry decreases but output from grocery industry increases. For the consumer: The consumer will able to get the grocery at lower price. (McTaggart,Findlay,andParkin2007,pp.234235). Answer 11). Using Kinked Demand Curve Model: Assumption: If the firm1 in grocery industry, increases its price than the firm2 will not follow but firm1 decreases than firm2 will also decreases its price P MC1 MC0 Price A B D MR Q Quantity Graph 11(i): In the Graph 11(i), the firm in the grocery industry having the Graph 11(i). Therefore, P is the price for the market, and D is the demand curve of the firm. If the firm increase its price P, then that firm will see that there is a greater decrease in its quantity sold because the other firm is not going to increase the price. If the firm sell, its goods below price P than there is little increase in the goods selling as other firm will also cut there price. As the demand curve is kinked so the MR, Marginal revenue is having a break AB. Maximum profit of the firm is generated at quantity Q as the marginal cost (MC) = marginal revenue (MR) i.e. intersection of MR and MC at gap AB. If there is fluctuation of MC between the A and B, the firm is not going to modify its quantity or price. If the fluctuation takes place outside the AB, so firm going to change its price and quantity. Small change in the cost is not having greater effect on price or quantity. (McTaggart,Findlay,andParkin2007 ,p.288). If the two firms collude than it may happen that, they cheat or comply with each other. In the below table after applying game theory and players are two firm, firm1 and firm2 and they play for once. FIRM1: If firm 2 cheats, and if firm 1 cheats it gets 2M and if it comply than it loses 3M so 2M is better. If firm 2 comply and if firm 1 cheats it get 8M and if it comply than it gain 4M, so 8M is better than 4M. Therefore, it tells that the Firm1 should cheats. FIRM2: If firm 1 cheats, and if firm 2 cheats it gets 2M and if it comply than it loses 3M so 2M is better. If firm 1 comply and if firm 2 cheats it get 8M and if it comply than it gain 4M, so 8M is better than 4M. Therefore, it tells that the Firm2 should cheats. FIRM 1 FIRM 2 Cheat Comply Cheat (2M, 2M) (-3M,8M) Comply (8M,-3M) (4M,4M) (Playoffs: Firm1, Firm2) According to the Nash equilibrium, both of them will cheat, as the cheating is the best strategy for them and earn 2M. If the game is played for the indefinitely than the both the firm will come to know that if they comply they have better result, that is each firm will going to get 4M, which is greater than 2M. Indefinite playing will give firm to get the best outcome. (McTaggart,Findlay,andParkin2007,p.303). Answer 12). In NASH equilibrium, one company develops its best possible strategy according to the strategy adopted by another company and vice versa. Normal equilibrium where the buyer and seller both of them are satisfied with the price of the commodity. In NASH equilibrium, there is no role of price but information and strategy plays an important role but in normal equilibrium price plays an important factor to attain the equilibrium. (McTaggart,Findlay,andParkin2007).
