does exchange rate variability depress trade flows evidence from error correction models this paper examines the impact of exchange rate volatility on the trade flows of the g 7 countries in the context of a multivariate error correction model the error correction models do not show any sign of parameter instability the results indicate that the exchange rate volatility has a significant negative impact on the volume of exports in each of the g 7 countries assuming market participants are risk averse these results imply that exchange rate uncertainty causes them to reduce their activities change prices or shift sources of demand and supply in order to minimize their exposure to the effects of exchange rate volatility this in turn can change the distribution of output across many sectors in these countries it is quite possible that the surprisingly weak relationship between trade flows and exchange rate volatility reported in several previous studies are due to insufficient attention to the stochastic properties of the relevant time series copyright 1993 by mit press

nonlinear effects of exchange rate volatility on the volume of bilateral exports in this paper we investigate empirically the impact of exchange rate volatility on real international trade flows utilizing a 13 country data set of monthly bilateral real exports for 1980 1998 we compute one month ahead exchange rate volatility from the intra monthly variations in the exchange rate to better quantify this latent variable we find that the effect of exchange rate volatility on trade flows is nonlinear depending on its interaction with the importing country s volatility of economic activity and that it varies considerably over the set of country pairs considered copyright 2003 john wiley sons ltd

accounting for a shift in term structure behavior with no arbitrage and macro finance models this paper examines a shift in the dynamics of the term structure of interest rates in the u s during the mid 1980s we document this shift using standard interest rate regressions and using dynamic a ne no arbitrage models estimated for the pre and post shift subsamples the term structure shift largely appears to be the result of changes in the pricing of risk associated with a level factor using a macro nance model we suggest a link between this shift in term structure behavior and changes in the dynamics and risk pricing of the federal reserve s in ation target as perceived by investors

deviations from purchasing power parity in the long run this paper demonstrates that deviations from purchasing power parity reveal a remarkable and possibly startling consistency with martingale behavior during both fixed and flexible rate periods for a wide variety of countries and in both monthly and annual data since this pattern appears to be much more general than one would expect on the basis of models founded on international commodity arbitrage the paper proposes an alternative explanation which instead relies on financial arbitrage in bonds as the underlying mechanism this paper will demonstrate that deviations from purchasing power parity ppp reveal a remarkable and possibly startling consistency with martingale behavior during both fixed and flexible exchange rate periods for a wide variety of countries and in both monthly and annual data this pattern appears to be much more general than one would expect on the basis of models founded on international commodity arbitrage the paper therefore proposes an alternative explanation which does not presuppose free trade in goods but which instead relies on financial arbitrage in bonds as the underlying mechanism the major implication of the theory and the results is that ppp is as likely to be violated in the long as in the short run as an empirical matter deviations from ppp can be observed for most currencies at any instant see kravis et al 21 stockman 37 and genberg 15 among others these deviations are typically both cumulative and persistent the real exchange rate can remain on either side of parity for lengthy but variable time intervals of a year or more as a consequence the current consensus shared

has the european monetary system led to more exports evidence from four european union countries abstract we attempt to investigate whether the exchange rate mechanism erm period has coincided with an increase in intra eu exports we conclude that this has not been the case but it is likely that the elimination of nominal exchange rate variability arising from a single currency will boost intra european union trade

evaluating natural resource investments notwithstanding impressive advances in the theory of finance over the past 2 decades practical procedures for capital budgeting have evolved only slowly the standard technique which has remained unchanged in essentials since it was originally proposed see dean 1951 bierman and smidt 1960 derives from a simple adaptation of the fisher 1907 model of valuation under certainty under this technique expected cash flows from an investment project are discounted at a rate deemed appropriate to their risk and the resulting present value is compared with the cost of the project this standard textbook technique reflects modern theoretical developments only insofar as estimates of the discount rate may be obtained from crude application of single period asset pricing theory but see brennan 1973 bogue and roll 1974 turnbull 1977 constantinides 1978 the inadequacy of this approach to capital budgeting is widely acknowledged although not widely discussed its obvious deficiency is its the evaluation of mining and other natural resource projects is made particularly difficult by the high degree of uncertainty attaching to output prices it is shown that the techniques of continuous time arbitrage and stochastic control theory may be used not only to value such projects but also to determine the optimal policies for developing managing and abandoning them the approach may be adapted to a wide variety of contexts outside the natural resource sector where uncertainty about future project revenues is a paramount concern

on the sensitivity of the volume and volatility of bilateral trade flows to exchange rate uncertainty we present an empirical investigation of the hypotheses that exchange rate uncertainty may have an impact on both the volume and variability of trade flows by considering a broad set of industrial countries bilateral real trade flows over the period 1980 1998 similar to the findings of earlier theoretical and empirical research our first set of results shows that the impact of exchange rate uncertainty on trade flows is indeterminate our second set of results provides new and novel findings that exchange rate uncertainty has a consistent positive and significant effect on the volatility of bilateral trade flows helping us better understand macroeconomic volatility jel f17 f31 c22

exchange rate volatility and aggregate export growth in bangladesh the long and short run determinants of bangladeshi export growth are examined these are modelled as depending on world trade volume bangladeshi and world export prices and exchange rate volatility several techniques are used to estimate and test hypotheses about the cointegration space of these variables we find that there are two plausible restricted cointegrating vectors one appears to be an export demand while the other is suggestive of an export supply these are then imposed on an error correction model estimates suggest that in the long run bangladeshi export growth is driven by the volume of world trade and is negatively and inelastically related to the volatility of bangladeshi exchange rates once these long run effects are accounted for it is found that none of the variables significantly explains any short run changes in export growth

the collapse of purchasing power parities during the 1970 s one of the striking facts concerning the relationship beiveen prices and exchange rates during the 1970 s has been the dismal performance of the predictions of the simple versions of the purchasing power parity doctrine ppp that doctrine in its absolute version states that the equilibrium exchange rate between domestic and foreign currencies equals the ratio of domestic to foreign price levels the relative version of the doctrine relates equilibrium changes in exchange rates to changes in the ratio of domestic to foreign prices during the 1970 s short run changes in exchange rates bore little relationship to short run differentials in national inflation rates and frequently divergences from purchasing power parities have been cumulative this paper reviews and analyzes the empirical record of exchange rates and prices during the 1970 s and the analysis is based on the experience of the dollar pound the dollar frecch franc and the dollar dm exchange rates section 2 presents the evidence on ppp during the 1970 s and contrasts it with the evidence from the 1920 s a period during which the doctrine held up reasonably well this analysis is relevant for assessing whether the flexible exchange rate system was successful in providing national economies with an added degree of insulation from foreign shocks and whether it provided policymakers with an added instrument for the conduct of macroeconomic policy the evidence regarding devia tions from purchasing power parities is also relevant for determining whether there is a case for managed float section 3 attempts to explain what went wrong with

welfare analysis of tax reforms using household data abstract this paper discusses a methodology for calculating the distribution of gains and losses from a policy change using data for a large sample of households estimates are based on the equivalent income function which is money metric utility defined over observable variables this enables calculations to be standardised and a computer program to compute the statistics presented in the paper is available for a general demand system equivalent income is related to measures of deadweight loss and standard errors are computed for each of the welfare measures an application to u k data for 5 895 households is given which simulates a reform that involves eliminating housing subsidies

an index of inequality with applications to horizontal equity and social mobility horizontal equity and social mobility are discussed in terms of a non utilitarian social welfare function which takes account of the process by which an ex ante distribution is mapped into an ex post distribution by the tax system for example an index of inequality is proposed which decomposes into two components corresponding to vertical and horizontal equity respectively a functional form for the social welfare function is derived for the purposes of empirical work and an application to data for 5895 uk households is presented the paper contains a theoretical application of the index to a model of optimal taxation it is conventional to assess the merits of alternative public policies in terms of a trade off between equity and efficiency in practice however a change in say the tax system involves three effects first it may have incentive or disincentive effects leading to efficiency gains or losses secondly it may alter the distribution of welfare levels thirdly it may alter the ranking of individuals or households within the distribution these three effects correspond to efficiency vertical equity and we shall argue certain aspects of horizontal equity respectively and any assessment of a tax change must take into account all three the principal assumption of this paper is that government is concerned about the trade off between these three effects a strict utilitarian is concerned only with the consequences of an action and in the evaluation of a particular reform a utilitarian measure of social welfare is defined over the vector of ex post utilities no account is taken of the process by which the vector of ex ante utilities is mapped into the ex post vector and no ethical status is awarded to the ex ante distribution one does not have to adopt an entitlement theory of justice to believe that the utilitarian approach may ignore some relevant considerations such as the fairness of the redistributive process a striking example of this arises in the model used by mirrlees 11 to examine optimal income taxation in that model individuals have identical preferences defined over consumption and leisure and differ only in respect of their potential wage rates or ability levels clearly in the absence of taxation individual utility is an increasing function of ability suppose the government uses redistributive lump sum taxes to achieve the first best optimum then as mirrlees 11 12 shows the first best optimum for a utilitarian social welfare

exchange rate volatility and exports new empirical evidence from the emerging east asian economies this paper examines the impact of bilateral real exchange rate volatility on real exports of five emerging east asian countries among themselves as well as to 13 industrialised countries we recognise the specificity of the exports between the emerging east asian and industrialised countries and employ a generalised gravity model in the empirical analysis we use a panel comprising 25 years of quarterly data and perform unit root and cointegration tests to verify the long run relationship among the variables the results provide strong evidence that exchange rate volatility has a negative impact on the exports of emerging east asian countries in addition the results suggest that the pattern of bilateral exports is influenced by third country variables an increase in the price competitiveness of other emerging east asian countries has a negative impact on a country s exports to a destination market but the magnitude of the impact is relatively small these results are robust across different estimation techniques and do not depend on the variable chosen to proxy exchange rate uncertainty the results of the gmm iv estimation also confirm the negative impact of exchange rate volatility on exports and suggest that this negative relationship is not driven by simultaneous causality bias

time varying yield curve dynamics and monetary policy monetary policy the yield curve and the private sector behaviour of the us economy are modelled as a time varying structural vector autoregression the monetary policy shocks of the early 1980s explain a large portion of the persistence of inflation and the level of the term structure changes in inflation expectations implied by the yield curve account for the persistence of the federal funds rate failures of the expectations hypothesis are rare and coincided with the credibility building of paul volcker s fed tenure at the beginning of the 1980s and the sequence of consecutive policy rate cuts around the time of the early 1990s recession copyright 2009 john wiley sons ltd

exchange rate volatility and international trade a general equilibrium analysis abstract we analyze the relation between exchange rate volatility and the volume of international trade in a general equilibrium stochastic endowment economy with imperfect international commodity markets and treating both variables as endogenous even in the simplest model the sign of the relation depends on the source for the change in volatility for instance more volatility of the endowments and higher costs to international trade both boost exchange risk and lower welfare but the first increases the expected volume of trade while the second decreases trade note that even the inter equilibria relation between trade and welfare is ambiguous

a measure of horizontal inequity politicians academicians and the general public alike have perceived that the status quo tax and transfer legislation creates inequities among living units tax laws create numerous situations in which living units with seemingly equal abilities to pay are taxed quite different amounts state by state differences in welfare eligibility rules benefit schedules and administrative procedures the general unavailability of cash welfare to childless nonaged healthy couples and single individuals and other features of transfer programs similarly provide vastly different levels of income support to units with equal needs advocates of major tax and welfare reform have marshalled such evidence into a central argument in favor of their proposals while there is wide agreement that the process of redistributing incomes abounds with inequities there have been few attempts to quantify their extent 2 this paper develops a measure of horizontal inequity and illustrates its use section ii discusses the concept of horizontal equity then builds upon familiar lorenz curve gini coefficient analysis to derive the inequity index the third part considers some problems of implementing the measure and illustrates it section iv provides a short conclusion

progressivity horizontal equity and reranking in health care finance a decomposition analysis for the netherlands this paper employs the method of aronson et al 1994 to decompose the redistributive effect of the dutch health care financing system into three components a progressivity component a classical horizontal equity component and a reranking component results are presented for the health care financing system as a whole as well as for its constituent parts a final section sets out to uncover the relative importance in terms of their effects on progressivity horizontal equity and reranking of the key institutional features of one component of the dutch system the awbz social insurance scheme

exchange rate volatility exchange rate regime and trade volume evidence from the uk us export function 1889 1999 abstract this paper investigated the impact of exchange rate volatility and exchange rate regime on the british exports to the united states using data for the period 1889 1999 the empirical findings suggest that neither exchange rate volatility nor the different exchange rate regimes that spanned the last century had an effect on export volume

the social cost of living index abstract household cost of living indexes reflect household preferences analogous indexes for groups of households require a corresponding concept of group preferences in this paper i investigate the social cost of living index a group index based on the bergson samuelson social welfare function i first define the index and examine its properties under the assumption that the investigator constructing it expresses his distributional judgments in an explicit bergson samuelson social welfare function i then examine the maximizing society and the independent society two cases in which the index can be constructed from the information contained in the market demand functions in these two cases a laspeyres index i e the fixed weight index based on the reference consumption pattern is an upper bound on the exact social cost of living index in general however the assumptions required to place bounds on the social cost of living index are much more likely to be satisfied than those required to place analogous bounds on a household s cost of living index

the central bank as shaper and observer of events the case of the yield spread the yield spread has commonly been employed as a successful predictor of economic growth and recessions although its marginal predictive power has decreased since the 1990s notably the yield spread s declining power to predict us economic activity coincided with its growing power to predict us interest rate changes in my view these phenomena are inevitably linked and share one cause the central bank intended to enhance both its transparency and credibility through greater information disclosure this disclosure improved interest rate predictability but might also have crowded out useful private information formerly in the yield spread that helped predict economic activity

a time varying parameter structural model of the uk economy abstract we estimate a time varying parameter structural macroeconomic model of the uk economy using a bayesian local likelihood methodology this enables us to estimate a large open economy dsge model over a sample that comprises several different monetary policy regimes and an incomplete set of data our estimation identifies a gradual shift to a monetary policy regime characterised by an increased responsiveness of policy towards inflation alongside a decrease in the inflation trend down to the two percent target level the time varying model also performs remarkably well in forecasting and delivers statistically significant accuracy improvements for most variables and horizons for both point and density forecasts compared to the standard fixed parameter version

exchange rate effects on the volume and variability of trade flows abstract this paper investigates the effects of exchange rate uncertainty on the volume and variability of trade flows employing a signal extraction framework we show that the direction and magnitude of importers and exporters optimal trading activities depend upon the source of the uncertainty general microstructure shocks fundamental factors driving the exchange rate process or a noisy signal of policy innovations providing a rationale for the contradictory empirical evidence in the literature we also show that exchange rate uncertainty emanating from general microstructure shocks and the fundamental factors reduces the variability of trade flows while that related to a noisy signal of policy innovations increases variability

does the exchange rate follow a random walk a monte carlo study of four tests for a random walk abstract several authors have urged that real and nominal exchange rates follow a random walk conditions under which the exchange rate follows a random walk are reviewed in this paper many of these do not appear to hold therefore the empirical evidence presents a puzzle some evidence suggets the exchange rate follows a random walk while other evidence suggests the opposite should be true this paper attempts to reconcile the evidence it is argued that the tests for a random walk have low power monte carlo evidence on four tests for a random walk is presented that suppors this claim

does real exchange rate volatility affect sectoral trade flows this article investigates empirically the effect of real exchange rate volatility on sectoral bilateral trade flows between the united states and its top 13 trading partners our investigation also considers those effects on trade flows that may arise through changes in income volatility and the interaction between income and exchange rate volatilities we provide evidence that i exchange rate volatility does not systematically affect sectoral trade flows ii income volatility has little impact on trade flows and iii the effect of the interaction term on trade flows is opposite that of exchange rate volatility dampening its impact on trade flows

on some international parity conditions an empirical investigation abstract this paper investigates weak semi strong and strong forms of the following international parity conditions a uncovered interest parity b the hypothesis of equal ex ante real interest rates and c ex ante purchasing power parity the main results are as follows using data which roughly cover the 1975 1984 decade we find little evidence in favor of the strong form of the parity conditions under consideration however most test results are consistent with the weak forms finally regarding the semi strong forms the results are mixed

growth and exchange rate volatility a panel data analysis the aim of this article is to assess the role of real exchange rate rer volatility on long run economic growth for a set of 82 advanced and emerging economies using a panel data set ranging from 1970 to 2009 with an accurate measure for exchange rate volatility the results for the two step system generalized method of moments gmm panel growth models show that a more less volatile rer has a significant negative positive impact on economic growth the results are also robust for different model specifications

monetary policy shifts and long term interest rates the pure expectations hypothesis peh serves as the benchmark model for the relationship between yields on bonds of different maturities when coupled with rational expectations however empirical renderings of the model fail miserably i explore the possibility that failure to account for changes in monetary policy regime explains much of the failure of the peh estimating changing monetary regimes in conjunction with the peh significantly improves its performance the predicted spread between the long and short rates is highly correlated with the actual spread the standard deviation of the theoretical spread is nearly identical to that of the actual spread

the persistence of inflation in the united states abstract has the persistence of inflation in the united states changed since 1965 we estimate the persistence of inflation over time using different measures and estimation procedures and we produce confidence intervals for our estimates as well as formal tests of unchanged persistence we find that inflation persistence has been high and approximately unchanged in the u s over our sample period we reconcile our results with other studies that reached different conclusions

going multinational under exchange rate uncertainty abstract we analyze a model where an exporting firm competes a la cournot in a foreign market the firm faces exchange rate uncertainty and has the option to invest abroad the paper contributes four results first real option pricing techniques are used to derive the optimal timing rule of the investment and the price of the firm and foreign competitors second the sunk cost of entry into the foreign market introduces hysteresis in direct investment flows we find that the degree of hysteresis grows with the number of firms in the industry third we determine the conditions under which dumping may appear and the role of fdi in precluding this type of dumping fourth tariffs have the well known fdi inducing effect more so in less competitive markets and are more effective at deterring delocation furthermore a tariff might have the effect of triggering dumping

new keynesian economics and the phillips curve models with sticky prices are an important part of new keynesian economics the author shows that several of the new keynesian models imply a formulation that is similar to the expectations augmented phillips curve of milton friedman and edmund phelps he then presents new estimates of the new keynesian phillips curve the author uses two proxies for price expectations survey based measures and an econometric based measure originally developed by bennett mccallum 1976 overall the results are consistent with the model but the survey based results are more precise suggesting that the surveys may be better measures of actual expectations copyright 1995 by ohio state university press

the measurement of horizontal inequality an alternative approach to the measurement of horizontal inequality is developed this measure of inequality is based on an explicit social welfare function which is formulated so as to be consistent with the basic principles of social choice the arguments of the social welfare function are welfare functions that depend on prices total expenditure and the demographic composition of the household the level of horizontal inequality is defined to be the difference between the level of social welfare attained at a perfect horizontally egalitarian distribution of welfare and the level of social welfare attained at the existing distribution of individual welfare the level of horizontal inequality induced by the introduction of commodity taxes is evaluated for the united states over the period 1947 85 copyright 1989 by mit press

the impact of exchange rate volatility on brazilian manufactured exports the purpose of this paper is to examine the relation between exchange rate volatility and the volume of exports using brazilian data after establishing the existence of cointegration among the variables included in our model we estimated the long run coefficients by means of an auto regressive distributed lag ardl model our results show that exchange rate volatility had a significantly negative effect on brazilian manufactured exports in the period 1986 2002

exchange rate shocks and trade a multivariate garch m approach abstract we build on the recent literature studying the effects of uncertainty on trade by introducing a model that combines a reduced form vector autoregression for the growth rates of exports foreign income and the real exchange rate rer with a multivariate garch model up to 12 lags of several conditional standard deviations are added to relevant mean equations and all parameters are estimated simultaneously using maximum likelihood thus allowing us to avoid two step procedures that are common in the literature using a large data set of both developed and emerging countries we find evidence that rer uncertainty negatively impacts trade for several less developed countries we also find that rer uncertainty tends to be associated with a real currency appreciation when we compute generalized impulse response functions to study the impacts of unexpected shocks to rer growth on export growth the results are typically asymmetric positive shocks generate substantial negative responses while unexpected depreciations produce relatively smaller positive responses especially in our developing country sample

shifting endpoints in the term structure of interest rates abstract this paper links the term structure to perceptions of monetary policy long horizon forecasts of short rates required by no arbitrage term structure models are heavily influenced by the endpoints or limiting conditional forecasts of the short rate process common assumptions that the short rate is mean reverting or contains a unit root are shown to generate unrealistic yield predictions failures occur because these assumptions inadequately account for historical shifts in market perceptions of the policy target for inflation this paper links endpoint shifts to agent learning about shifts in long term policy goals shifting endpoints in short rate processes significantly improve yield predictions

term structure evidence on interest rate smoothing and monetary policy inertia abstract numerous studies have used quarterly data to estimate monetary policy rules or reaction functions that appear to exhibit a very slow partial adjustment of the policy interest rate the conventional wisdom asserts that this gradual adjustment reflects a policy inertia or interest rate smoothing behavior by central banks however such quarterly monetary policy inertia would imply a large amount of forecastable variation in interest rates at horizons of more than 3 months which is contradicted by evidence from the term structure of interest rates the illusion of monetary policy inertia evident in the estimated policy rules likely reflects the persistent shocks that central banks face

does the fed act gradually a var analysis abstract the tendency for changes in the federal funds rate to be implemented gradually has been considered evidence of an interest rate smoothing objective for the federal reserve this paper investigates whether gradual funds rate movements can be explained by the dynamic structure of the economy and the uncertainty surrounding that structure without recourse to including an ad hoc interest rate smoothing argument in the fed s objective function in the absence of parameter uncertainty the optimal policy involves more aggressive movements in the funds rate than observed parameter uncertainty however limits the responsiveness of the interest rate as a result the optimal policy under parameter uncertainty can account for a considerable portion of the gradualism observed

exchange rate volatility international trade and the value of exporting firms abstract increased exchange rate volatility positively affects the value of exporting firms via the price and volume impacts of exchange rates and also makes an exporting strategy more attractive relative to the direct investment investment in export production capacity could therefore be a positive function of exchange rate volatility firms would also be more willing to sustain losses i e to engage in dumping before they abandon their export markets the effect on the volume and value of trade is ambiguous

changing macroeconomic dynamics at the zero lower bound this article develops a change point var model that isolates four major macroeconomic regimes in the us since the 1960s the model identifies shocks to demand supply monetary policy and spread yield using restrictions from a general equilibrium model the analysis discloses important changes to the statistical properties of key macroeconomic variables and their responses to the identified shocks during the crisis period spread shocks became more important for movements in unemployment and inflation a counterfactual exercise evaluates the importance of lower bond yield spread during the crises and suggests that the fed s large scale asset purchases helped lower the unemployment rate by about 0 6 percentage points while boosting inflation by about 1 percentage point

exchange rate volatility and intra asia trade evidence by type of goods this paper examines the impact of intra asia exchange rate volatility on intra asia trade in primary goods intermediate goods equipment goods and consumption goods from 1980 to 2009 for asia the evidence shows that as intraregional exchange rate volatility increases intraregional exports in these goods fall this adverse impact is even more pronounced in the subregion of association of southeast asian nations asean 5 comprising asean member countries plus the people s republic of china hong kong china japan the republic of korea and taipei china and especially among intermediate and equipment exports again the impact magnifies in an even smaller subgroup excluding the smaller asean economies these results underline the significant impact of exchange rate volatility on the region s production networks for south asia however exchange rate volatility appears to have a positive impact on exports still caution is warranted given that south asian economies trade relatively little with each other

the yield curve and the macro economy across time and frequencies this paper assesses the relation between the yield curve and the main macroeconomic variables in the u s between early 1960s and 2009 across time and frequencies using wavelet analyses the shape of the yield curve is modelled by latent factors corresponding to its level slope and curvature estimated by maximum likelihood with the kalman filter the macroeconomic variables measure economic activity unemployment inflation and the fed funds rate the cross wavelet tools employed coherency and phase difference the set of variables and the length of the sample allow for a thorough appraisal of the timevariation and structural breaks in the direction intensity synchronization and periodicity of the relation between the yield curve and the macro economy our evidence establishes a number of new stylized facts on the yield curve macro relation and sheds light on several results found in the literature which could not have been achieved with analyses conducted strictly in the time domain as most of the literature or purely in the frequency domain

exchange rate variability and the export demand for malaysia s semiconductors an empirical study this article examines the effects of exchange rate variability on export demand for semiconductors which is the largest sub sector of electronics industry in malaysia as reported by malaysian industrial development authority mida 2004 the empirical results which are estimated based on the johansen s multivariate cointegration tests and error correction model suggest that there is a unique long run relationship among quantities of export relative price real foreign income and real exchange rate variability the major finding of this article is that the variability of real exchange rate has some effect on semiconductor exports in both the long run and the short run in the light of rapid advances in technology in the global markets for electronics products the findings are useful to policy makers for the design and target of appropriate exchange rate and industrial policies to enhance the export competitiveness of semiconductor industry

volatility transmission between stock and foreign exchange markets a connectedness analysis abstractthis paper empirically investigates volatility transmission among stock and foreign exchange markets in seven major world economies during the period july 1988 to may 2018 to this end we

the incredible volcker disinflation abstract the reduction in inflation that occurred in the early 1980s when the federal reserve was headed by paul volcker is arguably the most widely discussed and visible macroeconomic event of the last 50 years of u s history inflation had been dramatically rising but under volcker the fed first contained and then reversed this process using a simple modern macroeconomic model we argue that the real effects of the volcker disinflation were mainly due to its imperfect credibility in our view the observed upward volatility and subsequent stubborn elevation of long term interest rates during the disinflation are key indicators of that imperfect credibility studying transcripts of the federal open market committee recently released to the public we find to our surprise that volcker and other fomc members likewise regarded the long term interest rates as indicative of inflation expectations and of the credibility of their disinflationary policy drawing from the transcripts and other contemporary sources we consider the interplay of monetary targets operating procedures and credibility during the volcker disinflation

time to build option value and investment decisions abstract investment decisions and outlays are often made sequentially for example the rate at which construction proceeds is usually flexible and can be adjusted with the arrival of new information traditional discounted cash flow methods which treat the pattern of investment as fixed ignore this flexibility and understate the value of the project this paper uses contingent claims analysis to derive optimal decision rules and to value such investments we determine the effects of time to build opportunity cost and uncertainty on the investment decision for reasonable parameter values we show how a simple npv rule can lead to gross errors

the impact of the post 1972 floating exchange rate regime on us exports by employing the techniques of cointegration and error correction models this article empirically investigates the impact of the post 1972 floating exchange rate regime on the volume of us bilateral exports to canada germany japan and the uk the econometric models specified in the analysis were estimated using quarterly data for the sample period 1959 1 1997 4 the empirical results provide evidence that the post 1972 exchange rate regime is less conducive to trade than the bretton woods fixed exchange rate regime

exchange risk exposure and the option to trade rather than impeding trade increased exchange rate uncertainty may on average create trade as it implies a higher probability that ex post deviations from commodity price parity will exceed tariffs and transportation costs we demonstrate such an effect in a small country short term model under the alternative assumptions of perfect competition and of a monopolist trader producer the proofs rely on the fact that such firms exposures can be replicated and hedged by standard options under partial monopoly scenarios the effect of volatility is ex ante unclear though jel f31
