the pricing of currency risk in japan abstract previous work on the pricing of exchange rate risk has primarily focused on us firms and surprisingly found stock returns were not significantly affected by exchange rate fluctuations in this paper we conduct an in depth investigation that examines whether exchange rate risk is priced in the equity market of japan using an intertemporal asset pricing testing procedure that allows risk premia to change through time in response to changes in macroeconomic conditions our multiperiod asset pricing tests show that the foreign exchange rate risk premium is a significant component of japanese stock returns specifically the results suggest that currency risk exposure commands a significant risk premium for multinationals and high exporting japanese firms the currency risk factor is found to be less influential in explaining the behavior of average returns for low exporting and domestic firms however it is shown to exhibit large return volatility that is likely to be perceived by investors who wish to control portfolio risk as an important underlying source of risk furthermore japanese stock returns are found to be related to the relative distress and size factors above and beyond the covariation explained by the currency risk factor

14 week quarters many firms define their fiscal quarters as 13 week periods for these firms each fiscal year contains 52 weeks which leaves out one two day s a year to compensate one extra week is added to every fifth sixth year consequently one quarter therein comprises 14 weeks we find evidence of predictable stock returns and forecast errors in 14 week quarters which suggests that investors and analysts do not on average adjust their expectations for the extra week the ease with which 14 week quarters can be predicted and expectations adjusted suggests a surprising lack of effort on the part of investors and analysts

dynamic linkages among equity markets local versus basket currencies this article compares the stability of interrelationships among nine national equity markets by employing basket currencies versus individual base currencies to measure rates of return we show that the average correlations of equity indexes based on basket currencies are much lower than the average correlations of equity indexes based on individual home base currencies additionally empirical directed graph results from using basket currencies are more consistent with each other than the results from using different individual currencies we conclude that basket currencies provide more robust results for studying equity market comovements than individual currencies by implication studies on equity market interrelationships including studies on potential financial contagion between equity markets should use basket currencies to avoid currency dependent results

nonmonetary effects of the financial crisis in propagation of the great depression this paper examines the effects of the financial crisis of the 1930s onthe path of aggregate output during that period our approach is complementary to that of friedman and schwartz who emphasized the monetary impact of the bank failures we focus on non monetary primarily credit related aspects of the financial sector output link and consider the problems of debtors as well as those of the banking system we argue that the financial disruptions of 1930 33 reduced the efficiency of the credit allocation process and that the resulting higher cost and reduced availability of credit acted to depress aggregate demand evidence suggests that effects of this type can help explain the unusual length and depth of the great depression this abstract was borrowed from another version of this item

international evidence on the determinants of foreign exchange rate exposure of multinational corporations in this paper we explore some of the potential determinants of foreign exchange fx exposure and firm value we contribute to previous research on stock returns and firm value as we have access to a unique survey database and can include as determinants in our empirical analysis the objectives and emphasis on risk management as well as considering previous factors including the nature of the business environment we can also examine any regional influences as our sample includes uk us and asia pacific multinational companies mncs as predicted by theory we find some evidence that mncs with greater foreign operations have a larger magnitude of fx exposure however our proxy for the emphasis of fx management does not have the predicted negative association with the magnitude of fx indicating that managers may focus on short term cash flows in their fx management rather than firm value with regard to the potentially differential regional role of our variables a range of interesting results is found arguably in our most notable such finding we see that the contribution of overseas business to total revenues has no association with the magnitude of fx exposure for us mncs it has a positive role for uk mncs consistent with theory and a negative role for asia pacific mncs which could be explained by macroeconomic and or financial characteristics of the mncs in the sample

how do u s stock returns respond differently to oil price shocks pre crisis within the financial crisis and post crisis abstract we use a long time series of daily data for 682 firms over a period from january 1990 to december 2012 each firm includes 5 772 daily observations our sample involves a total of 3 936 504 observations to investigate how u s stock returns respond differently to oil price shocks prior to during and after a financial crisis we provide evidence that u s stock returns in turn respond positively to the changes in oil prices during and after such a crisis we use firm level data to find that positive and negative oil price shocks have asymmetric effects on stock returns during the crisis and after the crisis then we examine whether the effect of an oil price shock on stock returns varies across oil intensive industries within the crisis and post crisis our results indicate that stock returns in response to oil price shocks across industries are heterogeneous and the stock returns of some energy intensive manufacturing industries respond more positively to oil price shocks compared with less energy intensive manufacturing industries we use total assets total revenue and the number of employees as proxy variables to measure each firm s size and then examine whether oil price shocks affect stock returns differently across firm sizes we find that big firms are the most strongly and negatively influenced by an oil price shock prior to the crisis on the other hand our results indicate that an oil price shock in the post financial crisis period is positively amplified in the case of medium sized firms

firm valuation earnings expectations and the exchange rate exposure effect consistent with previous research we fail to find a significant correlation between the abnormal returns of our sample firms with international activities and changes in the dollar we investigate the possibility that this failure is due to mispricing lagged changes in the dollar are a significant variable in explaining current abnormal returns of our sample firms suggesting that mispricing does occur a simple trading strategy based upon these results generates significant abnormal returns corroborating evidence from returns around earnings announcements as well as errors in analysts forecasts of earnings is also provided it is a widely held view that exchange rate movement should affect the value of a firm standard economic analysis implies that the profitability and value of most u s firms with foreign sales or operations abroad should increase decrease with an unexpected depreciation appreciation of the dollar as expected foreign currency cash flows translate into larger smaller u s

crossing the lines the conditional relation between exchange rate exposure and stock returns in emerging and developed markets this paper examines the importance of exchange rate exposure in the return generating process for a large sample of non financial firms from 37 countries we argue that the effect of exchange rate exposure on stock returns is conditional and show evidence of a significant return impact to firm level currency exposures when conditioning on the exchange rate change we further show that the realized return to exposure is directly related to the size and sign of the exchange rate change suggesting fluctuations in exchange rates as a source of time variation in currency return premia for the entire sample the return impact ranges from 1 2 to 3 3 per unit of currency exposure and it is larger for firms in emerging markets compared to developed markets overall the results indicate that foreign exchange rate exposure estimates are economically meaningful despite the fact that individual time series results are noisy and many exposures are not statistically significant and that exchange rate exposure plays an important role in generating cross sectional return variation moreover we show that the relation between exchange rate exposure and stock returns is more consistent with a cash flow effect than a discount rate effect

precautionary saving over the business cycle we study the macroeconomic implications of time varying precautionary savings within a general equilibrium model with borrowing constraints aggregate shocks and uninsurable idiosyncratic unemployment risk our framework generates limited cross sectional household heterogeneity as an equilibrium outcome thereby making it possible to analyse the role of precautionary saving over the business cycle in an analytically tractable way the time series behaviour of aggregate consumption generated by our model is closer to the data than that implied by the hand to mouth and representative agent models and it is comparable to that produced by the krusell and smith 1998 model

asymmetric exchange rate exposure theory and evidence abstract this paper tests the hypothesis that exchange rate exposure is asymmetric over appreciation depreciation cycles more specifically it investigates whether returns on nine sector indexes across four major countries are asymmetrically affected by exchange rate movements the results show that in several instances exposure is asymmetric asymmetries are found to be more pronounced in the financial and non cyclical sectors possible theoretical explanations are provided regarding the particular type of exposure found across sectors and countries

a joint test of market segmentation and exchange risk factor in international capital market market segmentation and exchange risk are two main factors that distinguish international financing and investment decisions from domestic ones existing studies of market segmentation have been conducted within a framework in which exchange risk is not explicitly recognized this paper performs a joint test of market segmentation and exchange risk pricing based on individual stock data from seven major countries outside of the u s for the period january 1981 to december 1989 the theoretical framework used is a multifactor model with domestic and world market factors and an exchange risk factor the maximum likelihood method is used to estimate risk premia and factor analysis is used to provide additional evidence on the pricing of risk factors the results indicate that a the factor structure of asset returns is internationally heterogeneous b many national capital markets can be described as partially segmented rather than the polar cases of complete segmentation or integration and c exchange risk is a significant factor affecting asset returns in addition to the domestic and world market risk factors

exchange rates and cash flows in differentiated product industries a simulation approach how do exchange rate changes impact firms cash flows we extend a simulation method developed in industrial organization to answer this question we use prices quantities and product characteristics for differentiated products coupled with a discrete choice framework and an assumption of price competition to estimate marginal costs for all producers using a monte carlo approach we generate counterfactual prices and profits for different levels of exchange rates we illustrate the method using the market for bottled water our results stress that even in a relatively simple market such as this one different brands face very different exchange rate risks consider a firm that produces a good in france using mainly local inputs and sells it abroad in locations that have a floating exchange rate vis a vis the euro profits and in turn the value of the firm are potentially exposed to exchange rate changes if the euro appreciates profits when measured in euros are likely to decrease how large is the decrease in profits similarly what is the impact of such an exchange rate change on the profits of an import competing firm these are the questions that a large literature on exchange rate exposure attempts to answer

testing the stochastic structure of production a flexible moment based approach conventional production function specifications are shown to impose restrictions on the probability distribution of output that cannot be tested with the conventional models these restrictions have important implications for firm behavior under uncertainty a flexible representation of a firm s stochastic technology is developed based on the moments of the probability distribution of output these moments are a unique representation of the technology and are functions of inputs large sample estimators are developed for a linear moment model that is sufficiently flexible to test the restrictions implied by conventional production function specifications the flexible moment based approach is applied to milk production data the first three moments of output are statistically significant functions of inputs the cross moment restrictions implied by conventional models are rejected

avoiding default the role of credit in the consumption collapse of 1930 high consumer indebtedness threatens future consumption spending if default is expensive consumer spending collapsed in 1930 turning a minor recession into the great depression households were shouldering an unprecedented burden of installment debt down payments were large contracts were short equity in durable goods was therefore acquired quickly missed installment payments triggered repossession reducing consumer wealth in 1930 because households lost all acquired equity cutting consumption was the only viable strategy in 1930 for avoiding default institutional changes lowered the cost of default by 1938 when recession began again indebted households chose to default rather than reduce consumption

endogenous markups and the effects of income taxation theory and evidence from oecd countries abstract existing studies on the effects of fiscal policy under imperfect competition typically treat each firm s price cost markup as fixed this paper examines the implications of endogenising the markup in a simple model of income taxation under monopolistic competition it is demonstrated that an increase in income tax reduces the number of firms lessens competition among surviving firms and raises the optimal markups in the new steady state through this channel the effects of income taxation on the key macroeconomic variables as well as on consumer welfare are unambiguously enlarged the simple model prediction is largely supported by cross section regressions with data from oecd countries

linear and nonlinear foreign exchange rate exposures of german nonfinancial corporations this paper investigates whether the low significance of the impact of foreign exchange rate risk on firm value reported in previous studies can be explained by the fact that only the linear exposure component has been estimated or that exchange rate indices were used for a comprehensive sample of german firms empirical evidence is presented for the existence of significant linear and nonlinear exposures which can be identified for bilateral as well as multilateral foreign exchange rates the percentage of foreign sales measures of firm liquidity and industry sectors are significant determinants of the exposure

international competition and exchange rate shocks a cross country industry analysis of stock returns this article systematically examines the importance of exchange rate movements and industry competition for stock returns common shocks to industries across countries are more important than competitive shocks due to changes in exchange rates weekly exchange rate shocks explain almost nothing of the relative performance of industries using returns measured over longer horizons the importance of exchange rate shocks increases slightly and the importance of industry common shocks increases more substantially both industry and exchange rate shocks are more important for industries that produce internationally traded goods but the importance of these shocks is economically small for these industries as well economists journalists and politicians around the world argue that some of the industries in their country compete vigorously with the same industries in other countries and that exchange rate shocks affect their competitiveness in the united states it is routinely stated that some u s industries compete with japanese industries and that a depreciation of the yen is bad for these u s industries and good for the rival japanese industries if the yen falls trade tensions could intensify between the u s and japan as autos and machinery from japan gain a competitive edge 1 further the exchange rate literature shows that exchange rate shocks lead to persistent deviations from purchasing power parity 2 froot and klemperer 1989 and knetter 1989 1993 among others demonstrate that deviations from purchasing power parity lead to sharp changes in price markups and profit margins for exporters

exchange rates and firms liquidity evidence from adrs abstract exchange rate changes can in principle affect a firm s value by affecting the firm s earnings or its cost of funds existing studies using monthly data over long sample periods find little or no impact of changes in exchange rates on a firm s valuation we examine a different potential path for exchange rate effects namely the effect of exchange rate variability on a stock s liquidity using transactions data we examine the microstructure characteristics of united kingdom and mexican american depositary receipts adrs around two major exchange rate crises the pound sterling withdrawal from the european exchange rate mechanism in september 1992 and the mexican devaluation of december 1994 we conclude that these events of exchange rate turbulence had little or no effect on the trading costs of adrs in the united states the results suggest that the impact of exchange rate volatility on market liquidity is not a conduit by which stock values are affected

firm level effects of asymmetric intervention in foreign exchange markets evidence from the swiss currency floor in january 2015 the swiss national bank snb abandoned the swiss franc s exchange rate floor against the euro this paper is the first to study the firm level effects of this asymmetric type of central bank intervention in foreign exchange markets using weekly stock returns for a sample of swiss non financial firms i find significant reductions in total stock return volatility as well as market risk following the introduction of the currency floor accounting for the asymmetric nature of the intervention i show that the enforcement of this policy solely manifests in a significant reduction of incremental eur chf exchange rate risk exposures of exporting firms while importing firms experience reductions in proportion to the market portfolio only thus the asymmetric policy design is reflected in asymmetric responses of firm level currency exposures all effects however do not depend on the extent of business activity in the eurozone the overall results suggest that the currency floor was successful in supporting the performance of the swiss economy by effectively reducing stock return sensitivities to market fluctuations and eur chf exchange rate volatility

income uncertainty and the onset of the great depression income uncertainty and the onset of the great depression income uncertainty contributes substantially to explaining the fall in consumption that marks the onset of the great depression consistent estimates of the variance of income measure income uncertainty from 1921 30 and are produced using a linear moment model this series provides a statistical link between the large erratic swings in income uncertainty after september 1929 and the great crash in the stock market comparison of the behavior of income uncertainty in the 1920s to the pre world war i and post world war ii eras suggests that the experience after the great crash was historically unique i introduction the great depression of 1929 41 can be broken down into several phases i the initial recessionary phase from october 1929 to october 1930 ii the first two waves of bank failures between november 1930 and december 1931 iii the incipient recovery of late 1932 and the impending collapse in march 1933 iv the recovery of the financial system and the economy from the cyclical trough and v the recession of 1937 38 among others many researchers have presented well articulated theories and extensive empirical analyses for each phase of the depression friedman and schwartz 1963 hamilton 1987 gordon and wilcox 1981 and burbidge and harrison 1985 have examined the role of money and monetary policy during the depression brown 1956 examined the stance of fiscal policy during this period bernanke 1983b provided an explanation of the role of the financial crisis in the propagation of the great depression most of this research has focused on the events that turned a recession in 1929 30 that was not historically unprecedented that is it is comparable to the recession of 1920 22 into the deepest slide in the history of the american business cycle explanations of the depression s initial phase from late 1929 to october 1930 however are much less satisfactory meltzer 1976 and mishkin 1978 examined this period and concluded that the fall in output can be attributed largely to the stance of monetary policy and the stock market s impact on the household balance sheet respectively the remainder of the existing literature centers around a debate between temin 1976 1981 and schwartz 1981 that has produced no consensus about the role of monetary and nonmonetary factors in providing the impetus for the great depression hence the period sometimes called the mysterious first year 1 is the least understood of all the phases of the depression we think that recent advances in our understanding of the influence of income uncertainty on consumption expenditures may help explain the onset of the great depression the theoretical work of leland 1968 sandmo 1970 dreze and modigliani 1972 and others has shown that an increase in uncertainty about future income measured as the variance of income results in a reduction in current consumption expenditures under standard assumptions regarding risk preferences recently flacco and parker 1990 included an estimate of the standard deviation of income in a conventional specification of the consumption function from blinder and deaton 1985 and found that this measure of income uncertainty is indeed negatively related to consumption this result estimated using post world war ii data holds up to a number of statistical significance and specification tests romer 1990 examined the relationship between consumer expenditure proxied by various disaggregate spending series and stock market volatility during the first year and a half of the great depression expanding on bernanke s 1983a analysis of investment under uncertainty romer estimates a model of consumer spending on durable goods in the face of temporary uncertainty empirical evidence reveals that inclusion of the volatility of the stock market as a proxy for income uncertainty dramatically reduces forecast errors for consumption of durable goods in 1929 and 1930

some generalized mixture distributions with an application to unemployment duration compounding or mixture distributions provide a rich class of models for applications ranging from models of heterogeniety measurement error distribution of stock returns and income to models of unemployment duration some very general mixtures are considered which include many new mixture models and also provide a unified method of organizing and comparing previously considered models as well as a test of heterogeneity these models are used to analyze cps unemployment duration data a heterogeniety interpretation of the mixture models explains the discrepancy between implications of search theory and patterns observed in aggregate unemployment data copyright 1987 by mit press

training and the time to find a job in israel using high frequency data for israel it is found that trainees exit unemployment at a much faster rate than comparable unemployed who did not receive training it is argued that this powerful training effect is unlikely to be simply the result of positive self selection of trainees the training effect is detected when using nonparametric estimation methods parametric methods fail to pick it up because of a very large exit spike in the hazard function which occurs when the training is completed other findings include the following the duration of unemployment varies directly with the duration of entitlement to unemployment benefit as well as the replacement ratio also the exit hazard from unemployment rises as the benefit entitlement period draws to a close

are real exchange rates nonstationary evidence from a panel data test it is well documented that real exchange rates between the united states and many industrialized countries in the post bretton woods period are integrated this result implies that purchasing power parity ppp does not hold even as a long run relationship this paper demonstrates that the failure to reject the unit root hypothesis may result from the low power of existing univariate test procedures i test for unit roots in real exchange rates by employing a more powerful panel based procedure using both cpi and wpi real dollar exchange rate data i strongly reject the null hypothesis of a unit root my results provide overwhelming support for the long run ppp under the current float copyright 1996 by ohio state university press

conditioning the return generating process on firm specific events a discussion of event study methods empirical investigations into the codetermination of security prices and eco nomic events are called event studies there are several ways of estimating the codetermination of interest since fama fisher jensen and roll 8 it has been general practice to first translate variables into rates of return then net out gen eral market movements and finally examine the relationship between residual returns and events the methodology in all of its variants fails under the rubric of 4 residual analysis empirical methods used in residual analysis deviate from the structure and terminology generally found in classical econometrics while this is not a criticism of residual analysis it results in a communication problem that is more than simply pedantic in nature a broad body of econometric literature dealing with parameter estimation statistical inference and hypothesis testing often goes untapped by empiricists in finance who within internally consistent sets of as sumptions have created a separate body of statistical methods in this paper a union of the two disciplines is advocated to provide a forum for comparing and contrasting alternative empirical methods the event study problem is broken down into three phases the parameterization of informa tion arrival applicable to the problem an examination ofthe relationship between parameters in the information arrival process and the estimates resulting from alternative estimation methods and aggregation across firms experiencing simi

the joint response of stock and foreign exchange markets to macroeconomic surprises using us and japanese data abstract this paper investigates the joint response of stock and foreign exchange fx market returns to macroeconomic surprises employing a system method of estimation that allows for the cross country and cross market interaction for asset returns and risk premia using us and japanese data we find that us stock markets are asymmetrically responsive to domestic developments in output growth and interest rates but are not influenced by macroeconomic surprises from japan the surprise in the fx market seems to affect stock markets in the us and japan respectively in particular we find that the interest rate surprise in the us and inflation surprise in japan tend to overstate the impact that these surprises would have on the respective stock market the impact of the surprises would appear smaller if macroeconomic developments induced by the fx market were incorporated into the model

exchange rate exposure and industry characteristics evidence from canada japan and the usa abstract this paper examines industry level exchange rate exposures for canada japan and the usa measuring exposure by adding the change in the exchange rate to the domestic market model of industry portfolio returns some industries in all three countries display significant exposures moreover for each country the exchange rate is important for explaining industry returns at the economy wide level to explore whether exchange rate exposures are systematically linked to the activities of the industries we model exposure as a function of industry characteristics for all three countries the relation between exposure and industry characteristics is broadly consistent with economic theory jel f3

resolving the exposure puzzle the many facets of exchange rate exposure theory predicts sizeable exchange rate fx exposure for many firms however empirical research has not documented such exposures to examine this discrepancy we extend prior theoretical results to model a global firm s fx exposure and show empirically that firms pass through part of currency changes to customers and utilize both operational and financial hedges for a typical sample firm pass through and operational hedging each reduce exposure by 10 15 financial hedging with foreign debt and to a lesser extent fx derivatives decreases exposure by about 40 the combination of these factors reduces fx exposures to observed levels

a dynamic analysis of exchange rate exposure the impact of china s renminbi this study examines the impacts of unexpected exchange rate movements of chinese renminbi cny usd on stock returns of standard poor s 500 corporations to gain better insight into the long standing exposure puzzle concerning the divergence between theoretical and empirical investigation and the critical issue regarding the determinants of exposure the time variation and asymmetry property associated with foreign exchange exposure are further taking into account we also broaden the scope of analysis to investigate unexpected risk exposure at 10 economic sectors in compliance with global industry classification standard unlike those from the static analysis or dynamic ones with the ordinary least squares model the empirical findings provide additional concrete evidence that unexpected exchange rate exposure varies substantially across time and market circumstances when using the quantile regression with a rolling method furthermore our dynamic analysis not only supports the existence of industrial effects across different economic sectors but also provides strong evidence that financial factors such as size debt ratio and book to market ratio have a significant impact on exposure

dynamic linkages between asian stock prices and exchange rates new evidence from causality in quantiles this article applies the granger causality test in quantiles to investigate causal relations between stock returns and exchange rate changes for nine asian markets over the period 1 january 1997 to 16 august 2010 our empirical results indicate that the quantile causal relations vary across different quantiles and different periods although the causal effects of exchange rate changes on stock returns or stock returns on exchange rate changes are heterogeneous across quantiles the overall evidence suggests that most stock and foreign exchange markets are negatively correlated the result shows that there are more bidirectional causal relations in accordance with this method than the conventional least square ls estimation the symmetry of these quantile causal effects the averaging effect helps to explain why conventional ls method usually obtains an insignificant result of causality

corporate financial policies and performance around currency crises this paper studies firm level leverage and performance measures before and after a currency crisis using data from 17 countries we show that prior to a crisis companies that expect to benefit from currency depreciations increase their leverage more than companies that are expected to be harmed by the depreciation profitability and financial fragility ratios display consistent patterns we provide evidence that the asian crisis is different from the previous european and latin american ones in asia all firms become more fragile after the crisis and their profitability declines and leverage increases further whereas elsewhere there are clear signs of recovery after a crisis occurs

atheoretical macroeconometrics a critique abstract the spurious nature of the restrictions used to identify many macroeconometric models has led some researchers to advocate a style of econometric inquiry that is less dependent on prior theoretical restrictions of the sort that were central to the approach of the cowles commission this development which we call atheoretical macroeconometrics is summarized and evaluated in the current paper it is contrasted with an updated version of the cowles commission approach we conclude that while some of the exercises of atheoretical macroeconometrics are valid those that have attracted the most attention and appear the most innovative exogeneity testing impulse response analysis and policy analysis using estimated vector autoregressions are based on incorrect analysis

interest rate and exchange rate exposures of banking institutions in pre crisis korea this study empirically investigates interest rate and exchange rate exposures of banking institutions in pre crisis korea using the sensitivity of stock returns as a measure of the exposure it is shown that korean commercial banks and merchant banking corporations had been significantly exposed to both interest rate and exchange rate risks and that the subsequent profitability of commercial banks was significantly associated with the degree of pre crisis exposure the evidence suggests that along with the negative exposure of banking institutions the sharp depreciation of the korean won and high interest rates at the end of 1997 further deteriorated the banking sector s capital adequacy worsening the financial crisis the korean case highlights the importance of upgrading financial supervision and risk management practices as a precondition for successful financial liberalization

the foreign exchange exposure of japanese multinational corporations we find that about 25 percent of our sample of 171 japanese multinationals stock returns experienced economically significant positive exposure effects for the period january 1979 to december 1993 the extent to which a firm is exposed to exchange rate fluctuations can be explained by the level of its export ratio and by variables that are proxies for its hedging needs highly leveraged firms or firms with low liquidity tend to have smaller exposures foreign exposure is found to increase with firm size we also find that keiretsu multinationals are more exposed to exchange rate risk than nonkeiretsu firms it is conventional wisdom that exchange rate movements affect both the cash flows of a firm s operations and the discount rate employed to value these cash flows measuring foreign exchange exposure is now a central issue of international financial management and this issue has spawned a considerable amount of research existing empirical evidence on foreign exchange exposure however seems perplexing studies have so far documented a weak link between contemporaneous exchange rate fluctuations and stock returns of u s multinational firms 2 gendreau 1994 finds it difficult and unconvincing that the weak results imply that exchange rate changes have no effect on exporters stock returns bartov arnd bodnar 1994 attribute the observed insignificant relationship between exchange rate changes and st ock returns to probable problems associated with the previous studies samiple selection procedure or to mispricing caused by investors errors in estimat

foreign exchange exposure of us tourism related firms abstract to date literature on foreign exchange risk has paid a particular attention to multinationals in trade related industries the tourism sector is also sensitive to the exchange rates between travelers home countries and their destinations suspecting that the exposure of domestic tourism related firms to foreign exchange risk results from price elasticity of demand the current study tested the cash flow exposure of sample firms accounting for nonlinearity asymmetry and lagged effects as a result a significant percentage 78 of domestic tourism related firms was found to have significant foreign exchange exposure this study also found that exchange rate exposure for tourism related firms was nonlinear asymmetric and lagged the evidence implied that several tourism related firms are passive regarding their exposure and may face financial burdens caused by demand fluctuations implications and suggestions are presented along with the findings of the study

the dax and the dollar the economic exchange rate exposure of german corporations this paper examines the economic exposure of german corporations to changes in the dm us dollar exchange rate our work contributes to the existing body of literature in the following ways firstly we point out conceptual problems of previous attempts to estimate economic exposure secondly we find that german firms are significantly exposed to changes in the dm us dollar rate however our results are unstable over time

the effect of domestic uncertainty on the real options value of international investments scholars have noted that international investments have the potential to provide firms with real options value under uncertainty to assess this issue prior studies have tended to focus primarily on exchange rate volatility although multinational firms face other types of uncertainty as well including those stemming from their domestic operating environment the role of such uncertainty for firms flexibility needs has not been previously considered in this study we compare the influence of both domestic economic uncertainty and exchange rate uncertainty on the real option value of international investments of korean firms over 16 years of varying uncertainty we find evidence that an international investment network characterized by greater breadth and lower depth is associated with higher firm value under domestic economic uncertainty exchange rate uncertainty however was not found to play a role in firms need for flexibility the results suggest that firms are able to hedge exchange rate uncertainty by using mechanisms such as forward contracts or derivatives thus potentially reducing the impact of this type of uncertainty on their operations

an historical decomposition of the great depression to determine the role of money abstract the innovation accounting technique of historical decomposition seems ideally suited as a vehicle for a re examination of money s role during the depression its application using u s monthly data for 1919 to 1941 reveals that innovations in money exerted a considerable influence on prices and output after october 1929 although the depth of the depression and the extent of the subsequent recovery cannot be attributed solely to monetary factors an important albeit occasionally diminished monetary effect is also identified even when a passive contemporaneous response by money to price and output fluctuations is assumed not to contribute to the effect

anticipated money unanticipated money and output 1873 1930 anticipated money unanticipated money and output 1873 1930 i introduction this paper examines the roles of anticipated and unanticipated money in the period between the civil war and the depression 1 such an examination is warranted for at least two reasons first estimation of the impact of anticipated and unanticipated money on output for historical periods can enhance our understanding of the responses of economic activity to these key variables 2 second recent work has shown that traditional historical estimates of output may be faulty see romer 1986a 1986b 1986c 1988 not only do most studies investigating the economic roles played by anticipated and unanticipated money concentrate on the post world war ii era those that discuss the period before world war ii such as rush 1985 1986 use traditional data indeed despite the interesting analyses by rush if the validity of the conventional data on output and unemployment for the era under consideration is rejected then virtually no results on the importance of monetary and real factors for economic activity are available for this important period thus further discussion of this topic is needed to answer two important questions what do the revised data show us about the historical economy do these revisions change the inferences drawn about monetary influences on economic activity the analysis presented here is comprehensive in that a wide range of output measures are employed both in terms of the types of output and in terms of the manner in which the output measures are constructed given this variety in the output measures consistent results on the effects of anticipated and unanticipated money across output measures indicate that conclusions drawn from the analysis are robust in particular the empirical results presented below support the following hypotheses i that anticipated m2 and monetary base growth have no effect on output regardless of the output measure used ii that unanticipated m2 and monetary base growth do effect output regardless of the output measure used and iii that changes in financial intermediation may be important for the evolution of output over time support for hypotheses i and ii is consistent with the monetary explanation of business cycles support for hypotheses iii may be consistent with real explanations of business cycles if exogenous shocks to the monetary production technology subsequently affect output 3 taken together the joint support for hypotheses i iii suggests that at a minimum neither the real nor the monetary explanations for historical u s business cycles can be discounted without additional work the remainder of the paper is organized as follows section ii presents a brief overview of the historical period under consideration along with a discussion of prior work on the effects of anticipated and unanticipated money on output determination during this time period section iii discusses the data and the methodology the empirical results are presented in section iv and the conclusions in section v ii overview the historical period the period under investigation 1873 1930 is one of substantial economic change banking panics the return to the gold standard the founding of the federal reserve system and world war i are some of the more important events occuring during this period we consider the role played by expected and unexpected money in output determination for several major subperiods while data availability largely determined the selection of these subperiods they generally correspond to major economic events despite the structural and institutional changes over the period we also examine the roles of anticipated and unticipated money growth in the determination of output over the entire time period to be valid tests of the impact of money growth on output require a reasonable degree of homogeneity in the economic environment

the effect of exchange rate variability on us shareholder wealth we examine the relationship between financial crisis exchange rate variability and equity return volatility for us multinationals empirical analysis of the major financial crises of the last decades reveals that stock return variability increases significantly in the aftermath of a crisis even relative to the increase in stock return volatility for other firms belonging to the same industry and market capitalization class in conjunction with this increase in total volatility there is also an increase in stock market risk for multinational firms moreover trade and service oriented industries appear to be particularly sensitive to these changing exchange rate conditions

the effects of international operations on the market value of the firm theory and evidence this paper investigates the existence of monopoly rents associated with international operations in a market value theoretic framework the benefits of international operations evolve from such factors as 1 imperfections in the product and factor markets 2 differential international taxation and 3 imperfections in the financial markets in this paper these factors are subject to an equilibrium analysis in the context of recent advances in financial theory in particular imperfections in the financial sector arising from corporate international diversification are examined in a framework which allows a supply adjustments by multinational firms and b the interaction of barriers to international capital flows faced by both firms and investors taking the u s capital market and investors as a base we then specify the conditions under which the foregoing imperfections get priced out in an equilibrium these pricing effects cannot be detected empirically through the methodologies employed by the existing studies which examine the effects of corporate international diversification indeed it was an attempt to rescue the limitations of these studies which initially motivated our paper the existing empirical inquiries into this area rely on traditional risk adjusted performance measures e g 7 or international analogs of return generating processes e g 1 8 instead at the empirical level we employ a value based method which is in the same vein of the thomadakis 17 approach developed to identify the monopoly benefits of industrial market structure we conduct the tests over subperiods characterized by differential government controls in an attempt a to separate the pure financial motives for multinationality from other motives and b to detect if the benefits of international operations carry through recent periods

currency devaluation and stock market response an empirical analysis abstract we study local stock market reaction to currency devaluation by a country s central bank devaluations appear to be anticipated by the local stock markets and there are significant negative abnormal returns even one year prior to the announcement of the devaluation a negative trend in stock returns persists for up to one quarter following the first announcement and then becomes positive thereafter suggesting a reversal we explore whether changes in macroeconomic variables prior to currency devaluations are related to abnormal stock returns we find that stock returns are significantly lower if the devaluation is larger and if the country is a developing nation furthermore stock markets decline more around devaluations if reserves are lower if the real exchange rate has depreciated over the prior years if the capital account has declined if the current account deficit has gone up or if the country credit rating has deteriorated

the determinants of stock price exposure financial engineering and the gold mining industry this paper studies the exposure of north american gold mining firms to changes in the price of gold the average mining stock moves 2 percent for each 1 percent change in gold prices but exposures vary considerably over time and across firms as predicted by valuation models gold firm exposures are significantly negatively related to the firm s hedging and diversification activities and to gold prices and gold return volatility and are positively related to firm leverage simple discounted cash flow models produce useful exposure predictions but they systematically overestimate exposures possibly due to their failure to reflect managerial flexibility

firm strategy and economic exposure to foreign exchange rate movements this study examines the implications of differences in strategy and industry structure for firms economic exposures to foreign exchange rate movements in contrast with previous research using a single currency proxy this study estimates firms exposures using a multiple currency model the empirical evidence from u s manufacturing firms indicates that 13 to 17 percent of firms are exposed to foreign exchange rate movements results from cross sectional analyses reveal that foreign direct investment reduces economic exposure to foreign exchange rate movements

the share price reaction of u k exporters to exchange rate movements an empirical study contrary to prior research this u k based study finds a contemporaneous relation between the foreign exchange rate and the market value of large exporters we also find a weak lagged relationship which suggests that the stock market takes time to incorporate all of the implications of foreign currency movements into share prices evidence that the nature of this relationship changed when sterling was in the erm is also provided

unemployment insurance and job duration in canada we use data from the canadian 2 year longitudinal labour market activity survey of 1986 87 to estimate the effect of the unemployment insurance ui system on job duration particular attention is focused on the entrance requirements of the ui system which relate eligibility for ui benefits to an individual s recent employment history the article makes operational the ui entrance requirement provisions which take into account variations in the regional unemployment rate controlling for many personal and job characteristics we find evidence that a significant number of jobs terminate when they have reached the duration that would permit a ui claim

exchange rate exposure abstract in this paper we examine the relationship between exchange rate movements and firm value we estimate the exchange rate exposure of publicly listed firms in a sample of eight non us industrialized and emerging markets we find that exchange rate movements do matter for a significant fraction of firms though which firms are affected and the direction of exposure depends on the specific exchange rate and varies over time suggesting that firms dynamically adjust their behavior in response to exchange rate risk exposure is correlated with firm size multinational status foreign sales international assets and competitiveness and trade at the industry level

a currency preferential approach to international equity investment we propose a timex strategy for reducing the foreign exchange risk associated with international equity investment pertaining to countries with currencies correctly or undervalued by the standard of ppp the performance of timex is examined from the perspectives of eight developed nations with long histories of free floating currencies based on the data from 1986 q1 to 2014 q4 we find unambiguous evidence for the superior performance of timex in the foreign exchange market compared with the passive diversification strategy and the morgan stanley capital international msci world index timex offers higher total returns and risk adjusted total returns when rebalanced every 6 or 12 months for investors based in all eight countries under study when rebalanced at a 3 year interval timex outperforms the passive diversification and the msci world index for five and all eight countries respectively

exchange rate variability and the riskiness of u s multinational firms evidence from the breakdown of the bretton woods system abstract we examine the relation between exchange rate variability and stock return volatility for u s multinational firms and decompose this relation into components of systematic and diversifiable risk focusing on two five year periods around the 1973 switch from fixed to floating exchange rates we find a significant increase in volatility of monthly stock returns corresponding to the period of increased exchange rate variability even relative to the increase in stock return volatility for three control samples in conjunction with this increase in total volatility there is also an increase in market risk beta for multinational firms

the great crash and the onset of the great depression this paper argues that the collapse of stock prices in october 1929 generated temporary uncertainty about future income which led consumers to forgo purchases of durable goods that the great crash generated uncertainty is evidenced by the decline in surety expressed by contemporary forecasters that this uncertainty affected consumer behavior is shown by the fact that spending on consumer durables declined drastically in late 1929 while spending on perishable goods rose slightly this effect is confirmed by the fact that there is a significant negative relationship between stock market variability and the production of consumer durables in the prewar era

an empirical analysis of oil price shocks in the interwar period i introduction post world war ii experience demonstrates that disturbances to aggregate supply are important determinants of aggregate economic performance a casual glance at the post 1970 data strongly suggests a correlation between shocks to the price of oil and recession hamilton 1983 formally demonstrates that this correlation arises from what appears to be a causal link that runs from oil price increases to reduced economic activity the sequence of oil price increases followed by recession characterizes every post world war ii economic downturn in the u s with the exception of 1960 61 other research confirms the critical role of supply shocks in explaining post world war ii macroeconomic performance burbidge and harrison 1984 employ vector autoregressions vars to examine the impact of oil price shocks over the 1962 82 period for several countries they conclude that these shocks played a large role in deepening the recessions of the 1970s with the impact on the 1973 74 recession much greater than that of 1979 80 tatom 1988 estimates the impact of the 1979 80 increase in the relative price of oil and reports that this shock reduced the amount of output that could be produced with available labor and capital by 5 7 percent thoma 1992 re examines the work of litterman and weiss 1985 and finds that the ex ante real interest rate is not exogenous to supply shocks contrary to what is reported in litterman and weiss using annual data over the 1948 82 period loungani 1986 shows that any correlation between an index of the dispersion of unemployment across industries and the aggregate unemployment rate is due to the dispersion index s collinearity with oil price shocks once this collinearity is accounted for the dispersion index has no explanatory power to account for movements in the aggregate unemployment rate while the evidence for the causal link between supply shocks and output appears most dramatic for the post 1970 data hamilton 1983 argues that the entire post war period be treated as a continuous whole the enduring regularity of the oil price shock recession relation in this period leads to a natural question is there any evidence that oil price shocks either positive or negative played any role in the cyclical fluctuations and secular expansion of the 1920s and the great depression figure 1 presents a plot of the relative price of oil defined precisely in section ii for the 1921 1 1938 6 period we observe a number of sharp movements in the relative price of oil that suggest an assessment of the empirical impact of oil price shocks during the interwar period is warranted accordingly we investigate the effects of oil price shocks during the interwar period within the context of a small macroeconomic model 1 the empirical framework is a var model that consists of output the price level the monetary base the m2 money multiplier the commercial paper rate government spending a financial intermediation variable and a measure of oil price shocks these are variables frequently found in small macroeconomic models monthly data for the period 1924 2 1938 6 are used to specify and estimate the model we evaluate the impact of oil price shocks on prices and output through computation of variance decompositions the standard errors reported are generated through monte carlo simulations historical decompositions for the 1929 9 1938 6 period are also computed so we can specifically examine the effects of oil price shocks over the sample period that includes the great depression we chose the var modeling approach because there is little agreement on the appropriate structural model and var estimation places few restrictions on the way in which the system s variables interact in the specification and estimation of the model all variables are treated as jointly determined no a priori assumptions are made about the exogeneity of any of the system s variables at this stage of analysis

foreign exchange exposure of exporting and importing firms abstract the existing literature reports insignificant total exposure for multinational or exporting firms where total exposure incorporates both firm specific and macroeconomic effects we propose a dual effect hypothesis to explain this result which seemingly contradicts conventional wisdom according to our proposed hypothesis firms are affected by both the domestic economy and foreign markets these effects are at least partially offsetting for exporters and additive for importers the resulting predictions of insignificant total exposure for exporters and positive total exposure for importers are borne out in our tests the literature also reports insignificant residual exposure for multinationals or exporting firms where residual exposure estimates the firm specific exposure this result is explained by biases in the residual exposure estimates introduced by the choice of the value weighted market index as the control portfolio we propose an equally weighted portfolio of purely domestic firms as an alternative portfolio to reduce such biases and report significantly negative exposure for exporters and significantly positive exposure for importers as predicted by theory

the exchange rate exposure of u s multinationals this article examines the exposure of u s multinationals to foreign currency risk evidence is presented that the relationship between stock returns and exchange rates differs systematically across multinationals given these results the study focuses on the determinants of exchange rate exposure the comovements between stock returns and the value of the dollar is found to be positively related to the percentage of foreign operations of u s multinationals copyright 1990 by the university of chicago

a panel project on purchasing power parity mean reversion within and between countries abstract previous time series studies have shown evidence of mean reversion in real exchange rates deviations from purchasing power parity ppp appear to have half lives of approximately four years however the long samples required for statistical significance are unavailable for most currencies and are potentially inappropriate because of regime changes in this study we re examine deviations from ppp using a panel of 150 countries and 45 annual post wwii observations our panel shows strong evidence of mean reversion that is similar to that from long time series ppp deviations are eroded at a rate of approximately 15 annually i e their half life is around four years such findings can be masked in time series data but are relatively easy to find in cross sections

unexpected monetary disturbances during the gold standard era abstract this empirical paper uses the barro methodology of estimating unexpected monetary shocks to determine the effect these shocks had on real output in the u s during the gold standard era between 1880 and 1913 it also investigates whether changes in a measure of financial intermediation had real effects the results indicate that neither expected nor unexpected money shocks affected output changes in financial intermediation however were significantly correlated with output this result lends support to theories which stress the endogeneity of broad measures of the money supply

flight to quality and correlation between currency and stock returns abstract we document that capital flows in and out of emerging or developed markets are sensitive to global equity market conditions capital tends to move out of emerging into developed countries in global down markets leading to depreciation appreciation of emerging developed currencies this generates a positive negative correlation between currency and equity in emerging developed markets which is amplified by the magnitude of the capital movement we also verify that hedging currency risks may undo the natural hedge and increase the total return volatility under negative correlation

foreign currency denominated debt an empirical examination we examine the determinants of debt issuance in 10 major currencies by large u s firms using the fraction of foreign subsidiaries and tests exploiting the disaggregated nature of our data we find strong evidence that firms issue foreign currency debt to hedge their exposure both at the aggregate and the individual currency levels we also find some evidence that firms choose currencies in which information asymmetry between domestic and foreign investors is low we find no evidence that tax arbitrage liquidity of underlying debt markets or legal regimes influence the decision to issue debt in foreign currency

using survey data to resolve the exchange risk exposure puzzle evidence from u s multinational firms while in previous literature foreign currency exposure is estimated to be surprisingly small and insignificant we question in this paper the rationality assumption and show that the traditional use of realized exchange rate changes to approximate unexpected currency shocks leads to a strong underestimation of the influence that exchange rates play in determining firm valuations in light of a unique survey data base of individual exchange rate expectations we distinguish between realized and unexpected foreign currency movements and find that half of our sample of 935 u s firms with real operations in foreign countries is significantly exposed to unexpected exchange rate movements in line with previously reported results foreign exchange risk exposure is found to become increasingly perceptible when the return horizon is lengthened the difference between the exposure to realized versus unexpected exchange rate movements is however decreasing when lengthening the horizon suggesting that the more market participants disagree about the future path of currency values the less investors and or managers are likely to use the publicly available forecasts in their pricing and hedging decisions

is hedging successful at reducing financial risk exposure abstractthis article analyses whether firms use risk management instruments for hedging or speculative purposes first by analysing the relationship between the firm s stock returns and financial risks in 567 euronext firms we measure the firm s exposure to risk next we investigate the effect of hedging in such exposures addressing simultaneously the endogeneity of hedging decision through a treatment effect methodology we have found that firms in our sample display higher percentages of exposure when weighed against preceding studies and confirmed that hedging reduces the level of the underlying financial exposure concluding that firms use risk management instruments with hedging purposes

the cost of capital in international financial markets local or global abstract this paper analyzes to what extent international and domestic asset pricing models lead to a different estimate of the cost of capital for an individual firm under the maintained assumption of perfect international financial integration we distinguish between i the multifactor solnik sercu icapm including both the global market portfolio and exchange rate risk premia and ii the single factor domestic capm we use a sample of 3 293 stocks from nine countries in the period 1980 1999 the domestic capm yields a significantly different estimate of the cost of capital from the multifactor icapm for only five percent of the firms in our sample we attribute the close correspondence between local and global pricing to strong country factors in individual stock returns which are probably due to lack of real integration our results reinforce the home bias puzzle

financial analysts forecasts of earnings a better surrogate for market expectations abstract the specification of the market expectation of accounting numbers is a common feature of many empirical studies in accounting and finance givoly and lakonishok 1979 found that financial analysts forecasts have information content this study evaluates the quality of analysts forecasts as surrogates for the market expectation of earnings and compares it with that of prediction models commonly used in research results indicate that prediction errors of analysts are more closely associated with security price movements suggesting that analysts forecasts provide a better surrogate for market expectations than forecasts generated by time series models the study also identifies factors that might contribute to the performance of the financial analysts forecasts the broadness of the information set employed by analysts and to a lesser extent their reliance on information released after the end of the fiscal year appear to be important contributors to their performance

the elusive flypaper effect abstract the flypaper effect is the common empirical result that lump sum intergovernmental grants stimulate more local government spending than increases in private income which are theoretically equivalent in this paper four of the best known explanations of the flypaper effect are tested using data from michigan school districts none of these explanations are confirmed by the data the cause of the flypaper effect is likely to be much more deeply rooted in the nature of local decision making than is currently recognized

operational hedges and the foreign exchange exposure of u s multinational corporations this paper examines the impact of operational hedges of us multinational corporations mncs on their exchange rate exposure the two important contributions of this study are first it documents the importance of operational hedges as significant determinants of exchange rate risk as measured by breadth and depth dimensions of the mnc foreign subsidiary network second this finding remains robust even after examining the impact of operational hedges on exposure separately for negatively and positively exposed mncs

explaining exchange rate risk in world stock markets a panel approach using a garch approach we estimate a time varying two factor international asset pricing model for weekly equity index returns of 16 oecd countries a trade weighted basket of exchange rates and the msci world market index are used as risk factors we find significant currency risk exposures in country equity index returns we then explain these currency betas using several country specific macroeconomic variables with a panel approach we find that imports exports credit ratings and tax revenues significantly affect currency risks in a way that is consistent with some economic hypotheses similar conclusions are obtained by using lagged explanatory variables and thus these macroeconomic variables may be useful as predictors of currency risk exposures our results are robust to a number of alternative specifications

a re examination of exposure to exchange rate risk the impact of earnings management and currency derivative usage abstract in an attempt to explain the weak evidence of priced exchange rate risk we hypothesize that in addition to currency derivative usages earnings management serves as another factor contributing to a reduction in exchange rate exposure our evidence reveals that earnings management activities particularly those undertaken for the purpose of income smoothing significantly reduce firm specific exchange rate exposure and that such role is particularly important if appropriate currency derivative instruments are limited these results complement prior attempts to explain the puzzle of unpriced exchange rate risk the investigation also highlights the importance of recognizing different managerial purposes behind discretionary accruals

estimates of the variance of u s inflation based upon the arch model it is generally agreed that the unpredictability of future inflation is a major component of the welfare loss associated with inflation perfectly predicted inflation might induce some costs through institutional rigidities governmental interference and transaction costs but in the long run these should be rather minimal as these institutions adopt various forms of indexing when inflation is unpredictable risk averse economic agents will incur a loss even if prices and quantities are perfectly flexible in all markets inflation is a measure of the relative price of goods today and goods tomorrow thus uncertainty in tomorrow s price impairs the efficiency of today s allocation decisions friedman in his nobel lecture 8 argues convincingly that higher variability of inflation would lead to decreased output ceteris paribus he then conjectures that higher rates of inflation are generally associated with higher variability of inflation and presumably greater uncertainty about future rates if this is true then higher rates of inflation would also be associated with low levels of output which implies a positively sloped phillips curve this paper uses a new statistical technique arch to estimate the conditional mean and variance of inflation from u s time series data the main finding is that the variance of inflation in the seventies was only slightly greater than in the sixties

monetary factors in the great depression this paper examines the role of monetary policy in the early stages of the great depression and considers the mechanism whereby this policy may have affected real activity i conclude that the depression was preceded by a dramatic shift towards a highly contractionary monetary policy the economic impact of this policy seems unlikely to have come through the conventional keynesian channels of a shortage of liquidity and high ex ante real interest rates but instead may have operated through unanticipated deflation and after 1930 through the disruption of financial intermediation as a consequence of the banking panics

uncertainty irreversibility durable consumption and the great depression what was the role of uncertainty in the great depression this paper uses a calibrated general equilibrium model to show that in response to an increase in uncertainty agents increase expenditure on irreversible durable goods and reduce investment in irreversible physical capital these relative movements occur because durable goods provide a store of utility and are less irreversible than physical capital these substitutions are unclear at the start of the great depression but are clearly visible at the deep end of it in 1932 when the volatility of stock returns is consistently high coefficients on the variance which is consistent with the uncertainty hypothesis both the theoretical hypothesis and its empirical tests are of a partial equilibrium nature yet the great depression was a general equilibrium event this paper puts the uncertainty argument explicitly in a general equilibrium model with consumer durables and capital goods both subject to irreversibility constraints i associate income uncertainty with the stochastic process driving output fluctuations and an increase in uncertainty is modelled as a mean preserving spread on the distribution of this shock the general equilibrium setup also incorporates a specific notion of irreversibility namely that goods are irreversible if there are no buyers when one wants to sell the test of the uncertainty hypothesis in general equilibrium is a simulation of a calibrated version of the model what makes the reaction to a mean preserving spread nontrivial is the clash of the theoretical predictions of precautionary savings and irreversible investment in a general equilibrium context savings should increase and investment should fall to complicate matters durable goods have components of both consumption and investment so what was the role of uncertainty in the great depression in this setup a calibrated model provides a simple answer higher uncertainty makes agents cut capital investment and increase expenditure on durables there are two reasons for this the first is that durables are the least irreversible of the two assets in the model and the second is that durable goods act as a store of utility and thus as insurance the view of the uncertainty hypothesis that a cut in expenditure on durable goods is a key response to high uncertainty is not supported by a standard general equilibrium model there may however be some truth in itfbut for the wrong reasons and at the wrong time it is not a fall in durable expenditure per se but rather an increase relative to

financial and political risks in us direct foreign investment this paper examines the risk of us direct foreign investments over the period 1982 98 in 59 host countries the first part of the analysis builds an empirical model to explain the time series and cross country patterns of return on capital the estimation then uses the return on assets roa as a measure of the return on capital and investigates its determinants there are four main findings first the roa in a majority of countries does not simply track the worldwide roa second some cross country differences are explained by financial risks third unexplained country risk is qualitatively and quantitatively related to unobserved political risk fourth unexplained country risk is also compensated with a higher roa enhancing its credibility as a measure of political risk the unexplained country risk is thus used to calculate a new index of political risk ratings for 56 host countries that may be useful to managers investors policymakers and academics
