the term structure of euromarket interest rates an empirical investigation abstract this paper is an empirical investigation of the predictability and co movement of risk premia in the term structure of euromarket interest rates we present regression results which suggest that risk premia in three euromarket term structures and on uncovered foreign asset positions move together we test formally the hypothesis that these risk premia move in proportion to a single latent variable we are unable to reject this hypothesis the single latent variable model can be interpreted as in hansen and hodrick 1983 and hodrick and srivastava 1984 as a specialization of the icapm in which assets have constant betas on a single unobservable benchmark portfolio

monetary policy regime changes and the risk premium in the foreign exchange markets abstract this paper reports an empirical relationship between conduct of monetary policy and the foreign exchange risk premium using garch 1 1 the time variation of the risk premium is shown to depend significantly on the changes in the monetary policy regime

testing for the absence of expected real profits from forward market speculation abstract this paper tests for the absence of expected real profits from forward market speculation it contrasts with the literature that has considered opportunities for expected nominal profit from speculation that is profits denominated in one of the currencies these studies assume money illusion on the part of market participants but this paper does not empirical results fail to find evidence of unexploited real profit opportunities

the pricing of forward contracts for foreign exchange this paper investigates the nature of observed deviations from the unbiased expectations hypothesis in the forward foreign exchange market if these deviations are due to risk premia then the same premia should be observed in nominal bonds denominated in different currencies this condition imposes testable restrictions on the parameters of a multivariate regression model the empirical results are consistent with a world in which time varying risk premia cause the observed deviations from unbiased expectations

in search of the exchange risk premium a six currency test assuming mean variance optimization abstract a number of authors examining deviations of actual rates of currency depreciation from forward discounts have claimed to find evidence of risk premiums if these deviations are indeed partly due to risk premiums rather than being entirely due to expectational errors then they should be systematically related to those variables on which risk premiums are thought to depend finance theory tells us that if investors optimize with respect to mean and variance the risk premium depends in a specific way on 1 the supplies of assets denominated in the various currencies 2 the variance covariance matrix of the rates of return and 3 the coefficient of risk aversion the null hypothesis of this paper is that the coefficient of risk aversion is zero countries assets are perfect substitutes and risk premiums are nonexistent the alternative hypothesis is that rates of return are systematically related to asset supplies by a macroeconomic portfolio balance function the maximum likelihood technique used dominates previous attempts to find such a relationship in that the parameters of the portfolio balance function are constrained to depend on the variance covariance matrix as the finance theory says they should on the other hand the technique also dominates previous applications of the finance theory in that the expected returns are allowed to vary over time as the macroeconomic portfolio balance theory says they should the paper s finding is a statistical inability to reject the null hypothesis for a portfolio of six currencies although this could be due to low power in the test

carry trades order flow and the forward bias puzzle we investigate the relation between foreign exchange fx order flow and the forward bias we outline a decomposition of the forward bias according to which a negative correlation between interest rate differentials and order flow creates a time varying risk premium consistent with that bias using 10 years of data on fx order flow we find that more than half of the forward bias is accounted for by order flow with the rest being explained by expectational errors we also find that carry trading increases currency crash risk in that order flow generates negative skewness in fx returns

the persistence of the peso problem when policy is noisy abstract the peso problem the market s belief that a discrete event may occur has frequently been blamed for the persistence of on average mistaken forecasts of macroeconomic variables this paper demonstrates how beliefs that a policy process may have switched can induce apparent ex post biased forecasts of exchange rates even after the switch has occurred furthermore during this peso problem period exchange rates may appear to contain a speculative bubble component since they will systematically deviate from the levels implied by observing fundamentals ex post and the conditional variance of exchange rates will exceed the variance implied by observing fundamentals

energy taxes and economic performance a regional general equilibrium analysis abstract a computable general equilibrium model allowing for substitution among oil and other energy and non energy inputs is used to simulate impacts on energy use and macroeconomic performance of two kinds of energy taxes a uniform energy consumption tax and a crude oil severance tax results show that it is possible effectively to decouple both oil and energy use from macroeconomic activity although the severance tax achieves domestic oil conservation at the cost of a corresponding rise in oil imports

profits risk and uncertainty in foreign exchange markets this paper examines the properties of nominal profits from speculation in dollar dominated forward contracts using a representative agent cash in advance model modified to allow for heteroscedasticity in the exogenous processes the model is simulated by estimating exogenous processes from the data and the remaining free parameters with a simulated method of moments technique simulated expected profits are variable heteroskedastic and serially correlated but the magnitude of these second moments fall short of those of the predictable component of observed profits on the u s dollar as in the actual data simulated forward rates display biasedness in predicting simulated future spot rates

interest rate parity and the exchange risk premium evidence from panel data abstract this paper provides evidence that a time varying risk premium is responsible for the rejection of the interest rate parity theory we use a panel data set of returns on eurocurrency deposits and employ cross section time series methods to account for common movements in risk premia across deposits denominated in different currencies

tests of international capm with time varying covariances we perform maximum likelihood estimation of a model of international asset pricing based on capm we test the restrictions imposed by capm against a more general asset pricing model the betas in our capm vary over time as the supplies of assets change and as the conditional covariances or returns on those assets change we let the covariances change over time as a function of macroeconomic data and an alternative model allows the covariances to follow a multivariate arch process we also can identify a modified capm model with measurement error we find that the estimated capm performs much better when variances are not constant over time nonetheless capm is rejected in favour of the lessrestricted model of asset pricing

a critique of latent variable tests of asset pricing models abstract latent variable tests of asset pricing models make assumptions about the joint distribution of observable returns and unobservable benchmark returns these tests can falsely accept models when a mean variance efficient portfolio other than the benchmark satisfies the distributional assumptions imposed on the benchmark portfolio also because the assumptions are untestable there is no way to discover whether a model is being rejected because the assumptions are false without these assumptions however latent variable tests can be viewed only as tests of distributional hypotheses about mean variance efficient portfolios of unknown composition

the time series properties of the risk premium in the yen dollar exchange market summary in this paper a var model is employed to construct a measure of the conditional expectations of the future yen dollar spot rate this measure allows us to examine the dynamics of an ex ante time series for the risk premium in the market the var model produces better forecasts than the survey responses for turbulent periods such as 1981 1982 and 1984 1985 the var generated expectations are then used to construct a risk premium time series this risk premium ieerie series seems to be more reliable than the ones obtained using either survey data on expectations of the future spot exchange rate or the ex post realized spot exchange rate tests on the risk premium series suggest that a risk premium was present but that it was virtually constant throughout the sample the conditional variance of the risk premium changed over time but its unconditional distribution seemed stable across subsamples despite these features the volatility of the series was substantial and varied considerably throughout the sample

pricing capital assets in an international setting an introduction this paper shows how differences across countries of 1 inflation rates 2 consumption baskets of investors and 3 investment opportunity sets of investors matter when one applies capital asset pricing models in an international setting in particular the fact that countries differ is shown to affect the portfolio held by investors the equilibrium expected returns of risky assets and the financial policies of firms

do asset demand functions optimize over the mean and variance of real returns a six currency test abstract international asset demands are functions of expected returns optimal portfolio theory tells us that the coefficients in this relationship depend on the variance covariance matrix of real returns but previous estimates of the optimal portfolio 1 assume expected returns constant and 2 are not set up to test the hypothesis of mean variance optimization we use maximum likelihood estimation to impose a constraint between the coefficients and the error variance covariance matrix for a portfolio of six currencies we are able statistically to reject the constraint evidently investors are either not sophisticated enough to maximize a function of the mean and variance of end of period wealth or else are too sophisticated to do so

an examination of uncovered interest rate parity in segmented international commodity markets we examine the effect of segmented commodity markets on the relation between forward and future spot exchange rates in a dynamic economy we calculate the slope coefficient in our theoretical economy from regressing exchange rate changes on forward premia with reasonable parameter values the slope coefficient is less than unity however even for extreme parameters the slope is not less than zero as found in the data a negative slope coefficient in a nominal version of the model requires the covariance between monetary shocks and relative output shocks to be significantly negative in contrast to the covariance in the data one of the most studied relations in international finance is that between forward exchange rates and future spot rates empirical tests typically find that when one regresses changes in spot rates on forward premia the slope coefficient is less than one and often negative this result is called the forward bias anomaly and implies that the returns from investing in forward exchange contracts are predictable our objective is to examine the effect of segmentation of international commodity markets on the relation between the forward premium and the change in the spot rate segmentation of commodity markets is modeled by introducing a cost for transferring goods across countries giving rise to deviations from purchasing power parity ppp in this article we first derive the theoretical implications of the effect of segmentation on the forward bias in a dynamic general equilibrium model and then analyze a calibrated version of the model our analysis serves as a useful benchmark to study how much of the predictable deviations from uncovered interest parity uip can be explained by endogenous deviations from ppp

accounting for forward rates in markets for foreign currency absteract forward and spot exchange rates between major currencies imply large standard deviations of both predictable returns from currency speculation and of the equilibrium price measure the intertemporal marginal rate of substitution representative agent theory with time additive preferences cannot account for either of these properties we show that the theory does considerably better along these dimensions when the representative agent s preferences exhibit habit persistence but that the theory fails to reproduce some of the other properties of the data in particular the strong autocorrelation of forward premiums since the advent of flexible exchange rates in the early 1970s a large body of statistical work has established that forward rates for major currencies are not optimal predictors of future spot rates relevant evidence is reported in studies by baillie lippens and mcmahon 1983 bekaert 1991 bilson 1981 boothe and longworth 1984 cumby 1988 cumby and obstfeld 1984 fama 1984 gregory and mccurdy 1984 hansen and hodrick 1983 hodrick and srivastava 1984 and korajczyk and viallet 1990 a more complete list of references is provided by hodrick 1987 these papers indicate that returns from speculation in forward and spot currency markets are predictable and that the predictable components vary considerably over time a number of alternative explanations have been offered for the predictable variation in foreign currency market excess returns kaminsky 1988 korajczyk 1985 and krasker 1980 suggest that infrequent extreme events may make returns appear predictable in small samples the so called peso problem lewis 1989 argues that rational learning following infrequent changes in the process governing equilibrium prices can explain part of the ex post predictability of currency returns froot and frankel 1989 and froot and thaler 1990 examine the hypothesis that market forecasts of future spot

the world real interest rate stochastic index number perspectives abstract in a recent paper gagnon and unferth 1995 is there a real world interest rate j int money finance 14 845 855 test the hypothesis of real interest rate equality by regressing real interest rates for all major countries on dummy variables for each country and each period we show that this model can be interpreted as an application of the stochastic approach to index numbers this approach leads to estimates of and standard errors for the real rate for the world as a whole which have appealing index number interpretations and foundations we also extend gagnon and unferth s approach by weighting countries to recognise their differing importance in the world economy in terms of relative gdp and trade weighting does not lead to appreciable changes in the results however when the wpi which gives more prominence to goods entering into international trade is used as the deflator our results indicate that real rates are equalized internationally

the behavior of eurocurrency returns across different holding periods and monetary regimes recent empirical studies of the risk premium across foreign exchange and other asset markets such as equity and longer term bonds have found conflicting evidence about the latent variable model restrictions of the consumption based intertemporal capital asset pricing model while studies using data for holding periods of one month or less generally reject the model evidence using three month holding periods indicates that the model cannot be rejected when including the returns on long relative to short deposit rates this paper investigates the sources of differences in results using returns on foreign exchange and eurocurrency deposits at three different maturities

term premiums and the integration of the eurocurrency markets abstract this paper provides comparative evidence on the time variation of expected returns across the term of eurocurrency markets first it is shown that forward spot spreads contain substanial information about future changed in 1 month to 5 year rates both in the eurodollar and eurodm markets next a latent variable model is constructed with different benchmark portfolios across currencies integration implies that the time variation of the benchmark portfolios must be the same across currencies little evidence is found against integration of the eurocurrency markets jel g15 g12

monetary policy liquidity and foreign exchange markets an exploration abstract this paper explores empirically the fluctuations of money demand arising from financial markets fluctuations in financial markets liquidity are reflected in interest rates and asset returns the paper uses daily data on the swiss franc and other currencies from january 1 1980 until december 31 1987 and is based on a priori knowledge on the timing of liquidity shocks in the empirical analysis i ask whether at the time liquidity shocks occur abnormal rates of return can be observed in the foreign exchange markets

heterogeneous expectations and tests of efficiency in the yen dollar forward exchange rate market this paper examines the efficiency of the forward yen dollar market using micro survey data conventional tests of unbiasedness do not correspond directly to the zero profit condition instead we use the survey data to calculate potential profits of individual forecasters based on a natural trading rule we find that although the survey data are not the best predictor of future spot rates in terms of typical mean square forecast error criteria the survey data can be used to obtain on average positive profits however these profits are small and highly variable similar results are found when we examine profits generated by a trading rule using regression forecasts the profits are found to be correlated with risk type variables but not other available information

should the holding period matter for the intertemporal consumption based capm abstract empirical studies of the restrictions implied by the intertemporal capital asset pricing model across different asset markets have found conflicting evidence this paper asks whether an auxiliary assumption implicit in these tests could be responsible for the pattern of rejections this auxiliary assumption requires that covariances of returns with consumption move in constant proportion over time the paper tests this condition empirically using data on foreign exchange bonds and equity returns interestingly the evidence suggests that the tendency to reject the intertemporal consumption based asset pricing relationship depends upon the inadequacy of the auxiliary assumption not necessarily the relationship itself

the time variation of expected returns and volatility in foreign exchange markets this article analyzes the time variation in conditional means and variances of monthly and quarterly excess dollar returns on eurocurrency investments all results are based on a vector autoregression with weekly sampled data on exchange rate changes and forward premiums of three currencies both past exchange rate changes and forward premiums predict future forward market returns moreover past forward premium volatilities predict the volatility of exchange rates expected forward market returns are very variable and persistent and exhibit marked comovements these results carry over to cross rate e g yen mark investments as well

the persistence of real interest differentials abstract this paper applies kalman filtering techniques to estimate the persistence of ex ante real interest differentials identification results for state space models applicable in other contexts are presented and exploited in the model estimation ex ante real interest differentials for the period 1973 1987 are found to be relatively short lived and mean reverting to zero thus providing empirical support for theoretical models of economic interdependence characterized by real rate equality in the long run steady state for the sample considered the variability of the differentials relative to the u s is found to be larger than that relative to germany

risk premia carry trade dynamics and economic value of currency speculation in this paper we derive the dynamics and assess the economic value of currency speculation by formalizing the concept of a trader inaction range we show that exchange rate returns comprise a time varying risk premium and that uncovered interest parity uip holds in a speculative sense the often cited forward bias puzzle originates from the omission of the risk premium in standard uip tests consistent with its popularity among market professionals the carry trade strategy can be rationalized as it systematically collects risk premia and generates economic value when applied in multi currency portfolios

multiple maturities and time varying risk premia in forward exchange markets abstract this paper derives the necessary conditions for an intertemporal optimization problem faced by an international investor who can enter forward contracts of several maturity dates and simultaneously borrow in domestic money markets the model parameters are estimated and the overidentifying restrictions are tested using hansen s proposed gmm technique the restrictions are strongly rejected when forward premia are used as instruments the risk neutral specification is rejected when expenditures on non durables and services are used as the consumption measure possible explanations for these rejections are provided

tests of three parity conditions distinguishing risk premia and systematic forecast errors abstract this study provides evidence that uncovered interest differentials between currencies cannot be attributed to either risk premia or systematic forecast errors alone the evidence is based on developing joint tests of three parity conditions uncovered interest parity purchasing power parity and real interest parity the study tests parameter restrictions based on knowing that risk premiums only affect nominal and real interest differentials but not inflation differentials while systematic errors in forecasting exchange rates only affect nominal interest differentials and inflation differentials but not real interest differentials the study finds a variety of cases where deviations from some or all of the parity conditions can be systematically related to variables currently known to investors and borrowers the most intriguing evidence is that for some currencies these deviations from parity are perfectly correlated as if they were driven by a common factor

ceo duality succession planning and agency theory research agenda in response to harris and helfat s commentary on our article one hat too many key executive plurality and shareholder wealth we suggest that their arguments are quite plausible but we believe further empirical tests are needed these proposed tests are described in our response 1998 john wiley sons ltd

is it signalling exchange intervention and the dollar deutschemark rate abstract the portfolio balance channel for sterilised intervention is tested by examining the effects of changes in relative asset supplies on the dollar deutschemark rate during the 1980s in contrast to previous studies we control for any signalling effects of central bank intervention and find a weak but statistically significant portfolio balance influence on the exchange rate

conditional variance and the risk premium in the foreign exchange market abstract we investigate the existence of a risk premium in the foreign exchange market based on the conditional variance of market forecast errors the forecast errors are assumed to follow the arch process introduced by engle 1982 estimation and diagnostic testing of the model are discussed and results are presented for the currencies of the united kingdom france germany japan and switzerland
