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

methodical madness technical analysis and the irrationality of exchange rate forecasts substantial empirical research documents that exchange rate forecasts are not formed rationally this paper identifies a common technical trading signal the head and shoulders pattern as a potential source of departures from rationality in exchange rate forecasts forecasts based on this pattern are evaluated for daily dollar exchange rates over 1973 to 1994 using two criteria for rationality profitability and efficiency resulting profits replicable in real time are tested for statistical significance using a bootstrap technique we find that the rule is profitable but not efficient since it is dominated by simpler trading rules

pattern based expectations international experimental evidence and applications in financial economics abstract we study how subjects extrapolate simple patterns in financial time series in order to develop a descriptive model of actual agent behavior the laboratory experiment for this analysis was conducted in germany and japan statistical analyses indicate considerable similarity in expectations formation across cultures and document that agents expectations are at variance with the notion of standard trend extrapolation the paper then proposes a method for computing expectations for any economic time series based on the experimental data such pattern based expectations are shown to explain stock prices and the dynamics of the forward discount on the foreign exchange market

the speculative efficiency hypothesis the hypothesis that forward prices are the best unbiased forecast of future spot prices is often presented in the economic and financial analysis of futures markets this paper considers the hypothesis independently of its implications for rational expectations or market efficiency and in order to stress this fact the term speculative efficiency is used to characterize the state envisaged under the hypothesis if a market is subject to efficient speculation the supply of speculative funds is infinitely elastic at the forward price that is equal to the expected future spot price the expected future spot price is a market price determined as the solution to the underlying rational expectations macroeconomic model although the paper is primarily concerned with testing this hypothesis in the foreign exchange market the methodology introduced in the paper is of general application to all futures markets this abstract was borrowed from another version of this item

interest rates and currency prices in a two country world abstract this paper is a theoretical study of the determination of prices interest rates and currency exchange rates set in an infinitely lived two country world which is subject both to stochastic endowment shocks and to monetary instability formulas are obtained for pricing all equity claims nominally denominated bonds and currencies and these formulas are related to earlier closely related results in the theories of money finance international trade

ems exchange rate expectations and time varying risk premia abstract in this paper we examine exchange risk premia employing a survey dataset of ems exchange rates we are able to test a risk premium model directly i e without having to rely on the rational expectations assumption our results indicate that time varying risk premia are present in almost all cases and that a garch in mean specification for the premium is often appropriate

predictability in financial markets what do survey expectations tell us abstract there is widespread evidence of excess return predictability in financial markets for the foreign exchange market a number of studies have documented that the predictability of excess returns is closely related to the predictability of expectational errors of excess returns in this paper we investigate the link between the predictability of excess returns and expectational errors in a much broader set of financial markets using data on survey expectations of market participants in the stock market the foreign exchange market the bond market and money markets in various countries the results are striking first in markets where there is significant excess return predictability expectational errors of excess returns are predictable as well with the same sign and often even with similar magnitude this is the case for foreign exchange stock and bond markets second in the only market where excess returns are generally not predictable the money market expectational errors are not predictable either these findings suggest that an explanation for the predictability of excess returns must be closely linked to an explanation for the predictability of expectational errors

the political economy of inflation and stabilization in developing countries the traditional literature on inflation in developing countries has focused on three main determinants of inflationary pressures a money creation b fiscal imbalances and c cost push elements while the first two factors have been emphasized by authors of a monetarist persuasion cost factors have played a crucial role in the structuralist theories developed during the 1950s and 1960s however more recent analyses on inflation and stabilization have shifted their attention away from traditional direct economic causes of inflation such as money creation toward political and institutional determinants of inflationary forces this new literature which has come to be known as the political economy approach to macroeconomic policy has built on some important insights of game theory and the theory of public choice trying to explain why some governments decide to run large fiscal deficits and to rely heavily on the inflation tax typically in answering these questions this recent strand of the literature has emphasized the role of political instability credibility reputation and political cycles 2 in spite of providing some important new insights into the determinants of inflation this new literature is subject to two limitations first until recently most of the contributions have been theoretical without providing empirical tests on their most important implications and second the emphasis has been almost exclusively on the industrialized countries ignoring the developing nations the purpose of this article is to discuss selectively some of the most important insights of this new literature on policy making from the developing countries perspective i will emphasize the policy implications of this approach to inflationary analysis and discuss some of the limited empirical results

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

the influence of fundamentals on exchange rates findings from analyses of news effects as we survey the literature of macroeconomic news in the foreign exchange market we can by now look back on nearly 30 years of research the first studies which analysed news effects on exchange rates were established in the early 1990s see for example dornbusch almost at the same time meese and rogoff published their influential paper revealing the forecasting inferiority in exchange rates of structural models against the random walk this finding has shocked the pillars of exchange rate economics and thus cast general suspicion on research focusing on fundamentals in this field the eventual rising popularity of event studies can partly be attributed to the re establishment of the raison d etre of exchange rate economics this work focuses on systematically surveying this literature with particular respect to its primary goal i e shedding light on the analytical value of fundamental research thus its major findings are first fundamental news does matter whereas non fundamental news matters to a lesser degree second news influences exchange rates via two separated channels i e incorporating common information into prices directly or indirectly based upon order flow third with a few exceptions the impact of fundamental news on exchange rates is fairly stable over time

does a correct parameter estimate tell a better story about foreign exchange market efficiency abstract this paper demonstrates that the estimated parameters in previous research with wrong signs and absurd sizes do not indicate market inefficiency and market behavior as they appear to in the real world where forecasting errors are substantially large a correct or an unreasonable parameter estimate renders almost identical results specifically we demonstrate that an absolutely unbiased predictor is irrelevant empirically and the unknowingly pursuit of absolute unbiasedness is misleading what needs to be verified is a sufficiently unbiased predictor which may appear to be incredibly biased under the circumstances with expected specified probabilistic errors

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

testing for efficiency and rationality in foreign exchange markets a review of the literature and research on foreign exchange market efficiency and rationality with comments abstract this paper specifies two var models for testing efficiency and expectations in foreign exchange markets the sufficient conditions for efficiency and rational expectations by imposing restrictions on the var parameters are derived based on these models issues on testing efficiency and rationality are discussed with reference to previous empirical studies in the area

differences in beliefs and currency risk premiums this paper studies the importance of heterogeneous beliefs for the dynamics of asset prices we focus on currency markets where the absence of short selling constraints allows us to perform sharper tests of theoretical predictions using a unique data set with detailed information on foreign exchange forecasts we construct an empirical proxy for differences in beliefs we show that this proxy has a strong effect on the implied volatility of currency options beyond the volatility of macroeconomic fundamentals we document that differences in beliefs impact also on the shape of the implied volatility smile on the volatility risk premiums and on future currency returns

cross hedging under multiplicative basis risk cross hedging price risk in an incomplete financial market creates basis risk we propose a new way of modeling basis risk where price risk and basis risk are combined in a multiplicative way under this specification positive prudence is a necessary and sufficient condition for underhedging in an unbiased market using the example of cross hedging jet fuel price risk with crude oil futures we show that the new specification is superior in describing the price series and that optimal cross hedges differ significantly from those derived under the traditional additive cross hedging model

more evidence on the dollar risk premium in the foreign exchange market in this article we develop and estimate an econometric panel data model to capture the common dynamics in dollar risk premia in various forward foreign exchange rates the common component in the dollar risk premium is highly significant and embodies a common pattern of positive serial correlation persistence for the pound the yen and the mark interestingly our results indicate that the dynamics of the forward prediction error can be attributed almost exclusively to this dollar related common component our evidence also suggests that the three different foreign currencies dollar risk premia respond to the common factor to different degrees

a note on the determinants of unexpected exchange rate movements abstract in this paper we study the relative importance of surprises in fundamentals in explaining unexpected exchange rate movements employing a unique survey dataset that contains matched exchange rate and interest rate expectations we are able to derive a number of interesting conclusions a variance decomposition of unexpected exchange rate movements into various components reveals that interest rate news is relatively unimportant but that changes in perceptions about risk premia and more importantly revisions of expectations with regard to future exchange rate levels are crucial in explaining unexpected exchange rate movements

the covariation of risk premiums and expected future spot exchange rates abstract eugene fama 1984 analyzed the variability and the covariation of risk premiums and expected rates of depreciation we employ three statistical techniques that do not suffer from a potential bias in fama s analysis but we nevertheless conffirms his findings in contrast to his interpretation the results are not necessarily at variance with the predictions of a theoretical model of the risk premium increases in expected rates of depreciation of the dollar relative to five foreign currencies are positively correlated with increases in the expected profitability of purchasing these currencies in the forward market and risk premiums have larger variancies than expected rates of depreciation

on the biasedness of forward foreign exchange rates irrationality or risk premia in this article the authors reconsider the k a froot and j a frankel 1989 results on the sources of forward discount bias they question the economic validity of some estimation restrictions that they impose and thus are led to question some of their results the authors employ a new exchange rate survey database that includes european monetary system currencies and use univariate and pooling estimation techniques that impose fewer restrictions than those of froot and frankel to test their hypotheses they find that the bias in the forward discount is attributable to both the failure of rational expectations and the existence of time varying risk premia copyright 1994 by university of chicago press

on the internal consistency of short term medium term and long term oil price forecasts we derive internal consistency restrictions on short medium and long term oil price forecasts we then analyse whether oil price forecasts extracted from the survey of professional forecasters spf conducted by the european central bank ecb satisfy these internal consistency restrictions we find that neither short term forecasts are consistent with medium term forecasts nor that medium term forecasts are consistent with long term forecasts using a more complex expectation formation structure featuring a distributed lag structure however we find stronger evidence of internal consistency of medium term forecasts with long term forecasts

scandinavian forward discount bias risk premia abstract in this article we investigate expectations concerning scandinavian exchange rates with the aid of a survey dataset containing market participants forecasts of the exchange rates our findings indicate that formal tests of forward discount bias do not always result in statistically significant rejections this contrasts with most of the results reported in the literature which typically demonstrate sound rejections of unbiasedness our tests of rational expectations demonstrate significant irrationality in many but not all cases alternative explanations of the rejections focus on peso problems and learning about policy changes tests of perfect substitutability indicate the significant presence of time varying risk premia for all pairs of currencies studied and almost all horizons

expectation formation in the foreign exchange market a time varying heterogeneity approach using survey data using consensus economics survey data on jpy usd and gbp usd exchange rate expectations for the 3 and 12 month horizons over the period november 1989 december 2012 we first show that expectations fail the conventional tests of unbiasedness and do not exhibit a learning process towards rationality our approach is consistent with the economically rational expectations theory feige and pearce 1976 which states that information costs and agents aversion to misestimating future exchange rates determine the optimal amounts of information on which they base their expectations the time variability of the cost aversion ratios justifies at the aggregate level a representation of expectations as a linear combination of the traditional extrapolative adaptive and regressive processes augmented by a forward market component whose parameters are allowed to change over time this mixed expectation model with unstable heterogeneity is validated by our kalman filter estimation results for the two currencies and

tests of rational expectations and no risk premium in forward exchange markets abstract this paper tests the simple efficiency hypothesis i e that traders have rational expectations and charge no risk premium in the forward exchange market it uses a statistical procedure which is consistent under a large class of heteroscedasticity and a set of data which takes into account the institutional features of the forward exchange market the results show that this procedure leads to stronger rejections of the simple efficiency hypothesis than do procedures using the standard assumption of homoscedasticity

are capital controls in the foreign exchange market effective one of the reasons for governments to employ capital controls is to obtain some degree of monetary independence in this paper we test whether capital controls can reduce the link between exchange rates fluctuations and cross border interest differentials recent capital control proxies are used in order to determine the date of capital account liberalization for a panel of western european and emerging countries results show that capital controls have a very limited effect on observed deviations from interest parities even when accounting for the political risk associated with capital controls

forward foreign exchange rates expected spot rates and premia a signal extraction approach in this paper we implement a methodology to identify and measure premia in the pricing of forward foreign exchange that involves application of signal extraction techniques from the engineering literature diagnostic tests indicate that these methods are quite successful in capturing the essence of the time series properties of premium terms the estimated premium models indicate that premia show a certain degree of persistence over time and that more than half the variance in the forecast error that results from the use of current forward rates as predictors of future spot rates is accounted for by variation in premium terms the methodology can be applied straightforwardly to the measurement of unobservables in other financial markets there exists a growing body of empirical research on premia in the pricing of forward foreign exchange conditional on the hypothesis that the foreign exchange market is efficient or rational the existence of time varying premia has been documented in the literature by fama 6 hansen and hodrick 10 11 hodrick and srivastava 15 16 hsieh 171 and korajczyk 20 frankel 9 fails to identify such premia and domowitz and hakkio 51 obtain different results for different currencies

foreign exchange rate expectations micro survey data this paper analyzes the panel data of biweekly surveys on the yen dollar exchange rate expectations of forty four institutions for two years and contains four major findings first market participants are heterogeneous that is significant individual effects exist in their expectation formation second the individual effects have a characteristic of wishful expectations exporters expect yen depreciation and importers expect yen appreciation relative to others third many violate the rational expectations hypothesis fourth forecasts with long horizons show less yen appreciation than those with short horizons cross equation constraints implied by the consistency of the forecast term structure are strongly rejected in the data copyright 1990 by american economic association

testing the uncovered interest parity using traded volatility a time varying risk premium and heterogeneous expectations abstract this paper carries out an empirical investigation of an extended version of flood and marion s 2000 self fulfilling risk predictions an application to speculative attacks journal of international economics 50 245 268 uip model which incorporates a nonlinear time varying risk premium that depends on both the expected variance of the future exchange rate and the relative worldwide private holdings of domestic and foreign government bonds a novel contribution of our paper is the use of traded currency volatility which is directly observable in the market place to measure expectations about the future volatility of the exchange rate another contribution is the explicit modelling of heterogeneous exchange rate expectations formed by forward looking fundamentalists and backward looking chartists our overall empirical evidence provides strong support for the extended nonlinear uip model we also investigate for the first time the role of traded volatility in the dynamic behaviour of exchange rates and find that high currency volatility is likely to produce oscillatory and unstable exchange rate paths

carry trade and foreign exchange rate puzzles this article demonstrates that carry trade is part of the explanation of foreign exchange rate puzzles we introduce carry traders in a heterogeneous agent model in addition to fundamentalists and chartists our model has the ability to produce the stylized facts observed in empirical exchange rates such as heavy tails excess volatility and volatility clustering as well as the negative relationship between market volatility and carry trade activity we find that the interaction between carry traders and chartists provides an explanation for the forward premium puzzle this effect is strengthened by chartists who extrapolate the trend induced by carry trade

optimal hedging in a futures market with background noise and basis risk abstract this paper examines hedging behavior in an incomplete market in which there exists an unhedgeable and uninsurable independent background risk in the case of a basis risk that satisfies the regressibility property the background risk might be partly endogenous background risk generally has an ambiguous effect on the optimal hedge ratio however if preferences exhibit standard risk aversion and the background risk is fully exogenous the qualitative effect of the added background risk is determinate and depends on the direction of any bias in the futures market in all cases the speculative component of the hedge ratio is reduced in the presence of background risk when the background risk is a basis risk and futures prices exhibit normal backwardation this qualitative effect need not hold and it depends in part on the direction of regressability for spot and futures prices

time variation in term premia international survey based evidence using a large previously unexplored data set of survey based interest rate forecasts that covers a broad range of countries this paper re examines the expectations hypothesis of the term structure of interest rates we find that survey based interest rate forecasts outperform not only a random walk forecast but also outperform forecasts from forward rates when using these superior survey based forecasts in a modified expectations hypothesis test the expectations hypothesis is rejected for fewer countries at lower significance levels and has greater explanatory power than when using a traditional forward rates based test we furthermore document strong time variation in the term premia which is an important reason why the traditional expectations hypothesis test is rejected so frequently this time variation seems to arise from the changing attitudes towards risk among market participants and as a compensation for the change in liquidity in the term structure finally we find that generalizing findings from earlier u s studies to other countries may lead to bias in the true economic relationships in these countries

further evidence on exchange rate expectations abstract this paper considers a previously unexploited survey data set of exchange rate expectations which allows us to focus on differences between ems and dollar exchange rates we corroborate the earlier finding in the literature that exchange rate forecasts are not rational and that agents do not use all available information efficiently although extrapolative and adaptive expectations formation mechanisms describe non ems exchange rate expectations to a certain extent ems exchange rates forecasts seem to follow long run fundamentals more closely and would suggest that agents believe that ems exchange rate expectations undershoot their long run equilibrium values jel f31

on the effects of sterilized intervention an analysis of weekly data abstract as the recent empirical studies surveyed here illustrate it is very difficult to demonstrate that the exchange rate risk premium depends through a portfolio balance channel on the currency composition of outside assets the existence of a portfolio balance effect is a necessary condition for sterilized intervention to be a genuinely independent tool of monetary policy this paper studies u s canadian data and attempts to improve on earlier studies by using higher frequency weekly data and by implementing an appropriate instrumental variables technique 2s2sls however we still fail to detect evidence of a portfolio balance effect

recent estimates of time variation in the conditional variance and in the exchange risk premium abstract the optimal diversification model of investors portfolio behavior can give a linear relationship between the exchange risk premium and the conditional exchange rate variance this note surveys recent empirical work that allows the conditional variance itself and therefore the risk premium to vary over time in particular it examines the implications of recent empirical estimates for earlier arguments based on the assumption that the conditional variance was constant over time that the exchange risk premium had to be small in magnitude and variability

explaining dispersion in foreign exchange expectations a heterogeneous agent approach this paper combines survey forecasts with a heterogeneous agent model to examine the dispersion of expectations of participants in the foreign exchange market we find distinct variations in the level of dispersion and document that dispersion arises because of the combined effect of market participants holding private information and attaching different weights to fundamental technical and carry trade analyses we estimate a heterogeneous agent model on the survey forecasts and show that the weight attached to the three forecast rules is adjusted over time in response to the relative importance of the rules in the actual foreign exchange market the weights are related to market circumstances the switching model is finally shown to outperform the random walk model in an out of sample forecast exercise

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

an empirical examination of heterogeneity and switching in foreign exchange markets using a unique dataset of survey expectations this paper examines the extent to which the classical fundamentalist chartist dichotomy is valid for the foreign exchange market by applying a recursive selection algorithm 1 respondents are classified into the two groups and 2 the forecasting models are endogenously determined within the groups a large part of the variation in expectations can be explained by the fundamentalist chartist distinction switching however takes place between a naive and a sophisticated model that consists of both fundamentalist and chartist elements the sophisticated model is increasingly used as the forecast horizon increases

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
