We find important differences in dollar-based and dollar-neutral G10 carry trades. Dollar-neutral trades have positive average returns, are highly negatively skewed, are correlated with risk factors, and exhibit considerable downside risk. In contrast, a diversified dollar-carry portfolio has a higher average excess return, a higher Sharpe ratio, m...

Investigations of the basic risk-return trade-off for the market return typically use maximum likelihood estimation (MLE) with a monthly or quarterly horizon and data sampled to match the horizon even though daily data are available. We develop an overlapping data inference methodology for such models that uses all of the data while maintaining the...

We examine carry trade returns formed from the G10 currencies. Performance attributes depend on the base currency. Dynamically spread-weighting and risk-rebalancing positions improves performance. Equity, bond, FX, volatility, and downside equity risks cannot explain profitability. Dollar-neutral carry trades exhibit insignificant abnormal returns,...

Asset pricing models such as the conditional CAPM are typically estimated with MLE using a monthly or quarterly horizon with data sampled to match the horizon even though daily data are available. We develop an overlapping data inference methodology (ODIN) that uses all of the data while maintaining the monthly or quarterly forecasting period, and...

The goal of this paper is to show that the growth rate of the Baltic Dry Index (BDI) has predictive ability for a range of stock markets, which is demonstrated through in-sample tests and out-of-sample statistics. The documented stock return predictability is also of economic significance, as seen by examining the certainty equivalent returns and S...

We examine aggregate idiosyncratic volatility in 23 developed equity markets, measured using various methodologies, and we find no evidence of upward trends. Instead, idiosyncratic volatility appears to be well described by a stationary autoregressive process that occasionally switches into a higher-variance regime that has relatively short duratio...

International diversification has costs and benefits, depending on the degree of asset dependence. In light of theoretical research linking diversification and dependence, we examine international diversification with two dependence measures: correlations and extreme dependence. We document several findings. First, dependence has generally increase...

We examine international stock return comovements using country-industry and country-style portfolios as the base portfolios. We first establish that parsimonious risk-based factor models capture the data covariance structure better than the popular Heston-Rouwenhorst (1994) model. We then establish the following stylized facts regarding stock retu...

Stocks with recent past high idiosyncratic volatility have low future average returns around the world. Across 23 developed markets, the difference in average returns between the extreme quintile portfolios sorted on idiosyncratic volatility is -1.31% per month, after controlling for world market, size, and value factors. The effect is individually...

Abstract We examine idiosyncratic volatility in 23 developed equity markets, measured using various alternative methodologies, and find no evidence that it is trending upward. Instead, idiosyncratic volatility appears,to be well described,by a stationary,autoregressive,process,that occasionally switches into a higher-variance regime,that has relati...

We examine the pricing of aggregate volatility risk in the cross-section of stock returns. Consistent with theory, we find that stocks with high sensitivities to innovations in aggregate volatility have low average returns. Stocks with high idiosyncratic volatility relative to the Fama and French (1993, "Journal of Financial Economics" 25, 2349) mo...

We investigate the ability of several international asset pricing models to price the returns on 36 FTSE global industry portfolios. The models are the international capital asset pricing model (ICAPM) the ICAPM with exchange risks, and global two-factor and three-factor Fama-French (1996, 1998) models. We apply the methodology of Hansen and Jagann...

This paper examines characterizations of the dynamics for the first and second moments of the one-month interest rate, the 12-month excess bond return and exchange rates. The countries considered are the US, Germany, Japan, and the UK. Our tests are based on the implications of multi-country versions of the Cox et al. (1985) class of term structure...

We investigate the expectations hypotheses of the term structure of interest rates and of the foreign exchange market using vector autoregressive methods for U.S. dollar, Deutsche mark, and British pound interest rates and exchange rates. We examine Wald, Lagrange multiplier, and distance metric tests by iterating on approximate solutions that requ...

This paper evaluates the specification errors of several empirical asset pricing models that have been developed as potential improvements on the CAPM. We use the methodology of Hansen and Jagannathan (J. Finance 51 (1997) 3), and the test assets are the 25 Fama-French (J. Financial Econom. 52 (1997) 557) equity portfolios sorted on size and book-t...

This paper examines characterizations of exchange rate and short-term interest rate dynamics, based on the implications of multi-country versions of the Cox, Ingersoll, and Ross (1985) class of term structure models. The countries considered are the US, Germany, Japan, and the UK. Our tests reveal that multi-country models are, in some cases, bette...

Many have questioned the empirical relevance of the Calvo-Yun model. This paper adds a term structure to three widely studied macroeconomic models (Calvo-Yun, hybrid and Svensson). We back out from observations on the yield curve the underlying macroeconomic model that most closely matches the level, slope and curvature of the yield curve. With eac...

We investigate whether term structure anomalies in U.S. data may be due to a generalized peso problem, in which a high-interest-rate regime occurred less frequently in the U.S. sample than was rationally anticipated. We formalize this idea by estimating a regime-switching model of short-term interest rates with data from seven countries. Under the...

We examine the ability of a dynamic asset-pricing model to explain the returns on G7-country stock market indices. We extend Campbell's (1996) asset-pricing model to investigate international equity returns. We also utilize and evaluate recent evidence on the predictability of stock returns. We find some evidence for the role of hedging demands in...

The authors propose a procedure for representing a time series of a smoothly varying trend component and a cyclical component. They document the nature of the comovements of the cyclical components of a variety of macroeconomic time series. The authors find that comovements are very different than the corresponding comovements of the slowly varying...

We document extreme bias and dispersion in the small sample distributions of five standard regression tests of the expectations hypothesis of the term structure of interest rates. These biases derive from the extreme persistence in short interest rates. We derive approximate analytic expressions for these biases, and we characterize the small-sampl...

We back out from observations on the yield curve the underlying macroeconomic model that most closely matches the level, slope and curvature of the yield curve. With eac...

In an effort to explain simultaneously the excess return predictability observed in equity, bond and foreign exchange markets, we incorporate preferences exhibiting first-order risk aversion into a general equilibrium two-country monetary model. When we calibrate the model to US and Japanese data, we find that first-order risk aversion substantiall...

This paper provides a selective survey of the voluminous literature on tests for market efficiency. The ideas discussed include standard autocorrelation tests, multi-period regression tests and volatility tests. The formulation and estimation of models for time-varying volatility are also considered. Dependence in second-order moments plays an impo...

This paper first characterizes the predictable components in excess rates of returns on major equity and foreign-exchange markets using lagged excess returns, dividend yields, and forward premiums as instruments. Vector autoregressions demonstrate one-step-ahead predictability and facilitate calculations of implied long-horizon statistics, such as...

Alternative ways of conducting inference and measurement for long-horizon forecasting are explored with an application to dividend yields as predictors of stock returns. Monte Carlo analysis indicates that the L. Hansen and R. Hodrick (1980) procedure is biased at long horizons, but the alternatives perform better. These include an estimator derive...

The hypothesis that the forward rate is an unbiased predictor of the future spot rate has been consistently rejected in recent empirical studies. This paper examines several sources of measurement error and misspecification that might induce biases in such studies. Although previous inferences are shown to be robust to a failure to construct true r...

Monetary models based on cash-in-advance constraints make strong predictions about the stochastic properties of endogenous variables such as the velocity of circulation of money, the rate of inflation, and real and nominal interest rates. The authors develop numerical methods to understand these predictions because the models cannot be characterize...

Monte Carlo analysis indicates that the Hansen and Hodrick (1980) procedure is biased at long horizons, but the alternatives perform better. These include an estimator derived unde...

I he possibility that movements in prices could be due to the self-fulfilling prophecies of market participants has long intrigued observers of free mar- kets. Such self-fulfilling prophecies are often called "bubbles" or "sunspots" to denote their dependence on events that are extraneous to the market. The folklore of such episodes includes the tu...

Early cash-in-advance models have the feature that the cash-in-advance constraint always binds, implying that the velocity of money is constant. Lucas (1984) and Svensson (1985) propose a change in information structure that potentially allows velocity to vary. By calibrating a version of these models using a new solution algorithm, and using U.S....

This paper examines several aspects of the debate about the causes of the U.S. current account deficit in the 1980's. It surveys several popular explanations before developing two theoretical models of international capital flows. The first model is Ricardian, and it extends the analysis of Stockman and Svensson (1987): The second model is an overl...

This paper explores a new direction for empirical models of exchange rate determination. The motivation arises from two well documented facts, the failure of log-linear empirical exchange rate models of the 1970's and the variability of risk premiums in the forward market. Rational maximizing models of economic behavior imply that changes in the co...

"Nowhere does history indulge in repetitions so often or so uniformly as in Wall Street," observed legendary speculator Jesse Livermore. History tells us that periods of major technological innovation are typically accompanied by speculative bubbles as economic agents overreact to genuine advancements in productivity. Excessive run-ups in asset pri...

The theoretical nature of risk premiums in foreign currency futures markets is derived and studied empirically. Estimation problems encountered in using futures data are discussed. Since forward rates and futures prices are demonstrated to be approximately equal, and because risk premiums in forward markets are highly variable, consistency of the d...

Several recent studies have attributed a large part of asset price volatility to self-fulfilling expectations. Such an explanation is unattractive to many since it allows allocations that need bear no particular relation to those implied by the economist's standard kit of market fundamentals. We examine the evidence presented in some of these studi...

This paper develops an open-economy model of the business cycle. The nominal prices in the model are flexible and monetary nonneutrality is developed using information confusion about the sources of disturbances to demand coupled with differential persistence of demand shocks. Firms use inventories to smooth their production, and consumers follow a...

Evidence of excess volatilities of asset prices compared with those of market fundamentals is often attributed to speculative bubbles. This study examines the sense in which speculative bubbles could in theory lead to excess volatility, hut it demonstrates that some of the variance hounds evidence reported to date precludes bubbles as a reason why...

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 confirm his findings. In contrast to his interpretation the results are not necessarily at variance with the predictions...

Typical evaluations of the choice of exchange rate regime examine the performance of the real economy and assume that the regimes last indefinitely. In contrast, actual regimes are quite transitory. This paper examines how the predictions of two popular models for the determination of some real economic variables must be modified when agents ration...

These twelve essays take up economic management under flexible exchange rates in the presence of uncertainty. Nearly all of the contributions adopt a rational expectations framework, focusing on the stochastic aspects of the assumption and exploring the variability of, for example, output and prices in relation to the variability of various externa...

This paper presents a macroeconomic model containing optimizing, inventory-holding firms that is consistent with a number of prominent empirical regularities concerning fluctuations in output, exchange rates, relative prices, and money. Prices are sticky, but they are not predetermined. Still, our model is consistent with exchange rate overshooting...

This paper examines the determination of risk premiums in foreign exchange markets. The statistical model is based on a theoretical model of asset pricing, which leads to severe cross-equation constraints. Statistical tests lead to a rejection of these constraints. We examine the robustness of these tests to time variation in parameters and to the...

This paper investigates the real effects of announced or perfectly foreseen changes in monetary policy produced by the Mundell-Tobin effect. A particularly good place to study these non-neutralities appears to be the period between announcement and implementation of new policies. At announcement the economy jumps to a new equilibrium path moving co...

This paper investigates the effects of government policies in a small open economy. Determination of the exchange rate and the effects of macroeconomic policies on the balance-of-payments accounts are examined in a model of infinitely lived, utility-maximizing agents who have perfect foresight. Residents of the country and the government borrow and...

This paper formulates a model of a small open economy which has perfect foresight about the future course of financial policies and their consequences. The authorities' expenditures must satisfy a budget constraint, and the private sector discounts future tax liabilities implied by government borrowing. Further assumptions are that there is perfect...

Recent empirical evidence that forward exchange rates are biased predictors of future spot rates can also be interpreted as evidence against the hypothesis of a constant risk premium. Consequently, reconciliation of this evidence with efficient international capital markets requires the existence of time-varying risk premia. This paper modifies Kou...

We propose a procedure for representing a time series as the sum of a smoothly varying trend component and a cyclical component. We document the nature of the co-movements of the cyclical components of a variety of macroeconomic time series. We find that these co-movements are very different than the corresponding co-movements of the slowly varying...

This paper examines the hypothesis that the expected rate of return to speculation in the forward foreign exchange market is zero; that is, the logarithm of the forward exchange rate is the market's conditional expectation of the logarithm of the future spot rate. A new computationally tractable econometric methodology for examining restrictions on...

The effects of three government policies, an increase in the provision of government services, an open market operation, and an increase in the rate of growth of government liabilities, are studied in a long-run model of a small open economy with flexible exchange rates. The government budget constraint, the degree to which government bonds are net...
