We survey the empirical literature on floating nominal exchange rates over the past decade. Exchange rates are difficult to forecast at short- to medium-term horizons. There is a bit of explanatory power to monetary models such as the Dornbusch "overshooting " theory, in the form of reaction to "news " and in forecasts at long-mn horizons. Nevertheless, at short horizons, a driftless random walk characterizes exchange rates better than standard models based on observable macroeconomic fundamentals. Unexplained large shocks to floating rates must then, logically, be due either to innovations in unobservable fundamentals, or to non-fundamental factors such as speculative bubbles. The observed difference in exchange rate and macroeconomic volatility under different nominal exchange rate regimes makes us skeptical of the first view. The theory and evidence on speculative bubbles, however, is not conclusive. We conclude with the hope that promising new studies of the microstructure of the foreign exchange

Recent literature in empirical finance is surveyed in its relation to underlying behavioral principles, principles which come primarily from psychology, sociology and anthropology. The behavioral principles discussed are: prospect theory, regret and cognitive dissonance, anchoring, mental compartments, overconfidence, over- and underreaction, representativeness heuristic, the disjunction effect, gambling behavior and speculation, perceived irrelevance of history, magical thinking, quasi-magical thinking, attention anomalies, the availability heuristic, culture and social contagion, and global culture. Theories of human behavior from psychology, sociology, and anthropology have helped motivate much recent empirical research on the behavior of financial markets. In this paper I will survey both some of the most significant theories (for empirical finance) in these other social sciences and the empirical finance literature itself. Particular attention will be paid to the implications of these theories for the efficient markets hypothesis in finance. This is the hypothesis that financial prices efficiently incorporate all public

Abstract: The pass-through of exchange rate changes into domestic inflation appears to have declined in many countries since the 1980s. We develop a theoretical model that attributes the change in the rate of pass-through to increased emphasis on inflation stabilization by many central banks. This hypothesis is tested on twenty industrial countries between 1971 and 2003. We find widespread evidence of a robust and statistically significant link between estimated rates of pass-through and inflation variability. We also find evidence that observed monetary policy behavior may be a factor in the declining rate of pass-through.

To investigate how a fixed exchange rate affects monetary policy, this paper classifies countries as pegged or nonpegged and examines whether a pegged country must follow the interest rate changes in the base country. Despite recent research which hints that all countries, not just pegged countries, lack monetary freedom, the evidence shows that pegs follow base country interest rates more than nonpegs. This study uses actual behavior, not declared status, for regime classification; expands the sample including base currencies other than the dollar; examines the impact of capital controls, as well as other control variables; considers the time series properties of the data carefully; and uses cointegration and other levels-relationship analysis to provide additional insights.

We review the international finance literature to assess the extent to which international factors affect financial asset demands and prices. International asset pricing models with mean-variance investors predict that an asset’s risk premium depends on its covariance with the world market portfolio and, possibly, with exchange rate changes. The existing empirical evidence shows that a country’s risk premium depends on its covariance with the world market portfolio and that there is some evidence that exchange rate risk affects expected returns. However, the theoretical asset pricing literature relying on mean-variance optimizing investors fails in explaining the portfolio holdings of investors, equity flows, and the time-varying properties of correlations across countries. The home bias has the effect of increasing local influences on asset prices, while equity flows and cross-country correlations increase

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. Key Words: Foreign exchange rate; Expectations; Forward rate; and Efficient markets.

This paper presents a fully rational general equilibrium model that produces a timevarying exchange rate risk premium and solves the uncovered interest rate parity (U.I.P) puzzle. In this two-country model, agents are characterized by slow-moving external habit preferences derived from Campbell & Cochrane (1999). Endowment shocks are i.i.d and real risk-free rates are time-varying. Agents can trade across countries, but when a unit is shipped, only a fraction of the good arrives to the foreign shore. The model gives a rationale for the U.I.P puzzle: the domestic investor receives a positive exchange rate risk premium when she is more risk-averse than her foreign counterpart. Times of high riskaversion correspond to low interest rates. Thus, the domestic investor receives a positive risk premium when interest rates are lower at home than abroad. The model is both simulated and estimated. The simulation recovers the usual negative coefficient between exchange rate variations and interest rate differentials. When the iceberg-like trade cost is taken into account, the exchange rate variance produced is in line with its empirical counterpart. A nonlinear estimation of the model using consumption data leads to reasonable parameters when pricing the foreign excess returns of an American investor.

Aggregate consumption growth risk explains why low interest rate currencies do not appreciate as much as the interest rate differential and why high interest rate currencies do not depreciate as much as the interest rate differential. Domestic investors earn negative excess returns on low interest rate currency portfolios and positive excess returns on high interest rate currency portfolios. Because high interest rate currencies depreciate on average when domestic consumption growth is low and low interest rate currencies appreciate under the same conditions, low interest rate currencies provide domestic investors with a hedge against domestic aggregate consumption growth risk.
