Foreign exchange returns exhibit behavior difficult to reconcile with standard theoretical models. This paper asks whether the recent findings of long swings in exchange rates between appreciating and depreciating periods affect estimates of the foreign exchange risk premium. We demonstrate how...

Recent empirical studies suggest that nominal interest rates and expected inflation do not move together one for one in the long run, a finding at odds with many theoretical models. This paper shows that these results can be deceptive when the process followed by inflation shifts infrequently....

We address the exchange rate determination puzzle by examining how information is aggregated in a dynamic general equilibrium (DGE) setting. Unlike other DGE macro models, which enrich either preference structures or production structures, our model enriches the information structure. The model...

This paper tests the portfolio-balance approach to exchange rate determination in a new way. Past work on portfolio balance in foreign exchange falls into two groups: (1) tests using measures of asset supply and (2) tests using measures of central-bank asset demand. We address the demand side,...

This paper provides new perspective on the poor performance of exchange rate models by focusing on the information structure of FX trading. I present a new theoretical model of FX trading that emphasizes the role of incomplete and heterogeneous information. The model shows how an equilibrium...

Macroeconomic models of nominal exchange rates perform poorly. The propor-tion of monthly exchange rate changes that these models can explain is essen-tially zero. This paper presents a model of a new kind. Instead of relying exclu-sively on macroeconomic determinants, the model includes a...

This paper examines the extent to which swings in stock prices can be related to variations in the discounted value of expected future dividends when investors face uncertainty about their future behavior. First, I present evidence of instability in time series behavior of dividends and discount...

This paper addresses whether macro news arrivals affect currency markets over time. The null from macro exchange-rate theory is that they do not: macro news is impounded in exchange rates instantaneously. We test this by examining the effects of news on subsequent trades by end-user participants...

I examine the sources of exchange rate dynamics by focusing on the information structure of FX trading. This structure permits the existence of an equilibrium distribution of transaction prices at a point in time. I develop and estimate a model of the price distribution using data from the...

This paper presents an exchange rate model of a new kind. Instead of relying exclusively on macroeconomic determinants, the model includes a determinant from the field of microstructure finance - order flow. Order flow is a determinant because it conveys information. This is a radically...
