Macroeconomic models of nominal exchange rates perform poorly. In sample, R2 statistics as high as 10 percent are rare. Out of sample, these models are typically out-forecast by a na‹ve random walk. This paper presents a model of a new kind. Instead of relying exclusively on macroeconomic...

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 develops a method for joint estimation of both the degree of internal returns to scale and the extent of external economies. We apply the method in estimating returns to scale indexes for U.S. manufacturing industries at the two-digit level. Overall, we find that only three of the...

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...

We examine the trading strategies of mutual funds in emerging markets. We develop a method for disentangling the behavior of fund managers from that of underlying investors. For both managers and investors, we strongly reject the null hypothesis of no momentum trading: mutual funds...

How do mutual funds behave when they invest in emerging economies? For one thing, mutual funds' flows are not stable. Withdrawals from emerging markets during recent crises were large, which squares with existing evidence of financial contagion.International mutual funds are one of the main...

This study of an important class of investors-U.S. mutual funds-finds that mutual funds do engage in momentum trading (buying winners and selling losers). They also engage in contagion trading strategies (selling assets from one country when asset prices fall in another).Kaminsky, Lyons, and...

International mutual funds are key contributors to the globalization of financial markets and one of the main sources of capital flows to emerging economies. Despite their importance in emerging markets, little is known about their investment allocation and strategies. This paper provides an...

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...
