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 for 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.

The need for continued analysis and evaluation of the international financial system is as pressing now as it was when this book was originally published. This volume provides an in-depth analysis of certain aspects of the international financial system. Specifically it addresses four of the most important financial and monetary issues of the present time: exchange rate, capital markets, international banking and external debt and international financial management.

These seventeen essays provide an accessible and thorough reference for understanding the role of exchange rates in the international monetary system since 1973, when the rates were allowed to float. The essays analyze such issues as exchange rate movements, exchange risk premia, investor expectations of exchange rates and behavior of exchange rates in different systems. Frankel's sound empirical treatment of exchange rate questions shows that it is possible to produce work that is interesting from a purely intellectual viewpoint while contributing to practical knowledge of the real world of international economics and finance.The essays have been organized in a way that provides an introduction to the field of empirical international finance. Part I documents the steady reduction in barriers to international capital movement and leads logically to part II, which explains how exchange rates are determined. Both monetary and portfolio-based models are surveyed in part II, providing a clear transition to the topic of part III; the possible existence of an exchange risk premium. Part IV applies the tools discussed in earlier sections to explore various policy questions related to exchange rate expectations such as whether foreign exchange intervention matters and whether the European monetary system had become credible by 1991. Each part begins with a detailed introduction explaining not only the central issues of that section but also suggesting connections with other essays in the book.Jeffrey A. Frankel is Professor of Economics at the University of California, Berkeley.

The foreign exchange market is the largest, fastest-growing financial market in the world. Yet conventional macroeconomic approaches do not explain why people trade foreign exchange. At the same time, they fail to explain the short-run determinants of the exchange rate. These nine innovative essays use a microstructure approach to analyze the workings of the foreign exchange market, with special emphasis on institutional aspects and the actual behavior of market participants. They examine the volume of transactions, heterogeneity of traders, the time of day and location of trading, the bid-ask spread, and the high level of exchange rate volatility that has puzzled many observers. They also consider the structure of the market, including such issues as nontransparency, asymmetric information, liquidity trading, the use of automated brokers, the relationship between spot and derivative markets, and the importance of systemic risk in the market. This timely volume will be essential reading for anyone interested in the economics of international finance.

International Macroeconomic Dynamics provides extensive applications of important macroeconomic dynamic models to the international economy. For a long time, the study of macroeconomics has focused almost exclusively on a closed economy and downplayed the role of international transactions. Today, however, researchers recognize that one cannot fully understand domestic macroeconomic relationships without considering the global economy within which each country operates. Increasingly, economists are treating international transactions as an integral part of the macroeconomic system, and international macroeconomics has become an area of intensive research activity. International Macroeconomic Dynamics provides extensive applications of important macroeconomic dynamic models to the international economy. It adopts the main contemporary macroeconomic framework, the representative agent model, and develops a series of models of increasing complexity. The author considers both small and large economies and analyzes them in both deterministic and stochastic contexts. The emphasis is very much on the development of the analytical models; a novel feature is the extensive use of continuous-time stochastic methods. While the author applies the models to a range of important policy issues, particularly issues of fiscal policy, the reader is invited to view the analyses as blueprints for other applications.
