A comprehensive and in-depth look at exchange-rate dynamics Variations in the foreign exchange market influence all aspects of the world economy, and understanding these dynamics is one of the great challenges of international economics. This book provides a new, comprehensive, and in-depth examination of the standard theories and latest research in exchange-rate economics. Covering a vast swath of theoretical and empirical work, the book explores established theories of exchange-rate determination using macroeconomic fundamentals, and presents unique microbased approaches that combine the insights of microstructure models with the macroeconomic forces driving currency trading. Macroeconomic models have long assumed that agents—households, firms, financial institutions, and central banks—all have the same information about the structure of the economy and therefore hold the same expectations and uncertainties regarding foreign currency returns. Microbased models, however, look at how heterogeneous information influences the trading decisions of agents and becomes embedded in exchange rates. Replicating key features of actual currency markets, these microbased models generate a rich array of empirical predictions concerning trading patterns and exchange-rate dynamics that are strongly supported by data. The models also show how changing macroeconomic conditions exert an influence on short-term exchange-rate dynamics via their impact on currency trading. Designed for graduate courses in international macroeconomics, international finance, and finance, and as a go-to reference for researchers in international economics, Exchange-Rate Dynamics guides readers through a range of literature on exchange-rate determination, offering fresh insights for further reading and research. Comprehensive and in-depth examination of the latest research in exchange-rate economics Outlines theoretical and empirical research across the spectrum of modeling approaches Presents new results on the importance of currency trading in exchange-rate determination Provides new perspectives on long-standing puzzles in exchange-rate economics End-of-chapter questions cement key ideas

Long-run movements of real exchange rates are studied using a panel data set comprising 51 economies. The purchasing power parity hypothesis (PPP) is examined first using unit root tests. It is found that PPP does not hold for the full sample of countries, but it may hold for the advanced economies, as well as open and high-inflation economies. Using the recently developed mean group and pooled mean group estimators, the paper finds support for the Balassa-Samuelson hypothesis in both advanced and developing economies; and for the influence of shifts in the terms of trade.

Interest rate expectations are essential for exchange rate determination. Using a unique Survey data set on interest rate forecasts from 1986 to 1995 for G7 countries, we find that interest rate shocks were significantly more persistent in sample than expected by the market. This is consistent with ff3's finding that changes in the forward rate reflect changes in exchange rate expectations. We then present a model of nominal exchange rate determination that rationalizes the forward discount puzzle and exhibits the delayed overshooting pattern found by ee: following a monetary expansion that reduces the domestic interest rate, there is a gradual depreciation of the exchange rate followed by a gradual appreciation several months later. Delayed overshooting results from (a) the interaction of learning about the current state of affairs, and the intrinsic dynamic response of interest rates to monetary shocks and (b) the discrepancy between the actual distribution of shocks in sample and its expectation by market participants. This discrepancy is consistent with rational expectations if either (a) there is a small sample or Peso problem or (b) the true structure of the economy evolves over time and agents are learning with some delay
