Real Exchange Rates, Devaluation, and Adjustment provides a unified theoretical and empirical investigation of exchange rate policy and performance in scores of developing countries. It develops a theory of equilibrium and disequilibrium real exchange rates, takes up the question of why devaluations are the most controversial policy measures in poorer nations, and discusses what determines their success or failure. In a lucid fashion, Edwards organizes vast amounts of data on exchange rates - both real and nominal - and discusses their effect on net trade balances, net asset positions, output growth, real wages, and rates of price inflation, analyzed both in time series and through cross country comparisons. Edwards's investigation singles out 39 major devaluation episodes for before and after comparative analyses while simultaneously isolating the separate effects of other important explanatory variables, such as bank credit expansion and changes in the terms of trade. The first part of the book focuses on theoretical models of devaluation and real exchange rate behavior in less developed countries. Special attention is paid to intertemporal channels in the transmission of disturbances. The second part uses a large cross country data set to analyze the way the real exchange rate has behaved in these nations. The data are also used to test the implications of several theories of real exchange rate determination. The third part analyzes actual devaluation experiences between 1962 and 1982. These chapters examine the events leading to a balance of payments crisis and to a devaluation, exploring the relation between macroeconomic disequilibrium, and the imposition of trade and exchange controls. They also investigate the effect of nominal devaluation on key variables such as the balance of payments, the current account, the real exchange rate, real output real wages, and income distribution.

Discusses economic issues associated with exchange rates, commodity prices, the economic size of countries and alternatives to PPP exchange rates.

Most trade is invoiced in very few currencies. Despite this, the Mundell-Fleming benchmark and its variants focus on pricing in the producer’s currency or in local currency. We model instead a ‘dominant currency paradigm’ for small open economies characterized by three features: pricing in a dominant currency; pricing complementarities, and imported input use in production. Under this paradigm: (a) the terms-of-trade is stable; (b) dominant currency exchange rate pass-through into export and import prices is high regardless of destination or origin of goods; (c) exchange rate pass-through of non-dominant currencies is small; (d) expenditure switching occurs mostly via imports, driven by the dollar exchange rate while exports respond weakly, if at all; (e) strengthening of the dominant currency relative to non-dominant ones can negatively impact global trade; (f) optimal monetary policy targets deviations from the law of one price arising from dominant currency fluctuations, in addition to the inflation and output gap. Using data from Colombia we document strong support for the dominant currency paradigm.

The book provides a hands-on introduction to computable general equilibrium (CGE) models, written at an accessible, undergraduate level.

This article analyzes the theory of equilibrium real exchange rates and defines misalignment as a deviation of the real exchange rate (RER) from its equilibrium level. The role of macroeconomic policies is then analyzed under three alternative nominal exchange rate regimes: predetermined nominal exchange rates; floating nominal rates; and dual or black market nominal exchange rates. This discussion points out how inconsistent macroeconomic policies often lead to real exchange rate misalignment. Corrective measures, including nominal devaluation and several alternative approaches, are then evaluated.

We compile a historical dataset covering nearly 40 years of booms and busts in the commodity terms of trade of over 150 countries. We discuss the characteristics of these events and their effects on macroeconomic performance and, in particular, compare the most recent commodity-price cycle with its historical precedents.
