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.
This paper examines the long-run determinants of the real exchange rate from a stock-flow perspective. The empirical analysis estimates a long-run relationship between the real exchange rate, net foreign assets and other factors affecting trade flows. Using postwar data for the United States and Japan, cointegration analysis supports the finding that the structural factors underlying each country’s net trade and net foreign asset positions determine the long-run path for the real value of the dollar and the yen. The empirical analysis also provides estimates for the underlying stochastic trend in each real exchange rate series.
Even though real exchange rate has an important impact on sustainable export and economic growth for small open economies, its impact on income distribution and transmission mechanism was never investigated. The paper shows that improved income distribution, through its impact on the price of nontradables, is associated with real exchange rate devaluation.
Trade liberalization in developing countries is frequently opposed on the grounds that, because it is likely to cause a deterioration in the external balance, it may not be a viable policy option for countries facing foreign exchange constraints. Recent literature suggests, however, an ambiguous relationship between tariff changes and the current account. This paper shows that if liberalization involves reducing tariffs on imported intermediate inputs (a reform that has figured prominently in developing countries), then the current account may improve or deteriorate, depending on the level of initial trade distortions and the structure of the economy.[JEL F13, F32, F41]
Using a simple dependent - economy framework, this paper outlines the links between the equilibrium real exchange rate and some of its fundamental exogenous determinants, mainly terms of trade movements and commercial policy changes. Drawing on existing studies of trade flows in developing countries, it is possible to derive plausible quantitative ranges for the response of the equilibrium real exchange rate to both external and policy-induced shocks. The results should be particularly relevant in designing real exchange rate targets and rules that allow for movements in the equilibrium real exchange rate in response to various shocks.
This paper investigates the likely implications of declining oil production on Yemen's equilibrium exchange rate, and discusses policy options to ensure a smooth transition to a nonoil economy. The empirical results suggest that, as oil production and foreign exchange earnings fall, the Yemeni rial will have to adjust downward in real effective terms to keep pace with the equilibrium exchange rate. In light of strong pass-through from exchange rate depreciation to domestic inflation, this could entail a substantial depreciation in nominal terms. Given the nature of the adjustment, a floating exchange rate regime appears to be the best option, if supported by appropriate macroeconomic policies. However, given public fixation on a exchange rate stability, a softly managed float would be a better option for Yemen whereby the central bank may have to lead the market toward the equilibrium exchange rate.
Although theory suggests that the real exchange rate should depreciate after a credible trade liberalization but could appreciate temporarily with a noncredible one, little empirical evidence exists. Unlike existing studies that use either indirect tests or unreliable openness measures, this paper uses an event study based on carefully documented trade liberalization in 45 countries. The result shows that real exchange rates depreciate after countries open their economies to trade. In countries with multiple liberalization episodes, however, real exchange rates appreciate during early episodes, suggesting that partial or noncredible trade liberalizations are associated with real appreciation.
Economists writing on flexible exchange rates in the 1960s foresaw neither the magnitude nor the persistence of the changes in real exchange rates that have occurred in the last fifteen years. Unexpectedly large movements in relative prices have lead to sharp changes in exports and imports, disrupting normal trading relations and causing shifts in employment and output. Many of the largest changes are not equilibrium adjustments to real disturbances but represent instead sustained departures from long-run equilibrium levels, with real exchange rates remaining "misaligned" for years at a time. Contributors to Misalignment of Exchange Rates address a series of questions about misalignment. Several papers investigate the causes of misalignment and the extent to which observed movements in real exchange rates can be attributed to misalignment. These studies are conducted both empirically, through the experiences of the United States, Great Britain, Japan, and the countries of the European Monetary System, and theoretically, through models of imperfect competition. Attention is then turned to the effects of misalignment, especially on employment and production, and to detailed estimates of the effects of changes in exchange rates on several industries, including the U.S. auto industry. In response to the contention that there is significant "hysteresis" in the adjustment of employment and production to changes in exchange rates, contributors also attempt to determine whether the effects of misalignment can be reversed once exchange rates return to earlier levels. Finally, the issue of how to avoid—or at least control—misalignment through macroeconomic policy is confronted.
This volume grew out of a National Bureau of Economic Research conference on exchange rates held in Bellagio, Italy, in 1982. In it, the world's most respected international monetary economists discuss three significant new views on the economics of exchange rates - Rudiger Dornbusch's overshooting model, Jacob Frenkel's and Michael Mussa's asset market variants, and Pentti Kouri's current account/portfolio approach. Their papers test these views with evidence from empirical studies and analyze a number of exchange rate policies in use today, including those of the European Monetary System.
