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 presents a theoretical and empirical analysis of policies aimed at setting a more depreciated level of the real exchange rate. An intertemporal optimizing model suggests that, in the absence of changes in fiscal policy, a more depreciated level of the real exchange can only be attained temporarily. This can be achieved by means of higher inflation and/or higher real interest rates, depending on the degree of capital mobility. Evidence for Brazil, Chile, and Colombia supports the model’s prediction that undervalued real exchange rates are associated with higher inflation.

We show that the response of firm-level investment to real exchange rate movements varies depending on the production structure of the economy. Firms in advanced economies and in emerging Asia increase investment when the domestic currency weakens, in line with the traditional Mundell-Fleming model. However, in other emerging market and developing economies, as well as some advanced economies with a low degree of structural economic complexity, corporate investment increases when the domestic currency strengthens. This result is consistent with Diaz Alejandro (1963)—in economies where capital goods are mostly imported, a stronger real exchange rate reduces investment costs for domestic firms.

The study cautiously identifies exchange rate misalignment as an important element in most of the exchange rate crises that plagued the developing world during the last decade. Given that the increasing integration of world capital markets, has escalated the costs of such crises, a broad consensus emerged in recent years, that the overriding objective of exchange rate policy in developing countries, should be to avoid episodes of prolonged, and substantial misalignment, i.e., situations in which the actual real exchange rate differs significantly from its long-run equilibrium value. It was the Bank's involvement in one such misalignment episode, that eventually led to this book. Following an overview on the concepts and measurement of exchange rate misalignment, its impact on the purchasing power parity, and the relationship between the external real exchange rate (RER), and the two-good internal RER for tradables non-tradables, the study presents methodologies - empirical applications - for estimating the RER equilibrium. The study reaches an optimistic conclusion - that enough is known to identify cases of misalignment, and be able to sound clear warning signals. The implication for exchange rate policy is that ignorance about the empirical value of the equilibrium exchange rate, cannot be used to clinch arguments for extreme exchange arrangements, such as clean floats, currency boards, and "dollarization."

This paper provides a summary of the key policies that encourage dedollarization. It focuses on cases in which the authorities’ intention is to gain greater control of monetary policy and draws on the experiences of countries that have successfully dedollarized. Unlike previous work on the subject, this paper examines both macroeconomic stabilization policies and microeconomic measures, such as prudential regulation of the financial system. This study is also the first attempt to make extensive use of the foreign exchange regulation data reported in the IMF’s Annual Report on Exchange Arrangements and Exchange Restrictions. The main conclusion is that durable dedollarization depends on a credible disinflation plan and specific microeconomic measures.
