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 reviews the main policy and analytical issues related to currency substitution in developing countries. The paper discusses, first, whether currency substitution should be encouraged or not; second, how the presence of currency substitution affects the choice of nominal anchors in inflation stabilization programs; third, the effects of changes in the rate of growth of the money supply on the real exchange rate; fourth, the interaction between inflationary finance and currency substitution; and, finally, issues related to the empirical verification of the currency substitution hypothesis.

The paper reviews recent theoretical and empirical developments in the analysis of informal currency markets in developing countries. The basic characteristics of these markets are highlighted, and alternative analytical models to explain them are discussed. The implications for exchange rate policy —including imposition of foreign exchange restrictions, devaluation, and unification of exchange markets— in countries with a sizable parallel market are also examined.

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.

This paper examines the relative demands for domestic and foreign currency deposits by residents of developing countries. A dynamic currency substitution model that incorporates forward-looking rational expectations is formulated and then estimated for a group of ten developing countries. The results indicate that the foreign rate of interest and the expected rate of depreciation of the parallel market exchange rate are important factors in the choice between holding domestic money or switching to foreign currency deposits held abroad. From an empirical standpoint, the forward-looking framework adopted here also turns out to be superior to the conventional currency-substitution model.

The politics surrounding exchange rate policies in the global economy The exchange rate is the most important price in any economy, since it affects all other prices. Exchange rates are set, either directly or indirectly, by government policy. Exchange rates are also central to the global economy, for they profoundly influence all international economic activity. Despite the critical role of exchange rate policy, there are few definitive explanations of why governments choose the currency policies they do. Filled with in-depth cases and examples, Currency Politics presents a comprehensive analysis of the politics surrounding exchange rates. Identifying the motivations for currency policy preferences on the part of industries seeking to influence politicians, Jeffry Frieden shows how each industry's characteristics—including its exposure to currency risk and the price effects of exchange rate movements—determine those preferences. Frieden evaluates the accuracy of his theoretical arguments in a variety of historical and geographical settings: he looks at the politics of the gold standard, particularly in the United States, and he examines the political economy of European monetary integration. He also analyzes the politics of Latin American currency policy over the past forty years, and focuses on the daunting currency crises that have frequently debilitated Latin American nations, including Mexico, Argentina, and Brazil. With an ambitious mix of narrative and statistical investigation, Currency Politics clarifies the political and economic determinants of exchange rate policies.

Guillermo Calvo, who foresaw the financial crisis that followed the devaluationn of Mexico's peso, has spent much of his career thinking beyond the conventional wisdom. In a quiet and understated way, Calvo has made seminal contributions to several major research areas in macroeconomics, particularly monetary policy, exchange rates, public debt, and stabilization in Latin America and post-communist countries. Money, Exchange Rates, and Output brings together these contributions in a broad selection of the author's work over the past two decades. There are introductions to each section, and an introduction to the entire collection that outlines the connections throughout and survey the current state of macroeconomic theory. Specific issues covered are predetermined exchange rates, currency substitution, domestic public debt and seigniorage, and stabilizing transition economics.

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.

Dollarization - the holding by residents of a substantial portion of their assets in foreign-currency-denominated assets- is a common feature of developing and transition economies, and therefore typical of many countries with IMF - supported adjustment programs. This paper analyzes policy issues that arise-and various monetary strategies that may be pursued- when the monetary sector is dollarized, and it considers the implications that dollarization has for the design of IMF programs.
