This paper examines whether decisions about the appropriate exchange rate regime in six Central American countries were based on longer-run economic fundamentals or on the confluence of historical and political circumstances. To uncover any actual relationship both across countries and across time, we estimate several probit and multinomial logit models of exchange rate regime choice with data spanning the period 1974-2001. We find that theoretical long-run determinants, such as trade openness, export share with the major trading partner, economic size, and per capita income, are adequate, but not robust, predictors of exchange rate regime choice. However, we were not able to establish a statistically significant association between the terms of trade fluctuations or capital account openness and a particular regime in any specification using our sample.

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.

''In summary, the book is valuable as a textbook both at the advanced undergraduate level and at the graduate level. It is also very useful for the economist who wants to be brought up-to-date on theoretical and empirical research on exchange rate behaviour.'' ""Journal of International Economics""

Standard models of policy credibility, defined as the expectation that an announced policy will be carried out, emphasize the preferences of the policymaker, and the role of tough policies in signalling toughness and raising credibility. Whether a policy is carried out, however, will also reflect the state of the economy. We present a model in which a policymaker maintains a fixed parity in good times, but devalues if the unemployment rate gets too high. Our main conclusion is that if there is persistence in unemployment, observing a tough policy in a given period may lower rather than raise the credibility of a no-devaluation pledge in subsequent periods. We test this implication on data for the interest rate differential between France and Germany and find support for our hypothesis.

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.

What guidance does academic research really provide to economic policy development? The critical and analytical surveys in this volume investigate links between policies and outcomes by surveying work from broad macroeconomic policies to interventions in microfinance. Asserting that there are no universal correspondences between policies and outcomes, contributors demonstrate instead that only an intense familiarity with the development context and the universe of applicable economic models can generate successful policies. Getting cause-and-effect right is essential for policy design and implementation. With the goal of drawing researchers and policy makers closer, this volume highlights our increasing understanding of ways to combine economic theorizing with careful, thoughtful empirical work. - Presents an accurate, self-contained survey of the current state of the field - Summarizes the most recent discussions, and elucidates new developments - Although original material is also included, the main aim is the provision of comprehensive and accessible surveys
