Uncertainty, Exchange Rate Regimes, and National Price Levels

Large differences in national price levels exist across countries. In this paper, I develop a general equilibrium model predicting that these differences should be related to countries' exchange rate regimes. My empirical findings confirm that countries with fixed exchange rate regimes have higher national price levels than countries with flexible regimes. At the disaggregate level, the relationship between exchange rate regimes and national price levels is stronger for nontraded goods than for traded goods. I also find that measuring the misalignment in national price levels around times of regime shifts without considering a break in its equilibrium value results in the overestimation of the true misalignment

How Strong is the Case for Dollarization in Central America? An Empirical Analysis of Business Cycles, Credit Market Imperfections and the Exchange Rate

In this paper, we contrast two different views in the debate on official dollarization. The Mundell (1961) framework of optimal currency areas and a model on boom-bust cycles, by Schneider and Tornell (2004), who take account of credit market imperfections prevalent in middle income countries. We highlight that the role of the exchange rate is strikingly different in the two models. While in the Mundell framework the exchange rate is expected to smooth the business cycle, the other model predicts that the exchange rate plays an amplifying role. We empirically evaluate both models for eight highly dollarized Central American economies, and find that the main benefit of official dollarization derives from avoiding a mismatch between foreign currency liabilities and domestic revenues, as well as the boom-bust episodes that are likely to follow from it. Using a new method of Cubadda (1999, 2007), we furthermore test for cyclical comovement and reject the hypothesis that the countries form an optimal currency area with the United States according to the Mundell definition

Inflation Targeting, Debt and the Brazilian Experience. 1999 to 2003

Inflation targeting -- when central bank policies set specific inflation rate objectives -- is widely used by both developed and developing countries around the world (although not by the United States or the European Central Bank). This collection of original essays looks at how Brazil's policy of inflation targeting, coupled with a floating exchange rate, survived a series of severe economic shocks and examines the policy lessons that can be drawn from Brazil's experience. After a successful start in early 1999, Brazil's policy regime had to manage mounting difficulties, including a sudden reversal of capital flows and its effects on the exchange rate and public debt, the contagion of Argentina's severe economic problems, a domestic energy crisis, and the political uncertainty of the 2002 presidential campaign. The contributors, prominent Brazilian and international economists, draw important lessons from Brazil's experience, including the necessity of accompanying monetary policy with fiscal improvement, the trade-offs involved in dollar-linked debt, the importance of fiscal institutions in an emerging market economy, and the importance of keeping inflation under control
