This paper provides a selective overview of nonlinear exchange rate models recently proposed in the literature and assesses their contribution to understanding exchange rate behavior. Two key questions are examined. The first question is whether nonlinear autoregressive models of real exchange...

This study establishes a framework for analyzing the major determinants of inflation in the Islamic Republic of Iran. An empirical model was estimated by taking into consideration disequilibria in the markets for money, foreign exchange, and goods. Results strongly support the need for a...

Univariate studies of the hypothesis of unit roots in real exchange rates have yielded consensus point estimates of the half-life of deviations from purchasing power parity of between three to five years. However, least squares-based estimates of half-lives are biased downward. Accordingly, we...

This paper examines whether the real exchange rates of commodity-exporting countries and the real prices of their commodity exports move together over time. Using IMF data on the world prices of 44 commodities and national commodity export shares, we construct new monthly indices of national...

Relative GDP shares are frequently used as weights in aggregations. In order to ensure that these weights reflect countries’ shares in real output, GDP data in national currencies should be converted into a common numeraire currency at purchasing power parity (PPP) rates. A review of the...

The weakness of the euro has been surprising given the widely-held expectation that it would be a strong currency. This paper critically examines explanations for the slide in the euro, finding that many are questionable on conceptual or empirical grounds. Two explanations are instead advanced...

In the last two years the real has undergone a large depreciation and the central bank has missed its inflation target in 2002 for the second year in a row. Inflation, however, has increased much less than the rate of currency depreciation and the pickup in inflation in the last quarter of 2002...

This paper develops stylized facts about the inflation process in developing countries, focusing particularly on the relationship between the exchange rate regime and the sources of inflation. Using annual data from 1964 to 1998 for 53 developing countries, we find that money growth and exchange...

Over the past decade or so, Tunisia has experienced a strong economic performance while pursuing a constant real exchange rate rule (CRERR). The limitations of this rule are now beginning to emerge in the context of a more open economy, regional integration, a more market-based monetary policy,...

This paper offers an in-depth review of the institutional arrangements underlying existing currency boards (CBAs) in Argentina (until 2001), Eastern Europe, and Asia. An index of precommitment is derived from an analysis of legislative frameworks and monetary policy operations. The index covers...
