We show the importance of a dynamic aggregation bias in accounting for the PPP puzzle. We prove that established time-series and panel methods substantially exaggerate the persistence of real exchange rates because of heterogeneity in the dynamics of disaggregated relative prices. When...

The forward premium is a notoriously poor predictor of exchange rate movements. This failure must reflect deviations from risk neutrality and/or rational expectations. In addition, a mechanism is needed that generates the appropriate correlation between the forward premium and shocks arising...

This paper reviews the experience with capital controls in industrial and developing countries, considers the policy issues raised when the effectiveness of capital controls diminishes, examines the medium-term benefits and costs of an open capital account, and analyzes the policy measures that...

This paper discusses the institutional arrangements for exchange rate targeting in Barbados and the critical role they played in the policy response to its balance of payments crisis of 1991-92. The framework featured ongoing cooperation between the central bank and the Ministry of Finance, and...

This study provides evidence that episodes of internal stability of exchange rates among the 11 Euro countries during 1957-98 were associated with periods of lower real commodity price volatility. These stabilizing effects are statistically significant for fertilizer, metals, petroleum, and...

We examine the implications of high degrees of dollarization for the choice of exchange rate regime and the information content of various monetary aggregates in developing countries. We conclude that a high degree of currency substitution argues for a more fixed exchange rate regime, while...

Using countries' de facto exchange rate regimes during 1985-2002, this paper analyzes the determinants of exits from pegged regimes, where exits involve shifts to more or less flexible regimes, or adjustments within the existing regime. Distinguishing episodes characterized by "exchange market...

The “hollowing-out,” or “two poles” hypothesis is tested in the context of a Markov chain model of exchange rate transitions. In particular, two versions of the hypothesis—that hard pegs are an absorbing state, or that fixes and floats form a closed set, with no transitions to...

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...

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...
