Understanding and predicting the evolution of exports after a change in the nominal exchange rate is of central importance in international economics. Most of the literature focuses on estimating this relationship by reduced form, with the aim of uncovering a single structural parameter, but...

The paper analyzes the sources of exchange rate movements in emerging economies in the context of monetary tapering by the Federal Reserve. A structural vector autoregression framework with a long-run restriction is used to decompose the movements of nominal ex-change rates into two components:...

This Selected Issues Paper and Statistical Appendix for Niger are discussed. The Nigerien economic outlook has been improving since 1999. After a long period of decline in per capita income, growth accelerated through 2007, attaining an annual average of 4 percent, or about 1 percent in per...

We reassess exchange rate prediction using a wider set of models that have been proposed in the last decade. The performance of these models is compared against two reference specifications-purchasing power parity and the sticky-price monetary model. The models are estimated in first-difference...

This paper focuses on assessments of real exchange rates using PPP data and examines their limitations when these are based exclusively on bivariate estimations. It begins by presenting an analytical framework of the real exchange rate that shows that these estimations make many restrictive...

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 papers estimates the equilibrium exchange rate for Armenia using three different approaches: the purchasing power parity (PPP) approach, the behavioral equilibrium exchange rate (BEER) approach, and the external sustainability (ES) approach. All three approaches suggest that the dram was...

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...

The paper describes six different methodologies that have been used to assess the equilibrium values of exchange rates and discusses their limitations. It applies several of the approaches to data for the United States as of 2006, illustrates that different approaches sometimes provide...
