Consensus estimates put the half-life of deviations from purchasing power parity (PPP) at about four years (Rogoff, 1996). However, conventional least squares estimates of half-lives are biased downward. Accordingly, as a preferred measure of the persistence of real exchange rate shocks, this...

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...

This data module of the Report on the Observance of Standards and Codes (ROSC) provides a summary assessment of dissemination practices in the Philippines relative to the Special Data Dissemination Standard (SDDS). It presents a summary assessment of data quality for national accounts, consumer...

We propose using a Bayesian time-varying coefficient model estimated with Markov chain-Monte Carlo methods to measure contagion empirically. The proposed measure works in the joint presence of heteroskedasticity and omitted variables and does not require knowledge of the timing of the crisis. It...

We apply the fundamentals equilibrium exchange rate (FEER) approach and the Johansen cointegration methodology to investigate the behavior of the real effective exchange rates of the two monetary unions of the CFA franc zone (CEMAC and WAEMU) vis-à-vis their long-run equilibrium paths. For both...

Current estimates of global poverty vary substantially across studies. In this paper we undertake a novel sensitivity analysis to highlight the importance of methodological choices in estimating global poverty. We measure global poverty using different data sources, parametric and nonparametric...

This paper presents two approaches to modeling the use of IMF resources in order to gauge whether the recent decline in credit outstanding is a temporary or a permanent phenomenon. The two approaches-the time series behavior of credit outstanding and a two-stage program selection and access...

This paper has examined the phenomenon of convergence of per capita output levels across regions of Bangladesh during 1982–97. The main finding is that most of the regions of Bangladesh experienced strong convergence of per capita output levels during 1982–91. There are two other findings...

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...
