We provide new estimations on aggregate consumption series in France using the framework of non-stationary threshold models. Most macroeconomists agree with the idea that, since the beginning of the seventies, the saving ratio has evolved irregularly. Such irregularities are usually interpreted...

We revisit the evidence of the existence of a long-run link between financial intermediation and economic growth, by testing of cointegration between the growth rate of real GDP, control variables and three series reflecting financial intermediation. We consider a model with a factor structure...

This paper proposes a comparison of three nonlinear error-correction models to account for the asymmetric and slow adjustment dynamics of the Dollar-Sterling real exchange rate over a long period (1957-2002). We conclude that two NEC models adequately describe the nonlinear mean-reverting...

Do growth spells in Africa end because of bad realizations of the same factors that influence growth spells in the rest of the world, or because of different factors altogether? To answer this question, we examine determinants of growth spells in Africa and the rest of the world using Bayesian...

This paper provides an update on the main elements of the reform agenda concerning the CEMAC trade regime as well as a tentative quantitative assessment of selected effects on tariff revenues and trade patterns. Notwithstanding data limitations, the key messages from the analysis are as follows....

Exchange rate analysis lies at the center of the IMF's surveillance mandate and policy advice, as well as in the design of IMF-supported programs, and IMF staff are called upon to analyze a wide variety of exchange rate issues in various member countries, both small and large, from the least...

We propose a detailed Monte Carlo study of model selection criteria when the exact maximum likelihood (EML) method is used to estimate ARFIMA processes. More specifically, our object is to assess the performance of two automatic selection criteria in the presence of long-term memory: Akaike and...
