Milton Friedman argued that flexible exchange rates would facilitate external adjustment. Recent studies find surprisingly little robust evidence that they do. We argue that this is because they use composite (or aggregate) exchange rate regime classifications, which often mask very...

Why have emerging market economies (EMEs) been stockpiling international reserves? We find that motives have varied over time?vulnerability to current account shocks was relatively important in the 1980s but, as EMEs have become more financially integrated, factors related to the magnitude of...

This paper revisits the link between the nominal exchange rate regime and inflation, based on a sample of 145 emerging market and developing countries (EMDCs) over the period 1980-2010. We contend that, just as a de jure peg that is not backed by a de facto peg will have little value, de facto...

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 examines the spatial dispersion effects of regional conflicts, defined as internal or external armed conflicts in contiguous states, on international trade. Our empirical findings-based on different measures of conflict constructed using alternate definitions of contiguity and...

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 examines the role of the exchange rate regime in explaining how emerging market economies fared in the recent global financial crisis, particularly in terms of output losses and growth resilience. After controlling for regime switches during the crisis, using alternative definitions...

Bayesian Model Averaging (BMA) provides a coherent mechanism to address the problem of model uncertainty. In this paper we extend the BMA framework to panel data models where the lagged dependent variable as well as endogenous variables appear as regressors. We propose a Limited Information...

This paper explores and quantifies several aspects of the performance of currency unions using an augmented version of the gravity model and focusing on two samples, the world and Africa. Our empirical findings suggest that, in principle, membership in a currency union should benefit Africa as...

The paper investigates the existence of "super pro-poor" policies-that is, policies that directly influence the income of the poor after accounting for the effect of growth. It uses a dynamic panel estimator to capture both across- and within-country effects, and a Bayesian-type robustness check...
