The objective of this paper is to analyze the relationship between exchange rate regime, capital account convertibility and economic growth in 1990-2007 period within the emerging countries that constitute what has been called BRIC - Brazil, Russia, India and China. Our hypothesis is that economic performance of these countries is the result, at least partially, of the quality of the macroeconomic policy management adopted in each country, in which exchange rate policy, capital account convertibility and the degree of external vulnerability plays a key role.
