Аннотация:In this paper I discuss in what way, if any, the collapse of Argentina's experience with a currency board has affected the policy debate on the appropriate exchange rate regime in emerging and transition countries.More specifically, I deal with three issues: (1) I discuss some important aspects of the Argentine experience.(2) I provide a comparative evaluation of economic performance under strict dollarization.And (3), I analyze emerging countries' experiences with flexible exchange rates, including the issue of "fear of floating."
