The recent collapse of the Argentine currency board raises new questions about the desirability of formal fixed exchange rate regimes in modern developing economies. This paper examines the impact of dollarized liabilities with potential default for a currency board with costly abandonment. We...

How should monetary policy be optimally designed in an environment with high degrees of financial globalization? To answer this question we lay down an open economy model where net lending toward the rest of the world is constrained by a collateral constraint motivated by limited enforcement....

Monetary policy instruments differ in tightness - how closely they are linked to inflation - and transparency - how easily they can be monitored. Tightness is always desirable in a monetary policy instrument; when is transparency? When a government cannot commit to follow a given policy. We...
