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...

The workhorse open-economy macro model suggests that capital inflows are contractionary because they appreciate the currency and reduce net exports. Emerging market policy makers however believe that inflows lead to credit booms and rising output, and the evidence appears to go their way. To...

We examine whether macroprudential policies and capital controls can contribute to enhancing financial stability in the face of large capital inflows. We construct new indices of foreign currency (FX)-related prudential measures, domestic prudential measures, and financial-sector capital...

How high can public debt rise without compromising fiscal solvency? We answer this question using a stochastic ability-to-pay model of sovereign default in which risk-neutral investors lend to a government that displays "fiscal fatigue," because its ability to increase primary balances cannot...

This paper presents two approaches to modeling the use of IMF resources in order to gauge whether the recent decline in credit outstanding is a temporary or a permanent phenomenon. The two approaches - the time series behavior of credit outstanding and a two-stage program selection and access...

The paper considers gains from international economic policy coordination when there is uncertainty concerning the functioning of the world economy, but also learning about the quot;truequot; model on the part of policymakers. The paper reports estimates of plausible alternative versions of a...

This paper considers the design and desirability of rules for the international coordination of macroeconomic policies in a world characterized by model uncertainty. It is argued that the presence of model uncertainty, far from rendering cooperation unattractive, may actually provide a...

The relationship between current account developments and changes in the macroeconomic environment remains a key issue in open economy macroeconomics. This paper extends the standard intertemporal optimizing model of the current account to incorporate the effects of macroeconomic uncertainty on...

This paper considers the problem of allocation of investment for a debtor country that faces a ceiling on the amount of foreign debt it can accumulate. It shows that it is optimal for the debtor country to create a more open economy by favoring investment in the export sector over investment in...
