We study determinants and consequences of sharp reductions in current account" imbalances (reversals) in low- and middle-income countries. We try to answer two questions:" first, what triggers reversals? Second, what factors explain how costly reversals are? We find" that both domestic...

Financially closed economies insure themselves against current-account shocks using international reserves. We characterize the optimal management of reserves using an open-economy model of precautionary savings and emphasize several results. First, the welfare-based opportunity cost of reserves...

The European Monetary Union is stuck in a severe balance-of-payments imbalance of a nature similar to the one that destroyed the Bretton Woods System. Greece, Ireland, Portugal, Spain and Italy have suffered from balance-of-payments deficits whose accumulated value, as measured by the Target...

A number of developing countries have run large and persistent current account deficits in both the late seventies/early eighties and in the early nineties, raising the issue of whether these persistent imbalances are sustainable. This paper puts forward a notion of current account...

This paper provides an empirical investigation of the medium-term determinants of current accounts for a large sample of industrial and developing countries. The analysis is based on a structural approach that highlights the roles of the fundamental macroeconomic determinants of saving and...

There has been a very rapid rise since the early 1990s in foreign reserves held by developing countries. These reserves have climbed to almost 30 percent of developing countries' GDP and 8 months of imports. Assuming reasonable spreads between the yield on reserve assets and the cost of foreign...

Based on a dataset of 112 emerging economies and developing countries, this paper addresses two key questions regarding the accumulation of international reserves: first, has the accumulation of reserves effectively protected countries during the 2008-09 financial crisis? And second, what...

This paper presents a model comparing the degree of asset class diversification abroad by a central bank and a sovereign wealth fund. We show that if the central bank manages its foreign asset holdings in order to meet balance of payments needs, particularly in reducing the probability of sudden...

The influential Krugman-Flood-Garber (KFG) model of balance of payment crises assumes that a fixed exchange rate is abandoned if and only if international reserves reach a critical threshold value. From a positive standpoint, the KFG rule is at odds with many episodes in which the central bank...
