This paper develops a cost-benefit approach that helps to quantify the optimal level of international reserves in low-income countries, focusing on the role of reserves in preventing and mitigating absorption drops triggered by large external shocks. The approach is applied to a sample of 49...

This paper examines why surges in capital flows to emerging market economies (EMEs) occur, and what determines the allocation of capital across countries during such surge episodes. We use two different methodologies to identify surges in EMEs over 1980-2009, differentiating between those mainly...

This paper presents a simple model of optimal reserves that can be easily calibrated to compute optimal reserves as well as the implied probability of a sudden stop for given reserves. The model builds upon the global games framework of Morris and Shin to establish a unique relationship between...

Low-income countries routinely experience exogenous disturbances—sharp swings in the terms of trade, export demand, natural disasters, and volatile financial flows—that contribute to higher volatility in aggregate output and consumption compared with other countries. Assessing Reserve...

This paper looks at the effects of International Monetary Fund (IMF) lending programs on banking crises in a large sample of developing countries, over the period 1970-2010. The endogeneity of the IMF intervention is addressed by adopting an instrumental variable strategy and a propensity score...
