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...

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...

Since the 1997 Asian currency crisis, new interest has emerged in the formation of a common currency area in East Asia. This paper provides estimates of trade and welfare effects of East Asian currency unions, using a micro-founded gravity model. Counter-factual experiments to assess the effects...

This paper examines the role of Japan against that of China in the exchange rate regime in East Asia in light of growing interest in forming a currency union in the region. The analysis suggests that currency unions with China tend to generate higher average welfare gains for East Asian...

This paper develops a simple model of international lending, and calibrates it to assess quantitatively the effects of contingent IMF financial support on the risk premiums and the crisis probability. In the model, the country borrows in both short and long term; market (coordination) failure...

By using a simple intertemporal model of the current account, I show that the exchange rate elasticity of the trade balance would ceteris paribus be smaller for countries with higher government spending ratios (relative to GDP) and with more limited scope for private consumption smoothing. This...

In this note, the authors reexamine the issue of debt sustainability in a large group of advanced economies. Their hypothesis is that, when debt is in a moderate range, its dynamics are sustainable in the sense that increases in debt elicit sufficient increases in primary fiscal balances to...
