The rapid growth of international reserves|a development concentrated in the emerging markets|remains a puzzle. In this paper we suggest that a model based on financial stability and financial openness goes far toward explaining reserve holdings in the modern era of globalized capital markets....

While the global financial crisis was centered in the United States, it led to a surprising appreciation in the dollar, suggesting global dollar illiquidity. In response, the Federal Reserve partnered with other central banks to inject dollars into the international financial system. Empirical...

We show that the when one takes into account the global equilibrium ramifications of an unwinding of the US current account deficit, currently running at more than 6% of GDP, the potential collapse of the dollar becomes considerably larger than our previous estimates (Obstfeld and Rogoff 2000a)...

This paper is structured in three parts. The first part outlines the methodological steps, involving both theoretical and empirical work, for assessing whether an observed allocation of resources across countries is efficient. The second part applies the methodology to the long-run allocation of...

This Paper explores the hypothesis that the dollarization of liabilities in emerging market economies is the result of a lack of monetary credibility. I present a model in which firms choose the currency composition of their debts so as to minimize their probability of default. Decreasing...

We study how credit supply shocks in the US, the euro area and Japan are transmitted to other economies. We use the recently-developed GVAR approach to model financial variables jointly with macroeconomic variables in 33 countries for the period 1983-2009. We experiment with inter-country links...

This Paper provides a comprehensive assessment of empirical evidence about the impact of financial globalization on growth and volatility in developing countries. The results suggest that it is difficult to establish a robust causal relationship between financial integration and economic growth....

The debate on EMU has been very influenced by the traditional theory of optimum currency areas (OCAs). The paper shows that this theory is not an ideal yardstick for an assessment of EMU. Its assumptions are not very realistic and its focus on asymmetric real shocks is much too narrow. In...

I use monthly data on industrial production to estimate the distribution of international business cycle correlations since the 1980's, with focus on the current turmoil. The degree of international correlation in national business cycles since the end of 2008 is unprecedented in three decades....

We present a simple model of sovereign debt crises in which a country chooses its optimal mix of short and long-term debt contracts subject to standard contracting frictions: the country cannot commit to repay its debts nor to a specific path of future debt issues, and contracts cannot be made...
