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)...

Over the past decade the US has experienced widening current account deficits and a steady deterioration of its net foreign asset position. During the second half of the 1990s, this deterioration was fuelled by foreign investment in a booming US stock market. During the first half of the 2000s,...

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 surveys the performance of international capital markets and the literature on measuring international capital mobility. Three main functions of a globally integrated and efficient world capital market provide focal points for the analysis. First, asset-price arbitrage ensures that...

This paper analyzes current stresses in the two key areas that concerned the architects of the original Bretton Woods system: international liquidity and exchange rate management. Despite radical changes since World War II in the market context for liquidity and exchange rate concerns, they...

The surge in international asset trade since the early 1990s has lead to renewed interest in models with international portfolio choice, an aspect that was largely cast aside when the ad-hoc portfolio balance models of the 1970s were replaced by models of optimizing agents. We develop the...

This paper studies the effects of demand and supply shocks in the global crude oil market on several measures of countries’ external balance, including the oil trade balance, the non-oil trade balance, the current account and changes in net foreign assets (NFA) during 1975–2004. We...

We analyse the impact of financial globalization on asset prices, investment and the possibility of crashes driven by self-fulfilling expectations in emerging markets. In a two-country model with one emerging market (intermediate income level) and one industrialized country (high income level),...
