To what extent is the international business cycle affected by the fact that an essential input (oil) is traded on the world market? We quantify the contribution of oil by setting up a model with separate shocks to efficiencies of capital/labor and oil, as well as global shocks to the oil...

Existing empirical studies have focused on determinants of investment. We focus instead on episodes of accelerated capital stock growth that last eight years or longer. We find that episodes are relatively common, even in low growth regions, but more so in middle income and Asian countries....

This paper compares the depth of the Recent Crisis and the Great Depression. We use a new data set to compare the drop in activity in the industrialized countries for seven activity indicators. This is done under the assumption that the Recent Crisis leveled off in mid-2009 for production and...

In a panel covering a large number of countries from 1970 to 2003, we show that net portfolio flows play an important role in correcting external imbalances, since they are driven by common determinants represented by countries’ demographic profiles, the quality of institutions, monetary...

This paper reviews three different concepts of equilibrium exchange rates that are widely used in policy analysis and constitute the backbone of the IMF CGER assessment: the Macroeconomic Balance, the External Sustainability and the reduced form approaches. We raise a number of econometric...

The present paper extends the Obstfeld and Rogoff (2005) framework of current account imbalances by the oil exporting countries as a fourth region. It sets the stage for a variety of analysis that can be conducted within a four-region-setting that accounts for the importance of OPEC as a major...

this paper analyzes two effects which might have an important impact on a reduction of global external imbalances. These are valuation effects on the one hand and interest rate effects on the other hand. We use a four-region model that is based on the models by Obstfeld and Rogoff (2005) and...

Financial stability is an important policy objective, since crises are associated with large economic, social and political costs. Promoting stability requires preventing 'sudden stops' in capital flows, which are events in which foreign financing abruptly disappears. This paper contributes to...

Openness to trade is one factor that has been identified as determining whether a country is prone to sudden stops in capital inflows, crashes in currencies, or severe recessions. Some believe that openness raises vulnerability to foreign shocks, while others believe that it makes adjustment to...
