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...

On January 1,1999 euro became the currency for 11 member states of the European Union. Since then the dollar-euro exchange rate has completed a full turning. Three years of depreciation of the euro followed by three years of appreciation without wild fluctuations asks for an explanation which...

Exchange rates as well as relative price level and output movements are decomposed into components associated with nominal shocks as well as shocks to aggregate supply and aggregate demand. In contrast to previous analyses of such decompositions based on statistical vector autoregression (VAR)...

We characterize the relationship between ex post exchange rate depreciation and the interest differential for a set of countries that spans both developed and emerging market economies. Measured ex post uncovered interest differentials are then related to measures of trade and financial...

We provide an overview of the recent developments of the literature on the determinants of long-term capital flows, global imbalances, and valuation effects. We present the main stylized facts of the new international financial landscape in which external balance sheets of countries have grown...

Exchange rates as well as relative price level and output movements are decomposed into components associated with nominal shocks as well as shocks to aggregate supply and aggregate demand. In contrast to previous analyses of such decompositions based on statistical vector autoregression (VAR)...

It is often argued that deregulation of international transactions and its effects on the globalization of financial markets is behind the decline in the attractiveness of fixed exchange rate regimes. We argue that, instead, much of the recently observed decrease in the level of capital controls...

This paper contributes to the debate on the magnitude of exchange rate elasticities by providing a set of price and quantity elasticities for 51 advanced and emerging-market economies. Specifically, for each of these countries we report the elasticity of trade prices and trade quantities on both...

This paper shows that there are two regularities in foreign exchange markets in advanced countries with flexible regimes. First, real exchange rates are mean-reverting, as implied by the Purchasing Power Parity model. Second, the adjustment takes place via nominal exchange rates. These features...
