This paper considers the general equilibrium relationship between exchange rates and global imbalances. It emphasizes that the exchange rate is not a primitive but an equilibrium price determined by the policy mix. It uses extensions of the two-country Obstfeld-Rogoff model to analyze the...

In theory, nominal exchange rate movements can lead to 'expenditure switching' when they generate changes in the relative prices of goods across countries. This paper explores whether the expenditure-switching role of exchange rates has changed in the current episode of significant global...

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...

This paper analyzes the causes and implications of recent financial crises. Financial crises in general lead to changes in both theory and practice of economics. The paper takes an historical overview. The global consensus of economic theory during the 20th century is discussed. The paper...

Orthodox and heterodox theories of financial crises are hereby compared from a theoretical viewpoint, with emphasis on their genesis. The former view (represented by the fourth generation models of Paul Krugman) reflects the neoclassical vision whereby turbulence is an exception; the latter...

The IMF began to play a prominent role in low-income countries in the late 1970s and 1980s when many countries faced overvalued exchange rates, growing budget deficits, high inflation, and low reserves. But times have changed, and many low-income countries no longer face these problems and do...

Most economies experience episodes of persistent real exchange rate appreciations, when the question arises whether there is a need for intervention to protect the export sector. In this paper we present a model of irreversible destruction where exchange rate intervention may be justified if the...
