This paper examines three different explanations of the global financial imbalances. It begins with the neoliberal globalization hypothesis that explains the imbalances as the product of the model of globalization implemented over the past thirty years. It then examines the saving glut and...

We analyze the global imbalances and the required adjustments for rebalancing in current accounts and real exchange rates. We set up a two-country two-sector model for the US-China with two asymmetries. First, we assume that the size of China initially is one third of the US but its size becomes...

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...

This study divides the world into currency zones according to the co-movement of each currency with the key currencies. The dollar zone groups economies that produce well over half of global GDP. The euro zone now includes almost all of Europe and some commodity producers, but remains less than...

There are two main forces behind the large U.S. current account deficits. First, an increase in the U.S. demand for foreign goods. Second, an increase in the foreign demand for U.S. assets. Both forces have contributed to steadily increasing current account deficits since the mid-1990s. This...

The influential work of Obstfeld and Rogoff argues that a closing-up of the US current account deficit involves a large exchange rate adjustment. However, the Obstfeld-Rogoff model works exclusively via demand-side channels and abstracts from possible supply-side changes. We extend the framework...

Since the late-1990s, the global economy is characterised by historically low risk premia and an unprecedented widening of external imbalances. This paper explores to what extent these two global trends can be understood as a reaction to three structural shocks in different regions of the global...

This paper examines two competing approaches for calculating current account benchmarks, i.e. the external sustainability approach á la Lane and Milesi-Ferretti (LM) versus the structural current accounts literature (SCA) based on panel econometric techniques. The aim is to gauge the medium...

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...
