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 paper compares two approaches for examining the extent to which a country`s actual real effective exchange rate is consistent with economic fundamentals: the FEER approach, which involves calculating the real exchange rate that equates the current account at full employment with sustainable...

In this paper we extend the BEER (Behavioral Equilibrium Exchange Rate) approach which identifies an estimated equilibrium relationship between the real exchange rate and economic fundamentals. Here the economic fundamentals are decomposed using Johansen cointegration methods into transitory and...

A central puzzle in international finance is that real exchange rates are volatile and, in stark contradiction to effcient risk-sharing, negatively correlated with cross-country consumption ratios. This paper shows that incomplete asset markets and a low price elasticity of tradables can account...

A puzzle in international macroeconomics is that observed real exchange rates are highly volatile. Standard international real business cycle (IRBC) models cannot reproduce this fact. We show that total factor productivity processes for the United States and the rest of the world are...

Equilibrium exchange rate theories (FEER, BEER and NATREX) make the assumption that the Real Equilibrium Exchange Rate (RER) is independent from internal equilibrium and economic policies. We develop a model in which economic policies depend on the minimisation of an intertemporal loss function...

The business cycles of advanced economies are synchronized. Standard macro models fail to explain that fact. This paper presents a simple model of a two-country, two-traded good, complete-financial-markets world in which country-specific productivity shocks generate business cycles that are...
