The reduction of global imbalances observed during the climax of crisis is incomplete. In this context, currencies' realignments are still proposed to ensure global macroeconomic stability. These realignments are based on equilibrium rates derived from equilibrium exchange rate models. Among...

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...

This study analyzes the dynamics between real effective exchange rates and current account patterns from a novel perspective. We start by dissecting long-run and time-varying short-run dynamics between both variables. Following this, we extend our framework by including interest rates into our...

This study analyzes the dynamics between real effective exchange rates and current accounts from a novel perspective. We start by dissecting long-run and time-varying short-run dynamics as well as causalities between both variables. Following this, we extend our framework by including short-term...

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 contrasts real exchange rate (RER) measures based on different deflators (CPI, GDP deflator, and ULC) and discusses potential implications for the link-or lack thereof-between RER and external balance. We begin by documenting patterns in the evolution of different measures of RERs,...
