Arghyrou, Gregoriou and Pourpourides (2009) argue that exchange rate uncertainty causes deviations from the law of one price. We test this hypothesis on aggregate data from the G7-area. We find that exchange rate uncertainty explains to a significant degree deviations from Purchasing Power Parity.

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...

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...

In emerging-market economies, real exchange rate adjustment is critical for maintaining a sustainable current account position and thereby for helping to reduce macroeconomic and financial instability. The authors examine empirically two related hypotheses: (i) that real exchange rate...

This paper studies how removing barriers to competition in the nontraded goods sector affects the current account, the real exchange rate, and factor prices in a small open economy. We show that the expansion of the nontraded sector that results from a "deregulation shock" is associated with an...

We use a dynamic general-equilibrium model to study how removing barriers to competition in the nontraded goods sector affects the current account of a small open economy. We show that the expansion of the nontraded sector that results from such a "deregulation shock" is associated with an...

The paper's objective is to examine whether the Indian Rupee was fairly valued as of end March 2015. First, the movements of the trade weighted real effective exchange rate (REER) of the Rupee are tracked over the last ten years. Next, the underpinnings of the Harrod-Balassa-Samuelson effect,...

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...

This paper re-examines the role of real supply shocks in international business cycles. In contrast to previous studies, we extend the concept of supply shocks beyond the productivity shock towards labor supply shocks. Our analysis simultaneously identifies five real and nominal disturbances in...
