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...

We characterize the relationship between ex post exchange rate depreciation and the interest differential for a set of countries that spans both developed and emerging market economies. Measured ex post uncovered interest differentials are then related to measures of trade and financial...

This paper contributes to the debate on the magnitude of exchange rate elasticities by providing a set of price and quantity elasticities for 51 advanced and emerging-market economies. Specifically, for each of these countries we report the elasticity of trade prices and trade quantities on both...

This paper shows that there are two regularities in foreign exchange markets in advanced countries with flexible regimes. First, real exchange rates are mean-reverting, as implied by the Purchasing Power Parity model. Second, the adjustment takes place via nominal exchange rates. These features...

This paper studies international trade and macroeconomic dynamics triggered by economic sanctions, and the associated welfare losses, in a calibrated, three-country model of the world economy. We assume that there are two production sectors in each country, and the sanctioned country has a...

Using firm-level data for 18 major global economies, we find that the exchange rate affects corpo-rate investment through a financial channel: exchange rate depreciation dampens corporate invest-ment through firm leverage and FX debt. These findings are consistent with the predictions of a...

Dominant currency pricing (DCP) weakens the demand-side effects of exchange rate changes on exports (Gopinath et al., 2020). However, adjustment in the export sector can still occur through other supply-side channels. With bilateral trade data at the HS2-product level, panel fixed-effects...

This paper assesses the financial channel of exchange rate fluctuations for emerging countries and the link to the conventional trade channel. We analyze whether the effective exchange rate affects GDP growth, the domestic credit and the global liquidity measure as the credit in foreign...

Member countries of the Organisation of Petroleum Exporting Countries (OPEC) are always in the news regarding the prices and supply of crude oil to the international market. One of the economic reasons for this is liquidity and the desire to accumulate international reserves by the respective...
