The present value model of the current account has been very popular, as it provides an optimal benchmark to which actual current account series have often been compared. We show why persistence in observed current account data makes the estimated optimal series very sensitive to small-sample...

This paper surveys the theoretical and empirical evidence on capital account convertibility and assesses its relevance for the reform states of Central and Eastern Europe. Its major findings are that domestic investment conditions matter and that domestic policies can reduce the risk of an...

This paper discusses the difference between Fisherian and Ricardian trade in terms of a simple two-period model of a small open economy. Fisherian or intertemporal trade occurs when goods are traded today against the promise to deliver goods in the future. The resulting net resource transfer is...

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...

During the last two decades, the degree of openness of national financial systems has increased substantially. At the same time, asymmetries in information and other financial market frictions have remain prevalent. We study both empirically and theoretically the implications of the opening up...

Results of empirical research have revealed a characteristic hump-shaped effect of monetary policy shocks on output: the effect builds to a peak after several months and then gradually dies out. We analyze, in the context of a "new open economy macroeconomics" model, factors that imply a...

This paper uses a ‘new open economy macroeconomics’ model to study the effect of a productivity shock on exchange rate dynamics. The special features of the model are that households’ preferences exhibit a "catching up with the Joneses" effect and that international financial markets are...

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 uses a dynamic general equilibrium two-country optimizing model to analyze the consequences of international capital mobility for the effects of monetary policy in open economies. The model shows that the difference between the short-run output effects of monetary policy shocks in a...

A number of empirical studies have reported the result that exchange rates show a delayed overshooting in response to monetary policy shocks. This result is puzzling. Economic theory suggests that the overshooting should occur immediately after the shock, not with a delay. This paper uses a...
