The Balassa-Samuelson model, which explains real exchange rate movements in terms of sectoral productivities, rests on two components. First, the model implies that the relative price of non-traded goods in each country should reflect the relative productivity of labour in the traded and...

This paper reviews the problems that must be resolved at the Intergovernmental Conference in 1996 to clear the way for European Monetary Union: locking in Germany's commitment to the project, and reconciling EMU with variable geometry. It reviews what we know about the costs and benefits of EMU...

We study how the city system is affected by the possibility for the members of the same cultural diaspora to interact across different cities. In so doing, we propose a simple two-city model with two mobile cultural groups. A localized externality fosters the productivity of individuals when...

We ask whether Poland is at risk of the boom-bust problem that has afflicted economies around the time of euro adoption. Our answer, inevitably, is mixed. On the one hand the fact that Poland is an outlier, credit-growth wise, accentuates the danger of a boom if one believes in mean reversion....

In this paper we analyse the recent efforts of the international financial institutions to limit the moral hazard created by their assistance to crisis countries.

Learning by exporting refers to the mechanism whereby firms improve their performance (productivity) after entering export markets. Although this mechanism is often mentioned in policy documents, a significant share of econometric studies has not found evidence for this hypothesis. This paper...
