The paper discusses alternative options for a future monetary order in the area of the Soviet Union. Its main focus is on two questions: Under what conditions would a common rouble currency area be compatible with fiscal discipline and effective financial control over the large numbers of...

We develop a theory of multiproduct firms to analyze the effects of globalization on the distributions of firm size, scope, and productivity. In the model, firms are heterogeneous in how well they cope with expanding their product range. The model generates a negative relationship between firm...

This Paper studies the evolution of sectoral labour concentration in relation to the level of per capita income. We show that various measures of sectoral concentration follow a U-shaped pattern across a wide variety of data sources: countries first diversify, in the sense that labour is spread...

This paper deals with the investment effects of regional integration agreements and discusses how such arrangements may affect inward and outward foreign direct investment (FDI) flows in the integrating region. After setting up a conceptual framework for the analysis, we provide three studies...
