The additionality principle says that the funds of the European Union should not replace, but be an addition to national regional policy funds. The benchmark for the co-funding is that the EU bears 50% of total costs associated with regional projects eligible for EU support. In some regions,...

This paper studies the influence of interregional inequality within countries on internal con-flicts. Regional inequalities are measured by the population-weighted coefficient of variation of regional GDP per capita. As the main innovation, I use a panel data set of country-level re- gional...

We study the effect of international trade and freeness of trade (openness) on interregional inequality within countries. We estimate a model derived from a structural economic-geography approach in which interregional inequality depends on weighted trade shares and trade costs. In addition to...

Applying the methodology developed by Duranton and Overman (2005, 2008), we analyze localization and dispersion of firms in China. Using a unique and detailed dataset on manufacturing firms in China, we are able to follow the changes in location patterns of firms between 2002 and 2008. Our...

Regional productivity differences provide scope for productivity-enhancing labor mobility. Redistribution reduces relocation incentives through higher taxes or lower transfers. Combining an intensive labor supply margin with an extensive, productivity-enhancing migration margin, we determine how...

Foreign direct investments (FDI) are an important determinant of economic growth. Coun-tries try to attract mobile capital in order to foster economic development, albeit FDI might increase regional inequality since the many different regions of a country usually do not receive FDI in equal...

Why do cities differ so much in productivity? We document that most of the measured dispersion in productivity across US cities is spurious and reflects granularity bias: idiosyncratic heterogeneity in plant-level productivity and size, combined with finite plant counts. As a result, economies...

We use a quantitative model to study the implications of European integration for welfare and migration flows across 1,318 regions. The model suggests that an increase of trade barriers to the level of 1957 reduces welfare by about 1-2 percent on average, depending on the presumed trade...

This paper investigates the main determinants of the regional representation of foreign employees in Germany. Since migration determinants are not necessarily the same for workers of different nationalities, we explain spatial patterns not only for total foreign employment but also for the 35...

We study the effect of spatial inequality on economic activity. Given that the relationship is highly simultaneous in nature, we use exogenous variation in geographic features to construct an instrument for spatial inequality, which is independent from any man-made factors. Inequality measures...
