Spatial wage disparities can result from spatial differences in the skill composition of the workforce, in non-human endowments, and in local interactions. To distinguish between these explanations, we estimate a model of wage determination across local labour markets using a very large panel of...

In 1997 GDP per capita in East Germany was 57% of that of West Germany, wage rates were 75% of western levels, and the unemployment rate was at least double the western rate of 7.8%. One would expect that if capital flows and trade in goods failed to bring convergence, labour flows would...

This paper presents empirical tests of the hypothesis that firms cluster geographically due to Marshallian localization economies. The hypothesis implies that changes in employment in localized industries should be more closely related within the regions than across regions. We develop an...

The Paper studies determinants of internal migration in Russia. Using panel data on gross region-to-region migration flows in 1992-99, we estimate the effect of economic, political and social factors. Although overall migration is rather low, it turns out that its intensity does depend on...

Inter-regional migration is influenced by relative employment and earnings opportunities. But strongly offsetting forces operate from relative house prices. Commuting, at least to contiguous regions, is often an alternative to migration. Relative employment and earnings opportunities should...

This paper models how migration both influences and responds to differences in disease prevalence between cities, regions and countries, and show how the possibility of migration away from high-prevalence areas affects long-run steady state disease prevalence. We develop a dynamic framework...

Does productivity increase with density? We revisit the issue using French wage and TFP data. To deal with the ‘endogenous quantity of labour’ bias (i.e., urban agglomeration is consequence of high local productivity rather than a cause), we take an instrumental variable approach and...

Typically, a small and open economy trades goods at given world prices. Here, we present a model of a very open small economy, where capital and labour are internationally mobile, too. When investing into infrastructure, the economy’s government attracts not only mobile capital but mobile...

The striking geographical concentration of economic activities suggests that there are substantial benefits to agglomeration. The nature of those benefits remains unclear, however. In this Paper we take advantage of a new dataset to quantify the role of one of the main contenders: the matching...

In this paper we document a strong positive correlation of immigration flows with changes in average wages and average house rents for native residents across U.S. states. Instrumental variables estimates reveal that the correlations are compatible with a causal interpretation from immigration...
