This paper presents a theoretical model about the optimal choice for a firm between offshoring and hiring immigrant workers under asymmetric information about their ability and effort in production (symmetric information is assumed about home born workers). When a domestic firm hires an...

We consider Roy's economies with perfectly competitive labor markets and asymmetric information. Firms choose their investments in physical capital before observing the characteristics of the labor markets they will face. We provide conditions under which equilibrium allocations are constrained...

The social and the private returns to education differ when education can increase productivity, and also be used to signal productivity. We show how instrumental variables can be used to separately identify and estimate the social and private returns to education within the employer learning...

Mobile workers involve flows of labor and human capital and contribute to a more efficient allocation of resources. However, migration also changes relative wages, alters the distribution of skills and affects equality in the receiving society. The paper suggests that skilled immigration...

This paper presents a simple Chamberlinian agglomeration model which, like the canonical core-periphery (CP) model, contains two agglomerative forces. However, in contrast to that model, the present model is analytically solvable. Moreover, the present model exhibits a 'supercritical pitchfork...

This paper presents a simple, analytically solvable Chamberlinian agglomeration model. As in the canonical core-periphery (CP) model, two agglomerative forces are at work. However, the present model exhibits a "pitchfork bifurcation" rather than the "tomahawk bifurcation" of the CP model.

It is commonly believed that accumulation of human capital (HC) and availability of physical and financial capitals are among the major determinants of economic growth. In a globalised world, where factors of production are increasingly mobile, the process of domestic accumulation of HC might be...
