The paper applies Ricardo's principle of comparative advantage to analyze the substitutability between types of labor. The problem of having to classify labor in a small number of types in e.g. standard CES models are avoided by applying a continuum of worker and job types, where better skilled...

In a corporatist country, of which the Netherlands is an example, wages should not be distinguished by union membership status, but by the bargaining regime. Four bargaining regimes can be distinguished: (i) company level bargaining, (ii) industry level bargaining, (iii) mandatory extension of...

In this paper we derive a structural measure for labor market density based on the Ellison and Glasear (1997) Index for industry concentration. This labor market density measure serves as a proxy for the number of workers that can reach a certain work area within a reasonal amount of traveling...

This paper describes a search model with a continuum of worker and job types, free entry and transferable utility. We apply a second-order Taylor expansion to characterize the equilibrium, derive the cost of search and show that it is decreasing in the substitutability of worker types. This cost...

Though a lot of work has been done on the distribution of job tenures, we are still uncertain about its main determinants.In this paper, we stress random shocks to match productivity after the start of an employment relation.The specificity of investment makes hiring and separation decisions...

The stock market collapse led to political tensions between generations due to the fuzzy definition of the property rights over the pension funds’ wealth. The problem is best resolved by the introduction of generational accounts. Modern consumption and portfolio theory shows that the younger...

Estimates of the effect of education on GDP (the social return) have been hard to reconcile with micro evidence on the private return to schooling. We present a simple explanation combining two ideas: imperfect substitution and endogenous skill-biased technological progress and use cross-country...

I apply Ricardo’s principle of comparative advantage to a theory of factor substitutability in a model with a continuum of worker and job types. Highly skilled workers have a comparative advantage in complex jobs. The model satisfies the distance-dependent elasticity of substitution (DIDES)...

We develop a model of an economy with several regions, which differ in scale. Within each region, workers have to search for a job-type that matches their skill. They face a trade-off between match quality and the cost of extended search. This trade-off differs between regions, because search is...
