This paper presents a modified and improved methodology for the decomposition of wage differentials between two groups of workers into an endowment component and a discrimination component. The standard decomposition technique does not take into account different probabilities of entering the...

This paper examines hierarchies’ role in the organization of human-capital-intensive production. We develop an equilibrium model of hierarchical organization, then provide empirical evidence using confidential data on thousands of law offices from the 1992 Census of Services. We show how the...

This paper analyzes the early research performance of PhD graduates in labor economics, addressing the following questions: Are there major productivity differences between graduates from American and European institutions? If so, how relevant is the quality of the training received (i.e....

This paper studies the effect of top tax rates on inventors' mobility since 1977. We put special emphasis on "superstar" inventors, those with the most and most valuable patents. We use panel data on inventors from the United States and European Patent Offices to track inventors' locations over...

There is a considerable empirical literature which compares wage levels of workers who have studied at secondary vocational schools with wages of workers who took academic schooling. In general, vocational education does not lead to higher wages. In some countries where labour markets are...

This Paper analyses transitions into and out of three different labour market states: social assistance, unemployment and employment. We estimate a dynamic multinomial logit model, controlling for endogenous initial conditions and unobserved heterogeneity, using a large representative Swedish...

This paper analyses differences in welfare utilization between immigrants and natives in Sweden using a large panel data set, LINDA, for the years 1990 to 1996. Both welfare expenditures and immigration increased substantially in Sweden in the 1990's. We find that immigrants use welfare to a...

This Paper provides a snapshot of the stock of immigrants in Germany using the 1995 wave of the Mikrozensus, with a particular emphasis on distinguishing first- and second-generation migrants. On the basis of this portrait, we draw attention to the empirically most relevant groups of immigrants...

Workers can have good or bad work habits. These traits are transmitted from one generation to the next through a learning and imitation process which depends on parents' investment on the trait and the social environment where children live. We show that, if a high enough proportion of employers...

We study the impact of employment quota on firms' demand for disabled workers. The Austrian Disabled Persons Employment Act (DPEA) requires firms to provide at least one job to a disabled worker per 25 non-disabled workers, a rule which is strictly enforced by non-compliance taxation. We find...
