We extend the Altonji and Card (1991) framework for analysing the impact of immigrants on natives' wages from two to three labour types and estimate reduced form wage equations for The Netherlands, United Kingdom and Norway. We find very small effects on natives' wages and no dominant robust...

We extract estimation results on the Mincer earnings function from four earlier studies and add new results from a recent dataset. We analyse differences related to differences in earnings concepts, in sampling frame and differences among studies that cannot be explained. Jointly, the studies...

How valuable are cognitive and social abilities for entrepreneurs’ incomes as compared to employees? We answer three questions: (1) To what extent does a composite measure of ability affect an entrepreneur's earnings relative to employees? (2) Do different cognitive abilities (e.g. math...

Comparing cohorts born between 1951 and 1994, we document and interpret changes in the wage differential among graduates from secondary education with a vocational and a general curriculum. The wage gap initially increased and then decreased. We find that these changes cannot be attributed to...

We apply a recently proposed method to disentangle unobserved heterogeneity from risk in returns to education. We replicate the original study on US men and extend to US women, UK men and German men. Most original results are not robust. A college education cannot universally be considered an...

We combine profit sharing for high-skilled workers and outsourcing of low-skilled tasks in partly imperfect dual domestic labour markets, when the wage rate for low-skilled worker is set by a labor union, to analyze how the implementation of profit sharing influence flexible outsourcing and...

We analyse the information in the Dictionary of Occupational Titles to characterize the structure of labour demand. Two dimensions, an intellectual factor and a dexterity factor capture most variation in job requirements. Job complexity in relation to Things correlates highly with the dexterity...

This paper deals with optimal income taxation under labor outsourcing and FDI. We show how the optimal income tax response to the joint effect of outsourcing and FDI depends on whether FDI is complementary with, or substitutable for, domestic labor. -- outsourcing ; foreign direct investment ;...
