In this note, we show that labour market integration can be a double-edged sword. In the presence of local human capital externalities, integration and the ensuing agglomeration of skilled labour can cause a decline in human capital and the total wage sum (net of education costs). In particular,...

Elite skills have become crucial in today’s superstar economy. We develop a multi-period skillformation model where we show that individuals with temporary disadvantages must exert greater effort to gain access to elite education. This “underdog-incentive effect” implies that “educated...

We develop novel measures of early-career skills that are more detailed, comprehensive, and labor-market-relevant than existing skill proxies. We exploit that skill requirements of apprenticeships in Germany are codified in state-approved, nationally standardized apprenticeship plans. These...

This paper investigates how the size of co-ethnic networks at the time of arrival affect the economic success of immigrants in Germany. Applying panel analysis with a large set of fixed effects and controls, we isolate the association between initial network size and long-run immigrant outcomes....

We analyze the welfare effects of trade and migration, focusing on two-sided horizontal heterogeneity among workers and firms. We prove the existence of a unique symmetric equilibrium in a two stage game of firm entry (including choice of skill-types) and pricing, involving monopsony power on...

This paper studies the relationship between changes in occupational employment, occupational wages, and rising overall wage inequality. Using long-running administrative panel data with detailed occupation codes, we first document that in all occupations, entrants and leavers earn lower wages...

The canonical supply-demand model of the wage returns to skill has been extremely influential; however, it has faced several important challenges. Several studies show that the standard approach sometimes produces theoretically wrong-signed elasticities of substitution, yields counterintuitive...

This paper studies how linear tax and education policy should optimally respond to skill-biased technical change (SBTC). SBTC affects optimal taxes and subsidies by changing i) direct distributional benefits, ii) indirect redistributional effects due to wage-(de)compression, and iii) education...

We analyze self-selection and sorting of emigrants from Finland, using full-population administrative data from Statistics Finland. We analyze emigration events lasting at least five years and decompose migrant self-selection into education, occupation, and unobserved abilities. Our analysis...

This article analyzes the effect of public policy intervention in the production of health capital on fertility, private investment in children's health and education and human capital accumulation. I have used a growth model with endogenous fertility, in which the usual parental trade-off...
