This study replicates and challenges the finding of zero wage returns to compulsory schooling in Germany by Pischke and von Wachter (Review of Economics and Statistics, 90(3), 592-598), which is unusual in the literature yet widely cited and until now uncontradicted. I document that this finding...

Inequalities between workers of different skills have been growing in the era of globalization. Firms’ internationalization mode has an impact on job stability. Exporting firms are not only exposed to different foreign shocks, they also pay skill-intensive fixed costs to serve foreign markets....

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...

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...

We study the impact of techies—engineers and other technically trained workers—on firm-level productivity. We first report new facts on the role of techies in the firm by leveraging French administrative data and unique surveys. Techies are STEM-skill intensive and are associated with...

In the post-war period, the goods composition of trade in OECD countries has changed considerably. We analyze the evolution of comparative advantage using a detailed trade data set and a new analytical tool: the harmonic (weighted) mass index, which enables us to identify periods of structural...

This paper examines whether growth regressions should incorporate dualism and structural change. If there is a differential across sectors in the marginal product of labour, changes in the structure of employment can raise aggregate total factor productivity. The paper develops empirical growth...
