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...

This study examines the causal influence of digital technologies, specifically operational (ODT) and information digital technologies (IDT), on firms' employment structure using Italian firm-level data. It employs a unique empirical approach, constructing instrumental variables based on...

This paper studies the consequences of the buildup of a new economic sector—the Norwegian petroleum industry—on investment in human capital. We assess both short-term and long-term effects for a broad set of educational margins, by comparing individuals in regions exposed to the new sector...

I use data from the World Input-Output Database and show that trade in information technologies (IT) has a significant contribution to the growth in foreign intermediate goods in the 2001-2014 period. China has strongly contributed to the rise in trade in IT and has become one of the major...

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...

In recent decades, many industrialized economies have witnessed a pattern of job polarization. While shifts in labor demand, namely routinization or offshoring, constitute conventional explanations for job polarization, there is little research on whether shifts in labor supply along the labor...

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...

We investigate minimum wage spillovers by exploiting the first-time introduction of a minimum wage within a quasi-experiment in a context with an extraordinary large bite: the German roofing industry. We find positive wage spillovers for medium-skilled workers with wages just above the minimum...

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...
