Firm Heterogeneity in Skill Returns

Abstract. This paper presents new evidence on worker–firm complementarities. We combine matched employer-employee data with direct measures of workers’ cognitive and noncognitive skills, and propose an empirical approach that separately identifies the firm-level return for each attribute. We find that similar skills command different returns across employers and that workers’ sorting into firms depends on returns to both attributes. We derive theoretical restrictions that characterize many-to-one matching in employer-employee data, linking within-firm skill dispersion to between-firm differences in average skills. Estimates support these restrictions. Firm heterogeneity in skill returns raises both the average level and dispersion of earnings.

Giovanni Gallipoli is a professor at UBC in Vancouver. Giovanni's research focuses on the origins and consequences of economic inequality with a focus on how heterogeneity shapes individual behaviors and aggregate economic outcomes. Giovanni has worked on a variety of topics, including the equilibrium effects of policies that promote skill formation; the link between skill heterogeneity and a country's comparative advantage; the influence of families on long-term outcomes such as labor supply and consumption; intergenerational mobility and the linkages between parental heterogeneity and inequality; and how firm-level differences contribute to variation in workers’ skill returns. Giovanni is a recipient of the Killam Research Award, the FEEM Award, and the Young Economist Award of the European Economic Association. He is a CEPR research fellow as well as a former Fulbright Scholar and Weatherhall fellow. He serves as a member of the external board of overseers of the Panel Study of Income Dynamics (PSID) and as an associate editor of the Journal of Political Economy. Giovanni is an alumnus of the Sant'Anna School of Advanced Studies and the University of Pisa in Italy. He received his Ph.D. in Economics from University College London in the UK.
