I develop an intra-firm theory of group design and teamwork in the presence of peer effects. The purpose is to understand the interlinkages between intra-firm group formation and the extent of wage dispersion within the firm. Given a set of heterogeneous workers, the manager faces the challenge...

The main function of hierarchies is to coordinate activities within an organisation, but a hierarchical structure also provides work incentives, by offering the prospect of hierarchical mobility. An alternative way for organisations to motivate workers is through job design. In organisations...

We use data on twins matched to register-based information on earnings to examine the long-standing puzzle of non-existent compensating wage differentials. The use of twin data allows us to remove otherwise unobserved productivity differences that were the prominent reason for estimation bias in...

We develop a search model of informal labor markets with worker and firm heterogeneity, intra-firm bargaining with imperfect substitutability across types of workers, and a comprehensive set of labor regulations, including minimum wage. Stylized facts associated with the informal sector, such as...

In this paper we develop a model capturing key features of the Roy model, a search model, compensating differentials, and human capital accumulation on-the-job. We establish which features of the model can be non-parametrically identified and which cannot. We estimate the model and use it to...

The large inflow of less-educated immigrants that the United States has received in recent decades can worsen or improve U.S. natives' labor market opportunities. Although there is a general consensus that low-skilled immigrants tend to hold "worse" jobs than U.S. natives, the impact of...

This paper presents on three new styled facts: first, schools of public affairs hire many economists; second, those economists are disproportionately female; and third, salaries in schools of public affairs are, on average, lower than salaries in mainline departments of economics. We seek to...

Using linked employer-employee data from Brazil, we document a large gender pay gap due to women working at lower-paying employers with better nonpay attributes. To interpret these facts, we develop an equilibrium search model with endogenous firm pay, amenities, and hiring. We provide a...
