We argue that the arrival of immigrants with low reservation wages can strengthen the monopsony power of firms. Firms can exploit "cheap" migrant labor by offering lower wages, though at the cost of forgoing potential native hires who demand higher wages. This monopsonistic trade-off can lead to...

Principal-agent models take outside options, determining participation and incentive constraints, as given. We construct a general equilibrium model where workers' reservation wages and the maximum punishment acceptable before workers quit are instead determined endogenously. We simultaneously...

Labor market tightness tremendously increased in Germany between 2012 and 2022. We analyze the effect of tightness on wages by combining social security data with unusually rich information on vacancies and job seekers. Instrumental variable regressions reveal positive elasticities between 0.004...

The study replicates the first European field experiment on gay men's labor market prospects in Greece. Utilizing the same protocol as the original study in 2006-2007, two follow-up field experiments took place in 2013-2014 and 2018-2019. The study estimated that gay men experienced occupational...

This note tests whether the extraordinary rise in Spanish unemployment in the 1980s can be traced back to rigidities in the wage structure in the face of relative net demand shocks against the unskilled (this claim is also known as the "Krugman hypothesis"). I can establish that youth...

Immigrants are more likely to have conationals as colleagues, however the consequences of such workplace segregation is an open question. I study the effect of the conational share in an immigrant's first job on subsequent labour market outcomes using register data from Germany. I instrument for...

The Netherlands have experienced an employment miracle since the 1980s. This note investigates what happened to the wage, unemployment, and non-employment structures between 1988 and 1998, when both unemployment and non-employment rates decreased markedly. Surprisingly, I find no significant...

Do employers in “non-STEM” occupations (e.g. Graphic Designers, Economists) seek to hire STEM (Science, Technology, Engineering, and Mathematics) graduates with a higher probability than non-STEM ones for knowledge and skills that they have acquired through their STEM education (e.g....

We study the market for CEOs of large publicly-traded US firms, analyze new CEOs’ prior connections to the hiring firm, and explore how hiring choices are determined. Firms are hiring from a surprisingly small pool of candidates. More than 80% of new CEOs are insiders, defined as current or...
