Racial Discrimination in the Labor Market of English Football Managers
(with Thomas Peeters and Stefan Szymanski)
We study racial disparities in advancement to top management using the careers of 4,770 former frontline workers from a prominent industry in England. Black workers are substantially less likely than non-Black workers to reach top managerial positions (11 versus 20 percent). We identify three sources of this gap: lower entry into management, lower promotion rates within management, and shorter tenure in senior managerial roles. Counterfactual simulations show that barriers to entering management explain most of the racial gap early in workers’ careers, while differences in promotion rates become the dominant driver later on.

Skilled leaders may influence both individuals’ progression into management and their subsequent success as managers. Using 60 years of European professional football data, we track transitions from player to manager. High-performing players are more likely to become managers, but are not better managers. By contrast, those exposed to high-ability managers are more likely to enter management and are more effective once appointed. In particular, exposure to high-ability managers late in a playing career matters most for later managerial performance. Moreover, the effect is domain-specific, with scoring and defending exposure associated with later managerial ability in the same domain.

One’s Pain is Another’s Gain – Early Career Exposure and Later Labour Market Outcomes
– Journal of Law, Economics, and Organization, 2026
Abstract:
This paper investigates whether early career exposure of unexperienced employees to employers affects their later career outcomes. The extent to which entry-level workers get to demonstrate their abilities is an important determinant of how precisely the employer can estimate their talent. A common difficulty in the literature is finding relevant measures of how often the employer observes an employee. To this end, I use high frequency worker-level data from the National Hockey League, where in-game playing time serves as the measure of exposure. I implement a novel instrumental variable strategy, exploiting co-worker injuries as a source of random variation in junior worker playing time. Co-worker injuries create vacant slots in team rosters, which are usually filled by junior workers, increasing their exposure. Consequently, there is a positive correlation between the number of co-worker injuries that occur and the number of playing opportunities that a junior worker gets during their entry-level career. Using co-worker injuries as an instrument, the results indicate that total entry-level career playing time significantly increases a junior worker’s likelihood of being rehired as well as their post entry-level salary.

Work Style Diversity and Diffusion Within and Across Organizations: Evidence from Soviet-style Hockey (wp version)
(with Francesco Amodio and Jeremy Schneider)
– Management Science, 2024
Abstract:
Does the arrival of culturally diverse workers affect the work style of incumbent workers? We examine how the large influx of Russian hockey players in the National Hockey League (NHL) after 1989 affected North American born players. The Soviet style of hockey was largely based on skilled skating, constant movement, circling and passing. In contrast, the North American play was more individualistic and linear, with higher emphasis on physical strength and aggressive behavior. Using 50 years of data at the player-game level, we show that (i) the number of penalty minutes per game increases steadily from 1970 to 1989, but decreases thereafter; (ii) although Russian players get systematically fewer penalty minutes in and after 1989, the trend reversal is driven by North American born players; (iii) the number of penalty minutes per game of North American born players decreases systematically with the number of Russian players on their team and on the opposing team.Evidence shows that the hockey style brought about by Russian players was adopted and diffused within and across North American teams and players.

The Impact of Absent Co-workers on Productivity in Teams
(with Jan van Ours & Thomas Peeters)
– Labour Economics, 2023
Abstract:
We study how workers in production teams are affected by the temporary absence and replacement of a coworker. When a substitute coworker is absent, the remaining coworkers produce less output per working time. They compensate for this by increasing their working time at the expense of the (less able) replacement worker, such that the output loss per remaining worker is not significant. When a complementary coworker is absent, we see a similar loss in output per minute worked, but this directly leads to a loss of output produced, because remaining workers do not take over the absent worker’s tasks.

The transfer system in European football: a pro-competitive no-poaching agreement?
(with Thomas Peeters and Francesco Principe)
– International Journal of Industrial Organization, 2021
Abstract:
We assess the proclaimed pro-competitive effects of the “transfer system”, the no-poaching agreement governing the European football (soccer) labor market. A major argument to legitimize this system is that transfer fees, which hiring clubs pay to release players from their current clubs, redistribute revenues from large market to small market clubs. This would strengthen small clubs’ financial clout and their ability to compete in sporting terms. Player transfer fees represent over 10 billion Euros in asset value in the financial statements of the 202 clubs we analyze. Still, small market clubs rarely obtain substantial revenues from the transfer market. The main beneficiaries are clubs around the middle of the market size distribution. A select group of large market clubs makes significant transfer losses, but this does not undo their initial financial advantage. Overall, the transfer system therefore leads to a very minor reduction in revenue inequality.
