Granular Search, Market Structure, and Wages
écrit avec Jan Sebastian Nimczik and Isaac Sorkin
We develop a model where labor market structure affects the division of surplus between
firms and workers. In a model of random search and large employers, workers might apply
to another job controlled by the same employer in the future. This possibility endows firms
with size-based market power. The reason is that outside options are truly outside the firm:
firms do not compete with their own vacancies. Hence, a worker’s outside option is worse when
bargaining with a larger firm, and wages depend on market structure. We calibrate the model
to Austrian data and find that such size-based market power depresses wages.

*A "soft" war of attrition
I analyse a “soft” war of attrition in a procurement auctions framework inspired by renewable energy auctions in India. Before the auction, the auctioneer declares the quantity of a product it wants, and each bidder declares the amount they can provide. The bidders compete on prices in an open descending price auction. Winners provide the quantity they declared, a partial loser provides the residual demand, and full losers provide zero. I characterise perfect Bayesian equilibrium in these games under incomplete information and common prior in diverse cases. The payoff structure leads to bunching at the reserve price in the PBE by the bidder with the highest quantity. I conjecture the existence of an equilibrium, and prove that if it exists, it is unique. The presence of bunching and asymmetric payoff can lead to inefficient selection in such auctions. While developed as an auction, the framework can be easily extended to any game of sequential exit.

Encouraging and directing job search: direct and spillover effects in a large scale experiment.
écrit avec Sofia Dromundo, Marc Gurgand, Yagan Hazard and Thomas Zuber
We analyze the employment effects of directing job seekers’ applications towards estab- lishments likely to recruit, building upon an existing Internet platform developed by the French public employment service. Our two-sided randomization design, with about 1.2 mil- lion job seekers and 100,000 establishments, allows us to precisely measure the effects of the recommender system at hand. Our randomized encouragement to use the system induces a 2% increase in job finding rates among women. This effect is due to an activation effect (in- creased search effort, stronger for women than men), but also to a targeting effect by which treated men and women were more likely to be hired by the firms that were specifically recommended to them.
In a second step, we analyze whether these partial equilibrium effects translate into pos- itive effects on aggregate employment. Drawing on the recent literature on the econometrics of interference effects, we estimate that by redirecting the search effort of some job seekers outside their initial job market, we reduced congestion in slack markets. Estimates suggest that this effect is only partly offset by the increased competition in initially tight markets, so that the intervention increases aggregate job finding rates.

*Male Fertility: Facts, Distribution and Drivers of Inequality co-authored with Bernt Bratsberg and Andreas Kotsadam
We document new facts on the distribution of male fertility and its relationship with men's labor market outcomes. Using Norwegian registry data, we uncover a "retreat from fertility": the gap in male childlessness between low and high earners has widened by almost 20 percentage points over the last thirty years, resulting in a remarkable compression of the fertility distribution. Using firm bankruptcies, we show that men experiencing negative labor market shocks are persistently less likely to become fathers and be partnered for at least 15 years after the event. We conclude by documenting that men's fertility penalty to job loss has increased markedly over the last three decades. A challenging labor market fails to shield low income workers with serious implications for family formation.
