We analyze how the Bosman ruling affected the market for star players and talent development in the European football market. We develop a model with sports competition and endogenous ownership of star players in which we show how the stiffer bidding competition over star players after the...

Recent studies document a 30-year decline in various measures of entrepreneurship in the United States. In contrast, using detailed Swedish employer-employee data over the period 1990-2013, we find no decline in Swedish entrepreneurial activity. Aggregate net job creation is greatest among the...

We show that increasing the intensity of product market competition can reduce discrimination against female managers, even in an environment in which all employers have a preference for discrimination. The reason is that due to the glass ceiling effect, female managers will, on average, be more...

This paper examines employment and productivity dynamics in the Swedish business sector during the period 1996-2013. In order to analyze employment and productivity in a consistent way we apply a novel implementation of a method, which previously has been used extensively to analyze job...

When and how do entrepreneurs sell their inventions? To address this issue, we develop an endogenous entry-sale asymmetric information oligopoly model. We show that lowquality inventions are sold directly or used for own entry. Inventors who sell post-entry use entry to credibly reveal...

We construct a model where incumbents can either acquire basic innovations from entrepreneurs, or wait and acquire developed innovations from entrepreneurial firms supported by venture capitalists. We show that venture-backed entrepreneurial firms have an incentive to overinvest in development...

Private equity owned firms have more leverage, more intense compensation contracts, and higher productivity than comparable firms. We develop a theory of buyouts in oligopolistic markets that explains these facts. Private equity firms are more aggressive in inducing restructuring compared to...

We propose a model with asymmetric firms where new technologies displace workers. We show that both leading (low-cost) firms and laggard (high-cost) firms increase productivity when automating but that only laggard firms hire more automation-susceptible workers. The reason for this asymmetry is...
