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...

We find an inverted relation between a player's birthday and the likelihood of receiving the Ballon d'Or (awarded to the best football player in the world). We develop a multi-period skill formation model with selection into elite education. We show that those born late (underdogs) need to work...

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...

Private equity firms (PE firms) have become common owners of established firms in concentrated markets. We show that the threat of a PE acquisition can trigger incumbent mergers in an otherwise mergerstable industry. This can help antitrust authorities maximize consumer surplus because...

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...

What explains the world-wide trend of pro-entrepreneurial policies in the last few decades? We study entrepreneurial policy in a lobbying model taking into account the conflict of interest between entrepreneurs and incumbents. It is shown that international market integration leads to more...

We develop a theory of commercialization mode (entry or sale) of entrepreneurial inventions into oligopoly, and show that an invention of higher quality is more likely to be sold (or licensed) to an incumbent due to strategic product market effects on the sales price. Moreover, preemptive...
