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...

This paper proposes a theory of gazelle growth in which gazelles can either grow organically or by acquisitions. In the model, there are three types of firms: incumbent, target, and gazelle. We show that the lower cost of organic growth can increase the incentives for acquisition growth. 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...

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 provide empirical evidence that uncertainty (rather than risk) and optimism are distinctive characteristics of high-impact entrepreneurial firms (recently listed firms) relative to old, incumbent firms. Based on this evidence, we construct an entrepreneurial entry predation model with...

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...

Entrepreneurs face higher commercialization costs than incumbents. We show that this implies that entrepreneurs will choose more risky projects than incumbents, aiming to reduce their high expected marginal commercialization cost. However, entrepreneurs may select too safe projects from a social...

Research on entrepreneurship has flourished in recent years and is evolving rapidly. This paper explores the history of entrepreneurship research, how the research domain has evolved, and its current status as an academic field. The need to concretize these issues stems partly from a general...
