Over the past two decades, private equity has contributed to a shrinking of the U.S. stock market. We develop a political economy model of private equity activity to study the wider economic consequences of this trend. We show that private and social incentives to delist firms from the stock...

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...

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...

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...

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...

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...

Many governments promote small businesses for the dual reasons of fostering 'breakthrough' innovations and employment growth. In this paper we study the effects of tax and subsidy policies on entrepreneurs' choice of riskiness of an innovation project and on their mode of commercializing the...

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...
