We consider market dynamics in a reduced form model. In the simplest version, there are two investors and several small noninvesting firms. In each period, one investor can acquire a small firm, the other investor decides about market entry. After that all firms play an oligopoly game. We derive...

We study the anticompetitive effects of predatory pricing and the efficacy of three policy responses. In a series of experiments where an incumbent and a potential entrant interact, we compare prices, market structures and welfare. Under a laissez-faire regime, the threat of post-entry price...

We analyze entry of a firm with a new and differentiated product into a market with two properties: An existing incumbent has a captive consumer base, and all consumers have heterogeneous tastes. The interaction of the share of captive consumers with the degree of taste heterogeneity leads to...

To examine the impact of globalization on managerial compensation, we consider a matching model where firms compete both in the product market and in the managerial market. We show that globalization, that is, the simultaneous integration of product markets and managerial pools, leads to an...

This paper provides a novel theory of research joint ventures for financially constrained firms. When firms choose R&D portfolios, an RJV can help to coordinate research efforts, reducing investments in duplicate projects. This can free up resources, increase the variety of pursued projects and...

This paper analyzes decisions of multi-product firms regarding product selection, innovation and advertising as choices of consumer valuation distributions. We show that a profit-maximizing monopolist chooses these distributions so as to maximize the dispersion of the valuation differences...
