A central debate in economics concerns the relationship between competition and innovation, with some stressing that competition discourages innovation by reducing post-innovation rents and others emphasizing that more contestable markets spur currently dominant and other firms to invest more in...

We propose a method for bounding the demand elasticity in growing, homogeneous-product markets that requires only minimal data--market price and quantity over a time span as short as two periods. Reminiscent of revealed-preference arguments using choices over time to bound the shape of...

Open borders imply systems competition. This paper studies the implications of systems competition for the national competition rules. It is shown that an equilibrium where all countries retain their antitrust laws does not exist, since abolishing this law makes it possible for a single country...

In this paper we review issues relating to antitrust and competition in health care markets. The paper begins with a brief review of antitrust legislation. We then discuss whether and how health care is different from other industries in ways that might affect the optimality of competition. The...

This paper presents an empirical analysis of the relationship between patenting, innovation, and federal antitrust enforcement towards firms in the manufacturing sector. I examine whether the likelihood of antitrust litigation is influenced by patent histories and R&D expenditures, after...

Antitrust authorities search public documents to discover anticompetitive mergers. Thus, investor disclosures may alert them to deals that would otherwise escape scrutiny, creating disincentives for managers to divulge transactions. We study this behavior in publicly traded US companies. First,...

This paper deals with the effect of trade restrictions on competition in oligopolistic markets. Quantitative restrictions, such as VER's (Voluntary Export Restrictions) are shown to affect the extent to which foreign firms can compete in the domestic market, and hence to raise the equilibrium...

In this paper we examine exclusion accomplished by a coalition of firms--frequently, a coalition of suppliers and customers--that share the benefits of exclusion. As a particular historical example, we study the Canadian sugar industry of the 1880s, which was controlled by a complex coalition of...

The goal of antitrust policy is to protect and promote a vigorous competitive process. Effective rivalry spurs firms to introduce new and innovative products, as they seek to capture profitable sales from their competitors and to protect their existing sales from future challengers. In this...
