We discuss the incentive of an exclusive holder of a technology to share it with competitors in a market with network externalities. We assume that high expected sales increase the willingness to pay for the good. This is named the "network effect". At a stable fulfilled expectations...

Entry into a network industry is modeled, focusing on consumers' expectations formation. Equilibrium expectations are endogenous and they depend on prices, acting as a coordination device among consumers. The model is able to account for aggressive pricing policies by the incumbent and by the...

The United States central government enactment of the 1866 Post Roads Act preempted state and municipal telegraph franchise entry barriers. Like present-day telecommunication companies, local franchise regulations were an entry barrier to United States telegraph companies. These pre-1866 state...

The reluctance of antitrust to condemn parallel exclusion permits oligopolies to be entrenched. This is because parallel exclusion — multiple-firm conduct that inhibits market entrants — cannot satisfy the current strictures of monopolization, which is understood to prohibit single-firm...

This paper analyzes tying and bundling as an entry deterrence tool. It shows that a multi-product firm can defend its monopoly position in one market via tying even when it does not have market power in another market. This is shown on a model with two complementary goods, each of which is...

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...

Consider an incumbent monopolist faced with potential competitors who can enter the market by developing a substitute, but inferior, technology. What is the incumbent's optimal licensing policy? When, to whom and under what conditions should the incumbent firm license its superior technology?...

This paper studies how the existence of a potential entrant influences an incumbent's choice of quality in a model of vertical product differentiation and entry. Both firms face fixed set-up costs and quality-dependent costs of production and compete on quality and price. With identical...

This paper reports the results of a series of two-stage, two-person non-cooperative games where one player can strategically preempt the other. In one of our designs, the subgame perfect equilibrium entails complete preemption; in the other, it entails partial preemption. Logit analysis...
