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...

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...

AT&T was known for both funding a world-class research lab and delaying deployment of useful innovations from the lab. To explain this behavior we consider a model with an incumbent facing a potential entrant. The incumbent can choose from two technologies for production: old and new. The...

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...

This paper proposes a theoretical framework for studying the invention of new products when demand is uncertain. In this framework, under general conditions, the threat of ex post entry by a competitor can deter invention ex ante. Asymmetric market power in the ex post market exacerbates the...

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?...

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...
