We consider consumer entry in the canonical monopolistic nonlinear pricing model ( Mussa and Rosen 1978) wherein consumers learn their preference “types” after incurring privately known entry costs. We show that by taking into account consumer entry, the nature of optimal nonlinear pricing...

We study different determinants of real-life R&D decisions within a net present value framework. Besides entry threat, Bertrand competition and multi-stage R&D with an abandonment option, our model includes demand uncertainty, modelled as a lottery. A lottery becomes more divergent when the...

This paper attempts to assess the variety and relevance of barriers to entry perceived by Portuguese firms. Based on a questionnaire, Portuguese firms' perceptions were surveyed using a sample of 168 firms. The results suggest that sunk costs, capital requirements, capital costs, and cost...

This paper extends the traditional analysis of the output effect under monopoly (third- degree) price discrimination to a multimarket oligopoly. The author shows that under oligopoly price discrimination, differences in competitive pressure, measured by the number of firms, across markets are...

This paper studies the price-setting problem of a monopoly that in each time period has the option of failing to deliver its good after receiving payment. The monopoly may be induced to deliver the good if consumers expect that the monopoly will not deliver in the future if it does not deliver...

We analyze a vertically differentiated market for an imperfectly durable good served by a monopolist in an infinite-horizon, discrete-time game. Our goal is to identify the Markov perfect stationary equilibria where the seller can maintain his monopoly power. We establish that the set of...
