We analyze differentiated retail industries where shops engage in two-stage competition with respect to opening hours and prices. We explore the effects of consumers' shopping time flexibility by comparing bi-directional consumers with forward- or backward-oriented consumers, who can either...

Random choices of prices and product characteristics can be used by a contestable monopolist to deter entry and fully extract the monopoly rent. We develop this idea in a model of Bertrand price competition. In equilibrium, one firm enters the market and makes choices that are unpredictable to...

Abstract: This paper develops and tests a conceptual framework on the relationships between competition, time horizon and corporate social performance (CSP). We hypothesize that more intense competition discourages CSP by lowering the time horizon of companies. We test the hypothesis on a sample...

We consider consumers with the same reservation price, who desire to buy at most one unit of a good. Firms compete only in prices but there are other features firms cannot control that would eventually lead an agent to buy in one firm or another. We introduce such uncertainty in a model of a...

We analyze educational institutions’ incentives to set up demanding or lax curricula in duopolistic markets for education with endogenous enrolment of students. We assume that there is a positive externality from student achievement to the local economy. Comparing the case of regulated tuition...

This paper examines coalition-proof Nash equilibria (CPNE) of a mixed duopoly with price competition where the public firm meets all the demand coming to it. If the private firm is free to supply less than demand, then the unique CPNE involves the competitive price. If however the private firm...

In this note, we analyze the equilibrium outcomes of pricing games with product differentiation in relation with the extent of market coverage. It is a received idea in the IO literature that the horizontal and vertical models of product differentiation are almost formally equivalent. We show...

In this paper we investigate whether markets with heterogeneous network externalities can be locked-in by old technologies even if superior technologies are available. Heterogeneous network externalities are present when some consumers care more about the size of the market share of a good than...

This article examines the incentive to merge in a Bertrand competition model with generalized substitutability and price competition. The model suggests that acquisition of firms by their rivals can result in maximal concentration of the industry.
