There is a growing interest in using the discrete choice approach to study oligopolistic competition under product differentiation, and a prominent discrete choic model is the multinomial logit. Here we analyze various aspects of the logit in this context. We first show that the predictions of...

Thie paper proves the existence of a symmetric equilibrium with multiproduct firms using a nested logit model of demand. The demand model is parametrized by two variable which characterize different dimensions of preference variety. These reflect intragroup heterogeneity and intergropu...

) and Shaked and Sutton (1982). Finally, despite the fact that the equilibrium concept is open-loop, all but the introductory price of the high quality good converge to marginal cost in the limit as firms can change prices arbitrarily frequently.

This paper reports two laboratory studies designed to study the impact of public informationabout past departure rates on congestion levels and travel costs. Our experimental design isbased on a discrete version of Arnott, de Palma, and Lindsey’s (1990) bottleneck model wheresubjects have to...

This paper examines simple parimutuel betting games under asymmetric information,with particular attention to differences between markets in which bets are submittedsimultaneously versus sequentially. In the simultaneous parimutuel betting market, all(symmetric and asymmetric) Bayesian-Nash...
