We study a two-period model of behavior-based price discrimination in Fudenberg and Tirole (2000) but allow firms to make product choice in the first period. We show that the only possible equilibrium involves maximal differentiation. This is in contrast to Choe et al. (2018) where equilibrium...

This paper investigates how the formation of larger buyers affects a supplier's profits and, by doing so, his incentives to undertake non-contractible activities. We first identify two channels of buyer power, which allows larger buyers to obtain discounts. We subsequently examine the effects of...

We consider a downstream oligopoly model with one dominant and several fringe retailers, who purchase a manufacturing product from a monopoly supplier. We then examine how the supplier's outside option influences the relation between the dominant retailer's bargaining power and the equilibrium...

We consider a downstream oligopoly model with one dominant and several fringe retailers who purchase a manufacturing product from a monopoly supplier. We examine how contract type influences the relationship between the dominant retailer's bargaining power and the equilibrium retail price. If...

In Japan, TV platforms regulate themselves as to the length of the advertisements they air. Using modified Hotelling models, we investigate whether such self-regulation improves consumer and social welfare or not. When all consumers choose a single TV program (the utility functions of consumers...

We consider a downstream oligopoly model with one dominant and several fringe retailers, who purchase a manufacturing product from a monopoly supplier. We then examine how the supplier's outside option influences the relation between the dominant retailer's bargaining power and the equilibrium...

We re-examine the view that a ban on price discrimination in input markets is particularly desirable in the presence of buyer power. This argument crucially depends on an inverse relationship between downstream firms' profits and the uniform input price. Assuming different input efficiencies...

This paper studies the relationship between horizontal product differentiation and the welfare effects of third-degree price discrimination in oligopoly. By deriving linear demand from a representative consumer´s utility and focusing on the symmetric equilibrium of a pricing game, we...

We study a model of behavior-based price discrimination where firms can agree to share customer information that can be used for personalized pricing. We show that firms are better off sharing customer information as it softens up-front competition when they gather information, consumers are...

We consider the spatial competition between two traditional physical (or offline) retailers and an Internet (or online) retailer where the efficiency of the latter differs from that of the former. We assume consumers are heterogeneous across two dimensions: (i) the costs of traveling to either...
