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...

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 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...

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...

We study a duopoly model where each firm chooses personalized prices for its targeted consumers, who can be active or passive in identity management. Active consumers can bypass price discrimination and have access to the price offered to non-targeted consumers, which passive consumers cannot....
