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...

This paper analyses monopolistic third-degree price discrimination in the presence of consumption externalities within two separate markets. Assuming linear inverse demands, we investigate an associated change in social welfare (the sum of the consumers' surpluses and the producer's profit) with...

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 discuss the effect of personalized pricing on profits and welfare in a Hotelling model in which consumers can simultaneously purchase from both firms. We have the following results. If the additional gain from the second purchase (henceforth, the additional gain) is small, personalized...
