Abstract: I examine the case of a firm that practices both second-degree and third-degree price discrimination. I present a model showing conditions under which the premium for higher quality can either rise or fall as the firm implements group pricing. I then use new data from a regional airline to estimate how the two kinds of price discrimination interact, and how each is affected by changes in competition. I establish three key results, all new to the literature. First, in different markets, the two kinds of price discrimination can either offset or reinforce each other, in a manner that fits the model's predictions. Second, inter-temporal differences in prices are purely driven by price discrimination, rather than by scarcity pricing. Third, competition increases the extent of both kinds of price discrimination.
