Book Description
Price discrimination by consumer's purchase history is widely used in regulated industries, such as communication or utilities, both by incumbents and entrants. I show that such discrimination can have surprisingly negative welfare effects -- even though prices and industry profits fall, so does consumer surplus. Earlier studies that did not allow entrants to discriminate or assumed symmetric firms yielded sharply different results, the pro-competitive effect of price discrimination are stronger in these settings. Imposing a pricing constraint on incumbent's discrimination leads the entrant to discriminate more heavily, but still improves both consumer and producer welfare.
