I show that such discrimination can have surprisingly negative welfare e ects { even though prices and industry pro ts fall, so does consumer surplus. Earlier studies that did not allow entrants to discriminate or assumed symmetric rms yielded sharply di erent results, the pro{competitive e ect 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.
