We examine a model of a monopolist selling to two segments of consumers with different preferences for quality. We show that if the firm is unable to price discriminate between the segments, then there is less investment in quality. We find that both consumer segments, and society overall, may suffer if the firm is unable to price discriminate. We extend the model to duopoly competition, and find that our results still hold.
