| Sumario: | We propose a model with two markets to analyze the welfare implications of price discrimination with quality differences. In each market a local firm that operates in that market only competes against a global firm that operates in both markets. Local firms produce higher-quality goods than the global firm. If the quality levels of the local firms' products are the same, price discrimination is never welfare-decreasing. If they differ, discrimination is welfare-increasing if quantity increases. Because of a positive allocation effect of price discrimination, there are parameter values such that welfare increases while total output decreases with price discrimination. ( JEL D43, D60)
