Abstract: According to common wisdom, mergers between complementary-goods firms should not raise anti-competitive concerns. Regulatory authorities rarely challenge them indeed. In this paper, I offer an alternative perspective in a model of price-competition in a complementary oligopoly industry with differentiated goods. The sign of the change in the consumer surplus, after the merger between the quality leaders of the respective complementary goods, depends however upon the consumers' valuation distribution over these products. A family of elliptic-arc distributions, parameterized by the elliptic small semi-axis, is used to derive the result.
