Revisiting the role of elasticity in multiproduct monopoly pricing

Anne-Christine Barthel

Economics Letters, 2018, vol. 167, issue C, 120-123

Abstract: This paper provides ordinal conditions on elasticities and Lerner indices which guarantee that a monopolist charges a higher price in one market relative to another. These improve upon shortcomings of traditional methods, which rely on the point-wise comparability of elasticities.
