Cartel stability under quality differentiation
Research output: Contribution to journal › Article › Academic › peer-review
This note considers cartel stability when the cartelized products are vertically differentiated. If market shares are maintained at pre-collusive levels, then the firm with the lowest competitive price-cost margin has the strongest incentive to deviate from the collusive agreement. The lowest-quality supplier has the tightest incentive constraint when the difference in unit production costs is sufficiently small. (C) 2018 Elsevier B.V. All rights reserved.
