题目:Does aftermarket monopolization facilitate upstream collusion?
摘要:This paper explores the stability of collusion among upstream firms selling to downstream retailers with an aftermarket. Consumer lock-in in this aftermarket has two effects. Firstly, it restricts the size of the aftermarket, which a deviating firm can capture from its rivals. Secondly, it limits the severity of punishments that act as a threat against deviation. We show that the second effect dominates the first one and thus collusion is less stable. Our results are robust when upstream firms supply parts using two-part tariffs or when the downstream aftermarket is asymmetric, with a downstream firm selling a generic substitute.
