内容摘要：Partial ownership interests, whereby a firm acquires a share of a competitor's profits, have been growing prevalence across various industries. This paper demonstrates that instead of fostering collusion in repeated oligopolidtic competition with differentiated products, such partial ownership interests actually impede collusion. This effect holds true as long as the acquiring firms themselves are not subject to partial acquisition. The anti-collusive outcome underscores the importance of product differentiation as a critical determinant influencing the competive impact of partial ownership interests. Moreover, it provides a compelling rationale for why partial ownership interests do not raise antitrust concerns.
