报告内容摘要：This paper studies cross holding in a downstream Cournot oligopoly with different upstream market structures (competitive, monopolistic and oligopolistic). We find that when the upstream market is oligopolistic, the upstream suppliers will strategically respond to the downstream cross holding. This improves the profitability of cross holding, and firms thus engage in cross holding. Meanwhile the upstream suppliers' reaction also stimulates downstream production, which change the welfare implications of the cross holding. Particularly, when the upstream market consists of duopoly and the two firms engaged in cross holding (in downstream market) are supplied by different suppliers, the aggregate industry output increases, as well as the consumer welfare and social welfare. And the firm that is not involved in cross holding, suffers a loss from cross holding when it shares the supplier with the acquired firm in the case of a duopoly upstream market, i.e., the common free-rider in the literature becomes a victim of cross holding.
