在寡头竞争市场环境下,生产完全互补产品的厂商可以通过谈判签约并使用“混合捆绑”策略进行竞争,如电信运营商与手机厂商共同推出的签约套餐和预付费套餐。针对这种行为,文章构建了一个包含两组互补品厂商的寡头博弈模型,研究混合捆绑销售契约对市场价格、厂商利润和社会福利的影响。研究表明:当只有一组厂商签订混合捆绑销售契约时,签约厂商能够从捆绑折扣中获得竞争优势,而竞争对手则被迫降低自己产品价格并在竞争中处于劣势;当两组厂商均签订混合捆绑销售契约时,围绕捆绑产品的竞争将使得捆绑折扣进一步提高,但各自的利润却下降了。然而当这种签约策略内生时,所有厂商将选择签订契约并进行捆绑销售,从而陷入“囚徒困境”。最终,在互补产品“纵向外部性”和系统产品“横向外部性”的共同作用下,混合捆绑销售契约提高了消费者剩余而降低了社会福利。基于本文分析,应该反对竞争政策对厂商谈判签订契约使用混合捆绑策略进行竞争的行为。文章的贡献在于从契约的角度研究厂商之间的捆绑销售策略,并运用统一的分析框架考察了不同契约结构下厂商实施捆绑销售的动机,对于深化捆绑销售的理论研究和完善竞争政策具有重要的借鉴意义。
