The Product Market Impact of Minority Stake Acquisitions
研究发现，收购竞争对手的少数股权会削弱产品市场竞争，导致产品价格和行业利润上升，尤其当进入壁垒较高时。
We show that partial equity ownership of a rival firm reduces product market competition. Acquisitions of a minority equity stake in rival firms are followed by higher output prices and higher industry profits, particularly when barriers to entry are high. Stock-price reactions of nonparticipating competitors of the acquirer and target are positive while announcement returns of customer firms are negative. Moreover, announcement returns of rivals are significantly higher and those of customers weakly lower when the customer industry is more competitive and when the acquirer and target are larger firms.
