摘要 Abstract of the Paper	We investigate the stability of common ownership arrangements. In a duopolistic market, the owner of a firm acquires a non-controlling share in the rival firm. Then, the acquirer of the minority share considers reselling the share to an investor. Common ownership is stable and the acquirer retains part of the share when there is asymmetry in the production costs of the firms. Common ownership is more likely to be stable as the initially acquired share increases. The welfare effects of the stable common ownership scheme depend also on the cost-asymmetry.
