We examine price competition with homogeneous products in the presence of general common ownership arrangements allowing for different corporate control structures. Common ownership leads managers to internalize other firms profits. We show that equilibria with positive profits exist (including the monopoly out- come) when the manager places the same weight on the profit of her firm as on the average profit of all the other firms. This condition supports symmetric and asymmetric stakes and can arise as an equilibrium of a network formation game or a bargaining process.
