When one firm’s strategy affects other firms’ value, optimal executive incentives depend on whether shareholders have interests in only one or in multiple firms. Performance-sensitive contracts induce managerial effort to reduce costs, and lower costs induce higher output. Hence, greater...

We present a mechanism based on managerial incentives through which common ownership affects product market outcomes. Firm-level variation in common ownership causes variation in managerial incentives and productivity across firms, which leads to intra-industry and intra-firm cross-market...

A firm's incentives to innovate deteriorate when other firms benefit from its R&D activities without incurring a cost. We show under which conditions common ownership of firms can mitigate this impediment to corporate innovation, and test the model's empirical predictions. Common ownership...

We provide new facts about the cross-section and evolution of mergers and acquisitions for U.S. public firms. Using a general equilibrium model with a hedonic demand system and data on institutional ownership, we document that mergers are increasingly concentrated among firm pairs with a high...

We show theoretically and empirically that executives are paid less for their own firm’s performance and more for their rivals’ performance if an industry’s firms are more commonly owned by the same set of investors. Higher common ownership also leads to higher unconditional total pay. We...
