The question of whether and how partial common-ownership links between strategically interacting firms affect firm behavior has been the subject of theoretical inquiry for decades. Since then, consolidation and increasing concentration in the asset-management industry has led to more pronounced...

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...

A fast-growing legal literature commenting on a set of empirical papers alleging anticompetitive effects of common ownership claims that the reported effects, if true, would imply that corporate executives violate their fiduciary duty: whereas acting in the interest of common owners can help...

These slides summarize the theoretical literature on horizontal common ownership concentration and its impact on competition, as presented at the FTC's hearings on common ownership and competition in December 2018. They are primarily based on this literature review:...

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...

The question of whether and how partial common-ownership links between strategically interacting firms affect firm objectives and behavior has been the subject of theoretical inquiry for decades. Since then, the growth of intermediated asset management and consolidation in the asset-management...

Many natural competitors are jointly held by a small set of large institutional investors. In the US airline industry, taking common ownership into account implies increases in market concentration that are 10 times larger than what is “presumed likely to enhance market power” by antitrust...

We document substantial time-series and cross-sectional variation in branch-level deposit account interest rates, maintenance fees, and fee thresholds, and examine whether variation in bank concentration helps explain variation in these prices. HHI alone is not correlated with any of the outcome...
