Martin Schmalz, Oxford: Common-Ownership Concentration and Corporate Conduct
Department seminar. Martin Schmalz is an Associate Professor of Finance, Saïd Business School, at University of Oxford. He will present his paper: "Common-Ownership Concentration and Corporate Conduct".
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 sector has led to more pronounced common ownership links at the beneficial-owner level. Recent empirical research has provided evidence consistent with the literature's prediction that common ownership concentration (CoOCo) can affect product market outcomes. The resulting antitrust concerns have received worldwide attention. However, because CoOCo can change the objective function of the firm, the potential implications span all fields of economics that involve corporate conduct, including corporate governance, strategy, industrial organization, and financial economics. This article connects the papers establishing the theoretical foundations, reviews the empirical and legal literatures, and discusses challenges and opportunities for future research.
