Shareholder Activism Through the Proxy Process

This paper provides evidence on the corporate governance role of shareholder-initiated proxy proposals. Previous studies debate over whether activists use proxy proposals to discipline firms or to simply advance their self-serving agendas, and whether proxy proposals are effective at all in addressing governance concerns. Using the largest sample yet examined as well as extensive controls for governance quality, we find that activists use the proxy process as a disciplinary mechanism, and as such are valuable monitoring agents. Moreover, proposal announcements in the proxy statements have positive stock price effects, and both the market and the voting shareholders respond as much to the target firm’s governance quality as to the proposal’s objective and sponsoring shareholder. We address the endogeneity of target selection and proposal success using sample selection models. We conclude that shareholder proposals have nontrivial control benefits, countering arguments that they should be restricted by the SEC
