E-MailThis post relates to a Program on Corporate Governance study published by Lucian Bebchuk, Alma Cohen and Allen Ferrell, What Matters in Corporate Governance, available here and discussed on the Forum here. Lucian Bebchuk is James Barr Ames Professor of Law, Economics, and Finance and Director of the Program on Corporate Governance, Harvard Law School. Alma Cohen is Professor of Empirical Practice, Harvard Law School. Allen Ferrell is Harvey Greenfield Professor of Securities Law, Harvard Law School.
In a study issued by the Harvard Law School Program on Corporate Governance, Bebchuk, Cohen, and Ferrell (2009), put forward a corporate governance index – the Entrenchment Index (E Index). The study has had substantial influence on subsequent research work. According to Google Scholar citations data, as of the end of 2019, the study was cited by 2,539 research papers; a list of these papers is available here. Furthermore, a review of these research papers has identified more than 1,000 studies that applied and empirically used the E index.
A list of 1,002 empirical studies using the E index in their empirical analysis is available here. The list includes many empirical studies published in:
- Leading journals in finance such as The Journal of Finance, The Journal of Financial Economics, and The Review of Financial Studies;
- Leading journals in economics such as the Journal of Political Economy and the Review of Economics and Statistics;
- Leading journals in law and economics such as the Journal of Law and Economics and Journal of Law, Economics, and Organization; and
- Leading journals in accounting, such as the Journal of Accounting and Economics, Journal of Accounting and Public Policy, and The Accounting Review.
The Bebchuk, Cohen, & Ferrell study was first circulated in 2004 and was published in 2009 in the Review of Financial Studies. The study identified six corporate governance provisions as especially important, demonstrated empirically the significance of these provisions for firm valuation, and put forward an “Entrenchment Index” based on these six provisions.
The study putting forward the Entrenchment Index is available here.
