Governance Measures

Measures

Key: Measure - Build - Sources - Paper

Note: Each paper seems to use one of three indices to measure corporate governance.

• Corporate Governance (anti-takeover provision or ATP) Indices - Gompers et al 2003 (GIM) uses 24 IRRC antitakeover provisions & adds one point to index for each provision that enhances managerial power. Bebchuk et al 2009 (BCF) takes only 6 of those provisions for its entrenchment index (staggered boards, limits to shareholder bylaw amendments, limits to shareholder charter amendments, supermajority requirements for mergers, poison pills, and golden parachutes - SDC M&A Database, acquirer has financial info thru Compustat and CRSP Daily Stock Price & Returns File, acquirer is included in Investor Responsibility Research Center (IRRC) of antitakeover provisions - Masulis et al 2011
• GIM Difference - Target GIM index less Bidder GIM index - IRRC - Wang et al 2009

Masulis et al 2011

@article{masulis2007corporate,
 title={Corporate governance and acquirer returns},
 author={Masulis, Ronald W and Wang, Cong and Xie, Fei},
 journal={The Journal of Finance},
 volume={62},
 number={4},
 pages={1851--1889},
 year={2007},
 publisher={Wiley Online Library},
 abstract={We examine whether corporate governance mechanisms, especially the market for corporate control, affect the profitability of firm acquisitions. We find that acquirers with more antitakeover provisions experience significantly lower announcement-period abnormal stock returns. This supports the hypothesis that managers at firms protected by more antitakeover provisions are less subject to the disciplinary power of the market for corporate control and thus are more likely to indulge in empire-building acquisitions that destroy shareholder value. We also find that acquirers operating in more competitive industries or separating the positions of CEO and chairman of the board experience higher abnormal announcement returns.}

Bebchuk et al 2009

@article{bebchuk2009matters,
 title={What matters in corporate governance?},
 author={Bebchuk, Lucian and Cohen, Alma and Ferrell, Allen},
 journal={Review of Financial studies},
 volume={22},
 number={2},
 pages={783--827},
 year={2009},
 publisher={Soc Financial Studies}
 abstract={We investigate the relative importance of the twenty-four provisions followed by the Investor Responsibility Research Center (IRRC) and included in the Gompers, Ishii, and Metrick governance index (Gompers, Ishii, and Metrick 2003). We put forward an entrenchment index based on six provisions: staggered boards, limits to shareholder bylaw amendments, poison pills, golden parachutes, and supermajority requirements for mergers and charter amendments. We find that increases in the index level are monotonically associated with economically significant reductions in firm valuation as well as large negative abnormal returns during the 1990–2003 period. The other eighteen IRRC provisions not in our entrenchment index were uncorrelated with either reduced firm valuation or negative abnormal returns.}

Wang et al 2009

@article{wang2009corporate,
 title={Corporate governance transfer and synergistic gains from mergers and acquisitions},
 author={Wang, Cong and Xie, Fei},
 journal={Review of Financial Studies},
 volume={22},
 number={2},
 pages={829--858},
 year={2009},
 publisher={Soc Financial Studies}
 abstract={We present evidence on the benefits of changes in control from mergers and acquisitions. We find that the stronger the acquirer's shareholder rights relative to the target's, the higher the synergy created by an acquisition. This result supports the hypothesis that acquisitions of firms with poor corporate governance by firms with good corporate governance generate higher total gains. We also find that the synergy effect of corporate governance is shared by target shareholders and acquiring shareholders, in that both target returns and acquirer returns increase with the shareholder-rights difference between the acquirer and the target.}
