Corporate Governance and Firm Operating Performance

Using a unique dataset provided by Institutional Shareholder Services (ISS), we relate 51 governance provisions to firm operating performance as proxied by return on assets and return on equity. We show that seven (six) governance provisions are significantly and positively related to return on assets (equity) using at least two of three econometric approaches. We identify 10 corporate governance provisions that are positively linked to return on assets, return on equity or both using at least two of our three econometric approaches. Nine of the corporate governance provisions we examine have recently been mandated by the three major U.S. stock exchanges but only one of them, nominating committee is comprised solely of independent outside directors, is significantly and positively related to firm operating performance. Our results reveal that the corporate governance reforms recently mandated by the three major U.S. stock exchanges are not more closely linked to firm operating performance than are those not so mandated
