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 identify six corporate governance provisions that are significantly and positively linked to return on assets, return on equity or both using at least two of our six regressions. We examine nine governance provisions that have been recently mandated by the three major U.S. stock exchanges, and we find none of them to be significantly and positively related to firm operating performance. Our results reveal that the governance provisions recently mandated by the U. S. stock exchanges are less closely linked to firm operating performance than are those not so mandated.
