their value (<strong>and</strong> to avoid myopic behavior), or because investors simply place higher valuations on such firms, or because it is in the managers’ own self interests. These possibilities differ in terms of their predictions for relations between ESG or CSR performance <strong>and</strong> firm’s operating performance, operational efficiency or revenues, managerial compensation, trading by institutional investors, <strong>and</strong> ultimately, firm value. We examine these relations in a sequence of tests in hopes of better underst<strong>and</strong>ing the typical motive behind firms’ ESG decisions <strong>and</strong> the market’s response to those decisions. Using KLD’s important index of firms’ environmental, social <strong>and</strong> governance strengths, concerns, <strong>and</strong> the net of those two, we find little evidence that “good” ESG behaviors are typically pursued by self-interested managers at the expense of shareholders. Instead, it appears that ESG firms operate more efficiently, generate greater returns on assets, <strong>and</strong> have higher valuations. Further, it does not seem to be the case that managers implementing stronger ESG policies are more highly compensated than their peers, after controlling for st<strong>and</strong>ard determinants of compensation. This suggests that if CEOs are using ESG policies to extract rents, it is not linked to average profitability <strong>and</strong> expenses, <strong>and</strong> they are not also extracting rents via higher compensation. Interestingly, while these results are consistent with the idea that firms benefit from investing in stronger ESG policies, the mechanism by which these practices are reflected in stock prices is unclear. One natural c<strong>and</strong>idate, increased institutional investment, does not appear to be borne out in the data. If anything, it appears that on aggregate institutions own less, <strong>and</strong> sell more, of firms that have greater scores along the environmental, social, <strong>and</strong> governance dimensions, at least as measured by KLD through 2007. We do find some exceptions to these overall finding in the case of KLDs governance rankings. Specifically, there is evidence 23
suggesting that institutional investors may avoid firms with more governance concerns, <strong>and</strong> that institutions may also successfully pressure some firms into adopting more shareholder-friendly policies. 24
