Experienced and Novice Investors: Does Environmental Information Influence Investment Allocation Decisions?

This paper examines the effect of environmental information on investment decisions. The results are based on an experiment in which groups of investors (varied by experience) were asked to make short- and long-term investment allocation decisions based on financial information and on supplementary environmental information (varied between cases). The results suggest that environmental information disclosure influences investment allocation decisions. The results also suggest that potentially mitigating factors such as the investment horizon and the experience level of investors affect investment allocation decisions, but the predicted main effect of positive environmental information holds across different investment horizons and investor types. Hence, the results are not attributable to interaction effects. Interestingly, compared to other company information, environmental information is not rated as being very important by participating subjects even though the results suggest that it influences investment decisions.

How Well do Social Ratings Actually Measure Corporate Social Responsibility?

Ratings of corporations’ environmental activities and capabilities influence billions of dollars of “socially responsible” investments as well as some consumers, activists, and potential employees. In one of the first studies to assess these ratings, we examine how well the most widely used ratings—those of Kinder, Lydenberg, Domini Research & Analytics (KLD)—provide transparency about past and likely future environmental performance. We find KLD “concern” ratings to be fairly good summaries of past environmental performance. In addition, firms with more KLD concerns have slightly, but statistically significantly, more pollution and regulatory compliance violations in later years. KLD environmental strengths, in contrast, do not accurately predict pollution levels or compliance violations. Moreover, we find evidence that KLD’s ratings are not optimally using publicly available data. We discuss the implications of our findings for advocates and opponents of corporate social responsibility as well as for studies that relate social responsibility ratings to financial performance
