Environmental, social, and governance (ESG) investing is synonymous with sustainable investment for socially responsible investors. Unfortunately, the diversity of ESG investing remains unattended amidst the growth in ESG literature, as the academic literature focuses dominantly on measuring performance. An understanding of a wide range of subjects entailing ESG is required before future research on ESG investing is performed. To overcome the challenge, this systematic literature review uses bibliometric mapping to reveal four significant research themes within the ESG investing literature: investor (...) behavior and motivations for ESG investing; cost and risk mitigation in ESG investing; portfolio screening and ESG investing; and ESG performance. The review critically examines each theme and broadens the research agenda for future studies. In addition to the significant themes, this paper also discusses theoretical and recent research trends in the ESG investing literature. The review identifies clashes and crossovers between these themes to appropriately interpret one theme using another and emphasizes the heterogeneity in ESG investing. Lastly, discussion over concerns and criticisms of ESG investing highlights greenwashing as a major cause of concern for investors. (shrink)

In our study, we examine the association between hedge fund activism and a target firm’s corporate social responsibility (CSR) activities and whether activists can promote socially responsible investments while upholding shareholders’ interests. Using different matched samples, we find a strong positive association between the target firm’s CSR in the year before it is targeted by activists and its probability of being targeted by a hedge fund. Classifying hedge fund activists into socially and non-socially responsible funds based on their objectives, we (...) find that both give similar level of consideration to a firm’s CSR activities when initiating campaigns. Similar to DesJardine and Durand (DesJardine and Durand, Strategic Management Journal 41:1054–1082, 2020), we demonstrate that hedge funds have, on average, a negative impact on target firms’ CSR in the years following the initial investments. Complementary to DesJardine and Durand (DesJardine and Durand, Strategic Management Journal 41:1054–1082, 2020), we compare the two types of hedge funds and find an asymmetric effect of the hedge funds’ campaigns. Socially responsible hedge fund campaigns are associated with a large _increase_ in their target’s CSR, whereas non-socially responsible hedge funds _decrease_ this measure in their target. Finally, we find that target firms exhibit a long-term improvement in future stock returns and profitability. These findings provide evidence that certain types of activists, such as socially responsible funds, promote both _stakeholder_ and _shareholders’_ long-term interests. (shrink)
