Summary:
Review of Finance, Volume 26, Issue 6, November 2022
This article shows how sustainable investing—through the joint practice of exclusionary screening and environmental, social, and governance (ESG) integration—affects asset returns. The author develops an asset pricing model with partial segmentation and heterogeneous preferences. He characterizes two exclusion premia generalizing Merton’s (1987) premium on neglected stocks and a taste premium that clarifies the relationship between ESG and financial performance.
Focusing on US stocks, he estimates the model by applying it to sin stocks as excluded assets and using the holdings of green funds to proxy for environmental integration. The average annual exclusion effect is 2.79% for the period 1999–2019. Although the annual taste effect ranges from –1.12% to + 0.14% across industries for 2007–19, the taste effect spread between the top and bottom terciles of companies within each industry can exceed 2% per year.
Finally, he estimates and explain the dynamics of these premia.
