"A Sustainable Capital Asset Pricing Model (S-CAPM): Evidence from green investing and sin stock exclusion"



I demonstrate how sustainable investing through financial exclusion and environmental, social and governance (ESG) screening affect asset prices. I develop an asset pricing model with partial segmentation and heterogeneous beliefs. I characterize two exclusion premia generalizing Merton (1987)'s premium on neglected stocks and a taste premium that disentangles the link between ESG and financial performance. By constructing an instrument that captures sustainable investors' tastes for green firms, I estimate this model applied to green investing and sin stock exclusion using U.S. data. The model has substantial explanatory power for the cross-section of stock returns and outperforms the four-factor model.
