    Growing adoption of ESG investing after 2003 generates a new "friction" that affects the efficiency of stock markets. Socially responsible institutional investors tend to under-react to mispricing signals when they contradict the investors' preference for ESG performance. This leads to predictability of returns. 
  • Smart Beta, 'Smarter' Flows

    We examine the impact of smart beta equity exchange-traded funds (ETFs) on how investors evaluate active mutual fund performance. We find that when smart beta ETFs are actively traded, mutual fund flows become “smarter”, with a higher sensitivity to alphas from multi-factor models. The dominance of the CAPM alpha weakens and even disappears. Our findings highlight the importance of financial innovation in shaping investor behavior and are not explained by alternatives such as investor learning because the results are driven by sophisticated investors. We document consistent evidence using international data and a cross-country analysis.
