Alex Edmans: Growing the Pie: A Different Take on ESG (EP.192)

Episode Summary

Executive Summary: Professor Alex Edmans argues that ESG should be judged by whether it grows a company’s total social value (“the pie”), not by box-ticking metrics. He distinguishes intrinsic value creation from instrumental compliance, critiques divestment and overclaimed impact, and shows—via employee satisfaction and sentiment research—that material, qualitative factors can be mispriced and matter for returns.

Main Topics: Grow the Pie vs. Maximize Profits (Priority: 5/5): Edmans explains that companies create social value shared among investors, workers, customers, and government. Treating employees well can expand the pie and raise profits rather than merely redistribute value. Intrinsic ESG vs. Box-Ticking ESG (Priority: 5/5): He contrasts meaningful, qualitative sustainability efforts with narrow quantitative checklists, arguing that ESG-by-numbers misses important factors like culture, meaning, and psychological safety. Role of Investors, Engagement, and Divestment (Priority: 5/5): Edmans argues large asset managers should not usurp government’s role, and that engagement/tilting often works better than exclusionary divestment for driving change. Materiality and Mispricing of Employee Satisfaction (Priority: 5/5): He defends his research showing employee satisfaction predicts returns, especially when the issue is material to the industry and when qualitative measures capture what standard metrics miss. Limits of ESG Claims and Performance (Priority: 4/5): He rejects the notion that all sustainable investing beats the market, warning against contradictory claims that sustainability lowers cost of capital and raises expected returns simultaneously. Behavioral Finance and Music/Sentiment Research (Priority: 4/5): He describes studies linking happier music listening to stronger equity returns and higher equity-fund flows, using this as evidence of market inefficiency and investor emotion. Academic Integrity and Evidence Standards (Priority: 4/5): He emphasizes peer review, replication, and searching for contrary evidence as the best defense against selective reporting and ESG marketing spin.

Key Arguments: ESG should be judged on whether it creates net social value, not whether it satisfies a numeric checklist. Many important sustainability factors are qualitative and cannot be captured well by standardized metrics. Friedman’s famous profit-maximization argument is more nuanced than commonly portrayed, but still too instrumental and too limited for some externalities and intangible investments. Government should set the rules on broad social issues; investors should focus on issues the market or regulation misses, especially qualitative culture and employee well-being. Divestment alone usually does not deprive firms of capital because shares are sold to another buyer; engagement or tilting is more effective for influence. Exclusionary ESG funds may satisfy values, but they should not claim they are changing the company unless they can show actual causal impact. The average ESG fund does not beat the market over long horizons, and claims that sustainable investing always produces higher returns are inconsistent. Employee satisfaction generated significant abnormal returns in Edmans’s study, suggesting markets underprice human-capital quality and culture. Material ESG issues matter; ESG performance appears to pay off mainly when the issue is financially material to the industry. Peer-reviewed evidence should be trusted more than marketing-driven reports or selective studies; one should actively look for evidence in the opposite direction. Behavioral evidence from music and sports studies supports the idea that markets are influenced by emotion, not just fundamentals. A finance professor’s role is to create and disseminate knowledge, not merely publish academic papers.

Data Points: Four-factor alpha: 2.3% to 3.8% per year - Edmans’s 2011 Journal of Financial Economics paper on employee satisfaction and stock returns Compounded return equivalent of alpha: 89% to 184% compounded - Same employee-satisfaction paper, illustrating the economic magnitude of the alpha Original sample length: 28 years - The Best Companies to Work for in America data used in the employee satisfaction study Out-of-sample replication period: 10 additional years - Independent replication of the employee-satisfaction findings after the original paper Countries with workplace-list data: 45 countries - Global extension of the best-companies-to-work-for data set Countries with sufficient domestic firms for testing: 30 countries - Subset used to avoid contamination from multinational effects Best-performing large-cap fund claim: Best over 1-, 2-, 5-, and 10-year periods - Morningstar study on the Parnassus Endeavour Fund mentioned by Edmans Parnassus Endeavour Fund fee: 88 basis points - Discussed by Ben Felix while evaluating the fund High pay ratio example: $66 million - Bob Iger’s pay mentioned in the executive compensation discussion Pay ratio example: Over 1,000x average worker pay - Used to illustrate executive compensation disparities Academic research sensitivity: 90 regressions, zero significant - Example of a flawed diversity paper referenced during the discussion

Pivotal Quotes: "What I call it is not just ESG by numbers, but trying to think that you can do it by numbers. I think that is as dangerous as having a teaching by numbers approach." — Alex Edmans: Explaining why qualitative ESG factors should not be reduced to checklists "You hit the target, but miss the point." — Alex Edmans: Critiquing metric-driven sustainability programs that ignore what really matters "The social responsibility of business is to increase its profits." — Benjamin Felix quoting Friedman: Opening discussion of Milton Friedman’s framework and Edmans’s response

Implications: Listeners should be skeptical of simplistic ESG scores and marketing claims. The strongest investing opportunities may come from material, qualitative factors like culture and employee treatment, while genuine social impact often requires engagement, regulation, or personal value choices—not just divestment.
