S6 Ep8: Applying economics (not gut feel) to ESG

Episode Summary

Executive Summary: The episode argues that ESG is important enough to deserve rigorous, mainstream economic analysis rather than urgency-driven intuition. Alex Edmonds contends that many common ESG beliefs confuse short-termism with shareholder value, overstate the benefits of ESG metrics, misread shareholder primacy, and neglect general-equilibrium effects, while suggesting that long-term incentives and existing finance theory can better support effective ESG action.

Main Topics: ESG should be guided by mainstream economics (Priority: 5/5): Edmonds argues that ESG is not so novel that it requires abandoning established economic frameworks; decades-old tools can be applied to long-term ESG decisions. Short-termism vs. shareholder value (Priority: 5/5): The discussion distinguishes short-term performance pressure from shareholder value, which Edmonds says is inherently long-term and not the root problem. Stakeholder capitalism and policy trade-offs (Priority: 4/5): The coal mine example is used to show that not every controversial project is a clear ESG failure; jobs, legality, regulation, and societal trade-offs matter. ESG doublethink and equilibrium (Priority: 5/5): Edmonds criticizes claims that ESG both lowers cost of capital and raises investor returns, arguing investors must acknowledge trade-offs and equilibrium constraints. Limits of ESG metrics (Priority: 5/5): Improving firm-level ESG scores can be misleading if companies shift pollution elsewhere or sell dirty assets rather than reducing harm overall. Executive pay and performance measures (Priority: 4/5): He rejects pay tied to narrow ESG scores or earnings per share, favoring long-term stock price as a broader incentive that captures multiple dimensions of performance. Risk and investment decisions (Priority: 3/5): The episode notes that idiosyncratic risk should not deter socially valuable projects like carbon capture if the risk is not correlated with the broader market.

Key Arguments: ESG is important, but that is precisely why strategy should be grounded in tested economic principles rather than gut feel. Shareholder value is a long-term concept; short-termism is the real issue, so the policy fix should target CEO horizons rather than weaken shareholder primacy. A controversial project such as a coal mine cannot automatically be blamed on shareholder primacy because many other factors—regulation, jobs, and product type—matter. ESG investing claims can be internally inconsistent when they promise both higher investor returns and a lower cost of capital; in equilibrium, these cannot both be true at once. Firm-level ESG metric improvements can be cosmetic if firms export pollution or shift assets to worse owners, so aggregate impacts must be considered. Paying executives on narrow ESG indicators can distort behavior and encourage metric gaming; long-term stock price is a better broad incentive because it reflects many performance dimensions. Idiosyncratic risk should not automatically block ESG-related investment if the project’s risk is uncorrelated with the market and the social value is high. Many ESG problems can be addressed by properly applying existing economics, meaning regulators and investors may not need entirely new theories to act effectively.

Data Points: Number of examples in the paper: 10 - Edmonds says the article lists 10 ways conventional ESG wisdom may be misguided. Alternative ideas considered: 12 or 13 - He says he initially thought of about 12 or 13 examples before narrowing to 10. Potential total examples: 20 or 30 - Edmonds says he could probably have found 20 or 30 examples in total. Approximate share of existing practice applicable to ESG: 70%–90% - He argues that most ESG decisions can be handled by applying existing economic frameworks properly. Approximate share of existing practice applicable to ESG: 80% - He offers another rough estimate that about 80% of ESG issues can be addressed using established methods. Long-term CEO share-holding horizon: 7 to 10 years - As a policy fix for short-termism, he suggests CEO shares could vest or remain illiquid for seven to ten years. Paper discussion reference: Discussion paper 17908 - The transcript identifies the CEPR paper number for the article. Author working on ESG: Nearly 20 years - Edmonds says he has been working on ESG for nearly 20 years. Potential investor impact claim: 21 times more powerful - He criticizes a claim from Make My Money Matter that making pensions greener is 21 times more powerful than giving up flying, going veggie, or changing electricity supply.

Pivotal Quotes: "ESG is extremely important... the reason for writing this article is not that I think ESG is unimportant. It's in contrary. ESG is so important that we need to make sure that we get it right." — Alex Edmonds: He explains that his critique is meant to improve ESG strategy, not reject ESG itself. "Shareholder value is an inherently long-term concept." — Alex Edmonds: He uses this to distinguish shareholder value from short-term performance pressure. "You can have either one or the other, but it's not fair to claim both." — Alex Edmonds: He is discussing the contradiction in claiming ESG both lowers cost of capital and raises investor returns.

Implications: Listeners should treat ESG as a serious long-term optimization problem, not a branding exercise. Firms, investors, and regulators should use established economics, focus on aggregate outcomes, and avoid metric-gaming, short-termism, and contradictory claims about ESG performance.
