AI Personality Extraction from Faces: Labor Market Implications

The Quarterly Journal of Economics Reject & Resubmit
Abstract
Human capital—encompassing cognitive skills and personality traits—is central for labor-market success, yet personality remains difficult to measure at scale. Leveraging advances in AI and comprehensive LinkedIn microdata, we extract the Big 5 personality traits from facial images of 96,000 MBA graduates, and demonstrate that this novel “Photo Big 5” predicts school rank, job matching, compensation, job transitions, and career advancement. The Photo Big 5 provides predictive power comparable to race, attractiveness, and educational background, and is only weakly correlated with cognitive measures such as test scores. We show that individuals systematically sort into occupations where their personality traits are valued and earn higher wages when traits align with occupational demands. While the scalability of the Photo Big 5 enables new academic insights into the role of personality in labor markets, its growing use in industry screening raises important ethical concerns regarding statistical discrimination and individual autonomy.

Valuation Models

Abstract
Valuation models lie at the core of both financial theory and practice, yet we lack systematic evidence on how professionals value assets, which models perform best, and why. To make progress on these questions, we analyze valuation models in 1.1 million equity analyst reports. While, on average, simpler multiples-based models generate more accurate forecasts than more complex discounted cash flow (DCF) models, this masks important heterogeneity: skilled analysts produce superior forecasts with DCF models, especially for hard-to-value firms, underscoring the importance of expertise when employing complex models. To establish that model-specific expertise matters, we exploit a quasi-exogenous shock that forced some analysts to switch valuation models, and show that their forecast accuracy subsequently declines relative to analysts with established experience using the new approach. This highlights a fundamental trade-off between simplicity and sophistication in valuation, where optimal method choice depends on analyst characteristics, such as skill. Finally, given their unconditional superior performance, we study how analysts determine multiples. Analysts use historical, current, and peer-based reference points to contextualize their choice of multiples, but they do not use these benchmarks mechanically when determining their prices. Moreover, we show that sensitivity analyses have become increasingly common, bull and bear scenarios are asymmetric and account for greater downside risk, and their inclusion is associated with more conservative forecasts.

Mental Models and Financial Forecasts

The Quarterly Journal of Economics Reject & Resubmit
Jack Treynor Prize 2025 · Charles Brandes Prize 2025
Abstract
We uncover the mental models financial professionals use to explain their quantitative forecasts, and show how they shape beliefs and return predictability. Using the near-universe of 2.1 million equity analyst reports, we collect the valuation methods analysts adopt to compute their price targets, together with their reasoning, measured as attention to topics, and their associated valuation channels, time horizons, and sentiments. To validate the reliability of our output, we introduce a multi-step LLM prompting strategy and new diagnostic tools. Consistent with a model of top-down and bottom-up attention, we then uncover three sets of facts. First, analysts’ mental models are sparse and rigid, and the choice of attention allocation and valuation methods are jointly determined by both analyst- and firm-characteristics. Second, analysts’ reasoning translates into their quantitative forecasts. Both attention and valuation methods contribute to differences in valuations over time and across analysts, but variation in attention plays a bigger role. Third, we study the extent to which different topics contribute to over and underreaction to information, and show how biases in analysts’ reasoning are reflected in asset prices. Analysts underreact to macroeconomic topics, and overreact to firm-related topics, and this contributes to return predictability.

The Formation of Very Long-Run Firm Growth Expectations

Best Paper Award, Mid-Atlantic Research Conference in Finance (MARC) 2024
Abstract
We study how forecasters form beliefs about very long-run firm growth using data on terminal growth rate (TGR) expectations, textual discussions, and demographics. TGR expectations are distinct from shorter-horizon beliefs, correlated with firms’ long-run growth, and uncontaminated by expected returns. Compared to short-run expectations, persistent forecaster heterogeneity carries more weight, accounting for 69% of explained variation in TGR. Local extrapolation is strongest in distant and unfamiliar contexts. TGR heterogeneity reflects differential textual emphasis on macroeconomic, industry, and geographic topics, yielding a unifying insight: when outcomes are distant and fundamental anchors are weak, individual background and experience dominate in shaping beliefs.

Prosociality and Layoffs

Abstract
Standard models treat layoffs as routine input adjustments; yet managers consistently describe them as the hardest and most painful decisions. Using novel U.S. data on layoffs, we document several patterns standard models struggle to explain, but that are consistent with empathy-driven prosocial motives. First, layoffs impose a personal health toll on managers, significantly reducing their lifespan. Second, CEOs’ layoff aversion increases over the course of their tenure. Third, layoff aversion intensifies when the consequences for employees are more severe and when CEOs are socially or geographically closer to workers. Finally, layoff aversion is most pronounced among CEOs with empathy-related traits.

Excess Commitment in R&D

The Review of Financial Studies 2026 · 39(7) · 2179–2221
Abstract
We document that firms exhibit “excess” commitment to R&D projects and examine its consequences for innovation outcomes. Using detailed data on pharmaceutical firms’ clinical trial projects, we find that trial delays, empirically uncorrelated with multiple project-quality measures, substantially reduce firms’ subsequent project-termination propensity. This result remains robust when we use variation in clinical trial site congestion to instrument for unexpected delays. Excess commitment intensifies when CEO compensation has greater stock-price sensitivity and the CEO is responsible for the project’s initiation. Our findings have broader implications: delay-driven commitment reduces new drug project initiations, with further evidence suggesting efficiency losses for firms.

CEO Stress, Aging, and Death

The Journal of Finance 2025 · 80(6) · 3401–3442
Abstract
We assess the long-term effects of managerial stress on aging and mortality. Using a difference-in-differences design, we apply neural network–based machine-learning techniques to CEOs’ facial images and show that exposure to industry distress shocks during the Great Recession produces visible signs of aging. We estimate a one-year increase in “apparent” age. Moreover, using data on CEOs since the mid-1970s, we estimate a 1.1-year decrease in life expectancy after an industry distress shock, but a two-year increase when antitakeover laws insulate CEOs from market discipline. The estimated health costs are significant, both in absolute terms and relative to other health risks.

In Too Deep: The Effect of Sunk Costs on Corporate Investment

The Journal of Finance 2025 · 80(3) · 1593–1646
Abstract
Sunk costs are unrecoverable costs that should not affect decision making. I provide evidence that firms systematically fail to ignore sunk costs and that this leads to significant investment distortions. In fixed-exchange-ratio stock mergers, aggregate market fluctuations after parties enter into a binding merger agreement induce plausibly exogenous variation in the final acquisition cost. These quasi-random cost shocks strongly predict firms’ commitment to an acquired business following deal completion, with an interquartile cost increase reducing subsequent divestiture rates by 8% to 9%. Consistent with an intrapersonal sunk cost channel, distortions are concentrated in firm-years in which the acquiring CEO is still in office.

Behavioral Corporate Finance: The Life Cycle of a CEO Career

Oxford Research Encyclopedia of Economics and Finance 2020
Abstract

One of the fastest-growing areas of finance research is the study of managerial biases and their implications for firm outcomes. Since the mid-2000s, this strand of behavioral corporate finance has provided theoretical and empirical evidence on the influence of biases in the corporate realm, such as overconfidence, experience effects, and the sunk-cost fallacy. The field has been a leading force in dismantling the argument that traditional economic mechanisms—selection, learning, and market discipline—would suffice to uphold the rational-manager paradigm. Instead, the evidence reveals that behavioral forces exert a significant influence at every stage of a chief executive officer’s (CEO’s) career. First, at the appointment stage, selection does not impede the promotion of behavioral managers. Instead, competitive environments oftentimes promote their advancement, even under value-maximizing selection mechanisms. Second, while at the helm of the company, learning opportunities are limited, since many managerial decisions occur at low frequency, and their causal effects are clouded by self-attribution bias and difficult to disentangle from those of concurrent events. Third, at the dismissal stage, market discipline does not ensure the firing of biased decision-makers as board members themselves are subject to biases in their evaluation of CEOs.

By documenting how biases affect even the most educated and influential decision-makers, such as CEOs, the field has generated important insights into the hard-wiring of biases. Biases do not simply stem from a lack of education, nor are they restricted to low-ability agents. Instead, biases are significant elements of human decision-making at the highest levels of organizations.

An important question for future research is how to limit, in each CEO career phase, the adverse effects of managerial biases. Potential approaches include refining selection mechanisms, designing and implementing corporate repairs, and reshaping corporate governance to account not only for incentive misalignments but also for biased decision-making.
