Equity Prices the Opportunity, Debt Prices the Risk: Generative AI and Corporate Credit Spreads
With P. Gandhi, J. Lu, A. Plazzi, and J. Wei. [SSRN]
Corporate bond spreads widen by roughly eight basis points per standard deviation of workforce exposure to generative AI after the release of ChatGPT, while equity valuations rise. A structural credit model with parameter uncertainty reconciles the opposing responses, which concentrate in credit-fragile firms.

Do Measures of Bank Diversification “Measure Up”?
With P. Gandhi and D. Palia. [SSRN]
Standard measures of bank business line diversification do not capture the diversification effect. We propose a correlation-adjusted entropy measure, validate it against the Dodd-Frank and Economic Growth Acts, and find that diversified banks are more profitable and carry lower bankruptcy, tail, and systemic risk.

Awaiting the Prompt? Generative AI Uncertainty and Firm-Level Investment
With P. Gandhi, S. Kedia, J. Lu, and J. Wei. [SSRN]
Firms with greater workforce exposure to generative AI cut investment after the release of ChatGPT, by 0.57 percentage points of lagged assets per standard deviation of exposure. The decline concentrates in physical capital and is smaller where assets are redeployable, consistent with a real-options mechanism: uncertainty raises the value of waiting under irreversibility.
