Automation and the displacement of labor by capital: Asset pricing theory and empirical evidence

Journal of Financial Economics 2023 147(2), 271-296 open access
I examine the asset pricing implications of technological innovations that allow capital to displace labor: automation. I develop a theory in which firms with displaceable labor are negatively exposed to such technology shocks. In the model, firms optimally adopt technology to gain competitive advantage but in equilibrium competition erodes profits and decreases firm value. Empirically, I find that firms with high share of displaceable labor have negative exposure to technology shocks. A long-short portfolio sorted on this variable mimics macroeconomic measures of technology shocks. Negatively exposed firms earn a 4% annual return premium consistent with displacement risk from technological progress.

How valuable is corporate adaptation to crisis? Estimates from Covid-19 work-from-home announcements

Journal of Financial Economics 2025 174, 104168 open access
This article investigates predictors and benefits of corporate adaptation to crisis, adding a new dimension to studies of flexibility and resilience based on ex ante characteristics. We produce a unique sample of work-from-home announcements scraped from company websites during Covid-19. The announcers’ valuations increased by 3%–5% and risk declined versus matches, consistent with real-options theory under asymmetric information. We estimate characteristics, including subtle textual topics from 10-Ks, that predicted adaptation, show faster price response following Bloomberg coverage, and real advantages in subsequent operating performance. Corporate adaptation to crisis adds value and reduces risk, beyond information in firm characteristics.
