After medical marijuana legalization (MML) by U.S. states, firms’ cost of equity (COE) decreases, especially for those with more growth opportunities, higher productivity, or a more skilled workforce. This policy change also reduces firm risk and leads to an increase in labor supply through increased labor force participation, employment, hours worked, and net migration. Further, home prices rise after MML, reflecting increased local housing demand due to a growing supply of workers. These findings align with theoretical models that link asset prices to labor markets and suggest that MML can lower firms’ COE by mitigating labor search frictions.

We introduce the implied value premium ( IVP ), the difference between the implied costs of capital of value and growth stocks, to predict time variation in the ex post value premium. During 1977–2023, IVP is the strongest predictor of the ex post value premium. It also predicts the investment premium, consistent with the Investment CAPM. However, IVP ’s ability to predict the difference in cumulative abnormal returns around quarterly earnings announcements of value and growth stocks suggests that mispricing may also play a role. Overall, our results suggest that recent value underperformance reflects cyclical variation rather than a permanent shift.

Using the near universe of online job postings from 2007 to 2021, we construct a firm-level metric of labor market power. We find that firms with higher labor market power tend to have higher financial leverage. Our findings are not driven by product market competition or correlated labor market characteristics. The evidence is less pronounced among firms hiring in occupations with high labor mobility and skill transferability. To establish causality, we exploit the establishment of Amazon HQ2 in Crystal City as a shock to the labor market power of local firms and show consistent findings with our baseline results.
