We study the impact of labor market frictions on asset prices. In the cross section of US firms, a 10 percentage point increase in the firm's hiring rate is associated with a 1.5 percentage point decrease in the firm's annual risk premium. We propose an investment-based model with stochastic labor adjustment costs to explain this finding. Firms with high hiring rates are expanding firms that incur high adjustment costs. If the economy experiences a shock that lowers adjustment costs, these firms benefit the most. The corresponding increase in firm value operates as a hedge against these shocks, explaining the lower risk premium of these firms in equilibrium.
