The Cross-Section of Labor Leverage and Equity Returns
The relative size and inflexibility of labor expenses lead to a form of operating leverage, which we call labor leverage. We derive a set of conditions for the existence of labor leverage even when labor markets are frictionless. Our model provides theoretical support for the use of firm-level labor share as a measure of labor leverage. Using Compustat/CRSP and confidential Census data, we provide evidence for the existence and for the economic significance of labor leverage: high labor share firms have operating profits that are more sensitive to economic shocks and have higher expected returns.Citation:
