Labor input is an important factor in a firm's production and affects stock return. We use an optimization model to explore the stock return-labor hiring relation with the effects of employment frictions and labor supply. Our model illustrates that labor hiring is negatively related to the expected stock return from the discount rate channel; the negative return-hiring relation becomes steeper when the firm's employment frictions are higher; positive labor supply shock leads to a flatter return-hiring relation. Using Chinese-listed firm data, we provide evidence for the existence of the return-hiring relation and the impact of employment frictions and labor supply confirming the theoretical predictions.
