Rank and file employees execute firms’ daily operating activities, but prior research rarely examines their importance due to a lack of employee information. In this article, we use a novel data set—company reviews by rank and file employees—to provide evidence on the impact of employee satisfaction on a firm’s cost of equity capital. We find that firms with higher employee satisfaction have a lower cost of equity. Our results are robust to a variety of endogeneity tests and model specifications. We also find that the effect of employee satisfaction is more pronounced for firms with higher risk, greater financial constraints, and higher labor intensity or product market competition where labor is more critical to firm success. Further analysis shows that the negative association between employee satisfaction and the cost of equity is primarily grounded in reviews from current rather than former employees. Finally, we document that firms with high employee satisfaction experience lower systematic and idiosyncratic risk. Overall, our article presents novel evidence on the capital market benefits of higher employee satisfaction, particularly with regard to financing cost reduction.
