Using data of publicly traded firms in the U.S. from 1995 to 2017, we show that firms with optimistic CEOs have higher employment growth and exhibit less pronounced employment sensitivity to declining sales than firms with non-optimistic CEOs do. We also find that the impact of optimistic CEOs on employment decisions is larger in finan cially constrained firms. We deal with potential endogeneity issues with the entropy balancing method, propensity score matching and two-stage least squares regression. Our find ings have important implications for the design and imple mentation of Human Resource Management policieenCEO optimismemployment decisionsfinancial constraintssales growthArticle
