Why do so few women become CEOs? To understand this glass ceiling, we estimate a dynamic model of the CEO gender decision, which contains perceived gender productivity differences, search costs reflecting limited female labor supply, and employer disutility from discrimination. The key factor is the shortage of suitable female candidates, as boards prefer hiring women, and productivity differences between genders are minimal. We find no evidence of a glass cliff in which women become CEOs just as firms are failing. While better governance is associated with women becoming CEOs, the importance of limited female labor supply is unrelated to governance.

We examine how relative performance evaluation (RPE) affects industry competition—a question relevant for corporate boards interested in incentivizing executives. Using U.S. airline data, we estimate a dynamic game of competition between heterogeneous firms in an oligopolistic market, with managers incentivized by RPE contracts. While RPE can induce a firm to compete more intensely by smoothing compensation, it also amplifies a firm’s cost efficiency relative to its peers and can weaken competition from inefficient firms. The first effect dominates in small markets and the second in median-sized markets. RPE has little effect in large, highly profitable markets.

This paper examines whether corporate social responsibility (CSR) aligns with shareholder interests or stems from agency conflicts. To explore this, we utilize the staggered adoption of state-level Corporate Opportunity Waiver (COW) laws, which potentially weaken the fiduciary duty of loyalty among directors and officers, thereby exacerbating agency conflicts. Through a difference-in-differences analysis, we find that CSR activities significantly decrease following the enactment of COW laws. This decline is more pronounced in firms with weaker corporate governance, greater external opportunities for directors and officers, less incentivized CEOs, and those operating in less competitive industries. Additionally, our results show that the positive effect of CSR on financial performance is diminished by the adoption of COW laws. These findings support the value-enhancing perspective of CSR and highlight the importance of fiduciary duty of loyalty in promoting CSR.
