We use the 2003 NYSE and NASDAQ listing rules for board and committee independence as a quasinatural experiment to examine the causal relations between board structure and CEO monitoring. Noncompliant firms forced to raise board independence or adopt a fully independent nominating committee significantly increased their forced CEO turnover sensitivity to performance relative to compliant firms. Nominating committee independence is important even when firms had an independent board, and the effect is stronger when the CEO is on the committee. We conclude that greater board independence and full independence of nominating committees lead to more rigorous CEO monitoring and discipline.

Using the staggered adoption of Universal Demand (UD) laws at the state level that increased the hurdle of shareholder derivative suits as a shock, we find that reduced litigation threat increases workplace injury rates. The effect is more pronounced for treated firms facing higher litigation risk, less product market competition, in low union coverage industries, and with Employee Stock Ownership Plans (ESOPs). Treated firms with high ownership by “dedicated” or local institutional investors are less affected as these investors can monitor safety through voice and exit. Safety inputs fall in treated firms following the adoption of UD laws. Overall, the findings suggest that shareholder litigation threat plays a critical role in workplace safety.

We study changes in independent director behavior and labor-market outcomes after the experience of a forced Chief Executive Officer (CEO) turnover. We find that independent directors are more willing to fire CEOs of underperforming firms, hire outside CEOs after a firing, and encourage better board-meeting attendance by fellow directors. We also find that the shareholders of poorly performing firms react positively when experienced directors join the board. It does come with a small cost for directors, in terms of additional directorships, although the cost is not as great as that for directors who do not fire the CEO of a poorly performing firm.
