We examine how an investor collective action organization (ICAO) enhances activism by institutional investors. The ICAO initiated a new form of engagement—private meetings with independent directors to discuss governance proposals. Compared with a single investor acting alone, the ICAO has stronger incentives to engage in activism. Its dollar holdings and voting power are six times larger and predict direct access to the board and the firms it engages. Firms engaged by the ICAO are at least 58% more likely than non-engaged firms to adopt the ICAO’s governance proposals that include adoption of majority voting, say-on-pay, and specific compensation policies. Engaged firms also increase CEO incentive pay. An event study around the announcement of the ICAO’s formation shows a positive impact on value that increases in both dollar holdings and voting power. We conclude that institutional investors improve governance outcomes through collective action.

This paper assesses whether shareholders drive the environmental and social (E&S) performance of firms worldwide. Across 41 countries, institutional ownership is positively associated with E&S performance with additional tests suggesting this relation is causal. Institutions are motivated by both financial and social returns. Investors increase firms’ E&S performance following shocks that reveal financial benefits to E&S improvements. In cross section, investors increase firms’ E&S performance when they come from countries with a strong community belief in the importance of E&S issues, but not otherwise. As such, these institutional investors transplant their social norms regarding E&S issues around the world.
