Shareholder litigation and toxic releases

We examine the environmental impact of the staggered adoption of universal demand laws by 23 U.S. states between 1989 and 2005. Universal demand laws impede derivative lawsuits and thus undermine shareholder oversight of corporate environmental performance. We find that weakened litigation rights for shareholders are positively associated with the release of toxic chemicals by firms. The effect is stronger for firms with weak governance, and environmental mismanagement by firms after the passage of the laws lead to poorer financial performance. Overall, our findings imply that derivative lawsuits by shareholders are not frivolous, as is often asserted. Rather, they act as an effective mechanism of corporate governance.
