The Effects of Hedge Fund Activism

Author: Andrew Baker

In this paper I explore the relationship between the rise of hedge fund activism and firm outcomes, using a study design that explicitly takes into account how activists pick their targets. Contrary to much prior work, I find no evidence that activism is associated with increased firm operating performance or significant long-term returns once comparing to firms based on their similarity to the targets. However, activism does increase firm payouts to shareholders and decreases investment, consistent with the argument of many critics of activism. I also find that firm-level employment declines significantly following a targeting event, and that the subset of firms that experience an increase in operating performance also engage in higher levels of tax avoidance. The deregulation of proxy access rules, wholesale de-staggering of corporate boards, and the rise in importance of proxy advisory firms who frequently recommend voting for activist proposals have made firms more susceptible to aggressive activism over the past three decades. The results in this paper, coupled with the rhetorical shift in focus from short-term profits to sustainable growth by large institutional investors, suggest a re-framing of the public debate over the benefits of shareholder activism.
