    Recent advances in research on hedge fund activism: Value creation and identification
    Brav, Alon; Jiang, Wei; Kim, Hyunseob (Annual Review of Financial Economics, 2015-12)
    Hedge fund activism has emerged as a major force of corporate governance since the 2000s. By the mid-2000s, there were between 150–200 activist hedge funds in action each year, advocating for changes in 200–300 publicly listed companies in the U.S. In this paper, we review the evolution and major characteristics of hedge fund activism, as well as the short- and long-term impact of such activities on the performance and governance of the targeted companies. Though most of the analyses are based on a comprehensive sample of over 2,000 activism events in the U.S. from 1994 to 2011, hand-collected by the authors from regulatory filings and news searches, this paper covers all major studies on the topic, including those on non-U.S. markets.

    Hedge Fund Activism: A Review
    Brav, Alon; Jiang, Wei; Kim, Hyunseob (Foundations and Trends in Finance, 2009-01-01)
    This monograph reviews shareholder activism by hedge funds. We first describe the nature and characteristics of hedge fund activism, including the objectives, tactics, and choices of target companies. We then analyze possible value creation brought about by activist hedge funds, both for shareholders in the target companies and for investors in the hedge funds. The evidence generally supports the view that hedge fund activism creates value for shareholders by effectively influencing the governance, capital structure decisions, and operating performance of target firms.
