“Martin Lipton is a founding partner of Wachtell, Lipton, Rosen & Katz, and this post is based on a Wachtell Lipton memorandum. The post puts forward criticism of an empirical study by Lucian Bebchuk, Alon Brav, and Wei Jiang on the long-term effects of hedge fund activism; this study is available here, and its results are summarized in a Forum post and in a Wall Street Journal op-ed article. As did an earlier post by Mr. Lipton available here, this post relies on the work of Yvan Allaire and François Dauphin that is available here. A reply by Professors Bebchuk, Brav, and Jiang to this earlier memo and to the Allaire-Dauphin work is available here. Additional posts discussing the Bebchuk-Brav-Jiang study, including additional critiques by Wachtell Lipton and responses to them by Professors Bebchuk, Brav, and Jiang, are available on the Forum here.
