I am writing a monthly column entitled "Experts Corner" in a terrific new publication, Class Actions Attorney Fee Digest. My first column , co-authored with my friend Alan Hirsch, appeared in February. It discusses In re Stock Exchanges Options Trading Antitrust Litigation, 2006 U.S. Dist. LEXIS 87825 (S.D.N.Y. Dec. 4, 2006), a case in which the district judge chose to use a lodestar rather than percentage fee based on the fact that the plaintiffs' were only partially successful. Alan and I are critical of this choice, arguing that the percentage method would have been more efficient and would have been well-tailored to capture the partial success since it would have been only a percentage of the fund that the plaintiffs actually recovered.
