Another perspective on Milberg Weiss: Perino responds
[The following is from Mike Perino, author of the paper I commented on in yesterday's post].
I would like to thank Larry and Bruce for taking the time to comment so thoroughly on my paper. Their comments fall into two broad categories. First, they argue “even if the evidence shows what it purports to show, this does not establish that the class members were harmed.” (emphasis in original). Second, they question whether there are specification errors in the regressions that may undermine the results. I’ll tackle each of these critiques in turn.
Larry and Bruce’s first comment is implicitly premised on this question: If one could add up all the costs and all the benefits of a system that allowed class action attorneys to share revenues with the clients who were willing to serve as lead plaintiffs, would absent class members (and presumably the markets as a whole) be better or worse off than under our current system which bans such payments? In essence, they argue that investors might be better off because this kind of fee sharing might motivate the lawyers to file higher quality complaints.
I agree this is an interesting question and I am willing to concede for the sake of argument that such a system might create the benefit they suggest. But, I have to disagree with Larry and Bruce when they say that this is a question that I “missed.” The reality is that this is simply not the question that my paper sought to address. The paper never attempted to tally all of the costs and benefits of allowing revenue sharing between lawyers and their clients. Indeed, it is difficult to image how one might even try to assess this question empirically. How exactly do we measure the benefit of higher quality complaints? For that matter, what metric do we use to measure complaint quality?
Although this is not the paper I sought to write, it is worth noting that if one were to undertake such a project one would have to consider several costs that Larry and Bruce “miss.” For example, part of the standard critique of securities class actions is that they might lead lawyers to bring not only strong cases of fraud, but also marginal or non-meritorious ones purely for their settlement value. Paying plaintiffs might lead to more suits of this variety as well. And, if we really wanted to do the analysis correctly, we would want to evaluate not only the costs and benefits of the system that Larry and Bruce propose, but also the costs and benefits of other systems that seek to encourage lawyers to file higher quality complaints (including our current system that imposes a heightened pleading standard in this type of case).
The difficulties associated with attempting such an analysis are obvious and I don’t want to dwell on them here because, again, this is not what my paper is about. Rather than attempting to grapple with these likely incalculable costs and benefits, my goal for the paper was much more modest and involved a far more tractable empirical question. I sought to assess the government and Milberg’s competing claims concerning the propriety of the prosecution. The government claimed that its prosecution was justified because kickbacks were more than a mere ethical lapse. It argued that they created a conflict of interest between the representative plaintiff and absent class members that led to excessive fees. Milberg and Bill Lerach, by contrast, say that kickbacks may have spurred representative plaintiffs to hold out for higher settlements and that courts would have reduced any fees that were too high. The only claim I make in the paper is that the empirical evidence I compile is more consistent with the government’s position than with Milberg’s. The paper shows that, all else equal, there is no statistically significant correlation between recoveries and either the indictment cases or cases with repeat plaintiffs.
So the available data do not support Milberg’s argument that kickbacks created incentives that actually led plaintiffs to hold out for higher settlement amounts. By contrast, means comparisons show that: (1) average fee requests and awards in the indictment cases were significantly higher than those in the non-indictment cases; (2) Milberg Weiss’ average fee requests and awards were significantly larger than those of other plaintiffs’ law firms; and (3) within the subset of Milberg Weiss cases, the firm’s average fee requests and awards were higher in the indictment cases than in other cases. The regressions show the impact of the Indictment variable (or in alternate specifications the presence of repeat plaintiffs) is not uniform across cases but instead varies with the size of the settlement. As settlements grew larger, the fee requests and awards in the indictment cases grew at a faster rate than those in the non-indictment cases. All of this is consistent with the government’s contention that kickbacks led to excessive fees.
So, while Larry and Bruce raise an important normative question about whether we should allow this kind of revenue sharing, that question does not alter the core conclusions of this paper, a point that they acknowledge (“The apparent reason why Perino does not focus on this theory is simply that the defendants didn’t rely on it.”). And, although they seem to suggest otherwise in their critique, I never take the normative position that revenue sharing should be banned outright. Quite the opposite is true—in the theoretical section of my paper (pages 21-23) I point out that under certain conditions (specifically where the plaintiff owns a sufficiently large portion of the underlying claim) revenue sharing might indeed encourage plaintiffs to hold out for higher settlements. I have publicly taken the position that we should require disclosure of pay-to-play payments made to the campaigns of state officials that control public pension fund participation in class actions rather than enacting any outright ban. And, I have questioned whether the PSLRA’s ban on incentive payments should be reconsidered if we truly want to encourage institutional investors to take on the lead plaintiff role. See Markets and Monitors: The Impact of Competition and Experience on Attorneys’ Fees in Securities Class Actions.
This brings me to one additional point. Larry and Bruce argue that I look “at only one side of the theoretical story, whether the fees motivated better monitoring by named plaintiffs.” Larry and Bruce then argue that “this story is not particularly interesting because … even non-bribed plaintiffs would have little incentive or ability to affect class action outcomes.” In support of this claim they cite Eisenberg and Miller’s paper on attorneys’ fees, which finds no significant correlation between fees and passage of the PSLRA. But, of course, if one wanted to examine the impact of better monitoring, relying solely on whether the case was filed before or after passage of the act would be a poor proxy because post-PSLRA cases contain a mix of traditional small-stakes plaintiffs and non-traditional institutional investors. In another paper (which their critique does not cite), I show that, all else equal, cases with public pension lead plaintiffs have, among other things, significantly lower fee requests and fee awards than cases involving other types of plaintiffs. See Institutional Activism through Litigation: An Empirical Assessment of Public Pension Fund Participation in Securities Class Actions. So I disagree with Larry and Bruce with respect to the potential benefits of enhanced monitoring.
That brings me to their comments on the model specifications. The thrust of this critique is that I fail to adequately account for the probability that fee requests and fee awards will be below one-third of the settlement as settlement size increases. They recognize that as a robustness check I truncated the dataset to omit fee requests in excess of $100 million, but they argue that this is inadequate for a variety of reasons. Instead, they suggest, among other things, that I should truncate settlements in excess of $100 million. It turns out that I performed just such an analysis when I was writing this paper, but did not discuss the results because they were similar to the results discussed in the paper.
Consider, for example, the regressions for fee awards. When fee requests above $100 million are omitted (this is Model 3 in Table 6), the coefficient for the interaction term is 0.059 (p = 0.027). When, as Larry and Bruce propose, settlements greater than $100 million are omitted, the correlation is actually somewhat stronger (coefficient = 0.080; p = 0.001). The same is true for fee requests. So, adopting this methodological suggestion does not alter the empirical results, but I’ll make sure that any future versions of the paper disclose this finding as well.
Quick response: Thanks for Mike for this thoughtful rejoinder. I will only respond here that, again assuming the validity of Mike's results, there remains a question in light of Bruce and my theoretical approach whether class members are harmed by these payments. The Milberg defendants deserve their punishment because the kickbacks were wrong under current law. The question whether such payments should be wrong deserves more attention in the overall policy debate on class actions.
