The Reduced Form Of Litigation Models And The Plaintiff's Win Rate, Jonah B. Gelbach Sep 2016

The Reduced Form Of Litigation Models And The Plaintiff's Win Rate, Jonah B. Gelbach

All Faculty Scholarship

In this paper I introduce what I call the reduced form approach to studying the plaintiff's win rate in litigation selection models. A reduced form comprises a joint distribution of plaintiff's and defendant's beliefs concerning the probability that the plaintiff would win in the event a dispute were litigated; a conditional win rate function that tells us the actual probability of a plaintiff win in the event of litigation, given the parties' subjective beliefs; and a litigation rule that provides the probability that a case will be litigated given the two parties' beliefs. I show how models with very different-looking …


The Law And Economics Of Proportionality In Discovery, Jonah B. Gelbach, Bruce H. Kobayashi Jan 2016

The Law And Economics Of Proportionality In Discovery, Jonah B. Gelbach, Bruce H. Kobayashi

All Faculty Scholarship

This paper analyzes the proportionality standard in discovery. Many believe the Advisory Committee's renewed emphasis on this standard has the potential to infuse litigation practice with considerably more attention to questions related to the costs and benefits of discovery. We discuss the history and rationale of proportionality's inclusion in Rule 26, adopting an analytical framework that focuses on how costs and benefits can diverge in litigation generally, and discovery in particular. Finally, we use this framework to understand the mechanics and challenges involved in deploying the six factors included in the proportionality standard. Throughout, we emphasize that the proportionality standard …


Can We Learn Anything About Pleading Changes From Existing Data?, Jonah B. Gelbach Jan 2015

Can We Learn Anything About Pleading Changes From Existing Data?, Jonah B. Gelbach

All Faculty Scholarship

In light of the gateway role that the pleading standard can play in our civil litigation system, measuring the empirical effects of pleading policy changes embodied in the Supreme Court's controversial Twombly and Iqbal cases is important. In my earlier paper, Locking the Doors to Discovery, I argued that in doing so, special care is required in formulating the object of empirical study. Taking party behavior seriously, as Locking the Doors does, leads to empirical results suggesting that Twombly and Iqbal have had substantial effects among cases that face Rule 12(b)(6) motions post-Iqbal. This paper responds to …

The Relational Contingency Of Rights, Gideon Parchomovsky, Alex Stein Feb 2012

The Relational Contingency Of Rights, Gideon Parchomovsky, Alex Stein

All Faculty Scholarship

In this Article, we demonstrate, contrary to conventional wisdom, that all rights are relationally contingent. Our main thesis is that rights afford their holders meaningful protection only against challengers who face higher litigation costs than the rightholder. Contrariwise, challengers who can litigate more cheaply than a rightholder can force the rightholder to forfeit the right and thereby render the right ineffective. Consequently, in the real world, rights avail only against certain challengers but not others. This result is robust and pervasive. Furthermore, it obtains irrespectively of how rights and other legal entitlements are defined by the legislator or construed by …


Locking The Doors To Discovery? Assessing The Effects Of Twombly And Iqbal On Access To Discovery, Jonah B. Gelbach Jan 2012

Locking The Doors To Discovery? Assessing The Effects Of Twombly And Iqbal On Access To Discovery, Jonah B. Gelbach

All Faculty Scholarship

Many observers believe the Supreme Court’s Twombly and Iqbal opinions have curtailed access to civil justice. But previous empirical studies looking only at Rule 12(b)(6) grant rates have failed to capture the full effect of these cases because they have not accounted for party selection—changes in party behavior that can be expected following changes in pleading standards. In this Note, I show how party selection can be expected to undermine the empirical usefulness of simple grant-rate comparisons. I then use a conceptual model of party behavior that allows me to derive an adjusted measure of Twombly/Iqbal’s impact and show …


Vultures Or Vanguards?: The Role Of Litigation In Sovereign Debt Restructuring, Jill E. Fisch, Caroline M. Gentile Jan 2004

Vultures Or Vanguards?: The Role Of Litigation In Sovereign Debt Restructuring, Jill E. Fisch, Caroline M. Gentile

All Faculty Scholarship

The market for sovereign debt differs from the market for corporate debt in several important ways including the risk of opportunistic default by sovereign debtors, the importance of political pressures, and the presence of international development organizations. Moreover, countries are subject to neither liquidation nor standardized processes of debt reorganization. Instead, negotiations between a sovereign debtor and its creditors lead to a voluntary restructuring of the sovereign's debt. One of the greatest difficulties in restructuring claims against sovereign debtors is balancing the interests of the majority of the creditors with those of minority creditors. Holdout creditors serve as a check …


“Black People’S Money”: The Impact Of Law, Economics, And Culture In The Context Of Race On Damage Recoveries, Regina Austin Jul 2003

“Black People’S Money”: The Impact Of Law, Economics, And Culture In The Context Of Race On Damage Recoveries, Regina Austin

All Faculty Scholarship

“’Black People’s Money’: The Impact of Law, Economics, and Culture in the Context of Race on Damage Recoveries” is one of a series of articles by the author dealing with black economic marginalization; prior work considered such topics as shopping and selling as forms of deviance, street vending, restraints on leisure, and the importance of informality in loan transactions. This article deals with the linkage between the social significance of black people’s money and its material value. It analyzes the construction of “black money,” its association with cash, and the taboos and cultural practices that assure that black money will …

Lawyers On The Auction Block: Evaluation And Selection Of Class Counsel By Auction, Jill E. Fisch Jan 2002

Lawyers On The Auction Block: Evaluation And Selection Of Class Counsel By Auction, Jill E. Fisch

All Faculty Scholarship

The lead counsel auction has attracted increasing attention. Auction advocates argue that auctions introduce competitive market forces that improve the selection and compensation of class counsel. The benefits of the auction, the;' claim, include lower legal fees and better representation. Careful scrutiny reveals that auction advocates have overlooked substantial methodological problems with the design and implementation of the lead counsel auction. Even if these problems were overcome, the auction procedure is flawed: Auctions are poor tools for selecting firms based on multiple criteria, compromise the judicial role, and are unlikely to produce reasonable fee awards. Although the existing record is …

Incentives To Settle Under Joint And Several Liability: An Empirical Analysis Of Superfund Litigation, Howard F. Chang, Hilary Sigman Jan 2000

Incentives To Settle Under Joint And Several Liability: An Empirical Analysis Of Superfund Litigation, Howard F. Chang, Hilary Sigman

All Faculty Scholarship

Congress may soon restrict joint and several liability for cleanup of contaminated sites under Superfund. We explore whether this change would discourage settlements and is therefore likely to increase the program 's already high litigation costs per site. Recent theoretical research by Kornhauser and Revesz finds that joint and several liability may either encourage or discourage settlement, depending on the correlation of outcomes at trial across defendants. We extend their two-defendant model to a richer framework with N defendants. This extension allows us to test the theoretical model empirically using data on Superfund litigation. We find that joint and several …


The Scope Of Private Securities Litigation: In Search Of Liability Standards For Secondary Defendants, Jill E. Fisch Jan 1999

The Scope Of Private Securities Litigation: In Search Of Liability Standards For Secondary Defendants, Jill E. Fisch

All Faculty Scholarship

Recent federal court decisions have struggled to apply the Supreme Court's decision in Central Bank v. First Interstate to determine when outside professionals should be held liable as primary violators under section IO(b) of the Securities Exchange Act. In keeping with the Court's current interpretive methodology, Central Bank and its progeny employ a textualist approach. In this Article, Professor Fisch argues that literal textualism is an inappropriate approach for interpreting the federal securities laws generally and misguided in light of legislative developments post-dating the Central Bank decision. Instead, Professor Fisch advocates an approach that weighs Congress 's recent endorsement of …

An Analysis Of Fee Shifting Based On The Margin Of Victory: On Frivolous Suints, Meritorious Suits, And The Role Of Rule 11, Howard F. Chang, Lucian A. Bebchuk Jan 1996

An Analysis Of Fee Shifting Based On The Margin Of Victory: On Frivolous Suints, Meritorious Suits, And The Role Of Rule 11, Howard F. Chang, Lucian A. Bebchuk

All Faculty Scholarship

When plaintiffs cannot predict the outcome of litigation with certainty, neither the American rule (each litigant bears its own litigation expenses) nor the British rule (the losing litigant pays the attorneys' fees of the winning litigant) would induce optimal decisions to bring suit. Plaintiffs may bring frivolous suits when litigation costs are small relative to the amount at stake; plaintiffs may not bring meritorious suits when litigation costs are large relative to this amount. More general fee-shifting rules are based not only on the identity of the winning party but also on how strong the court perceives the case to …
