The Stock Market Reaction To Class Action Filings Post Pslra, Mark S. Klock
The Stock Market Reaction To Class Action Filings Post Pslra, Mark S. Klock
Mark S Klock
Using a substantially larger sample than has been used before, and a sample that includes the Great Financial Crisis and its ensuing recession, I investigate the stock market reaction to securities class action filings following the enactment of the Private Securities Litigation Reform Act through the first quarter of 2012. I find that on average, even after adjusting for market downturns, there is a statistically significant negative abnormal return at the time of filing. There is also a statistically significant negative abnormal return during the weeks preceding the filing indicating that the market partially, but not fully, anticipates these filings. …
It's Not All Statistics: Demystifying Empirical Research, Sarah J. Morath
It's Not All Statistics: Demystifying Empirical Research, Sarah J. Morath
Sarah J Morath
Although Oliver Wendell Holmes was touting the merits of empirical research over one hundred years ago, only recently have legal academics created a journal and conference dedicated to empirical legal studies. Interestingly, topics of interest to legal writing professors have been a source for empirical research well before the emergence these specialized journals and conferences. For example, empirical research comparing the use of legal prose to plain English in appellate briefs was taking place over 25 years ago. In 1996, the second volume of The Journal of Legal Writing Institute included an empirical study evaluating which professors’ comments students found …
What's Good In Theory May Be Flawed In Practice: Potential Legal Consequences Of Poor Implementation Of A Theoretical Sample, Melanie S. Williams, A. Lynn Phillips, G. Michael Phillips
What's Good In Theory May Be Flawed In Practice: Potential Legal Consequences Of Poor Implementation Of A Theoretical Sample, Melanie S. Williams, A. Lynn Phillips, G. Michael Phillips
Melanie S. Williams
The article discusses the problem of the use in litigation of statistical sampling. Sample-based research is increasingly used in cases as diverse as products liability, antitrust, intellectual property, and criminal law, among others. Sample-based research provides objective evidence upon which decisions, damages and liability may rest. Despite its importance, however, statistical evidence is often misused and misunderstood by attorneys who may be unfamiliar with the underlying form of analysis. The paper explores common errors when using litigative samples, comments upon best practices for the use in law of sample-based research, and demonstrates the importance of sound statistical sampling and data …
Gender And Partner Compensation At America's Largest Firms, Marina Angel
Gender And Partner Compensation At America's Largest Firms, Marina Angel
Marina Angel
Abstract
This study compiled the largest research sample on the gender gap in compensation at the 200 largest law firms by combining two large databases to examine the compensation disparities between men and women partners. The analysis elucidates the question of whether the difference is because women are less productive than men partners or because they are women. The Am Law 100 and 200 studies include gross revenue, profits, number of equity and non-equity partners, and the total number of lawyers at each firm. The Vault/MCCA Law Firm Diversity Programs study (Vault/MCCA) includes the gender ratios at each Am Law …

How A Changing Nation Is Fueling The Rise Of Trade Secret Litigation, David S. Almeling
How A Changing Nation Is Fueling The Rise Of Trade Secret Litigation, David S. Almeling
David S. Almeling
Reports of pilfered trade secrets have grown increasingly common, and as recent studies demonstrate, trade secret litigation is on the rise. A 2010 study of the federal courts shows that trade secret litigation has grown exponentially while litigation in general has decreased. And a 2011 study of state courts shows that trade secret litigation is increasing at a faster rate than the rate of litigation in general. This essay asks: Why? Why is trade secret litigation more prevalent than ever? This essay posits — for the first time — explanations for the fact that trade secrets are increasingly important to …
Statistical Evidence On The Gender Gap In Law Firm Partner Compensation, Marina Angel, Eun Young Whang, Rajiv Banker, Joseph F. Lopez
Statistical Evidence On The Gender Gap In Law Firm Partner Compensation, Marina Angel, Eun Young Whang, Rajiv Banker, Joseph F. Lopez
Marina Angel
Our study compiled the largest research sample on the gender gap in compensation at the 200 largest law firms by combining two large databases to examine why women partners are compensated less: because they are less productive than men partners or because they are women. The AmLaw 100 and 200 studies include gross revenue, profits, number of equity and non-equity partners, and the total number of lawyers at each firm. The Vault/MCCA Law Firm Diversity Programs study (Vault/MCCA) includes the gender ratios at each AmLaw 200 firm. Our study covers the years 2002 to 2007.
The ratio of women equity …
Lessons From Single-Company Event Studies: The Importance Of Controlling For Company-Specific Events, Scott D. Hakala
Lessons From Single-Company Event Studies: The Importance Of Controlling For Company-Specific Events, Scott D. Hakala
Scott D Hakala
Single-company event studies are commonly employed in applied practice, such as in analyzing market efficiency, reliance, and damages in securities litigation. However, the presence of significant company-specific events among the observations used to estimate the market model results in significantly biased, overstated standard errors (a well-known omitted variables problem) and less reliable coefficient estimates in such studies. This is a frequently over-looked or neglected issue that renders the statistical inferences in single-company event studies employing using more traditional event study techniques biased and often unreliable. This paper demonstrates through simulation and actual examples that, even allowing for errors in implementation, …

The purpose of the present paper is to contribute to the empirical literature on country interlocks by illustrating and analysing the interlocking directorships in the first 40 Italian, French and British Blue Chips as of December 2007 (Italy)/March 2008 (France and uk). The theoretical literature identify two possible explanations for interlocking directorships, on the one hand the collusion among players in the same market or in general among enterprises that have business relations among themselves; on the other hand the interest for enterprises to have on their boards bankers, suppliers, and clients so as to reduce information asymmetries. Our findings …

Empirical legal scholars have traditionally modeled judicial opinion writing by assuming that judges act rationally, seeking to maximize their influence by writing opinions in politically important cases. Support for this hypothesis has reviewed published opinions, finding that civil rights and other “hot” topics are more to be discussed than other issues. This orthodoxy comforts consumers of legal opinions, because it suggests that opinions are largely representative of judicial work. The orthodoxy is substantively and methodologically flawed. This paper starts by assuming that judges are generally risk averse with respect to reversal, and that they provide opinions when they believe that …

Lies, Damn Lies And Statistics: Developing A Clearer Assessment, Rob M. Frieden
Rob Frieden
Depending on the source one can conclude that United States consumers enjoy access to a robustly competitive and nearly ubiquitous marketplace for inexpensive broadband Internet access, or they suffer the consequences of a tightly concentrated industry offering inferior service at high rates. On one hand, the Federal Communications Commission (“FCC”), the National Telecommunications and Information Administration (“NTIA”) and some sponsored researchers offer a quite sanguine outlook, possibly influenced by their appreciation for the political and public relations dividends in compiling positive results. On the other hand, other statistical compilations and interpretations show the U.S. behind in terms of market penetration …
Turning A Blind Eye To Misleading Scientific Testimony: Failure Of Procedural Safeguards In A Capital Trial, William C. Thompson
Turning A Blind Eye To Misleading Scientific Testimony: Failure Of Procedural Safeguards In A Capital Trial, William C. Thompson
William C Thompson
In September 1999, Robin Lovitt was convicted and sentenced to death for the murder of a pool hall manager in Arlington, Virginia. The DNA evidence that was a key part of the government’s case was presented in a misleading and unfair manner. In this case study, we first examine the way in which DNA evidence was misused. We then discuss the failure of the legal system at all levels to recognize and remedy this problem. Our goal is to explain how a system that supposedly leaves no stone unturned in capital trials managed to miss or ignore a crucial problem …
Correlation Versus Causality: Further Thoughts On The Law Review/Law School Liaison, Ronen Perry
Correlation Versus Causality: Further Thoughts On The Law Review/Law School Liaison, Ronen Perry
Ronen Perry
This Essay is the third in a series of articles discussing the relative value of American law reviews, and a response to Professor Alfred Brophy's elaboration of my initial study of the high mathematical correlation between law review quality, as manifested in citation-based measures, and law school reputation. Given my prior interest in the relative value of American law reviews, I have used the abovementioned correlation as a means to explain some of the variance in quality among law reviews. Brophy's empirical findings overlap mine, yet the extent of his analysis, as well as his interpretation and utilization of the …
The Relative Value Of American Law Reviews: Refinement And Implementation, Ronen Perry
The Relative Value Of American Law Reviews: Refinement And Implementation, Ronen Perry
Ronen Perry
This Article complements a recently published paper in which I discussed the theoretical and methodological aspects of law review rankings. The purpose of this Article is twofold: refinement of the theoretical framework, and implementation. It proposes, defends, and implements a complex ranking method for general-interest student-edited law reviews, based on a judicious weighting of normalized citation frequency and normalized impact factor. It then analyzes the distribution of journals’ scores, and the diminishing marginal difference between them. Finally, it examines the correlation between law schools’ positions in the U.S. News & World Report 2006 ranking and their flagship law reviews’ positions …
The Relative Value Of American Law Reviews: A Critical Appraisal Of Ranking Methods, Ronen Perry
The Relative Value Of American Law Reviews: A Critical Appraisal Of Ranking Methods, Ronen Perry
Ronen Perry
Ranking law reviews is not a novel initiative. Data regarding the relative value of legal periodicals was first published in 1930, in an article primarily concerned with the overall contribution of legal periodicals to the development of positive law. Since then many attempts have been made to rank American law reviews by various criteria. This Article, however, focuses not on actual rankings but on ranking theory and methodology. It offers an introductory discussion of the goals of law review rating, and the essential attributes of reliable and beneficial ranking methods, followed by a systematic and comprehensive analysis of the advantages …
