Yelp’S Review Filtering Algorithm, Yao Yao, Ivelin Angelov, Jack Rasmus-Vorrath, Mooyoung Lee, Daniel W. Engels

SMU Data Science Review

In this paper, we present an analysis of features influencing Yelp's proprietary review filtering algorithm. Classifying or misclassifying reviews as recommended or non-recommended affects average ratings, consumer decisions, and ultimately, business revenue. Our analysis involves systematically sampling and scraping Yelp restaurant reviews. Features are extracted from review metadata and engineered from metrics and scores generated using text classifiers and sentiment analysis. The coefficients of a multivariate logistic regression model were interpreted as quantifications of the relative importance of features in classifying reviews as recommended or non-recommended. The model classified review recommendations with an accuracy of 78%. We found that reviews …

Case Study: Using Crime Data And Open Source Data To Design A Police Patrol Area, Brent Allen

SMU Data Science Review

This case study examines how to use existing crime data augmented with open source data to design a patrol area. We used the a demand signal of "calls for service" vice reports which summarize calls for service. Additionally, we augmented our existing data with traffic data from Google Maps. Traffic delays did not correspond to traffic incidents reported in the area examined. These data were plotted geographically to aid in the determination of the new patrol area. The new patrol area was created around natural geographic boundaries, the density of calls for service and police operational experience.

Constructive Ambiguity And Judicial Development Of Insider Trading, Jill E. Fisch

SMU Law Review

The Texas Gulf Sulphur decision began what has become a fifty-year project of developing U.S. insider trading regulation through judicial law- making. During the course of that project, the courts developed a complex, fraud-based approach to determining the scope of liability. The approach has led, in many cases, to doctrinal uncertainty, a result that is reflected in the recent decisions in Newman, Salman, and Martoma.

In the face of this uncertainty, many commentators have called for a legislative solution. This article argues, however, that the true challenge of insider trading regulation is a lack of consensus about the appropriate scope …

Texas Gulf Sulphur And The Genesis Of Corporate Liability Under Rule 10b-5, Adam C. Pritchard, Robert Thompson

SMU Law Review

This Essay explores the seminal role played by SEC v. Texas Gulf Sulphur Co. in establishing Rule 10b-5’s use to create a remedy against corporations for misstatements made by their officers. The question of the corporation’s liability for private damages loomed large for the Second Circuit judges in Texas Gulf Sulphur, even though that question was not directly at issue in an SEC action for injunctive relief. The judges considered both, construing narrowly “in connection with the purchase or sale of any security,” and the requisite state of mind required for violating Rule 10b-5. We explore the choices of the …

A Texas Two-Step In The Right Direction—Looking Beyond Recent Legislation To Improve The Provision Of Special Education Services In Texas, Taylor Michals

SMU Law Review

This article analyzes the current state of the special education system in Texas following the 85th Legislative Session, focusing on the practical and legal implications of the limitation imposed by the Texas Education Agency in 2004 before analyzing Senate Bill 160, which requires Texas to remove the limitation on special education services, and its future impact on special education in Texas. Additionally, this article addresses Senate Bill 927, which outlined a plan to ensure that students who were previously denied services receive an adequate evaluation, why the legislation failed, and potential remedies for students who have been negatively impacted by …

The Coasian Firm And Insider Trading, Revisited, James C. Spindler

SMU Law Review

I present an economic model of insider trading building upon Haddock & Macey’s classic analysis of trading by the manager of a Coasian firm (i.e., a firm in which agency costs do not exist). Due to current shareholders’ status as expected sellers of shares, Coasian insider trading allows shareholders to expropriate outsiders via the managerial proxy and any signaling value of insider trading is eliminated by shareholders’ biased incentives. Adverse selection results. If a system of credible disclosure exists, an insider trading ban results in more disclosure, more efficient prices, and lower illiquidity costs. While the case for insider trading …

Presenting A Critical Perspective On “Economic Efficiency” In Law And Economics Courses, Gregory S. Crespi

SMU Law Review

“Law and Economics” courses are sometimes criticized for inadequately explaining the normative criterion of “economic efficiency” and then applying this criterion throughout the course in a superficial and biased manner that pejoratively labels most governmental market interventions and wealth redistribution measures as inefficient. These criticisms have merit, and in this article I point out a number of conceptual problems, empirical difficulties, and normative shortcomings of the economic efficiency criterion that students need to understand in order to be able to effectively counter policy arguments that rest upon dubious efficiency assessments.

The eight specific shortcomings of the economic efficiency criterion that …
