Oskar Harmon and Paul Tomolonis (UConn PhD 2017) co-authored the article “The effects of using Facebook as a discussion forum in an online Principles of Economics course: Results of a randomized controlled trial”
Their paper makes a comparison between using social media or traditional Course Management System (CMS) discussion groups in a fully online Principles of Microeconomics course.
Students were randomly assigned to a discussion forum in either Facebook or CMS to discern a difference in the level of engagement and learning outcomes. The popular hypothesis is that students using social media have greater engagement with the class and higher learning outcomes relative to students using a CMS platform. Reasons for the positive effect include the ease of use and student familiarity with social media, which allows them to make more connections and gain a deeper understanding of the course material through discussions with others.
Contrary to the widely held view, the results of this study suggest that participation in the treatment Facebook group is associated with declining student engagement and a reduction in the semester course average of 3 to 5 points on a 100-point scale.

Panel Discussion, Stamford Campus
The annual Alumni Networking Panel, co-organized by Stamford Campus Economics Faculty, CLAS Alumni Relations, and UConn Foundation, was held March 26, 2019.
The panelists, all UConn alumni, shared stories about their UConn education to the contribution to their career paths. Mr. Bianchi (majored in Economics) shared that he arrived as a UConn freshman majoring in pre-med, and his class in Principles of Macroeconomics with Professor Polly Allen forever changed his career path, and the skills learned in the Econometrics course taught by Professor Subhash Ray sparked a lifelong interest in quantitative analysis.
Mr. Regan (majored in Economics) shared that his choice of major was inspired by Professor Derek Johnson’s Principles of Microeconomics course, and the Socratic teaching style in Professor Paul Tomolonis’s course in International Economics.
Ms. Daley, and Ms. Pierre-Louis (Public Policy and Psychology majors) shared that from their courses in statistics and computer programming they developed skills core to their successful career paths. Professor Harmon served as panel moderator.

High Dimensional Econometrics and Identification, by Professor Chihwa Kao and co-author Long Liu, will be coming out in May.
From the Publisher:
In many applications of econometrics and economics, a large proportion of the questions of interest are identification. An economist may be interested in uncovering the true signal when the data could be very noisy, such as time-series spurious regression and weak instruments problems, to name a few. In this book, High Dimensional Econometrics and Identification, we illustrate the true signal and, hence, identification can be recovered even with noisy data in high-dimensional data, e.g., large panels. High-dimensional data in econometrics is the rule rather than the exception. One of the tools to analyze large, high-dimensional data is the panel data model.
High Dimensional Econometrics and Identification grew out of research work on the identification and high-dimensional econometrics that we have collaborated on over the years, and it aims to provide an up-to-date presentation of the issues of identification and high-dimensional econometrics, as well as insights into the use of these results in empirical studies. This book is designed for high-level graduate courses in econometrics and statistics, as well as used as a reference for researchers.
- Panel Data Model with Stationary and Nonstationary Regressors and Error Terms
- Panel Time Trend Model with Stationary and Nonstationary Error Terms
- Estimation of Change Points in Stationary and Nonstationary Regressors and Error Term
- Weak Instruments in Panel Data Models
- Incidental Parameters Problem in Panel Data Models
Readership: Graduate and researchers in the field of econometrics and economics.
The Department of Economics will be sponsoring a session at the 33rd New England Statistics Symposium (NESS) on May 15–17, 2019.
High Dimensional Econometrics
The technological innovations in information processing and the increased storage capability have made possible to collect very large data sets in various fields of economics and finance.
This session puts together 3 papers that present state-of-the-art techniques to deal with high dimensional issues in econometrics.

Professor Stephen Ross’s paper “Partners in Crime,” examining the effect of neighborhoods and school on criminal partnerships, was featured this past week in the AEA Research Highlights
The full paper was published last month in the American Economic Journal: Applied Economics.
Professor Subhash Ray’s paper THE TRANSFORMATION FUNCTION, TECHNICAL EFFICIENCY, AND THE CCR RATIO is forthcoming in a special issue of European Journal of Operational Research commemorating the introduction of Data Envelopment Analysis (DEA) into the Operations Research/Management Science literature forty years back by Charnes, Cooper, and Rhodes (CCR). European Journal of Operational Research is a highly rated peer reviewed journal with an impact factor of 3.426 and a 5-year impact factor 0f 3.96.
DEA is a nonparametric method of evaluating productive efficiency without assuming any explicit production, cost, or profit function. It is particularly useful for benchmarking the performance of non-commercial organizations like schools, hospitals, police departments, etc.
Professor Ray has been an active researcher in this area for decades and is internationally recognized for his book Data Envelopment Analysis written from the viewpoint of neoclassical production economics. Published in 2004 by Cambridge University Press, it continues to be a major reference/textbook for serious researchers. In 2016 he received the W.W. Cooper Lifetime Contribution Award from the International DEA Society (iDEAs).
