Professor Kao Publishes High Dimensional Econometrics and Identification

Posted on March 28, 2019 by McConnel, Mark

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.

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.

List of invited speakers:

(1) Fa Wang, Cass Business School, Fa.Wang@city.ac.uk, “Maximum Likelihood Estimation and Inference for High Dimensional Nonlinear Factor Models with Application to Factor-augmented Regressions”

(2) Yuan Liao, Rutgers Economics, yuan.liao@rutgers.edu, “Inference for Heterogeneous Effects Using Low Rank Estimation”

(3) Min Seong Kim, UConn Economics, min_seong.kim@uconn.edu, “Policy Analysis Using Panel and Multilevel Models with Group Interactive Fixed Effects”

Discussant: Jungbin Hwang, UConn Economics, jungbin.hwang@uconn.edu

Session Chair: Chihwa Kao, UConn Economics, chih-hwa.kao@uconn.edu

Professor Ross’s Research Featured in AEA Research Highlights

Posted on February 18, 2019 by McConnel, Mark

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 Publishes in European Journal of Operational Research

Posted on February 18, 2019 by McConnel, Mark

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).

Professor Prakash receives “World Bank Economic Review Excellence in Refereeing Award”

Posted on January 21, 2019 by McConnel, Mark

Professor Nishith Prakash has received the “World Bank Economic Review Excellence in Refereeing Award”, recognizing his service to the journal World Bank Economic Review.

About the Journal

The mission of The World Bank Economic Review is to encourage and support research in the field of development economics. We seek to publish and disseminate innovative theoretical and empirical research that identifies, analyzes, measures, and evaluates the macro and micro-economic forces that promote or impede economic development with a view towards providing the knowledge necessary for designing, implementing, and sustaining effective development policies in low and middle income countries. Our intended audience comprises a worldwide readership of economists and other social scientists in government, business, international agencies, universities, and research institutions.

Professor Ross in American Economic Journal: Applied Economics

Posted on January 21, 2019 by McConnel, Mark

Professor Ross, with coauthors Billing and Deming, finds strong evidence of very localized neighborhood effects in both the commission of crimes and the creation of criminal partnerships among older teenagers and young adults (within 1/2 KM).

These localized effects appear to facilitated by relationships created within schools, and do not exist between youth who live very close to each other, but were resided on opposite sides of the same school attendance zone.

UConn-Stamford FED Challenge Team Earns Honorable Mention at Competition in NYC

Posted on January 10, 2019January 10, 2019 by McConnel, Mark

The UConn-Stamford FED Challenge team earned honorable mention in the Federal Reserve Bank of New York 2018 College FED Challenge competition. This marked the third consecutive year of participation in the competition by the Stamford Campus team and the first time advancing to the semi-final round. The competition started with 39 teams in the initial round on October 24. The UCONN-Stamford team advanced to the semi-final round held on November 14 among only eight teams. Rutgers University-New Brunswick placed first and advanced to the final round held in Washington DC November 29. Columbia University placed second. UConn-Stamford earned Honorable Mention along with Fairfield University, Fordham University, Siena College, and SUNY-Oneonta.

The College Fed Challenge is a team competition for undergraduate students. Teams analyze economic and financial conditions and formulate a monetary policy recommendation, modeling the Federal Open Market Committee. The Federal Reserve Bank of New York is one of four Federal Reserve Banks that host the College Fed Challenge Competition. The regional winners go to the final round at the Board of Governors in Washington D.C.

UCONN-Stamford team was comprised of 3 presenters: Ignacio Gonzalez, Jonathan Herrick, and Brendan Armburst-Mulcahey. The team coach was Di Yang, (Stamford Business School MBA). The researchers who helped prepare the team for the competition were Aditya Dadavai, Sijie Hu, Lingyi Zhu, and Roma Roma (all in the Stamford Business School BPMA Program). Faculty advisors were professors Natalia Smirnova, Steven Lanza, Kanda Naknoi, and Oskar Harmon. The team benefited from practice sessions of challenging questions with volunteer members of the Fairfield Business Community.
