EWEPA is a major biennial conference on the topics of productivity, efficiency and performance analysis. We expect a very large number of participants to attend, from a wide international community. Presentations are invited on the theory and application of economics, econometrics, statistics, management science and operational research to various problems in the areas of productivity and efficiency. All popular techniques and methodologies will be represented, including stochastic frontier analysis, data envelopment analysis, bootstrapping approaches, and many more. We also welcome papers on broader issues related to measuring, understanding, incentivising and improving the productivity and performance of firms, public services and industries.

November 14 – Informs Annual Meeting – Insights from Machine Learning for Evaluating Production Function Estimators on Manufacturing Survey Data
I have presented this paper at several conferences recently.
Abstract: In this paper we propose selecting an estimator based on a weighting of its in-sample and predictive performance on actual application datasets. For simulated data, we find that our proposed estimator has the lowest weighted errors. For actual data, specifically the 2010 Chilean Annual National Industrial Survey, a Cobb-Douglas specification describes at least 90% as much variance as the best alternative estimators in practically all cases considered.
November 13-16 – Informs Annual Conference – Nashville, TN
The INFORMS 2016 Annual Meeting will take place in the Music City Center, the state-of-the-art convention center recently built, and the adjacent Omni Nashville Hotel. The conference will feature plenaries and keynotes; panel discussions; tutorials; and thousands of oral and poster presentations from leading academics, industry experts, students, and representatives of government agencies. This Annual Meeting will provide the attendees numerous opportunities to share expertise and experiences; find prospective employers and employees; and build professional networks by meeting new people and reconnecting with colleagues.
October 15-19 – CICMHE Fall Meeting – Tucson AZ
The College-Industry Council on Material Handling Education (CICMHE) held its bi-annual business meeting October 15th and 16th in Tucson, Arizona. CICHME is an academic/industry council of the Material Handling Industry (MHI) that promotes increased awareness of material handling and logistics through a variety of educational and research activities. The council is organized into two working committees: Events and Projects.
September 23-24 – Conference on Advances in Big Data Modeling, Computation and Analytics – Texas A&M University
The Conference on Advances in Big Data Modeling, Computation and Analytics was held at Texas A&M University on September 23 and 24 featuring a variety of academic and industry talks. A highlight of the event was a keynote talk by Michael Jordan, the abstract is included below.
On Computational Thinking, Inferential Thinking and Data Science
Michael I. Jordan, University of California, Berkeley
ABSTRACT
The rapid growth in the size and scope of datasets in science and technology has created a need for novel foundational perspectives on data analysis that blend the inferential and computational sciences. That classical perspectives from these fields are not adequate to address emerging problems in “Big Data” is apparent from their sharply divergent nature at an elementary level—in computer science, the growth of the number of data points is a source of “complexity” that must be tamed via algorithms or hardware, whereas in statistics, the growth of the number of data points is a source of “simplicity” in that inferences are generally stronger and asymptotic results can be invoked. On a formal level, the gap is made evident by the lack of a role for computational concepts such as “runtime” in core statistical theory and the lack of a role for statistical concepts such as “risk” in core computational theory. I present several research vignettes aimed at bridging computation and statistics, including the problem of inference under privacy and communication constraints, and ways to exploit parallelism so as to trade off the speed and accuracy of inference.
September 15 – Federal Statistical System Research Data Center Conference – Texas A&M University
The Texas Research Data Center (RDC) hostied the 2016 FSRDC Research Conference on September 15, 2016. The Texas RDC is supported by a multi-university consortium involving Texas A&M University, Texas A&M University System, Baylor University, Rice University, The University of Texas at Austin and The University of Texas at San Antonio. The conference was a day of concurrent paper and poster sessions and a keynote presentation. Sessions were based on current or recent research using data from the nationwide network of RDCs. Themes include, research topics from the fields of economics, business and management, demography, and health and developments in data sets. Papers and posters involved statistical analyses on nonpublic versions of data sets available from the U.S. Census Bureau, the National Center for Health Statistics, the Agency for Healthcare Research and Quality, and other federal statistical agencies.
