INFORMS 2016 Presentations

Come show me some love in Nashville. Here are my presentations:

1. Session MC29 – Issues in Energy Efficiency and Renewable Energy
November 14, 2016, 1:30 – 3:00 PM, 202A-MCC
3rd Presentation (of 3): Mind The Gap: Coordinating Energy Efficiency And Demand Response
Authors: Eric Webb, Owen Wu, Kyle D. Cattani, Kelley School of Business, Indiana University
Abstract: Traditionally, energy demand-side management techniques, such as energy efficiency (EE) and demand response (DR), are evaluated in isolation. We examine the interactions between long-term EE upgrades and daily DR participation at an industrial firm. We find that EE and DR act as substitutes in terms of reduction of peak electricity demand, and the long-studied energy efficiency gap between firm-optimal and societal-optimal levels of EE is smaller when DR is considered. We suggest three approaches to reducing the energy efficiency gap, including an original suggestion that relies upon the interactions between EE and DR.

2. Session TC34 – Public Policy and Healthcare Operations
November 15, 2016, 1:30 – 3:00 PM, 204-MCC
2nd Presentation (of 3): Predicting Nurse Turnover And Its Impact On Staffing Decisions
Authors: Eric Webb, Kurt Bretthauer, Kelley School of Business, Indiana University
Abstract: Nurse turnover remains a significant problem in skilled nursing facilities across the United States. High turnover leads to two important questions: (1) Hiring decisions – What applicant attributes should be valued when hiring nurses, in order to hire nurses that are effective at their jobs and likely to stay for a long duration? (2) Staffing decisions – How should nurse workload be managed in order to prevent burnout and decrease turnover? Based on a large dataset from skilled nursing facilities in the United States, we first use a survival model to predict nurse turnover. For this talk we then focus on staffing and incorporate these empirical results into analytical models for nurse staffing decisions.

3. Session WC31 – Consumer Behavior in Services
November 16, 2016, 12:45 – 2:15 PM, 202C-MCC
4th Presentation (of 4): Linking Customer Behavior And Delay Announcements: Are Customers Really Rational?
Authors: Eric Webb, Qiuping Yu, Kurt M. Bretthauer, Kelley School of Business, Indiana University
Abstract: We empirically explore customer abandonment behavior in the presence of delay information using data from a call center. Previous work has assumed that customers are at least partially rational in responding to announcements. In contrast, we relax all rationality assumptions. Our findings indicate that customers exhibit loss aversion behavior. In addition, customers may update their announcement-induced reference point as they hear subsequent announcements. Our results also indicate that customers may fall for the sunk cost fallacy while waiting in the queue. We show the impact of these effects on staffing decisions using a classic staffing model.

4. Session WE32 – Sports and Entertainment
November 16, 2016, 4:30 – 6:00 PM, 203A-MCC
3rd Presentation (of 4): Using Past Scores And Regularization To Create A Winning NFL Betting Model
Authors: Eric Webb, Kelley School of Business, Indiana University, and Wayne L. Winston, Bauer College of Business, University of Houston
Abstract: Is the National Football League betting market efficient? We have devised a profitable betting model that would win 52.7% of the 7,705 bets against the spread it would have made over 34 seasons. Scores from previous weeks are used to estimate the point value of each team’s offense and defense. These values predict next week’s scores, and a bet is placed against the advertised spread. The sum of squares of offensive/defensive point values are constrained to be less than a regularization constant.
