4 - How to Make Envy Vanish Over Time Christos-Alexandros Psomas, Carnegie Mellon University, 5000 Forbes Avenue, GHC 9116, Pittsburgh, PA, 15213, United States, Gerdus Benade, Aleksandr Mark Kazachkov, Ariel Procaccia We study the dynamic fair division of indivisible goods. Suppose T items arrive online and must be allocated upon arrival to one of n agents, each of whom has a value in [0,1] for the current item. Our goal is to design allocation algorithms that minimize the maximum envy at time T, defined as the maximum difference between any agent’s overall value for items allocated to another agent and to herself. ?n algorithm has vanishing envy if the ratio of envy over time goes to zero as T goes to infinity. We design a polynomial-time, deterministic algorithm that achieves vanishing envy, and show that it is asymptotically optimal. We also derive tight bounds for a more general setting where items arrive in batches. n TB54 North Bldg 232B Issues in Behavioral Operations Sponsored: Behavioral Operations Management Sponsored Session Chair: Elena Katok, University of Texas at Dallas, Richardson, TX, 75080, United States 1 - The Behavioral Traps of Making Multiple, Simultaneous, Newsvendor Decisions This paper conducted an experimental study to explore behaviors of newsvendors who make order decisions for two products simultaneously. We find that the decision performance is significantly reduced if a high-margin product is grouped with a low-margin product, but not so if it’s grouped with another high-margin product. Our study has implication on how multiple products should be grouped and managed. 2 - Using Strategic Buckets for Aligning Managers’ Decisions with Companies’ Objectives Ulrich Thonemann, Professor, Universitat zu Koln, Business School, Albertus Magnus Platz, Koeln, D-50923, Germany, Andreas Fuegener From a company’s perspective, managers tend to over-invest in incremental projects and to under-invest in innovative ones. We analyze how strategic buckets can be used for aligning the investment decisions of individual managers with the company’s objectives. Strategic buckets have been implemented in practice, but it is unclear how managers respond to them and how companies should design them. We present a behavioral model and report the results of laboratory Shan Li, City University of New York, Baruch College, 55 Lexington Avenue, New York, NY, 10010, United States, Kay-Yut Chen

split into two 10-minute quarters; and (4) resetting the shot clock to 20 (vs 30) seconds after an offensive rebound. In anticipation of the next possible rule change in 2019, this analysis quantifies the effect of these modifications on the college basketball game, through comparison with regular season and other post- season tournament games. 2 - Age Effects in Mixed Martial Arts Competition Thomas Robbins, East Carolina University, 3212 Bate Building, Greenville, NC, 27858, United States The impact of age on sports performance has been analyzed in multiple sports including baseball, hockey, soccer, swimming, golf, track and field, and tennis. In this talk, we examine the impact age has on performance in mixed martial arts competition. We find that the age distribution varies significantly with weight class; as smaller more athletic weight classes are younger than the larger weight classes. We also quantify the impact age and age differential have on a fighter’s probability of winning. Finally, we investigate whether the age distribution has been impacted by anti-doping policies and USADA testing. 3 - MeetOpt: A Spreadsheet-based Decision Support System for Optimal Athlete-to-Event Assignment in Track and Field Matthew Bailey, Bucknell University, School of Management, Taylor Hall, Lewisburg, PA, 17837, United States, Maciek A. Nowak Nationally, track and field is second only to football in participation. Time- constrained track coaches primarily focus on the training and development of athletes. As a result, they overlook and underappreciate the competitive advantage of strategically assigning athletes to events. Working with local coaches, we developed a spreadsheet-based DSS, MeetOpt. MeetOpt is a generalization and extension of an assignment problem which determines an optimal athlete assignment to maximize the expected total team points. We illustrate the value of this model in comparison to commercially available tools and under a variety of scenarios, league rules, and preferences. 4 - Team-specific Ticket Options Ovunc Yilmaz, University of Notre Dame, South Bend, IN, 46617, United States, Mark Ferguson, Pelin Pekgun, Guangzhi Shang Team-specific ticket options have recently gained popularity in the sports industry. In this study, we investigate the drivers of prices and transaction volumes in this market using social media data and detailed game/ranking information. n TB56 West Bldg 101A HAS Distinguished Scholar Lecture – Stefan Scholtes Sponsored: Health Applications Sponsored Session Chair: Ebru Korular Bish, Virginia Tech, Blacksburg, VA, 24060, United States Co-Chair: Tinglong Dai, Johns Hopkins University, Baltimore, MD, 21202, United States 1 - The Healthcare Management Department of Management Science: How Can we Create and Support Impactful Research? Stefan Scholtes, University of Cambridge, Judge Business School, Trumpington Street, Cambridge, CB2 1AG, United Kingdom In contrast to other Management Science departments, the new healthcare management department focuses on a specific industry. This should be attractive to authors because their papers do not need to address a general context or contribute to general theory. However, the luxury comes at a price: Papers in the department have to provide insights that are of immediate interest and relevance for senior leaders in the industry. I will discuss this challenge, provide a few illustrative examples of attempts from my own work, and would then like to hear from the audience how we can achieve more practical impact with our research, while maintaining the high methodological standards of Management Science.

Elena Katok, University of Texas at Dallas, 800 W. Campbell Rd., Jindal School of Management (SM30), Richardson, TX, 75080, United States, Tobias Stangl, Gary E. Bolton In procurement interactions, the relationship between the buyer and the seller starts after the sourcing decision has been made. In this study we consider ways to design a scorecard to best incentivize the suppliers.
