WA03C Grand Ballroom C Empirical Research in New Product Development and Innovation Sponsored: Manufacturing & Service Oper Mgmt Sponsored Session Chair: Necati Tereyagoglu, Georgia Institute of Technology, Atlanta, GA, 30308, United States, necati.tereyagoglu@scheller.gatech.edu Co-Chair: Karthik Ramachandran, Georgia Institute of Technology, Atlanta, GA, 30308, United States, karthik.ramachandran@scheller.gatech.edu 1 - Upstream Versus Downstream Experience in Crowdsourcing Platforms with Interdependent Problem Domains: An Empirical Investigation Anant Mishra, George Mason University, Fairfax, VA, 22030, United States, amishra6@gmu.edu, Nirup M.Menon, Shun Ye Using detailed archival data from TopCoder, a crowdsourcing platform that hosts contests across software development problem domains (e.g., architecture, design, testing), we use a classification scheme to represent a contestant’s experience in related problem domains on the crowdsourcing platform and examine how it impacts her performance in a contest. 2 - Revisiting the Role of Collaboration in Creating Breakthrough Inventions Tian Chan, Assistant Professor, Emory University’s Goizueta Business School, 1300 Clifton Road, Atlanta, GA, 30322, United States, tian.chan@emory.edu, Jurgen Mihm, Manuel Sosa Using utility and design patents, we compare the effects of working alone (vs. teams) on the probability of creating breakthrough inventions. Working alone lowers performance, consistent with literature. But we also find that this performance disadvantage disappears for design. We find empirical support that the difference is due to the holisticness of design. Finally, we show that lone inventors with a large number of past collaborators significantly improve their propensity to create breakthrough innovations to the point that they outperform teams for holistic inventions. 3 - Employee Mobility and Process Innovation in Manufacturing Philipp Cornelius, UCL.School of Management, London, United Kingdom, philipp.cornelius.12@ucl.ac.uk, Bilal Gokpinar, Fabian J. Sting Regular employees can be a good source of innovative ideas to improve operational efficiency. We empirically investigate how mobility affects the innovation value created by the employees. We examine the immediate and long term (static and dynamic) implications as well as the role of direction of employee moves on innovation outcomes. 4 - Help or Hindrance? the Role of Familiarity in Collaborative Product Development Murat Unal, Georgia Institute of Technology, Scheller College of Business, 800 West Peachtree Street, Atlanta, GA, 30308, United States, Murat.Unal@scheller.gatech.edu, Karthik Ramachandran, Necati Tereyagoglu We study whether the impact of team familiarity on the outcome of a creative process differs when individuals have design and managerial roles in a video game development setting based on data of the complete careers of 13,230 individuals and 752 different video games. We find that familiarity among individuals who perform design tasks has a detrimental effect on the final performance, while higher familiarity among producers (managers) strengthens the final performance. We also analyze the impact when the source of familiarity is different from or similar to the members’ current roles. 320A Sustainability Issues in Supply Chains Sponsored: Manufacturing & Service Oper Mgmt, Sustainable Operations Sponsored Session Chair: Xi Chen, University of Michigan-Dearborn, Dearborn, MI, 48128, United States, xichenxi@umich.edu 1 - Green Technology Development and Adoption: Competition, Regulation, and Uncertainty - A Global Game Approach Xin Wang, Hong Kong University of Science and Technology, Kowloon, Hong Kong, xinwang@ust.hk, Soo-Haeng Cho, Alan Scheller-Wolf WA04

When a government is considering tightening a standard on a pollutant, their decision often is influenced by the number of firms being able to meet the tightened standard, because a higher number indicates a more feasible standard. We study how such regulation may affect a firm’s incentive to develop a new technology to reduce a pollutant. To analyze this problem, we use the global game framework recently developed in economics. We find that regulation that considers industry capability, compared with regulation that ignores it, can more effectively motivate development of a new green technology. Surprisingly, uncertainty in the payoff can also help promote development of a new green technology. 2 - Does Supply Chain Visibility Affect Operating Performance? Evidence from Conflict Minerals Disclosures Caroline Swift, Pennsylvania State University, University Park, PA, United States, cas669@smeal.psu.edu, Suresh Muthulingam, V. Daniel Guide Firms face the challenge of identifying and monitoring members across their supply chains because they are increasingly held responsible for their supply chain partners’ actions. Consequently, supply chain visibility (SCV) is essential to mitigate risks in supply chains. We use data from the U.S. conflict mineral disclosure legislation to assess the extent of firms’ visibility across their supply chains. Then, we compare the operating performance of firms with high SCV against those with low SCV. We find that firms with higher SCV benefit from improved profitability, productivity, and sales. 3 - Green Sourcing: the Role of Premium Sharing and Consulting Services Xi Chen, University of Michigan-Dearborn, 2290 Engineering Complex, 4901 Evergreen Rd, Dearborn, MI, 48128, United States, xichenxi@umich.edu, Niyazi Taneri, Saif Benjaafar Certified sustainable products often times enjoy a significant green premium in the retail market. In this paper, we study a retailer’s use of premium sharing and consulting service offers to incentivize suppliers to exert greening efforts, which improve the chances of receiving certification and in turn capture the green premium. We also examine the case where the retailer has incomplete information about the supplier’s cost of greening efforts. 4 - Compete Versus Cooperate? A Strategic Game Behind the EV Standards War This paper studies the strategic choice facing two EV manufacturers in light of the standards war currently staged in the EV industry on whether to compete or cooperate in the development and deployment of an extensive EV charging network (a key complementary asset that helps mitigate EV range anxiety). We show that the strategic choice of standardizing EV charging systems has the offsetting effects on EV production volumes and profits. The degree of product differentiation in the EV is the key driver of the private incentives to cooperate in the provision of the complement as well as overall industry diffusion of the EV. 320B Data-driven Modeling in Healthcare Service Sponsored: Health Applications Sponsored Session Chair: Nan Kong, Purdue University, West Lafayette, IN, 47906-2032, United States, nkong@purdue.edu Co-Chair: Mingyang Li, Tampa, FL, 33647, United States, mingyangli@usf.edu Co-Chair: Hambisa Keno, BAE Systems, Burlington, MA, United States, hambisa.keno@gmail.com 1 - Bayesian Fall Risk Assessment for Older Adults in Assisted Living Facilities Suiyao Chen, University of South Florida, 5017 Patricia Court, Apt 237, Tampa, FL, 33617, United States, suiyaochen@mail.usf.edu, William D. Kearns, James L. Fozard, Mingyang Li Fall is a devastating critical event with high incidence and mortality rate among older adults in USA. Existing approaches mainly focused on population-level modeling and evaluated average fall frequency in a certain time period. To account for individual heterogeneity of fall occurrences and provide instantaneous assessment of fall risk over time, this paper proposes a personalized fall risk assessment model using Bayesian approaches. Different performance indices are presented to evaluate fall characteristics of individuals. A real case study based on fall records from Florida assisted living facilities is provided to illustrate the proposed work and demonstrate its effectiveness.
