   This study examines the resilience and sustainability of supply chains amid global disruptions, with a particular focus on the essential role of reverse logistics. Through a game-theoretic approach, we explore manufacturer decisions to source from either reliable but expensive raw materials or cost-effective yet riskier recycled or recyclable materials from the reverse logistics channel. Our analysis outlines three primary sourcing strategies: sourcing exclusively from suppliers (SS), sourcing solely through retailer reverse channel (RS), and a balanced dual sourcing (DS) approach. Our findings reveal the economic viability that recycling outsourcing is influenced by market demand and disruption risks. Notably, in scenarios of constrained market potential, the cost advantage of using recycled materials from less reliable reverse logistics channels surpasses the risks associated with supply chain disruptions, suggesting a complex cost-benefit landscape amidst supply uncertainties. Moreover, the stability of suppliers emerges as a pivotal factor in strategic sourcing decisions, underscoring the need to consider both economic efficiencies and supply reliability. The study also evaluates the dynamic competition between manufacturers and retailers, shedding light on how strategic adjustments driven by sustainability and resilience goals can enhance profitability and sustainability. It was found that despite the threat of disruptions, manufacturers benefit more from engaging with risky reverse channels under specific conditions, underscoring the nuanced decision-making required in uncertain supply scenarios. This research advances sustainable supply chain management by highlighting strategic complexities and the need for understanding economic efficiencies and supply stability, offering insights for navigating disruptions and fostering resilient, sustainable supply chains.

2. Forming Strategic Partnerships: New Results from the Revolutionizing Engineering and Computer Science Departments Participatory Action Research

   Margherio, C.; Doten-Snitker, K.; Williams, J.; Litzler, E.; and Ingram, E. (June 2018, American Society of Engineering Education Annual Conference)

   This research paper investigates the process of forming strategic partnerships to enact organizational change. There has been increasing interest in forming strategic partnerships in higher education due to a variety of motivations, such as pooling of resources and improving the professional development process for students (Worrall, 2007). It is important to examine how strategic partnerships form because the process of formation sets the objectives and expectations of the relationship, which in turn impact the likelihood of success and sustainability of the relationship. Further, despite the growing interest in forming strategic partnerships, the majority of these partnerships fail (Eddy, 2010). This analysis of strategic partnerships emerges from our participatory action research with university change agents activated through the NSF REvolutionizing engineering and computer science Departments (RED) Program. Through an NSF-funded collaboration between [University 1] and [University 2], we work with the change-making teams to investigate the change process and provide just-in-time training and support. Utilizing qualitative data from focus group discussions and observations of monthly cross-team teleconference calls, we examine the importance of motivations, social capital, and organizational capital in the process of forming strategic partnerships. We find that change-making teams have utilized a variety of strategies to establish goals and governance within strategic partnerships. These strategies include establishing alignment among institutional goals, project goals, and partner organization goals. Further, the strategic partnerships that have been most successful have occurred when teams have intentionally built mutually beneficial relationships and invited their partner into the visioning process for their change projects. These results delineate practices for initiating strategic partnerships within higher education and encourage faculty to build mutually beneficial strategic partnerships.

3. Fairness Interventions as (Dis)Incentives for Strategic Manipulation

   X. Zhang, M. Khalili (July 2022, International Conference on Machine Learning (ICML))

   Although machine learning (ML) algorithms are widely used to make decisions about individuals in various domains, concerns have arisen that (1) these algorithms are vulnerable to strategic manipulation and "gaming the algorithm"; and (2) ML decisions may exhibit bias against certain social groups. Existing works have largely examined these as two separate issues, e.g., by focusing on building ML algorithms robust to strategic manipulation, or on training a fair ML algorithm. In this study, we set out to understand the impact they each have on the other, and examine how to characterize fair policies in the presence of strategic behavior. The strategic interaction between a decision maker and individuals (as decision takers) is modeled as a two-stage (Stackelberg) game; when designing an algorithm, the former anticipates the latter may manipulate their features in order to receive more favorable decisions. We analytically characterize the equilibrium strategies of both, and examine how the algorithms and their resulting fairness properties are affected when the decision maker is strategic (anticipates manipulation), as well as the impact of fairness interventions on equilibrium strategies. In particular, we identify conditions under which anticipation of strategic behavior may mitigate/exacerbate unfairness, and conditions under which fairness interventions can serve as (dis)incentives for strategic manipulation.

4. Economies of Inequality? Polycentric Metropolitan Governance and Strategic Sustainability Choices

   https://doi.org/10.1177/10780874241252755  

   Deslatte, Aaron; Helmke-Long, Laura; Stokan, Eric; Chung, Juwon (May 2024, Urban Affairs Review)

   This article examines the relationship between the political fragmentation of cities in metropolitan regions, the distribution of social vulnerability, and the city-level economic and social sustainability strategies they adopt. Strategies emerge from prevailing community norms, and polycentric governance arrangements can support conditions in which both economic and social sustainability strategies emerge as compliments, contrary to the concern that fragmentation spurs zero-sum competition. Combining surveys of U.S. cities with social vulnerability data and text analysis of planning documents, we find that greater fragmentation has a negative impact on the sustainable development strategies cities adopt. However, growth and sustainable development strategies tend to develop alongside social sustainability efforts to address human needs. We conclude that development strategies emerge in polycentric systems in relation to the degree of fragmentation which exists, and that subsequent work should continue to focus on identifying these entropic thresholds in order to effectively address lingering inequities.

5. Deliberation during online bargaining reveals strategic information

   https://doi.org/10.1073/pnas.2410956122  

   Cotet, Miruna; Zhao, Wenjia_Joyce; Krajbich, Ian (February 2025, Proceedings of the National Academy of Sciences)

   A standard assumption in game theory is that decision-makers have preplanned strategies telling them what actions to take for every contingency. In contrast, nonstrategic decisions often involve an on-the-spot comparison process, with longer response times (RT) for choices between more similarly appealing options. If strategic decisions also exhibit these patterns, then RT might betray private information and alter game theory predictions. Here, we examined bargaining behavior to determine whether RT reveals private information in strategic settings. Using preexisting and experimental data from eBay, we show that both buyers and sellers take hours longer to accept bad offers and to reject good offers. We find nearly identical patterns in the two datasets, indicating a causal effect of offer size on RT. However, this relationship is half as strong for rejections as for acceptances, reducing the amount of useful private information revealed by the sellers. Counter to our predictions, buyers are discouraged by slow rejections—they are less likely to counteroffer to slow sellers. We also show that a drift-diffusion model (DDM), traditionally limited to decisions on the order of seconds, can account for decisions on the order of hours, sometimes days. The DDM reveals that more experienced sellers are less cautious and more inclined to accept offers. In summary, strategic decisions are inconsistent with preplanned strategies. This underscores the need for game theory to incorporate RT as a strategic variable and broadens the applicability of the DDM to slow decisions.
