Anderson Center for Sustainable Business, and co-director of the Diversity and Inclusion Fellows Program. “This cohort represented an excellent cross-section of the Institute. We are proud of the authenticity of this program thanks to the unique perspecties of the fellows.”
Bridging Surplus with Need: Improving Healthcare in the Developing World
As scholars of supply chain and operations management, we became interested in MSROs because we cared about the important work they do and because we were in the unique position to optimize the delivery of healthcare capabilities to resource-constrained healthcare facilities in the developing world. However, MSRO supply chains threw us for a loop. Why? Effective management of MSRO supply chains often cannot borrow from the common wisdom from product supply chains. Our expertise, and that of most industry experts, lies in for-profit supply chains. When selling to consumers within traditional operations, supply is controllable and demand is uncontrollable. For MSROs, the reverse is true. MSROs can’t control the timing and volume of donations, resulting in an uncertain quantity of supplies. Demand, on the other hand, is boundless.
Cobb and Toktay Take Carbon Reduction Challenge from Class to Co-op

Beril Toktay points out, “What’s most exciting about this program is that it teaches students they can be sustainable business champions no matter what their job function is. And even if students aren’t motivated to advance their careers towards a “sustainable business career,” they will still obtain tremendous benefits.” Part of the program’s design is to develop students’ skillsets in building a business case for a project, “selling” a project to management, and demonstrating that taking initiative from within a company can have excellent results for all parties. Having a stand-out internship experience to share will likely boost future employment prospects, as well.

This special issue implores us to address sustainability from the lens of emerging economies and the role that innovation can play in this context. We posit that, for sustainable operations research to be relevant in the context of emerging markets, it needs to incorporate social concerns and conditions, with an emphasis on inclusion and equity. Especially important for addressing social concerns in these economies will be product/service innovation, process/business model innovation, and supply chain innovation. We further posit that successful innovation in these areas will require collaboration with the public sector, civil society organizations, and communities. In this paper, we put forward “inclusive innovation” as a unifying approach that enables the collaborative integration of social issues in operations management decisions, particularly in emerging economies. We then focus on contemporary sectoral challenges in services, manufacturing, and agriculture, highlight the relevant social sustainability issues with an emphasis on those relevant to emerging economies, and point to new opportunities for research.

A key goal of Extended Producer Responsibility (EPR) legislation is to provide incentives for producers to design their products for recyclability. EPR is typically implemented in a collective system, where a network of recycling resources are coordinated to fulfill the EPR obligations of a set of producers, and the resulting system cost is allocated among these producers. Collective EPR is prevalent because of its cost efficiency advantages. However, it is considered to provide inferior design incentives compared to an individual implementation (where producers fulfill their EPR obligations individually). In this paper, we revisit this assertion and investigate its fundamental underpinnings in a network setting. To this end, we develop a new biform game framework that captures producers’ independent design choices (noncooperative stage) and recognizes the need to maintain the voluntary participation of producers for the collective system to be stable (cooperative stage).

We analyze a resource allocation problem faced by Medical Surplus Recovery Organizations (MSROs) that recover medical surplus products to fulfill the needs of under-served healthcare facilities in developing countries. Due to the uncertain, uncontrollable supply and limited information about recipient needs, delivering the right product to the right recipient in MSRO supply chains is particularly challenging. The objective of this study is to identify strategies to improve MSROs' value provision capability. In particular, we propose a mechanism design approach, and determine which recipient to serve at each shipping opportunity based on recipients' reported preference rankings of different products. We find that when MSRO inventory information is shared with recipients, the only truthful mechanism is random selection among recipients, which defeats the purpose of eliciting information. Consequently, we propose two operational strategies to improve MSROs' value provision: i) not sharing MSRO inventory information with recipients; and ii) withholding information regarding other recipients. We characterize the set of truthful mechanisms under each setting, and show that eliminating inventory and competitor information provision both improve MSROs' value provision. Further, we investigate the value of cardinal mechanisms where recipients report their valuations. We show that in our setting, eliciting valuations has no value added beyond eliciting rankings under a wide class of implementable mechanisms. Finally, we present a calibrated numerical study based on historical data from a partner MSRO, and show that a strategy consisting of a ranking-based mechanism in conjunction with eliminating inventory and competitor information can significantly improve MSROs...

We analyze product design implications of Extended Producer Responsibility (EPR)-based take-back leg islation on durable goods. In particular, we observe that durable product design incentives under EPR may involve an inherent trade-oﬀ that has not been explored to date: Durable goods producers can respond to EPR by making their products either more recyclable or more durable, where the former will decrease the unit recycling cost whereas the latter will reduce the volume the producer has to recycle. When these two design attributes do not go hand-in-hand, as is the case for many product categories, product design implications of EPR can be subtle. We ﬁnd that seemingly similar EPR implementation levers, namely recycling and collection targets, may have opposing eﬀects in driving producers’ design choices. Furthermore, more stringent legislative targets do not always guarantee improved product recyclability and durability. In particular, if the objective of EPR is to induce recyclable product designs, a low recycling target accompanied with a high collection target is preferred. On the other hand, if the objective of EPR is to induce durable product designs, a low collection target accompanied with a high recycling target is preferred.

Several auto manufacturers have recently introduced car sharing programs. Although the structure of most programs is the same, there is no clear dominant strategy for the type of vehicles that should be provided through car sharing. In this paper, we consider an original equipment manufacturer (OEM) that contemplates car sharing and designs its product line by accounting for the trade-off between driving performance and fuel efficiency under CAFE standards. Customers have different valuations of driving performance and decide whether to buy, join car sharing or rely on their outside options. We find that the OEM increases the fuel efficiency of the vehicles it provides through car sharing. This higher efficiency enables the OEM to charge a higher selling price to the higher end of the market, thus increasing its profit. This is especially beneficial to higher-end OEMs that face greater cannibalization and can explain why Daimler and BMW have been particularly active in introducing…

We analyze not‐for‐profit Medical Surplus Recovery Organizations (MSROs) that manage the recovery of surplus (unused or donated) medical products to fulfill the needs of underserved healthcare facilities in the developing world. Our work is inspired by an award‐winning North American non‐governmental organization (NGO) that matches the uncertain supply of medical surplus with the receiving parties’ needs. In particular, this NGO adopts a recipient‐driven resource allocation model, which grants recipients access to an inventory database, and each recipient selects products of limited availability to fill a container based on its preferences. We first develop a game theoretic model to investigate the effectiveness of this approach. This analysis suggests that the recipient‐driven model may induce competition among recipients and lead to a loss in value provision through premature orders. Further, contrary to the common wisdom from traditional supply chains, full inventory visibility…

The high cost of lenient return policies force consumer electronics original equipment manufacturers (OEMs) to look for ways to recover value from lightly used consumer returns, which constitute a substantial fraction of sales and cannot be resold as new products. Refurbishing to remarket or to fulfill warranty claims are the two common disposition options considered to unlock the value in consumer returns, which present the OEM with a challenging problem: How should an OEM dynamically allocate consumer returns between fulfilling warranty claims and remarketing refurbished products over the product’s life cycle? We analyze this dynamic allocation problem and find that when warranty claims and consumer returns are jointly taken into account, the remarketing option is generally dominated by the option of refurbishing and earmarking consumer returns to fulfill warranty claims. Over the product’s life cycle, the OEM should strategically emphasize earmarking of consumer returns at the…

In practice, we observe that some firms of durable or semidurable goods remanufacture their end-of-use products while others choose not to. Insofar as remanufacturing requires different competencies than manufacturing, whether to enter remanufacturing is a similar question as whether to enter any new business. At the same time, this decision has characteristics of a product line extension decision, as the remanufactured product has the same functionality as the corresponding...

Closed-loop supply chain (CLSC) management has evolved to be a mature area of supply chain management in its own right. Guide and Van Wassenhove (2009) describe how this research began with focusing on tactical and operational issues such as the disassembly of products or shop-floor control and coordination, and later started addressing issues pertaining to the entire reverse supply chain such as product acquisition, supply-chain contracting, and incentives. Recently, the literature has begun studying issues at the intersection of other disciplines, drawing on concepts from industrial ecology, studying marketing issues such as the pricing and positioning of new and remanufactured products, etc. It is clear that the research in CLSCs is moving in an interdisciplinary direction. This is of great value, as the “messier” problems in industry tend to require an interdisciplinary approach. At a recent workshop, invited industry participants shared the issues that they face in closing...

Take-back legislation based on Extended Producer Responsibility (EPR) holds producers responsible for proper end-of-life treatment of their products. In addition to diverting waste products from landfills, EPR legislation has the potential advantage of incentivizing eco-design of products. However, evidence suggests that product design outcomes of EPR legislation can be significantly influenced by its implementation. In this chapter, we survey the research on this topic, focusing on design impacts associated with several key operational considerations in supply chains. We show that intended design incentives under EPR legislation may be weakened, muted, or even negated as a result of operational factors such as design trade-off, market competition, and recycling resource sharing. Accordingly, we develop insights as to how the design potential of EPR legislation may be realized.
