  • A pragmatic clinical trial of hearing screening in primary care clinics: cost-effectiveness of hearing screening

    Cost Effectiveness and Resource Allocation

    Hearing loss is a high prevalence condition among older adults, is associated with higher-than-average risk for poor health outcomes and quality of life, and is a public health concern to individuals, families, communities, professionals, governments, and policy makers. Although low-cost hearing screening (HS) is widely available, most older adults are not asked about hearing during health care visits. A promising approach to addressing unmet needs in hearing health care is HS in primary care…

    Hearing loss is a high prevalence condition among older adults, is associated with higher-than-average risk for poor health outcomes and quality of life, and is a public health concern to individuals, families, communities, professionals, governments, and policy makers. Although low-cost hearing screening (HS) is widely available, most older adults are not asked about hearing during health care visits. A promising approach to addressing unmet needs in hearing health care is HS in primary care (PC) clinics; most PC providers (PCPs) do not inquire about hearing loss. However, no cost assessment of HS in community PC settings has been conducted in the United States. Thus, this study conducted a cost-effectiveness analysis of HS using results from a pragmatic clinic trial that compared three HS protocols that differed in the level of support and encouragement provided by the PC office and the PCPs to older adults during their routine visits. Two protocols included HS at home (one with PCP encouragement and one without) and one protocol included HS in the PC office.

    The cost-effectiveness analysis showed that the average cost per patient is highest in the patient group who completed the HS during their clinic visit, but the average cost per patient who failed the HS is by far the lowest in that group, due to the higher failure rate, that is, rate of identification of patients with suspected hearing loss. Estimated benefits of HS in terms of improvements in quality of life were also far greater when patients completed the HS during their clinic visit.

    Providing HS to older adults during their PC visit is cost-effective and accrues greater estimated benefits in terms of improved quality of life.

  • The Basis of Organization: Cells, Humans and Multi-Humans

    “Organizations” exist across different scales- molecules, viruses, single cells, multi-cellular living beings, and business firms. Building on the knowledge developed in basic sciences and social sciences, we present a framework to understand the similarities in the long-term strategies of all organizations. These similarities also guide the actions of both humans and groups of humans- companies, social movements and countries.

    “Organizations” exist across different scales- molecules, viruses, single cells, multi-cellular living beings, and business firms. Building on the knowledge developed in basic sciences and social sciences, we present a framework to understand the similarities in the long-term strategies of all organizations. These similarities also guide the actions of both humans and groups of humans- companies, social movements and countries.
    We start with the nature of competition. The largest source of uncertainty for any being comes from the actions of others that are the most similar to it. For football players, it is other football players, including team-members who play in the same position. For companies, it is other similar-sized companies in the same industry and geography.
    Is it better to cooperate rather than to compete? To lead a long and uneventful life, rather than a short and eventful one? This is why some of us cooperate and create organizations. However, we still need “safe” competitions to establish hierarchy and share rewards. These in-system competitions take real effort, but eliminate death (which happens in the “wild”). Nurture collegiate athletics. Buying paintings.
    This framework also explains other related topics- symbiotic beings, predators, scavengers, and death. It is a lens through which to understand current and emerging super-organizations. It also provides a set of rules to guide long-term strategy at all scales.

  • Leadership and Competition in Network Supply Chains

    Management Science

    This paper considers network supply chains with price dependent demand by modelling them as large acyclic networks. Such large networks are common in the automobile and apparel industries. We develop a model to analyze the effect of these large-scale problems involving long sequences of contracts, and show that contract leadership, as well as leader position in the network, affect the performance of the entire supply chain. We generalize Spengler (Spengler, J. 1950. Vertical integration and…

    This paper considers network supply chains with price dependent demand by modelling them as large acyclic networks. Such large networks are common in the automobile and apparel industries. We develop a model to analyze the effect of these large-scale problems involving long sequences of contracts, and show that contract leadership, as well as leader position in the network, affect the performance of the entire supply chain. We generalize Spengler (Spengler, J. 1950. Vertical integration and anti-trust policy. J. Political Econom. 58 347–352) to a game on a “contract tree” for a particular supply chain and extend the concept of double marginalization so that it can be applied in the form of a transformation to each contract that is offered by one member to another in the “contract tree.” We construct an algorithm to find the equilibrium solution, and derive the optimal location of the leader (“optimal” being the leader location that maximizes total supply chain profits). Our work formalizes many intuitive insights; for example, member profits are determined by systemwide rather than individual costs. Finally, we model Cournot competition between competing supply chains (both two heterogeneous trees and multiple identical trees) and show the effect of changes in leader position as well as cost structure on the equilibrium.

  • Leader Location, Cooperation and Coordination in Serial Supply Chains

    Production and Operations Management Journal

    In this paper we study multi-stage serial supply chains with price dependent deterministic demand and increasing marginal costs. We analyze the effect of contract leadership (i.e. the ability to offer wholesale price and two-part tariff contracts) on the supply chain performance and use that as a basis
    to study coordination and cooperation. There is strong evidence of first-mover advantage in wholesale price contracting which is amplified when the chain is coordinated using two-part tariff…

    In this paper we study multi-stage serial supply chains with price dependent deterministic demand and increasing marginal costs. We analyze the effect of contract leadership (i.e. the ability to offer wholesale price and two-part tariff contracts) on the supply chain performance and use that as a basis
    to study coordination and cooperation. There is strong evidence of first-mover advantage in wholesale price contracting which is amplified when the chain is coordinated using two-part tariff contracts. We analyze cooperation and the implications of leader location in uncoordinated chains. Our results demonstrate the importance of considering the entire sequence of successive contracts when assessing the performance of a supply chain. We find that in some cases an ineffcient supply chain may have a natural tendency to reduce ineffciency through cooperation between non-leader members.

  • Competition in Remanufacturing

    Production and Operations Management Journal

    We present a two-period model of remanufacturing in the face of competition. In our model, an original equipment manufacturer (OEM) competes with a local remanufacturer (L) under many reverse logistics configurations for the returned items.
    After establishing the Nash Equilibrium in the second period sub-game, we use numerical experiments for comparative statics. OEM wants to increase L's remanufacturing cost. Surprisingly, while L competes in the sales market, she has incentives to reduce…

    After establishing the Nash Equilibrium in the second period sub-game, we use numerical experiments for comparative statics. OEM wants to increase L's remanufacturing cost. Surprisingly, while L competes in the sales market, she has incentives to reduce OEM's remanufacturing cost.
    A social planner who wants to increase remanufacturing can give incentives to the OEM to increase the fraction available for remanufacturing, or reduce his remanufacturing costs.
