    Globalization and Focus in FT-50 OSCM Journals, 1952-2018: Implications for Academia
    (IUP Publications, 2021-11) Balakrishnan, Jaydeep; Kenworthy, Thomas P.; Cheng, Chun H.; Eliasson, Janice B.
    The study analysis enhances our understanding of the nature of Operations and Supply Chain Management (OSCM) authorship, scholarship globalization, international collaboration activity, research topics and trends, and research funding. Thus the authors expect the findings to be relevant to a variety of stakeholders including doctoral students, junior faculty, promotion and tenure committees, and business school administrators. For example, it has to be recognized that emphasizing publications in only the journals examined in this paper can be a risky strategy for those faculty in tenure track positions. Further it must be recognized that this strategy can be resource intensive for business schools.

    Bullwhip effect in the oil and gas supply chain : a multi-case study
    (Elsevier, 2019-11) Zhu, Tianyuan; Balakrishnan, Jaydeep; da Silveira, Giovani J. C.
    The bullwhip effect has been extensively studied in the retail, wholesale and manufacturing industries. However, it has been rarely explored in the context of resource extraction industries such as oil and gas, despite their economic impact and distinct features. This paper investigates the factors that impact the bullwhip effect in the oil and gas supply chain using case study evidence from six companies in North America, which cover refining and marketing, exploration and production, integrated oil and gas, and drilling. For each type of company studied, the operational causes of the bullwhip effect proposed in the literature and other factors of influence are examined. The findings indicate that the existing theories of the bullwhip effect have limitations in explaining the phenomenon in the oil and gas industry. Information sharing, a widely advocated countermeasure of the bullwhip effect may not be relevant in the integrated oil and gas company. Regarding the factors that drive or mitigate the bullwhip effect in different types of companies in the oil and gas supply chain, seven propositions are developed and several additional findings are obtained. All of these results enable better understandings of the bullwhip effect in academia, oil and gas organisations and related industries, and may provide guidance for potential countermeasures in practice.

    Pricing in C2C sharing platforms
    (2017-07-23) Angerer, Peter; Provin, Daniel; Zimmermann, Steffen; Nault, Barrie R.
    Sharing platforms such as Zilok.com enable the sharing of durable goods among consumers, and seek to maximize profits by charging transaction-based platform fees. We develop a model where consumers that are heterogeneous in their need to use a durable good decide whether to purchase and share (i.e., be a lender) or borrow (i.e., be a borrower), and a monopoly sharing platform decides on the platform fees. We find first that consumers with a greater need to use a durable good purchase and share, and that consumers with a lesser need borrow. Second, sharing platforms maximize profits only if the supply of a durable good matches demand – that is, the market must clear for platform fees to be profit maximizing. Third, the market-clearing condition requires that lender and borrower fees are classic strategic complements. Fourth, to maintain the market-clearing condition, sharing platforms have to increase their lender fee or decrease their borrower fee in response to increases in the sharing price, increases in usage capacity, and decreases in the purchase price of a durable good, and vice versa. These findings indicate that commonly applied one-sided pricing models in sharing platforms can be improved.
