• A Hidden Markov Model to Detect On-Shelf Out-of-Stocks Using Point-of-Sale Data AI翻译
  作者：Montoya, Ricardo; Gonzalez, Carlos
  作者单位：Universidad de Chile
  摘要：We propose a hidden Markov model (HMM) approach to identifying on-shelf out-of-stock (OOS) by detecting changes in sales patterns resulting from unobserved states of the shelf. We calibrate our model using point-of-sale (POS) data from a big-box retailer. We validate our approach using visual inspections that monitor the state of the shelf and compare them to the HMM's predictions. We test the proposed approach on 14 products and 10 stores. We specify our model using a hierarchical Bayes appro...
• The Effects of Ecolabels and Environmental Regulation on Green Product Development AI翻译

  摘要：Problem definition: We develop a framework for studying the impact of voluntary ecolabels and mandatory environmental regulation on green product development among competing firms. Academic/practical relevance: We contribute to the academic literature on environmental quality competition by explicitly accounting for the credibility of environmental claims made by firms, and by exploring the implications for society of two mechanisms used to remedy credibility-related consumer discounting of fi...
• Dynamic Pricing of Limited Inventories with Product Returns AI翻译

  摘要：Many online retail channels face high rates of product returns. This poses a new challenge to the sellers' dynamic pricing problem when some returns in good condition can be resold in the selling season. To study the impact of product returns and guide sellers in adjusting pricing policies, we build a product return model by augmenting the classic monopolist's dynamic pricing framework. We show that the return dynamics can complicate the problem by making it generally not Markovian. We address...
• Strategic Inventory and Supplier Encroachment AI翻译

  摘要：Problem definition: In a two-period model of a dyadic supply chain, we study the interaction between the use of strategic inventory withholding by the buyer and the use of a direct selling channel (encroachment) by the supplier in the second period. Academic/practical relevance: While the extant OM literature has individually examined the two strategies, the system-wide combined effect of these strategies has not been studied. Methodology: We fill the gap by building and analyzing two decentra...
• Heterogeneity of Reference Effects in the Competitive Newsvendor Problem AI翻译

  摘要：This paper demonstrates the mathematical equivalence between two recently proposed reference effect formulations for the newsvendor problem and then extends them to a competitive setting. The analysis of the resultant game shows that the heterogeneity of reference effects can explain multiple regularities observed in recent experimental studies of newsvendor competition. In particular, our model explains the main experimental finding that one newsvendor tends to ignore the policy of its compet...
• Using Patient-Specific Quality Information to Unlock Hidden Healthcare Capabilities AI翻译
  作者：Wang, Guihua; Li, Jun; Hopp, Wallace J.; Fazzalari, Franco L.; Bolling, Steven F.
  作者单位：University of Michigan System; University of Michigan; University of Michigan System; University of Michigan
  摘要：Problem definition: We address two key questions faced by patients, physicians, and policy makers: (1) How do different types of patients benefit differently from elite surgeons? and (2) How can outcome data be used to achieve better healthcare at both the individual and social levels? Academic/practical relevance: Existing healthcare provider quality information, which is almost exclusively based on population averages, cannot detect differences in the surgeon effect for patients with differe...
• Are Hazardous Substance Rankings Effective? An Empirical Investigation of Information Dissemination About the Relative Hazards of Chemicals and Emissions Reductions AI翻译
  作者：Fu, Wayne; Kalkanci, Basak; Subramanian, Ravi
  作者单位：University of Michigan System; University of Michigan; University System of Georgia; Georgia Institute of Technology
  摘要：Problem definition: Whether information dissemination about chemical hazards drives managers at facilities to undertake corresponding environmental actions, remains an open question that has not been adequately examined in the literature. Academic/practical relevance: We fill this gap in the literature by empirically investigating reductions in chemical emissions by facilities in relation to changes in the assessed hazard levels of chemicals evidenced in periodically-updated public information...
• The Role of Store Brand Spillover in a Retailer's Category Management Strategy AI翻译
  作者：Alan, Yasin; Kurtulus, Mumin; Wang, Chunlin
  作者单位：Vanderbilt University
  摘要：Problem definition: We study a retailer's category management strategy and interactions with its supply chain partners in a setting in which increasing the store brand (SB) market share in a focal category improves the retailer's overall profitability by creating demand spillover to other categories. Academic/practical relevance: Unlike most category management research, which focuses on category profit maximization, our research incorporates SB spillover observed in practice into the retailer...
• R&D Spending: Dynamic or Persistent? AI翻译
  作者：Pennetier, Christophe; Girotra, Karan; Mihm, Jurgen
  作者单位：INSEAD Business School; Cornell University; INSEAD Business School
  摘要：Problem definition: Should the management of research and development (R&D) be persistent in its approach to funding R&D or rather allow for quick reaction and dynamism? Academic/practical relevance: Under a persistent policy, allocations remain nearly constant irrespective of circumstances; under a dynamic policy, R&D spending increases (respectively, declines) when opportunities arise (respectively, fail to materialize). Practitioners give conflicting answers as to which policy is preferable...
• Task Interdependence and Firm Performance in Outsourced Service Operations AI翻译
  作者：Ramasubbu, Narayan; Shang, Jennifer; May, Jerrold H.; Tjader, Youxu; Vargas, Luis
  作者单位：Pennsylvania Commonwealth System of Higher Education (PCSHE); University of Pittsburgh
  摘要：We conceptualize task interdependence between firms in outsourced service operations as an endogenous design choice made by the outsourcing firm. Then, utilizing relative firm efficiency and Tobin's q as performance metrics, we examine the impacts of the task interdependence choices of outsourcing firms on their performances. We examine data, collected from a variety of sources, on 184 service alliances across nine industries. We find that task interdependence in outsourced service operations ...
