  摘要：The procurement of maintenance, repair, and operating (MRO) goods has remained a relatively understudied topic in the literature. Though vital cost efficiencies can be extracted from procurement processes through investments in e-procurement systems, there is little empirical work that addresses how such systems should be deployed within organizations. In this study, we focus on the role of e-procurement systems in MRO procurement and study two critical aspects of infusion. The first dimension...

  摘要：This study is motivated by examples of outsourcing that are not readily explained by widely established economic theories. We extend recent literature that develops the idea that outsourcing can help firms avoid overinvestment by specifying more precisely the conditions under which this thesis is likely to apply. Our extension is realized through a two-period game theoretic model in which the outsourcing and in-house investments are driven by (1) the cost required to develop a product or proce...
• Does a Store Brand Always Hurt the Manufacturer of a Competing National Brand? AI翻译

  摘要：It is generally believed that store brands hurt the manufacturers of competing national brands while benefiting retailers. In this study, we challenge this notion by studying the impacts of a store brand when it is introduced by a power retailer. We show that a store brand may benefit the manufacturer when the interaction between the manufacturer and retailer is modeled as a retailer-led Stackelberg game. This phenomenon occurs because the store brand changes the nature of the strategic intera...
• Strategic Consumer Cooperation in a Name-Your-Own-Price Channel AI翻译

  摘要：Supplier reluctance to openly advertise highly discounted products on the Internet has stimulated development of opaque name-your-own-price sales channels. Unfortunately (for suppliers), there is significant potential for online consumers to exploit these channels through collaboration in social networks. In this paper, we study three possible forms of consumer collaboration: exchange of bid result information, coordinated bidding, and coordinated bidding with risk pooling. We propose an egali...
• Note on The Backroom Effect in Retail Operations AI翻译

  摘要：Eroglu et al. (2013) study a retailer with limited shelf capacity and a backroom. They study a continuous review (r, q) ordering policy with a known order quantity, q. Assuming that backorders can be satisfied from the backroom inventory (if available), they find the expression for the optimal reorder level, r. Our work builds on Eroglu et al. (2013). We correct an erroneous derivation of the expected overflow term, as well as derive an exact expression for the expected cost function, and henc...
• Long-Term Contracting: The Role of Private Information in Dynamic Supply Risk Management AI翻译

  摘要：We examine the critical role of evolving private information in managing supply risk. The problem features a dyadic channel where a dominant buyer operates a multiperiod inventory system with lost sales and fixed cost. He replenishes from a supplier, whose private state of production is vulnerable to random shocks and evolves dynamically over time. We characterize the optimal inventory policy with a simple semi-stationary structure; it distorts order quantity for limiting information rent only...
• Supply Chain Design and Carbon Penalty: Monopoly vs. Monopolistic Competition AI翻译

  摘要：This paper studies whether imposing carbon costs changes the supply chain structure and social welfare. We explore the problem from a central policymaker's perspective who wants to maximize social welfare. We consider two stakeholders, retailers, and consumers, who optimize their own objectives (i.e., profits and net utility) and three competitive settings (i.e., monopoly, monopolistic competition with symmetric market share, and monopolistic competition with asymmetric market share). For the ...
• Storing Fresh Produce for Fast Retrieval in an Automated Compact Cross-Dock System AI翻译

  摘要：We study temporary storage of fresh produce in a cross-dock center. In order to minimize cooling cost, compact storage systems are used. A major disadvantage of these systems is that additional retrieval time is needed, caused by necessary reshuffles due to the improper storage sequence of unit loads. In practice therefore, a dedicated storage policy is used in which every storage lane in the system accommodates only one product. However, this policy does not use the planned arrival time infor...
• A Newsvendor Who Chooses Informational Effort AI翻译

  摘要：We study a newsvendor who can acquire the services of a forecaster, or, more generally, an information gatherer (IG) to improve his information about demand. When the IG's effort increases, does the average ex ante order quantity rise or fall? Do average ex post sales rise or fall? Improvements in information technology and in the services offered by forecasters provide motivation for the study of these questions. Much depends on our model of the IG and his efforts. We study an IG who sends a ...
