  摘要：In this study, we investigate how consumers derive value from having the option to use physical stores for their transactions in the DVD rental market. We analyze data from consumers who subscribed to an online-offline video rental service from a leading company that closed a large number of physical store locations during our study period. We quantify the extent to which offline store closures induced individuals to terminate their subscriptions with our focal company. We further examine how ...

  摘要：Sustainability and long-term prosperity are chronic challenges in the agriculture sector of many countries. To address such challenges, farmer cooperatives are formed as an innovative approach to improve the livelihoods of millions of farmers around the world. Inspired by real-life practice in the Kenya coffee industry, we study a class of stochastic and dynamic inventory models for storable agricultural products with random exogenous supply and price. For a variety of cost functions relevant ...

  摘要：In this study, we develop a novel theoretical model of how the relationship between the buyer's use of power and the service provider's opportunism is moderated by the provider's perceptions of dependence advantage. Analyzing a dyadic dataset of 109 professional service relationships, we find that the extent to which the buyer's use of mediated and non-mediated power aligns with the service provider's perceptions of relative dependence is germane to the power-opportunism relationship. The noti...

  摘要：Procurement auctions are widely used by governments and corporations to solicit bids for services and projects. Such auctions involve significant risk for the buyer, because the delivered quality is highly uncertain. We examine a multi-attribute procurement auction combined with a performance-based contract. In this setting, suppliers submit bids which include both price and promised quality. After the buyer awards the contract to the winning bidder with the highest score, the supplier exerts ...

  摘要：The increasing number of scandals about supplier violations of environmental and social regulations has put multinational companies' (MNCs) reputations at risk. Customers make MNCs accountable for such violations, regardless of whether the violations involve tier-one or lower-tier suppliers. To address this pressure, some MNCs require their tier-one suppliers to comply with their sustainability requirements and ask them to cascade such requirements to their (lower-tier) suppliers. This researc...

  摘要：We consider the capacity allocation problem for a retailer with multiple suppliers and multiple demand classes. The retailer offers one seasonal product and reserves capacity from multiple suppliers. Customers in different classes are charged with different selling prices for the same product. We analyze the optimal capacity allocation policies with the following three types of customers: (i) patient customers, (ii) impatient customers, and (iii) customers with limited patience. To empower our...

  摘要：Even with the rapid proliferation of applications (apps) running on smart handheld devices, achieving success in mobile platform ecosystems is challenging for developers because of the heavily crowded marketplaces and easy substitutability of apps. In this study, we draw inspiration from biological ecosystems research and from the operations management literatures on software production, product management, and digital platforms to empirically examine the sustainability of newly launched apps ...
• Shelf Space Selection to Control Product Expiration AI翻译
  作者：Akkas, Arzum
  作者单位：Boston University
  摘要：Product expiration is an important problem in the consumer-packaged-goods industry eroding profits and generating substantial waste. We propose that shelf space selection can be an operational lever to control expiration of perishable inventory. To this end, we first explain the conditions under which shelf space impacts expiration then develop a method to determine the appropriate level of shelf space which incorporates this impact. We formulate a shelf space selection problem for a single pr...
• Continuity of Care and Risk of Readmission: An Investigation into the Healthcare Journey of Heart Failure Patients AI翻译
  作者：Senot, Claire
  作者单位：Tulane University
  摘要：We investigate the association between continuity of care mechanisms and a patient's risk of readmission in the context of one chronic condition, heart failure. We define continuity of care as the level of consistency across patient care episodes. We dynamically measure continuity of individual referring provider; continuity of physical location, which links multiple individual providers; and continuity of Accountable Care Organization, which spans a variety of individual and institutional pro...
• Relating the Approximability of the Fixed Cost and Space Constrained Assortment Problems AI翻译
  作者：Feldman, Jacob; Paul, Alice
  作者单位：Washington University (WUSTL); Brown University
  摘要：We study the classic assortment optimization problem in which a retailer seeks the revenue maximizing set of products to offer to each arriving customer. This study relates two variants of this assortment problem: the space constrained assortment problem, in which the retailer has a limit on the total space of the offered assortment, and the fixed cost assortment problem, in which the retailer incurs a fixed cost for each offered product. In particular, we develop an approximation scheme for t...
