  摘要：Problem definition: Because of the emergence and development of e-commerce, customers demand faster and cheaper delivery services. However, many retailers find it challenging to efficiently provide fast and on-time delivery services to their customers. Academic/practical relevance: Amazon and Walmart are among the retailers that are relying on independent crowd drivers to cope with on-demand delivery expectations. Methodology: We propose a novel robust crowdsourcing optimization model to study...
• Technology Licensing and Productivity Growth: Evidence from Manufacturing Firms in Developing Economies AI翻译

  摘要：Problem Definition: This study examines whether and how the relationship between technology licensing and productivity growth in the short run is affected by the challenges and constraints inherent in the contexts in which developing economy firms operate. We do so by investigating the moderating role of formal workforce training program in a firm and the corruption level and the infrastructural constraint level in the firm's external environment. Academic/Practical Relevance: Although the ado...
• Taxing the Taxpayers: An Empirical Investigation of the Drivers of Baseline Changes in US Federal Government Technology Programs AI翻译

  摘要：Problem definition: The U.S. federal government makes significant investments in technology programs to deliver essential services to the public. The execution of a program is monitored against a baseline-an aggregate plan representing the program's planned budget, schedule and scope. Recent reports suggest that federal technology programs are re-baselined multiple times, resulting in additional spending of taxpayer money. Although a program's scope has often been considered a driver of baseli...
• Labor Welfare in On-Demand Service Platforms AI翻译

  摘要：Problem definition: An on-demand service platform relies on independent workers (agents) who decide how much time, if any, to devote to the platform. Some labor advocates have argued that an expansion of the labor pool hurts agents-by reducing the wage and agent utilization (i.e., the fraction of time an agent is busy serving customers). Motivated by concern for agent welfare, regulators are considering measures that reduce the labor pool size or that impose a floor on the nominal wage or effe...
• Data Set: 187 Weeks of Customer Forecasts and Orders for Microprocessors from Intel Corporation AI翻译
  作者：Manary, Matthew P.; Willems, Sean P.
  作者单位：Intel Corporation; Intel USA; University of Tennessee System; University of Tennessee Knoxville
  摘要：Problem definition: This data set contains 187 consecutive weeks of Intel microprocessor demand information for all five distribution centers in one of its five sales geographies. For every stock keeping unit (SKU) at every location, the weekly forecasted demand and actual customer orders are provided as well as the SKU's average selling price category. These data are provided by week and by distribution center, producing 26,114 records in total. Academic/practical relevance: The 86 SKUs in th...
• Adaptive Learning of Drug Quality and Optimization of Patient Recruitment for Clinical Trials with Dropouts AI翻译
  作者：Tian, Zhili; Han, Weidong; Powell, Warren B.
  作者单位：Coastal Carolina University; Princeton University
  摘要：Problem definition: Clinical trials are crucial to new drug development. This study investigates optimal patient enrollment in clinical trials with interim analyses, which are analyses of treatment responses from patients at intermediate points. Our model considers uncertainties in patient enrollment and drug treatment effectiveness. We consider the benefits of completing a trial early and the cost of accelerating a trial by maximizing the net present value of drug cumulative profit. Academic/...
• Flexible Drug Approval Policies AI翻译
  作者：Bravo, Fernanda; Corcoran, Taylor C.; Long, Elisa F.
  作者单位：University of California System; University of California Los Angeles
  摘要：Problem definition: To approve a novel drug therapy, the U.S. Food and Drug Administration (FDA) requires clinical trial evidence demonstrating efficacy with 2.5% statistical significance, although the agency often uses regulatory discretion when inter-preting these standards. Factors including disease severity, prevalence, and availability of existing therapies are qualitatively considered; yet, current guidelines fail to systematically consider such characteristics in approval decisions. Aca...
• Recovering Global Supply Chains from Sourcing Interruptions: The Role of Sourcing Strategy AI翻译
  作者：Jain, Nitish; Girotra, Karan; Netessine, Serguei
  作者单位：University of London; London Business School; University of Pennsylvania
  摘要：Problem definition: Fast recovery from sourcing interruptions is a key objective for global supply chains and for business continuity professionals. In this paper, we study the impact of different supply chain strategies-supplier diversification and the use of long-term relationships-on the ability of a supply chain to recover from sourcing interruptions. Academic/practical relevance: Improving supply chains' recovery ability has been an important focus area for both practitioners and academic...
• Extended Producer Responsibility for Pharmaceuticals AI翻译
  作者：Alev, Isil; Atasu, Atalay; Toktay, L. Beril; Zhang, Can
  作者单位：Boston College; INSEAD Business School; University System of Georgia; Georgia Institute of Technology; Duke University
  摘要：Problem definition: We investigate the effectiveness of different extended producer responsibility (EPR) implementation models for pharmaceuticals. In particular, we study two viable and prevalent models: (1) source reduction (SR), where a form of fee on sale is imposed on producers, and (2) end-of-pipe control (EC), where producers are made responsible for the collection of unused pharmaceuticals. Academic/practical relevance: The existing literature on EPR implementation models has focused p...
• Optimal Contract Under Asymmetric Information About Fairness AI翻译
  作者：Pavlov, Valery; Katok, Elena; Zhang, Wen
  作者单位：University of Auckland; University of Texas System; University of Texas Dallas; Baylor University
  摘要：Problem definition: To improve the poor performance of supply chains caused by misaligned incentives under the wholesale price contract, theory proposes coordinating contracts. However, a common finding of experimental studies testing such contracts is that they tend to yield only a marginal, if any, performance improvement over wholesale pricing. These studies identify several behavioral factors that are at play but none accounted for by the theory proposing coordinating contracts. Among them...
