• Determinants of country-level investment in information technology AI翻译

  摘要：Investment in information technology (IT) is an important driver of economic growth and productivity in the United States and other developed countries, but as yet it is not shown to be a significant driver in developing countries. Previous research suggests that IT investment and complementary assets are insufficient for developing countries to realize economic benefits. This research note examines the factors that influence IT investment in developed and developing countries to determine how...
• Cooperative planning, uncertainty, and managerial control in concurrent design AI翻译

  摘要：W e examine whether cooperative planning and uncertainty affect the magnitude of rework in concurrent engineering projects with upstream and downstream operations, and explore the impact of such rework on project delays. Using survey data from a sample of 120 business process (BP) redesign and related information technology (IT) development projects in healthcare and telecommunications, our results indicate that upstream (BP) rework and downstream (IT) rework is mediated and mitigated by coope...
• Pricing and capacity rationing for rentals with uncertain durations AI翻译
  作者：Gans, Noah; Savin, Sergei

  摘要：We consider a rental firm with two types of customers. Contract customers pay fixed, prenegotiated rental fees and expect a high quality of service. Walk-in customers have no contractual relations with the firm and are shopping for price. Given multiple contract and walk-in classes, the rental firm has to decide when to offer service to contract customers and what fees to charge walk-in customers for service. We formulate this rental management problem as a problem in stochastic control and ch...
• Obtaining fast service in a queueing system via performance-based allocation of demand AI翻译
  作者：Cachon, Gerard P.; Zhang, Fuqiang

  摘要：Any buyer that depends on suppliers for the delivery of a service or the production of a make-to-order component should pay close attention to the suppliers' service or delivery lead times. This paper studies a queueing model in which two strategic servers choose their capacities/processing rates and faster service is costly. The buyer allocates demand to the servers based on their performance; the faster a server works, the more demand the server is allocated. The buyer's objective is to mini...
• A spatiotemporal analysis of the global diffusion of ISO 9000 and ISO 14000 certification AI翻译

  摘要：We study the global diffusion of ISO 9000 and ISO 14000 certification using a network diffusion framework. We start by investigating the presence and nature of contagion effects by defining alternative cross-country networks and testing their relative strength. Second, we study how the rate of diffusion differs between the two standards and between early- and later-adopting countries. Third, we identify which countries had more influence on diffusion than others. Empirically, we build a diffus...
• Resolving inconsistencies in utility measurement under risk:: Tests of generalizations of expected utility AI翻译

  摘要：This paper explores inconsistencies that occur in utility measurement under risk when expected utility theory is assumed and the contribution that prospect theory and some other generalizations of expected utility can make to the resolution of these inconsistencies. We used five methods to measure utilities under risk and found clear violations of expected utility. Of the theories studied, prospect theory was the most consistent with our data. The main improvement of prospect theory over expec...
• Pushing quality improvement along supply chains AI翻译
  作者：Zhu, Kaijie; Zhang, Rachel Q.; Tsung, Fugee
  作者单位：Hong Kong University of Science & Technology
  摘要：In this paper, we consider a buyer who designs a product and owns the brand, yet outsources the production to a supplier. Both the buyer and the supplier incur quality-related costs, e.g., costs of customer goodwill and future market share loss by the buyer and warranty-related costs shared by both the buyer and the supplier whenever a nonconforming item is sold to a customer. Therefore, both parties have an incentive to invest in quality-improvement efforts. This paper explores the roles of d...
• Method and psychological effects on learning behaviors and knowledge creation in quality improvement projects AI翻译
  作者：Choo, Adrian S.; Linderman, Kevin W.; Schroeder, Roger G.
  作者单位：Rensselaer Polytechnic Institute; University of Minnesota System; University of Minnesota Twin Cities
  摘要：This study investigates two mechanisms of knowledge creation-one that is method driven and the other that is psychologically driven. Results show that the two mechanisms have different effects on the learning behaviors and knowledge created in Six Sigma projects. The method mechanism directly influences learning behaviors, while the psychological mechanism directly affects knowledge creation. The effects of both mechanisms on knowledge creation are complementary, yet independent. Findings sugg...
