• Balancing search and stability: Interdependencies among elements of organizational design AI翻译
  作者：Rivkin, JW; Siggelkow, N

  摘要：We examine how and why elements of organizational design depend on one another. An agent-based simulation allows us to model three design elements and two contextual variables that have rarely been analyzed jointly: a vertical hierarchy that reviews proposals from subordinates, an incentive system that rewards subordinates for departmental or firm-wide performance, the decomposition of an organization's many decisions into departments, the underlying pattern of interactions among decisions, an...
• Individual centrality and performance in virtual R&D groups: An empirical study AI翻译

  摘要：Communication technologies support virtual R&D groups by enabling immediate and frequent interaction of their geographically-distributed members. Performance of members in such groups has yet to be studied longitudinally. A model proposes not only direct effects of. functional role, status, and communication role on individual performance, but also indirect effects through individual centrality. Social network analysis was performed on e-mail samples from two time periods separated by four yea...
• Is subsidizing inefficient bidders actually costly? AI翻译

  摘要：A widespread practice, particularly in public-sector procurement and dispersal, is to subsidize a class of competitors believed to be at an economic disadvantage. Arguments for such policies vary, but they typically assume that benefits of subsidization must be large enough to outweigh a presumed economic cost of the subsidy. When disadvantaged competitors compete in auctions, the subsidy serves to. make them more competitive rivals. Other bidders rationally respond by bidding more aggressivel...
• Learning by doing something else: Variation, relatedness, and the learning curve AI翻译
  作者：Schilling, MA; Vidal, P; Ployhart, RE; Marangoni, A

  摘要：Many organizational learning studies have an implicit assumption that the learning rate is maximized through specialization: the more an individual or organization focuses on a particular task, the faster it will improve. However, through contrasting the various learning process theories described in the research on organizational, group, and individual learning, we develop a set of competing hypotheses that suggest some degree of variation might improve the learning rate. Furthermore, such co...
• Relational embeddedness and learning: The case of bank loan managers and their clients AI翻译
  作者：Uzzi, B; Lancaster, R

  摘要：As a complement to the literature on learning in firms, we investigate learning in markets, a nascent area of study that focuses on how learning occurs between, rather than within, firms. The core idea behind our framework is that networks shape knowledge transfer and learning processes by creating channels for knowledge trade and reducing the risk of learning. In developing our framework, we elaborate on the knowledge transfer capabilities of different types of social ties, the informational ...
• Interruptive events and team knowledge acquisition AI翻译

  摘要：Interruptions have commonly been viewed as negative and as something for managers to control or limit. In this paper, I explore the relationship between interruptions and acquisition of routines-a form of knowledge-by teams. Recent research suggests that interruptions may play an important role in changing organizational routines, and as such may influence knowledge transfer activities. Results suggest that interruptions influence knowledge transfer effort, and both knowledge transfer effort a...
• Managerial insights into the effects of interactions on replacing members of a team AI翻译
  作者：Solow, D; Vairaktarakis, G; Piderit, SK; Tsai, MC

  摘要：A mathematical model is presented for studying the effects of interactions among team members on the process of replacing members of a team in an organization. The model provides the ability to control the number of members that interact with each individual on the team. Through the use of analysis and computer simulations, it is shown how the amount of interaction affects the tradeoff between the expected performance and the number of replacements and interviews needed to find a good team usi...
• Effective zero-inventory-ordering policies for the single-warehouse multiretailer problem with piecewise linear cost structures AI翻译

  摘要：We analyze the problem faced by companies that rely on TL (Truckload) and LTL (Less than Truckload) carriers for the distribution of products across their supply chain. Our goal is to design simple inventory policies and transportation strategies to satisfy time-varying demands over a finite horizon, while minimizing systemwide cost by taking advantage of quantity discounts in the transportation cost structures. For this purpose, we study the cost effectiveness of restricting the inventory pol...
• Hospital operating room capacity expansion AI翻译
  作者：Lovejoy, WS; Li, Y

  摘要：A large midwestern hospital is expecting an increase in, surgical caseload: New operating, room (OR) capacity can be had by building new ORs or extending the working hours in the current ORs. The choice among these options is complicated by the fact that patients; surgeons and, surgical staff, and hospital administrators are all important stakeholders in: the health service operation, and each has different priorities. This. paper investigates the trade-offs among three performance criteria (w...
• Information sharing in a supply chain with horizontal competition AI翻译
  作者：Li, LD
  作者单位：Yale University
  摘要：This paper examines the incentives for firms to share information vertically in a two-level supply chain in which there are an upstream firm (a manufacturer) and many downstream firms (retailers). The retailers are engaged in a Cournot competition and are endowed with some private information. Vertical information sharing has two effects: direct effect due to the changes in strategy by the parties involved in sharing the information and indirect effect (or leakage effect) due to the changes in...
