  摘要：This experiment tested two behavioral properties of risky decision making-gain-loss separability (GLS) and coalescing. Cumulative prospect theory (CPT) implies both properties, but the transfer of attention exchange (TAX) model violates both. Original prospect theory satisfies GLS but may or may not satisfy coalescing, depending on whether editing rules are assumed. A configural form of CPT proposed by Wu and Markle [Wu, G., A. B. Markle. 2004. An empirical test of gain-loss separability in pr...
• Service performance analysis and improvement for a ticket queue with balking customers AI翻译

  摘要：Queueing systems managed by ticket technology are widely used in service industries as well as government offices. Upon arriving at a ticket queue, each customer is issued a numbered ticket. The number currently being served is displayed. An arriving customer balks if the difference between his ticket number and the displayed number exceeds his patience level. We propose a Markov chain model of a ticket queue and develop effective evaluation tools. These tools can help management quantify the ...
• When do employees become entrepreneurs? AI翻译
  作者：Hellmann, Thomas

  摘要：This paper examines an economic theory of when employees become entrepreneurs. It jointly addresses the two fundamental questions of when employees generate innovations, and whether these innovations are developed as internal ventures or outside the firm. The model shows that if generating innovations distracts employees from their assigned tasks, firms may discourage innovation. Firms may reject profitable opportunities that fall outside of their core activities. If employees own the intellec...
• From story line to box office: A new approach for green-lighting movie scripts AI翻译
  作者：Eliashberg, Jehoshua; Hui, Sam K.; Zhang, Z. John
  作者单位：University of Pennsylvania
  摘要：Movie studios often have to choose among thousands of scripts to decide which ones to turn into movies. Despite the huge amount of money at stake, this process-known as green-lighting in the movie industry is largely a guesswork based on experts' experience and intuitions. In this paper, we propose a new approach to help studios evaluate scripts that will then lead to more profitable green-lighting decisions. Our approach combines screenwriting domain knowledge, natural-language processing tec...
• Implementing new practices: An empirical study of organizational learning in hospital intensive care units AI翻译
  作者：Tucker, Anita L.; Nembhard, Ingrid M.; Edmondson, Amy C.
  作者单位：University of Pennsylvania
  摘要：This paper contributes to research on organizational learning by investigating specific learning activities undertaken by improvement project teams in hospital intensive care units and proposing an integrative model to explain implementation success. Organizational learning is important in this context because medical knowledge changes constantly and hospital care units must learn new practices if they are to provide high-quality care. To develop a model of factors affecting improvement projec...
• Electronic B2B marketplaces with different ownership structures AI翻译

  摘要：This paper analyzes electronic marketplaces with different ownership structures: biased marketplaces and neutral marketplaces. Biased marketplaces can be either buyer-owned or supplier-owned, whereas neutral marketplaces are owned by independent third parties. We develop a single-period model, with fulfilled expectations equilibrium. The buyers experience positive network effects that are a function of the number of suppliers and the suppliers receive similar positive network effects depending...
• A contract and balancing mechanism for sharing capacity in a communication network (vol 53, pg 1029, 2007) AI翻译
  作者：Anderson, Edward; Kelly, Frank; Steinberg, Richard; Waters, Robert
  作者单位：University of New South Wales Sydney; University of Cambridge; University of Cambridge
  摘要：In a recent paper, the first three authors proposed a method for determining how much to charge users of a communication network when they share bandwidth, and studied the existence and form of Nash equilibria for players' choices of capacity. However, the proof of one of the propositions in that paper contained a flaw. In this note, we prove that the original proposition is true under an additional condition, and provide two examples to show that this condition is necessary.
• Performance bounds for flexible systems requiring setups AI翻译

  摘要：Many organizations use product variety as one possible strategy for increasing their competitiveness. They have installed flexible manufacturing systems because these systems offer a powerful means for accommodating production and assembly of a variety of products. However, increased product variety comes at a cost. For instance, if the resource requires to be set up each time it switches to operate on a new product, the resulting delays and costs could negate the intended benefits of increase...
