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...

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...

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.

摘要：This paper integrates and extends the literatures on industry evolution and dominant firms to develop a dynamic theory of dominant and fringe competitive interaction in a segmented industry. It argues that a dominant firm, seeing contraction of growth in its current segment(s), enters new segments in which it can exploit its technological strengths, but that are sufficiently distant to avoid cannibalization. The dominant firm acts as a low-cost Stackelberg leader, driving down prices and trigg...

摘要：Geographically dispersed sellers in electronic reverse marketplaces such as those hosted by market-makers like Ariba are uncertain about the number of competitors they face in any given market session. We refer to this uncertainty about the number of competitors as market-structure uncertainty. Over the course of several market sessions sellers learn about the competitive nature of the marketplace. How they learn to reduce the market-structure uncertainty depends on the market-transparency sch...

摘要：In this paper, we model the formation of innovation networks as they emerge from bilateral decisions. In contrast to much of the literature, here firms only consider knowledge production, and not network issues, when deciding on partners. Thus, we focus attention on the effects of the knowledge and information regime on network formation. The effectiveness of a bilateral collaboration is determined by cognitive, relational, and structural embeddedness. Innovation results from the recombination...

摘要：We integrate psychological theories of individual creativity with organizational theories of exploration versus exploitation to examine the relationship between past success and creativity over time. A key prediction derived from this theoretical integration is that successful people should be more likely to generate new ideas, but these ideas will tend to be less divergent as they favor the exploitation of familiar knowledge at the expense of the exploration of new domains. This prediction de...

摘要：Decisions under risk are often multidimensional, where the preferences of the decision maker depend on example, an individual might be concerned about both her level of wealth and the condition of her health. Many times the signs of successive cross-derivatives of a utility function play an important role in these models. However, there has not been a simple and intuitive interpretation for the meaning of such derivatives. The purpose of this paper is to give such an interpretation. In particu...

摘要：Selection procedures are used in a variety of applications to select the best of a finite set of alternatives. ''Best'' is defined with respect to the largest mean, but the mean is inferred with statistical sampling, as in simulation optimization. There are a wide variety of procedures, which begs the question of which selection procedure to select. The main contribution of this paper is to identify, through extensive experimentation, the most effective selection procedures when samples are in...

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...
