摘要：Previous research has examined whether price dispersion exists in theoretically highly efficient Internet markets. However, much of the previous work has been focused on industries with low cost and undifferentiated products. In this paper, we examine the presence of price dispersion and product differentiation using data on the airline ticket offerings of online travel agents (OTAs). We find that different OTAs offer tickets with substantially different prices and characteristics when given t...

摘要：Organ exchanges are expected to increase the utilization of living donors and to alleviate the critical shortage of organs for transplantation. The typical arrangement involves a direct exchange between two blood-type incompatible donor-candidate pairs. An alternate possibility is an indirect exchange between one such pair and the highest priority candidate on the regular waiting list for cadaveric organs. This paper focuses on the mix of direct and indirect exchanges that maximizes the expect...

摘要：This paper proposes a model of how coordinating mechanisms work, and tests it in the context of patient care. Consistent with organization design theory, the performance effects of boundary spanners and team meetings were mediated by relational coordination, a communication- and relationship-intensive form of coordination. Contrary to organization. design theory, however, the performance effects of routines were also mediated :by relational coordination. Rather than serving as a replacement fo...

摘要：Brownian motion and normal distribution have been widely used in the Black-Scholes option-pricing framework to model the return of assets. However, two puzzles emerge from many empirical investigations: the leptokurtic feature that the return distribution of assets may have a higher peak and two (asymmetric) heavier tails than those of the normal distribution, and an empirical phenomenon called volatility smile in option markets. To incorporate both of them and to strike a balance between real...

摘要：Systems composed of activity choices that interact in nonsimple ways can allow firms to create and sustain a competitive advantage. However, in complex systems, decision makers may not always have a precise understanding of the exact strength of the interaction between activities. Likewise, incentive and accounting systems may lead decision makers to ignore or misperceive interactions. This paper studies formally the consequences of misperceiving interaction effects between activity choices. O...

摘要：For multiobjective optimization problems, it is meaningful to compute a set of solutions covering all possible trade-offs between the different objectives. The multiobjective knapsack problem is a generalization of the classical knapsack problem in which each item has several profit values. For this problem, efficient algorithms for computing a provably good approximation to the set of all nondominated feasible solutions, the Pareto frontier, are studied. For the multiobjective one-dimensional...

摘要：W e present an integral equation approach for the valuation of American-style derivatives when the underlying asset price follows a general diffusion process and the interest rate is stochastic. Our contribution is fourfold. First, we show that the exercise region is determined by a single exercise boundary under very general conditions on the interest rate and the dividend yield. Second, based on this result, We derive a recursive integral equation for the exercise boundary and provide a para...

摘要：The small-office/home-office (SOHO) professionals comprise the fastest growing segment in the labor force today. Typically being a one-person business based at home, SOHO owners mostly rely on office information technology to single handedly run their entire operation. Despite the segment's ostensibly growing dependence and influence on the information technology (IT) industry, still very little is known about the dynamics between SOHO and IT products. With the purpose of addressing this void,...

摘要：We develop a rule-based contingency misfit model and related hypotheses to test empirically the Burton and Obel (1998) multicontingency model forstrategic organizational design: The model is a set of if-then misfit rules, in which misfits lead to a loss in performance; they are complements to the strategy and organizational contingency theory fit rules. Using data from 224 small- and medium-sized Danish firms, misfits are categorized, and; identified: Then, performance hypotheses, are develope...

摘要：Rising levels of advertising competition have made it increasingly difficult to attract and hold consumers' attention and to establish strong memory traces for the advertised brand. A common communication strategy to break through this competitive clutter is to increase ad originality However, ad originality may have detrimental effects when consumers pay more attention to the ad at the expense of the advertised brand. Moreover, the positive effects of originality may quickly wane when the ad ...
