摘要：In this work we introduce a class of measures for evaluating the quality of financial positions based on their ability to achieve desired financial goals. In the spirit of Simon (Simon, H. A. 1959. Theories of decision-making in economics and behavioral science. Amer. Econom. Rev. 49(3) 253-283), we call these measures satisficing measures and show that they are dual to classes of risk measures. This approach has the advantage that aspiration levels, either competing benchmarks or fixed target...

摘要：We investigate how dynamic resource substitution in service systems impacts capacity requirements and responsiveness. Inspired by the contrasting network strategies of FedEx and United Parcel Service (UPS), we study when two service classes (e. g., express or regular) should be served by dedicated resources (e. g., air or ground) or by an integrated network (e. g., air also serves regular). Using call center terminology, the question is whether to operate two independent queues or one N-networ...

摘要：We provide large sample evidence that past price extremes influence investors' trading decisions. Volume is strikingly higher, in both economic and statistical terms, when the stock price crosses either the upper or lower limit of its past trading range. This increase in volume is more pronounced the longer the time since the stock price last achieved the price extreme, the smaller the firm, the higher the individual investor interest in the stock, and the greater the ambiguity regarding valua...

摘要：In this paper, we introduce robust versions of the classical static and dynamic single-leg seat allocation models. These robust models take into account the inaccurate estimates of the underlying probability distributions. As observed by simulation experiments, it turns out that for these robust versions the variability compared to their classical counterparts is considerably reduced with a negligible decrease in average revenue.

摘要：Our paper shows that the parameters in existing theoretical models of channel substitution such as offline transportation cost, online disutility cost, and the prices of online and offline retailers interact to determine consumer choice of channels. In this way, our results provide empirical support for many such models. In particular, we empirically examine the trade-off between the benefits of buying online and the benefits of buying in a local retail store. How does a consumer's physical lo...

摘要：Good metrics are well-defined formulae (often involving averaging) that transmute multiple measures of raw numerical performance (e. g., dollar sales, referrals, number of customers) to create informative summary statistics (e. g., average share of wallet, average customer tenure). Despite myriad uses (benchmarking, monitoring, allocating resources, diagnosing problems, explanatory variables), most uses require metrics that contain information summarizing multiple observations. On this criteri...

摘要：We analyze the allocation of objects in a network of caches that collaborate to service requests from customers. A thorough analysis of this problem in centralized and decentralized setups, both of which occur in practice, is essential for understanding the benefits of collaboration. A key insight offered by this paper is that an efficient implementation of cooperative cache management is possible because, in the centralized scenario, the object allocation resulting in the best social welfare ...
