摘要：Reducing congestion is a primary concern in the design and analysis of queueing networks, especially in systems where sources of randomness are characterized by high variability. This paper considers a multiserver first-come, first-served (FCFS) queueing model where we arrange servers in two stations in series. All arrivals join the first service center, where they receive a maximum of T units of service. Arrivals with service requirements that exceed the threshold T join the second queue, whe...

摘要：Our study examines the imitation behavior of UK automobile manufacturers from 1894 to 1981 and supports previous studies on interorganizational imitation by showing that manufacturers tend to imitate other manufacturers that are similar. We also find that the degree of confidence manufacturers have in their imitating behavior affects the intensity of that behavior, where an organization's confidence is determined by the variance of the routines used by its reference group and the number of fir...

摘要：Internet technology has allowed for a higher degree of decoupling between the information-intensive sales process and the physical process of inventory management than its brick-and-mortar counterpart. As a result, some Internet retailers choose to outsource inventory and back-end operations to focus on the sales/marketing aspects of e-commerce. Nonetheless, many retailers keep fulfillment capabilities in-house. In this paper, we identify and empirically test factors that persuade firms to int...

摘要：Machine learning methods are powerful tools for data mining with large noisy databases and give researchers the opportunity to gain new insights into consumer behavior and to improve the performance of marketing operations. To model consumer responses to direct marketing, this study proposes Bayesian networks learned by evolutionary programming. Using a large direct marketing data set, we tested the endogeneity bias in the recency, frequency, monetary value (RFM) variables using the control fu...

摘要：Downside loss-averse preferences have seen a resurgence in the portfolio management literature. This is due to the increasing use of derivatives in managing equity portfolios and the increased use of quantitative techniques for bond portfolio management. We employ the lower partial moment as a risk measure for downside loss aversion and compare mean-variance (M-V) and mean-lower partial moment (M-LPM) optimal portfolios under nonnormal asset return distributions. When asset returns are nearly ...

摘要：We propose the optimal strategies in the end-product market for manufacturers of proprietary component brands' MPCBs for short. MPCBs can pursue one of three end-product roles: sole entrant, as with 3Com that, until recently, offered its Palm operating system only as part of its own Palm handheld devices; co-optor, as with Canon, whose specialty motors go into its own and HP laser printers; component supplier, as with Intel, which has refrained from making its own PCs. Applying extant theoreti...

摘要：Making effective decisions under risk often requires making accurate predictions of other people's decisions under risk. We experimentally assess the accuracy of people's predictions of others' risky choices. In four studies, we find evidence of systematic inaccuracy: predictions of others' choices are too regressive. That is, people predict that others' choices will be closer to risk neutrality than those choices actually are. Where people are risk seeking, they predict that others will be ri...

摘要：This paper provides evidence that analysts who have predicted earnings more accurately than the median analyst in the previous four quarters tend to be simultaneously less accurate and further from the consensus forecast in their subsequent earnings prediction. This phenomenon is economically and statistically meaningful. The results are robust to different estimation techniques and different control variables. Our findings are consistent with an attribution bias that leads analysts who have e...

摘要：One of the goals of procurement is to establish a competitive price while affording the buyer some flexibility in selecting the suppliers to deal with. Reverse auctions do not have this flexibility, because it is the auction rules and not the buyer that determines the winner. In practice, however, hybrid mechanisms that remove some suppliers and a corresponding amount of demand from the auction market are quite common. We find that in theory such hybrid mechanisms increase competition and make...
