Revenue implication of auction value in <Emphasis Type="Italic">k</Emphasis>-price sealed-bid auctions: An experimental study

In this paper, we show that in a heterogeneous bidding community with predominantly risk-seeking bidders, third-price sealed-bid auctions yield higher revenue for the seller than first-price sealed-bid auctions when the auction value is low. Conversely, when the value of the auction is high, first-price sealed-bid auctions yield higher revenue for the seller than third-price sealed-bid auctions. Existing theoretical findings for a homogeneous group of risk-seeking individuals imply that third-price sealed-bid auctions should generate higher revenues for the seller than first-price sealed-bid auctions. Our results for low-value auctions agree but our results for high-value auctions do not agree with the existing findings. We discuss the implications of this discrepancy as a function of the shift in goal orientation from a win-focus to a value-focus as the value of the auction increases.

供应链系统协调机制研究

供应链是典型的需要协调的系统。供应链系统的协调机制是在供应链系统内成员之间建立战略性合作伙伴的关系,提高信息共享程度、降低成本、实现系统利润最大化。为了实现良好的供应链协调效果,应建立稳定而有效的协调机制,使设计出的协调机制在供应联系统中顺利实现。     

无源超高频抗金属标签天线设计方法综述

射频识别（RFID）技术的不断发展,对标签天线提出了更高的要求。普通标签天线直接应用于金属表面时,由于受到金属边界的影响,其性能会出现一定程度的下降。详细介绍了4种无源超高频抗金属标签天线的设计方法,包括调整天线与金属面的间距、采用吸波材料、引入高阻抗表面基板、采用平面倒F天线（PIFA）或微带天线结构,并分析了每种方法的优缺点及其对标签天线的阻抗匹配、带宽、尺寸、识别距离以及成本等方面的影响。微带贴片天线不仅具有低剖面、高方向性等优点,而且含有金属接地板,常用作抗金属标签天线的设计原型。在抗金属标签天线的设计与实际应用中,研究者可针对具体要求灵活运用这些设计方法。     

The different roles of product originality and usefulness in generating word-of-mouth

This paper explores how the dimensions of new products, specifically, the originality and usefulness of the products, influence word-of-mouth (WOM). In four studies, using lab and field setups, we find that originality and usefulness have different effects on WOM. We show that consumers spread more WOM about original products, but the valence of what they say depends on the usefulness of the product. Therefore, originality enhances the effect of usefulness such that consumers spread relatively more and more positively valenced WOM about original and useful products compared to less original but equally useful products. Conversely, consumers spread more and more negatively valenced WOM about original products that are not useful compared to less original products with the same level of low usefulness. The results indicate that product originality should be managed carefully when developing and positioning new products. Although originality increases buzz, it might lead to negatively valenced WOM when the usefulness of the product is perceived to be low.     

非对称信息下的电力产业需求侧管理机制设计

应用机制设计理论的一般方法,对需求侧管理合约进行分析,认为传统的峰值定价不能有效的解决信息不对称的问题,偏离了需求侧管理的目标。激励性需求侧管理可以根据消费者的类型,提供不同的合约,从而有效地解决信息不对称条件下社会福利偏离的问题。这种合约在一定的范围内解决电子资源供给与需求的矛盾,符合需求侧管理的目标,实现市场环境下电力资源的最优配置。     

Modeling Methods for Discrete Choice Analysis

This paper introduces new forms, sampling and estimation approaches fordiscrete choice models. The new models include behavioral specifications oflatent class choice models, multinomial probit, hybrid logit, andnon-parametric methods. Recent contributions also include new specializedchoice based sample designs that permit greater efficiency in datacollection. Finally, the paper describes recent developments in the use ofsimulation methods for model estimation. These developments are designed toallow the applications of discrete choice models to a wider variety ofdiscrete choice problems.
