History-based price discrimination and entry in markets with switching costs: A welfare analysis

We analyze history-based price discrimination in an asymmetric industry, where an incumbent, protected by switching costs, faces an entrant who does not have access to information about consumers’ purchase histories. We demonstrate that consumer surplus is higher with uniform pricing than with history-based price discrimination. We find that the entry decision is invariant to whether the incumbent implements history-based pricing or uniform pricing. This implies that the potential abuse of market dominance imposed by history-based price discrimination is exploitation, not exclusion. Finally, we establish that the profit gain to the incumbent from history-based pricing exceeds the associated loss to consumers.     

金融市场不完全的理论分解与测度研究——基于中国封闭式基金折价的动态考察

基于金融市场不完全的结构分解,文章构建了一个涵盖市场交易费用、套利定价机制不完备程度和行为金融学因素的封闭式基金折价机理模型,分阶段计量分析发现:(1)普通交易成本因素影响基金折价约6.1%;(2)2007年前股指期货缺位因素导致基金折价约25.6%,之后随着股指期货的正式推出该影响显著下降;(3)市场套利定价机制不完备程度测度表明,该因素影响基金平均折价三个阶段分别为8.26%、5.87%和7.91%;(4)时期固定效应表明,有5个季度因投资者情绪相对乐观而降低了基金的平均折价率。     

封闭式基金折价均值回归研究——基于协整分析

以我国仍在交易的25支封闭式基金为研究对象,利用每支基金从上市第2年到2010年12月的交易价格和净值的周数据进行实证分析。运用恩格尔-格兰杰两步法并进行Johansen协整检验,证实了我国封闭式基金折价存在均值回归现象。同时,误差修正模型分析结果显示,25支样本基金中有22支基金的交易价格与净值的误差修正项显著,说明封闭式基金的交易价格和净值的变动均会影响基金折价,其中交易价格变动对折价的影响更大。最后,提出我国基金投资者可通过投资折价较大的封闭式基金获得超额收益。     

I Have Paid Less Than You! The Emotional and Behavioral Consequences of Advantaged Price Inequality

This study examines the emotion blends and the subsequent customer reactions that occur in advantaged price inequality situations, that is, when consumers learn that retailers charged them a lower price than what the same retailers charged another customer. Drawing on the appraisal theories of emotion and on social comparison theory, an experiment (n = 272) and a field study (n = 261) are conducted. The results reveal that in advantaged price inequality situations, customers experience a host of positive and negative emotions depending on two factors: the quality of relationship that the customer has with a disadvantaged other customer (neutral, positive, or negative) and the attribution of agency for the price advantage (situational attribution to competition, external attribution to store policies, or internal attribution to customer abilities). Positive emotions include happiness, gratitude, pride, and malicious joy; while negative emotions include pity, outrage, and guilt. These emotions are shown to mediate the occurrence of customer reactions (i.e., customer satisfaction, loyalty, WOM referral, and WOM activity). The article concludes with theoretical implications and recommendations for retail practitioners on how to use dynamic pricing.     

法律判决经济价值效应的金融学分析

法律判决不仅体现了法律对当事人在事件中关系的判断与处置,也会由此产生对当事人乃至全社会的经济价值效应。对于前者,判决体现的是法律的判断;对于后者,传统理论普遍认为是一个零和游戏。然而,从金融学的资产定价理论出发,却发现法律判决的社会经济价值效应并非零和,而且这些价值不仅影响了社会经济活动的行为判断,还对某些资产定价的传统理论提出了挑战。     

中国原油定价机制转型——基于SD模型分析

本文基于可持续发展视角,运用系统动力学方法构建中国原油定价机制改革模型。通过模型系统模拟,分析认为,原油定价改革涉及各主要因素动态变化,以及经济增长、原油需求、原油已探明储量和原油价格诸多关键因素相互影响,在此基础上又对中国原油定价机制改革所做出的政策选择以及制度变化进行了分析。     

对价方式、盈余管理与市场绩效

选取国有企业控制权转移的样本,剖析有偿转让和无偿转让这两种不同对价方式对盈余管理的影响,并对不同的对价方式下控制权转移是否改进了企业的中短期及长期的市场绩效进行经验检验。研究发现：（1）有偿转让控制权的对价方式更易推动上市公司通过操控应计利润调低净资产,提高溢价率,以符合政策要求;（2）在整体上无偿类样本相对于同行业公...     

中国电信业接入定价与互联互通分析

中国电信业的互联互通问题日益凸显,作为其核心内容的接入定价问题越来越受到规制学家的关注。论文介绍了当前几种主流接入定价方法,通过分析各种方法的优缺点,结合当前中国电信业的基本状况及现实特点,从理论上得出中国电信业应采用以成本为基础的网间互联接入定价方式,为三大运营商更好地实现有效竞争,实现真正意义上的互联互通提供了理论依据。     

中国开展“以房养老”影响因素的实证分析

“以房养老”对解决我国面临的养老金支付有重要的意义。但是在实践中,我国老年群体参与的积极性并不高,本文在社会调查的基础上,进行了数据整理并且使用Logit模型进行了实证研究,得出影响中国老年群体参与其中的关键因素是传统习惯影响的结论,并且就此提出解决问题的设想。
