Introduction to Repeated Games with Private Monitoring

We present a brief overview of recent developments in discounted repeated games with (imperfect) private monitoring. The literature explores the possibility of cooperation in a long-term relationship, where each agent receives imperfect private information about the opponents' actions. Although this class of games admits a wide range of applications such as collusion under secret price-cutting, exchange of goods with uncertain quality, and observation errors, it has fairly complex mathematical structure due to the lack of common information shared by players. This is in sharp contrast to the well-explored case of repeated games under public information (with the celebrated Folk Theorems), and until recently little had been known about the private monitoring case. However, rapid developments in the past few years have revealed the possibility of cooperation under private monitoring for some class of games.

经典金融经济学理论体系若干矛盾与重构思考

经典金融经济学理论体系存在风险概念界定不符合现实、理性人假设与不确定性选择存在逻辑冲突以及无套利均衡方法不能很好解释现实等矛盾和问题。本文通过分析认知机理和投资者行为,构建了一个初步的分析框架。

行为资产组合理论：理论基础、内容及对异象的解释

行为金融理论于20世纪80年代兴起，它通过将行为因素引入决策过程从而对传统的金融理论做出补充。谢夫林(Shefrin)和斯特曼(Statman)在现代资产组合理论的基础上提出了行为资产组合理论，该理论是行为金融的理论基础之一。行为资产组合理论的基础包括安全第一组合理论和安全、潜力和期望理论。内容分为单一账户资产组合理论和多重账户资产组合理论。行为资产组合理论能够对市场中的一些异象做出合理的解释。     

BS7799标准及其在中观信息系统审计中的运用

在分析中观信息系统风险与损失的成因基础上,借鉴BS7799标准,一方面从物理层次与逻辑层次两个方面研究中观信息系统固有风险的评价模式;另一方面从一般控制与应用控制两个层面探索中观信息系统内部控制的评价机制。基于BS7799标准对中观信息系统审计进行研究,旨在为IT审计师有效实施中观信息系统审计提供应用指南。     

"上证"A股市场情绪的关键影响因素

文章从投资者认知偏误视角,研究提出了"上证"A股市场情绪的四维量表,系统整合了18个关键影响因素,形成中国证券市场情绪的关键影响因素概念模型.采用"上证"A股市场中152家企业的调研数据,进行验证性因子分析和拟合优度检验.结果表明,12个理论因素按预期模式加载,形成了认知偏误、有限套利、交互传染和本土特性等四个维度,对认识中国证券投资者的决策行为具有一定指导意义.     

行为决策理论及决策行为实证研究方法探讨

作者对行为决策理论发展的历程及各阶段中决策行为的实证研究方法进行了梳理,发现决策行为的实证研究方法在很大程度上决定了行为决策理论发展的进程。在对决策行为一般实证研究方法及其特点进行分析之后,作者认为观察法较适用于决策行为的初步探索性研究;调查法则较适用于一般决策行为的总体状况和特征的研究;如果理论假说源于决策者某些特定的、深层次的主观动机,假设的证实或者证伪又需要大量的检验,实验法的优势比较明显。为了取得对本研究的实证效果,这里对如何将实验法应用于中国投资者决策行为研究做了一次实证性尝试,以供学术争鸣。     

钱包赌戏悖论及其行为的经济学意义

本文对行为经济学的一个重要微观模型———钱包赌戏悖论建立了认知分析框架 ,不仅彻底消解了该悖论 ,还发现了与效用和概率均无关的一种新的非理性效应。这一效应既可能导致无帕累托效率的交易陷阱 ,也可能与效用歧化和概率误判等已知的行为经济学效应协同作用 ,产生更复杂的非理性决策。     

Anticipation of Auction Fever: Entry Decision,Reserve Price and the Choice of Auction Design

This paper analyzes the entry decision of rational bidders who expect to experience auction fever in English auctions. It shows that nonparticipation decision reduces seller's expected profit and this effect may outweigh the positive effect of the auction fever. We analyze the choice between English and second‐price sealed‐bid auctions and the optimal reserve price in English auctions. We show that it might be optimal for the seller to set a reserve price below her own valuation of the object. Finally, we show that the order in which bidders place their bids matters and the first bidder always has an advantage. Copyright © 2011 John Wiley & Sons, Ltd.     

Consequences of a green image of drone food delivery services: The moderating role of gender and age

Drone food delivery services play a significant role in protecting the environment, because the services are operated by batteries that can be charged with electricity. Therefore, this study tried to examine a green image in the context of drone food delivery services. More specifically, this study proposed that a green image of drone food delivery services plays an important role in the formation of attitude toward using the services. In addition, it was hypothesized that the attitude has a positive influence on behavioral intentions including intentions to use, word‐of‐mouth intentions, and willingness to pay more. Lastly, the moderating role of gender and age was proposed during the theory‐building process. A theoretical model, which included 12 hypotheses, was developed and tested using a total of 427 samples collected in Korea. The data analysis results showed that a green image of drone food delivery services has a positive influence on attitude toward using the services, which in turn positively affects three subdimensions of behavioral intentions. Furthermore, gender and age played partly as a moderator. The current paper was the first to study the green image of drone food delivery services, so the findings of this study mean a lot to the theoretical aspect.
