会计国际化背景下的我国会计信息质量特征研究

会计信息质量特征是财务会计概念框架的重要组成部分。本文采用规范分析方法对西方国家的会计信息质量特征进行了国际比较，并结合实证研究结论对影响我国财务会计信息质量特征的因素进行了现状分析。最后指出在当前特殊的环境下确立我国财务会计信息质量特征体系，应该同时兼顾国际协调与中国特色，建议在透明度的总体要求下，依次将会计信息质量特征设定为：可靠性，相关性，充分披露。     

大户与散户在证券市场的博弈

通过对Laffon的模型进行了改进，将散户的效用函数改成了常系数绝对风险厌恶的负指数形式。Laffon的结论为：当θ1,θ2相距不远时，大户与散户都偏好混同均衡。而改进后的模型却找到了θ1,θ2的距离在一个具体的范围内，大户与散户才都偏好混同均衡。     

高校图书馆信息服务中的信息不对称现象及对策

信息不对称理论是微观信息经济学研究的一个核心内容，它普遍存在于社会生活的各个方面，图书馆同样存在着严重的信息不对称问题。本文揭示了图书馆信息服务中存在的几种信息不对称现象，并提出了抑制信息不对称的策略。     

业财融合背景下的信息系统审计研究

Pricing, learning, and strategic behavior in a single-sale model

Summary. We analyze an infinite horizon model where a seller who owns an indivisible unit of a good for sale has incomplete information about the state of the world that determines not only the demand she faces but also her own valuation for the good. Over time, she randomly meets potential buyers who may have incentives to manipulate her learning process strategically. We show that i) the seller's incentives to post a high price and to experiment are not necessarily monotonic in the information conveyed by a buyer's rejection; and ii) as the discount factors tend to one, there are equilibria where the seller always ends up selling the good at an ex-post individually rational price.

Herd Behaviour in Adoption of Network Technologies

In technology adoption, herd behaviour can lead to a suboptimal outcome as shown, among others, by Choi (1997). However, empirics find little support for the idea that a less efficient technology can conquer the market and lock out a more efficient one. Accordingly, we improve and generalize Choi's results, by introducing an additional source of uncertainty: the economic environment. We investigate how the economic environment can affect herding and consequently the efficiency of the technology choice. The result is a smaller adoption bias. In the limit, firms may optimally experiment with the new technology that turns out to be social welfare improving.     

Subjective recursive expected utility

We axiomatize a subjective version of the recursive expected utility model. This development extends the seminal results of Kreps and Porteus (Econometrica 46:185–200 (1978)) to a subjective framework and provides foundations that are easy to relate to axioms familiar from timeless models of decision making under uncertainty. Our analysis also clarifies what is needed in going from a represention that applies within a single filtration to an across filtration representation.Part of this research was conducted when Ozdenoren visited MEDS in Fall 2003. We thank Tapas Kundu, Costis Skiadas, Jean-Marc Tallon and Tan Wang for helpful discussions and also thank audiences at Koc University, Northwestern University, the CERMSEM conference “ Mathematical Models in Decision Theory” at Universite Paris I, and the FUR XI conference on foundations and applications of utility, risk and decision theory     

Conditions for Asymmetric Information Solutions when Alliances Provide Acquisition Options and Due Diligence

One main problem with both acquisitions and alliances is separating the attractive partners from the rest. An additional problem with alliances is getting each partner to provide its best assets and efforts. One solution offered for the acquisition adverse selection problem is due diligence through a pre-acquisition alliance; however, none of the papers recommending such an approach analyze the alliance adverse selection and moral hazard problems. This paper presents the first formal model of joint venturing as acquisition due diligence, detailing how the joint solution works and under what conditions.revised version received October 20, 2003
