EDGAR on the internet: The welfare effects of wider information distribution in an experimental market for risky assets

Policies such as the SEC’s Fair Disclosure Rule, and technologies such as SEC EDGAR, aim to disseminate corporate disclosures to a wider audience of investors in risky assets. In this study, we adopt an experimental approach to measure whether this wider disclosure is beneficial to these investors. Price-clearing equilibrium models based on utility maximization and non-revealing and fully-revealing prices predict that in a pure exchange economy, an arbitrary trader would prefer that no investors are informed rather than all are informed; non-revealing theory further predicts that an arbitrary trader would prefer a situation in which all traders are informed rather than half the traders are informed. These predictions can be summarized as “None > All > Half”. A laboratory study was conducted to test these predictions. Where previous studies have largely focused on information dissemination and its effects on equilibrium price and insider profits, we focus instead on traders’ expected utility, as measured by their preferences for markets in which none, half, or all traders are informed. Our experimental result contradicts the prediction and indicates “Half > None > All”, i.e. subjects favor a situation where a random half is informed. The implication is that in addition to testing predictions of price equilibrium, experiments should also be used to verify analytical welfare predictions of expected utility under different policy choices.

美国宪政史上的政治言论自由案——罗尔斯的观点

在一个民主社会中,言论及出版自由是宪法所保障的基本权利.但是对于政治言论自由,究竟哪些才是此类言论最关键的部分,以及对这类言论的规范该如何拿捏才算合理适当,都是各国宪政史上一个争议不断的课题.罗尔斯不同于早先的Meiklejohn从"自治"的立论出发,转而从社会正义的视角切入,为此类言论提供一个更合理坚实的基础.本文的主旨即在阐述罗尔斯对于政治言论自由的立场和观点.     

动态比较优势与中国目标产业选择实证分析

Using data envelopment analysis approach to estimate the health production efficiencies in China

By using Data Envelopment Analysis approach, we treat the health production system in a certain province as a Decision Making Unit (DMU), identify its inputs and outputs, evaluate its technical efficiency in 1982, 1990 and 2000 respectively, and further analyze the relationship between efficiency scores and social-environmental variables. This paper has found several interesting findings. Firstly, provinces on frontier in different year are different, but provinces far from the frontier keep unchanged. The average efficiency of health production has made a significant progress from 1982 to 2000. Secondly, all provinces in China can be divided into six categories in terms of health production outcome and efficiency, and each category has specific approach of improving health production efficiency. Thirdly, significant differences in health production efficiencies have been found among the eastern, middle and western regions in China, and among the eastern and middle regions. At last, there is significant positive relationship between population density and health production efficiency but negative relationship (not very significant) between the proportions of public health expenditure in total expense and efficiency. Maybe it is the result of inappropriate tendency of public expenditure. The relationship between abilities to pay for health care services and efficiency in urban areas is opposite to that in rural areas. One possible reason is the totally different income and public services treatments between rural and urban residents. Therefore, it is necessary to adjust health policies and service provisions which are specifically designed to different population groups. __________ Translated from Jingji Yanjiu 经济研究 (Economic Research Journal), 2006, (7): 92–105

财务会计信息与公司治理

财务会计系统不但给公司控制机制提供直接的财务信息,而且还提供股票价格中反映的所有间接信息。会计治理研究中的一个基本目标是为财务会计提供的信息,在多大程度上减缓由所有权和经营权两权分离所带来的代理问题,以及减少信息不对称问题提供证据。本文着重探讨财务会计信息在公司治理机制中的作用,公司治理机制对财务会计信息反作用的互动研究,并提出了公司治理的对策。
