统分经营的有效结合：农民协会的成功所在——基于萍乡市排上生猪养殖协会的案例研究

本文通过对萍乡市排上生猪养殖协会的案例研究,揭示了农民协会在农业产业化经营中的重要作用:一方面发挥了协会统一经营的功能,为分散的农户提供资金、技术和市场等方面的帮助;另一方面又可以有效地调动农户分散经营的积极性,促进农户生产规模的不断壮大。本文对这种模式进行了分析,得出结论:农民协会统分结合经营模式的成功在于借助于组织实现了农户对生产费用和交易费用的节约。

Incentives for voluntary disclosure

Rule l0b-5 of the 1934 Securities and Exchange Act allows investors to sue firms for misrepresentation or omission. Since firms are principal–agent contracts between owners – contract designers – and privately informed managers, owners are the ultimate firms’ voluntary disclosure strategists. We analyze voluntary disclosure equilibrium in a game with two types of owners: expected liquidating dividends motivated (VMO) and expected price motivated (PMO). We find that Rule l0b-5: (i) does not deter misrepresentation and may suppress voluntary disclosure or, (ii) induces some firms to adopt a partial disclosure policy of disclosing only bad news or only good news.     

2006年诺贝尔经济学奖得主菲尔普斯理论述评

本文介绍了2006年诺贝尔经济学奖得主埃德蒙·菲尔普斯的主要理论贡献。他在宏观经济政策跨期权衡分析、“黄金律”与经济增长、宏观经济政策的“短期—长期”分析、“自然率”、构建宏观经济学的微观基础,以及结构性萧条与繁荣等诸多领域进行了开创性的研究。菲尔普斯的理论和主张对西方经济理论和经济政策的研究都有十分重大的影响,对我国宏观经济问题和政策的研究有一定借鉴意义。     

论电信业互联互通规制创新

互联互通是一个世界性的监管难题,但又是电信业改革的基础。如果没有互联互通,新兴的运营商就难以进入市场,电信业的竞争发展就无从谈起。从我国实际情况出发,有效成分定价原则和整体价格上限法的综合运用不但能提高企业效率,降低成本,促进行业竞争,而且能避免掠夺性定价行为,价格战等行为的发生,它是我国现阶段可以考虑的一种较优的接入定价选择。     

董事责任制度重构： 精准问责、合理容错、宽容失败——以弘扬企业家精神为视角

基于权力（利）、义务、利益、责任与风险相匹配的基本逻辑,新《公司法》既要健全董监高的差异化公平问责规范体系,也要建立人性化合理减免责任制度。董监高问责能力取决于其职位的含权量、含金量、实际控制力与影响力,也取决于所在公司治理实况。要重点锁定并严惩关键少数者,严格区别独董与内部执行董事的法律角色。董监高责任应以过错责任为主、严格责任为例外。为精准识别董监高过错,建议采取法商、德商、智商、情商合一的理性人标准。要坚持责任自负为主、连带责任为辅。连带责任规范要保持统一化与谦抑化,赋予董监高在承担连带责任后的法定追偿权。要坚持有限责任为主、无限责任为辅。董监高对第三人不负责任为原则,负责为例外。建议精准甄别董监高个人责任与公司法人责任。章程或公司决议对法定代表人代表权的限制只要登记、备案或公示,即可对抗相对人。建议导入商事判断规则,允许公司自主豁免或减轻董监高责任,要求董监高自担最低责任限额,导入董监高责任保险制度。董监高问责机制要与股权激励相匹配。     

Efficient markets and Bayes’ rule

Summary. A series of financial anomalies motivated the development of new theories that modify the rational expectations ideal. Two possibilities have been systematically explored. The literature on behavioral finance relaxes the assumption that agents form beliefs according to the laws of probability and assume, instead, that simpler heuristic rules are used. Another stream of the literature assumes that agents process information according to Bayes rule, but do not posses sufficient information to know the true data generating process. In this paper, Bayesian and Behavioral agents coexist and trade in a standard dynamic asset pricing model. A long-standing conjecture is demonstrated. It is shown that, under suitable assumptions, Bayesian agents drive Behavioral, non-Bayesian agents out of the market. Hence, asset prices are eventually determined under the Bayesian paradigm.Received: 3 June 2004, Revised: 17 September 2004, JEL Classification Numbers: D83.Preliminary versions have circulated under the titles Markets Favor Bayesian Models and Market Selection of Empirical Models under Limited Information.

"谨慎投资者规则"与我国基金管理人注意义务的法律完善

美国信托法中的“谨慎投资音规则”是在历经法定投资表和谨慎人规则两个阶段的演进中吸收了现代投资组合理论而形成的。“谨慎投资者规则”作为受托人的一项法定投资原则，不仅比较契舍当今证券投资的实际需要，而且也很好地防范了基金管理人对投资权力的滥用，目前已成为越采越多国家规范基金管理人注意义务的主要依据。我们很有必要对之加以吸收和借鉴，以使我国基金管理人注意义务的内容更为精细化。     

The Wealth Effects of Fairness Opinions in Takeovers

This paper explores the wealth effects associated with a bidder's decision to solicit a fairness opinion in a takeover transaction. Using a hand‐collected sample with bidders’ filing proxy statements, this paper finds that the use of fairness opinions does not negatively affect bidder shareholders’ wealth, a finding that contradicts prior studies’ findings. In addition, I find a positive wealth effect associated with bidder use of fairness opinions in the post‐Rule 2290 period. Collectively, these results are consistent with a fairness opinion being used by bidder management as a means to facilitate transactions rather than a mechanism to entrench management.     

Does the strength of the legal systems matter for trade in insurance and financial services?

This paper investigates if the strength of the legal system impacts on the trade in insurance and financial services in the high-income OECD and developing countries. Our findings reveal a statistically significant positive correlation of rule of law and regulatory quality with the exports and imports of insurance and financial services. Our empirical findings also reveal a negative and statistically significant correlation of contract enforcement with the exports and imports of insurance and financial services. We conclude that strengthening the rule of law and contract enforcement mechanisms can facilitate higher levels of trade in insurance and financial services.
