Delaying integration of immigrant labor for the purpose of taxation

Delayed integration (DI) is a rule for taxing migrants. It requires that immigrants be taxed in the host country only after some period of transition. Conversely, emigrants are released from the obligation to pay taxes only after a certain period. DI is an alternative to the Employment Principle and the Home-Country Principle. The former governs the international taxation of labor. The latter is a close substitute for the Nationality Principle, on which US tax law is based. The paper studies DI in a setting which allows one to trade off the efficiency costs of distortionary taxation and of wasteful government.     

不对称信息理论与会计信息披露问题研究

会计信息披露是资本市场实现资源有效配置的基础,也是会计工作的基本目标之一。本文通过不对称信息理论深入分析了目前我国会计信息披露中产生的各种问题,并找出其中的内在动因,为规范我国会计信息披露制度进行了深入的思考和分析。本文的结构分为三个部分,首先简单介绍一下不对称信息理论及其基本理论,其次分析目前我国证券市场上会计信息披露存在的各种问题,最后利用不对称信息理论针对这些问题进行深入的分析研究,并得出相应的结论。     

公众期望与会计信息真实性的关联分析

公众对会计的期望与对会计行为的认识之间存在期望差距,基于不同期望水平对会计信息失真现象所作的分类揭示了会计信息真实性的内涵。通过公众期望与会计信息真实性的关联分析可以发现,加强公众与会计界的沟通理解以及强化会计信息失真的治理,是解决会计信息真实性问题的有效途径。

Does seeing more deeply into a game increase one’s chances of winning?

The substantively rational value of the games studied in this paper does not help predict subject performance in the experiment at all. An accurate model must account for the cognitive ability of the people playing the game. This paper investigates whether the variation in measured rationality bounds is correlated with the probability of winning when playing against another person in games that exceed both players’ estimated rationality bound. Does seeing deeper into a game matter when neither player can see to the end of the game? Subjects with higher measured bounds win 63 percent of the time and the larger the difference the more frequently they win.     

信息约束下的金融监管与银行声誉

如何在信息不对称的约束条件下降低金融风险、提高监管绩效,是金融监管中的一项重要课题.本文分析了信息结构对于监管的重要性,认为声誉机制的建立可以降低银行与监管部门之间信息不对称的程度和风险发生的概率,并运用KMFW模型,分析了不对称信息下银行声誉机制减少违规动机的过程,指出应该注重激励相容的制度安排,将外部监管与自律有机结合起来,促使银行自发选择接受监管且减少进行高风险投资的动机,这是信息不对称条件下提高监管效率的重要策略.结合我国实情,本文提出可通过银行风险评级、建立可置信的惩罚机制、完善银行内部治理机构、改进监管人员激励约束机制、构建和完善金融监管信息系统等措施,建立健全银行声誉机制,以进一步改善监管绩效.     

关于中国经济发展与非正规就业的现状研究

本文回顾了国内外对非正规就业的理论研究，通过宏观上对非正规就业与经济发展程度在国际国内差异的比较，认为我国非正规就业与现今的经济发展阶段相适应，在就业数量和比例方面具有较大就业岗位创造的潜力，并且，与国际普遍认知不同，中国非正规就业与正规就业之间存在替代而非互补的关系，同时指出非正规就业重要性和其就业现状的不匹配，将在未来对经济发展产生瓶颈式的制约，并提出相应的微观和宏观建议，以促进我国的经济长远发展和社会稳定。     

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.
