投资者股利政策偏好及其交易行为

本文选取了2002-2004年深沪两市派发股利的公司作为研究样本,通过T检验和一元线性田归模型发现,投资者偏好混合股利和股票股利主要是由于这两种股利形式带来较之现金股利更高的回报率.同时,在回报率较高时往往伴随有显著的交易量增加,调整后的判定系数在1%的水平上显著,但是也表现出一定的滞后性.     

公共投资就业效应的一个解释——基于CES生产函数的分析及其检验

本文在分析CES生产函数过程中引入劳动力市场,探讨了公共投资与就业的联系.本文认为,公共投资是通过劳动工资弹性来影响就业的.公共投资增加会引起劳动需求的工资弹性提高,而公共投资的溢出效应则会导致企业实际工资支出水平降低,两方面原因的共同作用引起就业的增长.在此分析基础上,本文用ARDL方法构建了一个多方程模型,并用中国的数据进行了检验.为提高分析的有效性,我们用SUR方法对模型做了系统估计,并进一步通过方程转化对变量的短期波动和长期均衡关系进行了探讨.实证研究发现,中国的公共投资增长在短期减少就业,但长期内对就业有显著的正效应.     

公共资本生产率的比较研究——基于长三角21城市公共资本边际生产率的实证分析

近10年来长三角的政府公共投资（分配）过多地流向了上海、苏州、杭州、南京等核心城市，使这些城市的人均公共资本拥有量大幅上升，从而引发了其边际生产率递减情况的发生。但它们的资本利用效率或技术创新水平没有明显提升（或下降），不足以抵消其资本边际生产率下降的趋势。对这些大城市的经济发展来说，公共投资对其经济增长的意义已经在数量上表现得不明显，但对正处于经济快速增长期且资本边际生产率呈递增态势的长三角外缘中小城市而言，公共投资却有着积极意义。     

基于Miller-Orr模型的省级政府现金管理实证研究

现代国库制度的两项重要功能是,确保对预算执行过程的有效监控和对政府现金资源的妥善管理,而高效的现金管理系统对监控预算执行起着重要的支持性作用.在政府现金管理已逐渐为政府和理论界所关注的背景下,本文从政府现金管理的基本理论、本质及意义入手,以实际调研数据为基础,通过将西部某省2003-2005年的实际数据运用到修正的Miller-Orr模型中,较准确的测算出了2006年该省国库现金月余额的控制范围,为建立省级政府现金管理模式提供了有益的参考.     

The effectiveness of government spending on education and health care in developing and transition economies

Recent studies show that corruption is associated with higher military spending [Eur. J. Polit. Econ. 17 (2001) 794] and lower government spending on education and health care [J. Publ. Econ. 69 (1998) 263]. This suggests that policies aimed at reducing corruption may lead to changes in the composition of government outlays toward more productive spending. However, little empirical evidence has been presented to support the claim that public spending improves education and health indicators in developing and transition countries. This paper uses cross-sectional data for 50 such countries to show that increased public expenditure on education and health care is associated with improvements in both access to and attainment in schools, and reduces mortality rates for infants and children. The education regressions are robust to different specifications, but the relationship between health care spending and mortality rates is weaker.     

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.     

企业间专业化分工与产业集群组织发展——基于交易费用的分析视角

从劳动的专业化分工入手,本文通过揭示产业集聚降低区域企业交易费用,指出发生在产业关联企业间而不是企业内的专业化分工是产业集群组织发展的基本动力。大量的产业关联企业在区域内聚集发展,不仅能够降低企业内生交易费用,而且能够降低外生交易费用,使人们劳动的专业化分工深化沿着大量地理接近的企业间而不是数量有限的企业内进行,从而为产业集群发展给出了一个具有新制度经济学含义的理论解释。     

Wealth inequality and collective action

We study the effect of inequality in the distribution of endowments of private inputs (e.g., land, wealth) that are complementary in production with collective inputs (e.g., contribution to public goods such as irrigation and extraction from common-property resources) on efficiency in a class of collective action problems. We focus on characterizing the joint surplus maximizing level of inequality, making due distinction between contributors and non-contributors, in a framework that allows us to consider a wide variety of collective action problems ranging from pure public goods to impure public goods to commons. We show that while efficiency increases with greater equality within the groups of contributors and non-contributors, so long the externalities (positive or negative) are significant, there is an optimal degree of inequality between these groups.     

Robust political economy

This paper introduces the idea of “robust political economy.” In the context of political economic systems, “robustness” refers to a political economic arrangement's ability to produce social welfare-enhancing outcomes in the face of deviations from ideal assumptions about individuals' motivations and information. Since standard assumptions about complete and perfect information, instantaneous market adjustment, perfect agent rationality, political actor benevolence, etc., rarely, if ever actually hold, a realistic picture and accurate assessment of the desirability of alternative political economic systems requires an analysis of alternative systems' robustness. The Mises-Hayek critique of socialism forms the foundation for investigations of robustness that relax ideal informational assumptions. The Buchanan-Tullock public choice approach complements this foundation in forming the basis for investigations of robustness that relax ideal motivational assumptions. JEL Code B53, P16, P26     

美国财政分权的效率分析

美国作为一个高度发达的市场经济国家,不但在经济发展领域里取得了令人瞩目的成就,而且在制度的设计、创新和发展等方面也有许多值得借鉴之处,美国财政分权体制就是其中之一.本文在分析财政分权效率的含义及要求的基础上,从美国政府问事权和财权划分明确且相互匹配、科学合理的转移支付制度、分权与制衡并存的预算机制、地方政府自治以及整个财政分权体制的法律依据等方面分析了美国财政分权高效的原因.
