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。     

我国服务业增加值的核算问题

本文集中讨论我国服务业增加值估算中存在的问题。由于历史原因和服务业本身的一些特点 ,我国现价服务业增加值被严重地低估了 ,服务业增长率计算也可能存在着偏差。对服务业增加值的以往研究均受到基础数据的限制而未能根本地解决这些问题。服务业统计核算的缺陷严重地阻碍着经济分析和经济决策。因此 ,改善我国服务业统计核算是当务之急。从长远的角度来说 ,服务业增加值核算的改善在很大程度上取决于统计调查的完善。但是 ,在现有的条件下 ,仍然有很大的改善余地。     

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.     

竞争性行业管理体制改革的方向和重点

竞争性行业是指所有不具有自然垄断性质的行业.虽然我国竞争性行业管理体制改革已取得了重大进展,但还存在政企不分、职能转变不到位、部门垄断、行业进出通道不畅、行业管理法规不健全等问题.改革的方向和重点是:推进政企分开、政资分开、政监分开和政社分开,理顺行业管理体系,打破部门垄断和地方保护,疏通行业进入和退出通道,完善行业管理法规等.     

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     

Existence of a competitive equilibrium in a one sector growth model with heterogeneous agents and irreversible investment

Summary. We prove existence of a competitive equilibrium in a version of a Ramsey (one sector) model in which agents are heterogeneous and gross investment is constrained to be non negative. We do so by converting the infinite-dimensional fixed point problem stated in terms of prices and commodities into a finite-dimensional Negishi problem involving individual weights in a social value function. This method allows us to obtain detailed results concerning the properties of competitive equilibria. Because of the simplicity of the techniques utilized our approach is amenable to be adapted by practitioners in analogous problems often studied in macroeconomics.

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.
