试论我国地方政府债务及其风险控制

地方政府债务是指地方政府承担的,所有需要其在将来运用资产或其它经济资源偿还的义务。它具有以下几个特点:首先,地方政府债务是一种综合性的债务。它可能由多种因素诱发产生,或由其它形式的债务(例如金融债务)转化而来。其次,地方政府债务具有较大的隐蔽性。某些形式的地方政府债务并不直接表现在政府资产负债表上,可能直到需要偿还时才会最终暴露出来。第三,作为最终需要地方财政偿还的债务,地方政府债务一般由地方财政实施控制。     

地方财政体制权责不对称问题研究

地方财政体制权责不对称已经成为分税制后我国地方财政管理体制运行中的一个较为突出的问题。主要表现为：事权划分原则性不强且缺乏法制化基础导致了政府间事权下移，地方政府级次过多与“倒轧账”式的分税模式引起了地方政府间财权上移，转移支付制度不规范造成了地方政府间财力差距日益扩大。为此，我们应选择相应的治理对策来完善我国地方财政体制。     

论传统外部性理论解决环境代际外部性的失效

代际外部性问题主要是人类代际之间行为的相互影响,尤其是前代对后代、当代对后代的影响。在解决代际外部性上,施害者、受害者和政府生活在不同的时空中,新古典方法几乎就无能为力。产权的界定是在产权主体存在的前提下进行的,所以产权在代际进行界定是不可能实现的,所以通过科斯定理来消除代际的外部性也行不通。     

关于完善地方税体系的探讨

地方税体系是分税制财政管理体制的重要组成部分，是我国目前在理论和实践中尚未解决好的问题，提出了完善地方税体系应坚持的原则，在原则指导下，借鉴国外的经验，合理划分中央和地方税收管理权限，科学界定税种归属；优化地方税制结构，完善地方税体系。     

论我国现行缺陷产品召回制度

我国有关缺陷产品召回制度的法律规范或者原则性较强缺乏可操作性、或者位阶较低不具有广泛性、或者针对特定产品适用面较窄。所以,我们应借鉴发达国家的先进经验制定有关缺陷产品召回制度的基本法律和针对特定行业的特别法律,同时建立明确的缺陷产品召回管理体系,以形成保护消费者、维护市场安全与稳定的健全的法律制度和运行机制。     

省级以下土地垂直管理及实施难度研究

阐述土地管理机构垂直管理是满足现阶段市场经济要求的有效管理体制，符合当前行政管理体制改革中垂直管理渐强的趋势。实行机构垂直领导体制是统一当前国土资源管理的基本要求，是当前市场经济阶段处理中央与地方关系，加强中央宏观调控能力和防范经济风险的必然选择。新形势下的垂直管理在实施之初转变领导意识，正确处理国土资源管理部门与地方政府的关系，重视自身的权力监督与约束制度建设。     

Locally Greater Vulnerability to Background Risk

Willingness to take on risk is influenced by the presence of fair and unfair background risks for decision makers who are risk vulnerable as defined by Gollier and Pratt [1996], for these decision makers are more risk averse when they possess such an uninsurable background risk. We present an alternative derivation of the index of local vulnerability based on Diamond and Stiglitz [1974] compensated increases in risk, such that risk aversion increases with the introduction of any small fair background risk if and only if the index of local vulnerability is positive. We establish that the increase in risk aversion is greater for those who are more vulnerable as measured by the index of local vulnerability.     

A Semiparametric Method for Valuing Residential Locations: Application to Automated Valuation

This paper is motivated by automated valuation systems, which would benefit from an ability to estimate spatial variation in location value. It develops theory for the local regression model (LRM), a semiparametric approach to estimating a location value surface. There are two parts to the LRM: (1) an ordinary least square (OLS) model to hold constant for interior square footage, land area, bathrooms, and other structural characteristics; and (2) a non-parametric smoother (local polynomial regression, LPR) which calculates location value as a function of latitude and longitude. Several methods are used to consistently estimate both parts of the model. The LRM was fit to geocoded hedonic sales data for six towns in the suburbs of Boston, MA. The estimates yield substantial, significant and plausible spatial patterns in location values. Using the LRM as an exploratory tool, local peaks and valleys in location value identified by the model are close to points identified by the tax assessor, and they are shown to add to the explanatory power of an OLS model. Out-of-sample MSE shows that the LRM with a first-degree polynomial (local linear smoothing) is somewhat better than polynomials of degree zero or degree two. Future applications might use degree zero (the well-known NW estimator) because this is available in popular commercial software. The optimized LRM reduces MSE from the OLS model by between 5 percent and 11 percent while adding information on statistically significant variations in location value.     

中国财政分权问题研究:一个文献综述

伴随着中国改革开放后经济的持续快速增长,越来越多的国内外学者围绕中国的财政分权问题展开研究。财政分权问题涉及到诸多因素,对其研究必须采用多层次的视角。既有的研究成果多囿于财政分权的某个局部层面,尚未见一个能够解释、分析中国财政分权问题的完整理论框架出现。
