实行消费启动化解经济风险

我国经济增长一直居于高位，但已有几种伴生现象，主要是商品过剩、资金过剩和失业率上升，正蕴育着一些风险或危机。这三者都是由生产过剩所引起。生产过剩意味着消费相对于生产已严重滞后。因此，要根治生产过剩，化解经济风险，关键是大力促进消费增长，并以消费启动经济运行全过程。坚持以消费带动投资增长，这是消费启动所固有的内涵和基本要求。     

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。

Testing separability of public consumption in household decisions

In this paper we propose a sequential strategy, based on the microeconomic approach of the demand theory, in order to test for separability between private and public consumption. The aim of the present work is to verify, using a conditional almost ideal demand system, whether the different components of public consumption exert conditioning effects on the allocative structure of private spending. The empirical estimation of the model and the separability tests are developed for both a demand system in five functional categories of private spending, and for a demand system in six categories, where the private expenditures on those goods and services which can also be offered by the public sector are enclosed in a single functional category. The results of the separability tests, obtained using UK data for the 1974–2000 period, show that public individual consumption plays an important role in modifying consumer choices, while public collective consumption does not affect private consumption behaviours. The relationships between the different components of private spending and public individual consumption are both of substitutability and complementarity; in particular, we find that public individual consumption and the corresponding private expenditures on ‘Health, education, recreation and social protection’ are complements.     

政府责任与中国乳品消费的扩展

从政府责任的角度，提出“完全信息”假设强合理性的观点，从而恢复了新古典经济学关于“完全信息”假设合理性的本来地位。在此基础上，提出政府监管对乳品质量相对完全信息的提供以及对乳品消费拓展具有重要作用。并就政府乳品安全监管机制的选择以及政府在乳品消费习惯形成中的责任进行了探讨。     

商业保险对居民消费影响研究——基于中国省级面板数据的经验证据

当前中国经济社会处于快速转型期,伴随着改革进程的不确定性风险日趋凸显,成为制约居民消费进一步扩张的重要因素。本文采用2003~2017年中国省级面板数据,考察了商业保险对居民消费行为的影响效应及其作用机制。研究发现,以商业保险密度和保险强度为表征的商业保险发展对居民消费有着显著正向影响,相较于农村居民消费,商业保险对城镇居民呈现更强的消费效应,同时财产保险消费效应明显高于人身保险对居民消费影响,进一步地,中介效应检验发现,不确定性缓解可能是商业保险影响居民消费的一个重要机制。基于此,本文认为,构筑完善的商业保险服务体系对于启动居民消费具有重要意义。     

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。
