构建和谐社会需要正确处理的十大关系

构建和谐社会,是一个长期的过程.在经济高速发展的轨道上,各种利益、各种关系的摩擦、碰撞是激烈的.构建和谐社会,要处理的关系非常多.其中,尤其要正确处理好十个主要方面的关系:经济增长与可持续发展的关系;人口与就业的关系;经济和教育的关系;城市和乡村的关系;高新技术产业与传统产业的关系;积累和消费的关系;内需和外需的关系;强势群体与弱势群体的关系;改革与发展的关系;中国特色与国际惯例的关系.     

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.

“Itô's Lemma” and the Bellman Equation for Poisson Processes: An Applied View

Using the Hamilton-Jacobi-Bellman equation, we derive both a Keynes-Ramsey rule and a closed form solution for an optimal consumption-investment problem with labor income. The utility function is unbounded and uncertainty stems from a Poisson process. Our results can be derived because of the proofs presented in the accompanying paper by Sennewald (2006). Additional examples are given which highlight the correct use of the Hamilton-Jacobi-Bellman equation and the change-of-variables formula (sometimes referred to as ``Itô's Lemma'') under Poisson uncertainty.     

Financial crisis and persistence: evidence from sticky expectations consumption growth model

We estimate the degree of stickiness in aggregate consumption growth for the U.S. considering the effects of the Great Recession. The behavior of stickiness estimate in the crisis is somewhat as the U-shaped pattern. Our findings imply that during the crisis consumers’ attentiveness to aggregate information has slightly increased, thereby reducing the persistence of aggregate consumption growth. However, the reduction in persistence is transitory. Since 1980, the U.S. faced five recessions and in most of them the degree of stickiness declined, albeit temporarily.     

刍议中国劳动力价格与经济增长路径转变

改革开放以来,中国经济取得了令世人瞩目的成就,与此同时,经济运行中不和谐的因素也日益增加.投资和消费的比例关系失衡,表现为投资率偏高而消费率偏低.从劳动者收入入手研究投资、消费比例问题,在研究中国劳动力价格的现状后得出结论:相对于居民生活密切相关的粮价、油价、水电费、通讯费、教育费、医疗费来说,中国劳动力价格太低,因此,提高劳动力价格,增加其收入才是破解投资消费失衡的"密钥",也是促进中国经济从依赖投资的增长方式向依靠消费拉动经济增长方式的增长路径转变的"治本之道".     

公共支出与经济增长关系的新视角——基于省际面板数据的经验研究

本文在三个前提假设的基础上,构建了一个简单的解释经济增长的理论框架,并由此建立了两个计量模型,通过对中国14个省区1991至2003年的面板数据的实证检验,得出在转型经济时期的中国,公共支出、政府消费性支出都对经济增长有显著的正向作用,而公共支出中的转移性支出与经济增长呈现非常弱的正相关关系.实证检验结果的政策意义在于,(1)作为宏观调控的手段之一,公共支出仍然对经济增长有显著正效应.(2)有关政府部门应当重视并发挥好公共支出中转移性支出的功能.     

食品供应链安全问题的信号博弈模型

基于食品供应链上安全信息不对称的特点以及零售企业运营状况,针对滥用食品安全标签(如无公害、绿色、有机食品标签等)的现象,以食品生产商和消费者作为博弈方,建立信号博弈模型,分析信号博弈的三种贝叶斯均衡及其条件,得出了信息不对称情况下安全食品生产商的损失函数,以及政府控制食品安全的策略。
