中国经济发展与社会保障关系的实证研究

从社会保障产生以来,人们更多地是从社会公平的角度看待社会保障的经济作用。事实上,社会保障与经济发展的相互关系一直是经济学家研究的热点问题之一。由于社会保障通过影响个人决策进而影响经济运行中的资本积累,它对经济发展势必产生一定的影响。本文通过实证方法检验中国社会保障与经济发展之间的内在关系,从整体上研究中国社会保障与经济发展的关系,指出当前我国经济发展是社会保障增长的单项原因。     

中国碳排放与经济增长关系的实证研究

本文选取1978—2006年中国碳排放总量和经济总量的时间序列数据,从碳排放与经济增长的相关关系出发,通过相关系数分析、回归分析及其检验和因果关系阐述,研究中国碳排放与经济增长的演替轨迹,并建立碳排放与经济增长的计量模型。研究结果表明:在目前状况下,中国经济增长是碳排放增长的推动原因,随着中国经济的增长,二氧化碳排放量也呈逐渐增多的趋势,但单位GDP碳排放逐渐降低,即碳排放增长率明显低于经济增长率。

Funded social security and economic growth

This paper investigates the relationship between economic growth and a fully funded social security system in an overlapping generations model with family altruism. It is shown that funded social security may harm growth if there are operative bequests within the family.     

Migration,social security,and economic growth

This paper studies the effect of population aging and international migration on economic performance. Fertility is endogenized so that immigrants and natives can have different fertility rates, which provides a more realistic view of policy effects. Fertility is an important determinant to the tax burden of social security since it affects the quantity and quality of future tax payers. We find that introducing immigrants into the economy can reduce the tax burden of social security. If the survival probability of young agents to old age (or the replacement ratio) is high enough, the growth rate of GDP per worker for an economy with international migration will be higher than for a closed economy. Regarding migration policies, our numerical results indicate that economic growth rate of GDP per worker will first decrease then increase as the flow of immigrants increases. Attracting more skilled immigrants will enhance economic growth.     

Population growth and economic and social development

This article sets forth 3 positions on population growth: 1) rapid population growth is a central development problem that implies lower living standards for the poor; 2) proposals for reducing population growth raise difficult questions about the proper domain of public policy, yet it is acceptable for governments to attempt to influence private decisions about family size; and 3) the experience in many developing countries shows that quick, effective measures can be taken to reduce fertility. Rapid population growth has slowed development because it exacerbates the difficult choice between higher consumption in the present and the investment needed to bring higher consumption in the future. As populations grow, larger investments are needed just to maintain current capital/person. It further threatens the balance between natural resources and people and creates severe economic and social problems in urban areas. Public policy must provide alternative ways for poor families to secure the benefits provided by large family size. That is, governments need to provide tangible evidence that it really is in the best interests of parents to have fewer children. Also required is greater infomation about and access to fertility control. When family planning services have been widespread and affordable, fertility has decline faster than social and economic progress alone would predict. There is a need for immediate action to improve women's status and to make education, family planning, and primary health care more available. Although economic and social progress help to slow population growth, rapid population growth hinders development. Thus, governments must act simultaneously on both fronts. Accumulating evidence on population growth in developing countries shows that is the combination of social development and family planning that reduces fertility.     

金融发展与中国二元经济结构转换

传统的二元经济理论只考察了资本因素在经济发展不平衡中的作用,并没有把金融发展因素纳入其中进行分析,而传统的金融发展理论研究的焦点主要集中在金融发展与经济增长的关系上,对金融发展与二元经济结构之间的关系重视不够。中国是一个典型的城乡二元经济结构的发展中国家,而我国城乡金融发展差距是城乡经济发展差距存在的一个重要原因。因此,解决我国二元经济结构问题的一个重要方面就是要均衡城乡金融发展。

我国新一轮经济发展与宏观调控政策抉择

宏观调控的目的是为了抵御经济的非正常波动,因而一般来说要逆经济风向而行,采取反周期政策.但另一方面,我国经济的起伏波动在很大程度上是由于政府在不同时期出台的不同宏观经济政策造成的.当前,宏观经济调控背景的转变要求宏观调控手段的转变.从以往的经验来看,熨平经济周期性波动,单一政策效果未必良好,需结合其他政策才能有效地避免或减轻周期性波动的负效应,稳定宏观经济运行.     

Financial development and economic growth in Australia: An empirical analysis

The paper empirically examines the dynamic relationship between financial development and economic growth in Australia in terms of bank-based and market-based financial structure. A time-series approach using the VAR Model is used to provide evidence for the dynamic relationship. The paper provides empirical evidence on the causal impact of the financial market on the economic growth of the Australian economy. The results suggest that financial intermediaries and financial markets have different impacts on economic growth given their diverse roles in the domestic economy. In particular there is evidence of causality from economic growth to the development of the financial intermediaries. On the other hand, development in the financial markets causes economic growth but there is no evidence of any causality from economic growth to financial markets. The sensitivity test using different interest rates does not change the results.I Jel classification: O16, G18, G28I We would like to thank Tilak Abeysinghe and Rajagurn Gunasekaran for their helpful comments on the first draft.

The economic effects of social security: Toward a reconciliation of theory and measurement

In this paper we argue that actuarial valuation of Social Security benefit streams is theoretically inconsistent with the assumption of pure life cycle motives. Instead, we show that the simple discounted value of future benefits (ignoring the possibility of death) is often a good approximation to the relevant concept of value. This observation motivates a re-examination of existing empirical evidence concerning the economic effects of Social Security. We focus our attention on studies of distributional equity and personal saving behavior. In both cases we argue that the use of simple, rather than actuarial, discounting of survival-contingent income streams produces results that differ dramatically from previous findings. Specifically, estimates based on actuarial valuation may overstate the importance of redistribution between and within generations, and may understate the depressive effect of Social Security on personal wealth accumulation by a factor of three or more.     

从“倒萨”战及其影响看中国经贸的安全与发展

自去年2月，美国总统布什在其国情咨文中提出了所谓的“邪恶轴心”国家以来，美国和世界民众的目光就从阿富汗被引到对伊拉克战争的关注中来了。经过十个月来的理论修补和备战运作，以美国为首的个别国家已经基本上完成了对伊战争的战略和战术的部署。去年11月8日，联合国安理会一致通过了有关伊拉克问题的1441号新决议，表明美国已基本上达到了建立“倒萨”国际联盟避免采取单边行动武力打击伊拉克的目的；11月在布拉格召开的北约高峰会中，美国进一步抹平了盟国之间的分歧和不同意见，落实了各项分工和任务，包括建立一支2.1万人的快速反…
