根据消费的生命周期——持久收入假说,股票市场的财富增加对居民消费有促进的作用,这就是所谓的“财富效应”。国外的许多研究证实了股票市场财富效应的存在,而国内的一些研究则不认为我国股票市场存在财富效应。针对这种状况,文章以我国城镇居民为例,对我国股票市场的财富效应进行了再检验,结果发现.即使针对城镇居民这一拥有股票数量相对较多的群体而言,仍然没有显示出股票市场的财富效应。对这个结果,文章进行了初步的解释并提出有关的政策建议。 相似文献

在北方,冬季施工一直是建筑业最为头疼的问题。某厂房装配车间大型设备基础需要冬季施工.其平面尺寸为44mx44m.最深处为-11.10m.最浅处为-2.73m。鉴于工期的要求及地基的越冬维护.选用了塑料暖棚法进行冬季施工。大棚内设简易采暖(利用厂房的暖风机设备)。白天利用太阳能提高棚内温度.夜间视气温情况间歇供暖。以保持坑底的温度在0℃以上。实践证明.太阳能暖棚法冬季施工效果很好.从大棚的物质用量及使用效果上看.非常适用于北方大中型地下工程的冬季施工。 相似文献

Social Security and personal saving: 1971 and beyond 总被引:1,自引:0,他引:1
Feldstein (1996, 1974) reported that Social Security in the U.S.A. reduced personal saving (“saving”) in 1992 (1971) by $416
($61) billion. I reestimate his life-cycle consumption specification using data from the latest NIPA revision, correct his
calculations, and find that the implied reduction in 1992 (1971) saving is now $280 ($22) billion, 48% (16%) of actual net
private saving, with a standard error of $114 ($14) billion. If structural breaks around WWII and the 1972 Social Security
amendments (which raised real per capita SSW by 22%) are allowed, and the market value of Treasury debt included in the specification, the reduction in 1971 and 1992
saving attributable to Social Security is at most 0.55 times its standard error, and 12% of net private saving. I then reestimate
the preferred specification of Coates and Humphreys (1999), allowing for these structural breaks and relaxing other restrictions.
The implied effect of Social Security on saving is again statistically zero.

戊烷的生产与市场分析 总被引:5,自引:0,他引:5
戊烷原料主要来源于炼油厂。戊烷产品用途广泛,可用作发泡剂、溶剂、化工原料等。目前国内高纯度异戊烷、正戊烷、环戊烷及混合戊烷发泡剂生产厂有36家,生产能力150kt/a左右.我国戊烷的年消费量近66kt,其中,EPS(发泡聚苯乙烯)戊烷发泡剂的消费量约占总消费量的45%;聚氨酯的发泡剂消费戊烷约占总消费量的50%;线性低密度聚乙烯戊烷载溶剂消费量约占总消费量的5%。国内戊烷供大于求,但高档产品供应不足。所以,“十五”期间新建装置一定要采用国内较为先进的工艺技术,采用较廉价的原料气,确保产品质量,最大限度的降低生产成本,同时加强市场开发,提高产品的市场竞争力。 相似文献

In this article we analyse whether the Ricardian equivalence hypothesis is a valid approximation for Spains economic reality or whether there exist deviations from that situation which would be more in line with the conventional Keynesian perspective of the effects of debt on private consumption-savings decisions.Our aim is to contribute to the rather sparse empirical literature on the subject for the Spanish case. The analysis is based on annual aggregate data for Spain covering the years 1955 to 2000, and uses both the structural and the Euler equation approaches to test the neutrality proposition, and is thus to be considered as a generalization of foregoing work on the Spanish economy.The findings indicate that support for Ricardian equivalence is mixed, while we also find very little support for the Keynesian specification of consumption and fiscal policy.First revision received: March 2003 / Final version received: October 2003The authors wish to thank M. Ferré, J.M. González-Páramo, A. Marchante, P. Meguire, F. Pedraja, J.L. Raymond, J. Salinas and two anonymous referees for their helpful comments and suggestions on this paper. We also thank the participants in the V Encuentro de Economía Aplicada (Oviedo, Spain, June 2002) and the XVII Simposio de Análisis Económico (Salamanca, Spain, December 2002) for their comments. Any remaining defects are our responsibility.

Household debt relative to disposable income increased from 60% in 1980 to 104% at the end of 2003. ‘Buying on credit’ has become so popular that an increasing number of firms generate more profit from financing than from selling their products. In this paper, we show that rising income inequality has substantially contributed to increased consumer borrowing. Income inequality affects all components of total household debt, but the impact is strongest on non-revolving debt (installment loans), which is used to finance the purchase of consumer durables. We argue and provide evidence that the income inequality effect on consumer borrowing is a result of conspicuous consumption. Rising income inequality has forced households with smaller income gains to use debt to keep up their consumption level relative to households with larger income gains.JEL Classification: D12, G29, J31, M30 相似文献
