中低层灵活就业群体主要由下岗工人与农民工组成,他们是就业群体中的弱势群体,如何对他们进行更好的制度安排,促进灵活就业的发展,对于缓解就业压力有着积极的意义.中低层灵活就业中的两大类群体在就业方面既存在共性又存在区别,对此进行分析能更好地促进他们实现灵活就业,并为政府采取有针对性的措施提供参考.  相似文献

Financing Transit Systems Through Value Capture   总被引:1,自引:0,他引:1  
A bstract .   Much of the literature on value capture reports empirical findings on the incidence of rising land values related to distance from a transit stop following the installation of rail transit improvements. This annotated bibliography shows that the elevated value effects of transit access are well documented. The authors maintain that it is now time for transit/land-use research to move from hypothesis testing to practical applications of value capture . Longitudinal models can help predict land-value increments over a period of time, yielding estimates of the total capturable revenues that would support the debt financing of transit improvement projects.  相似文献

This article examines the external shocks and subsequent adjustment processes in the Soviet Union, China, and Hungary during 1974–76, 1979–81, and 1984–87. It compares the experiences of the three socialist countries with regard to external shocks to those of inward-and outward-oriented groups of newly industrializing countries (NICs). In contrast to the NICs, terms of trade effects were of secondary magnitude to export demand effects of external shocks in the three socialist countries during the first two periods. The oil-exporting Soviet Union had beneficial terms of trade effects during the first two periods, with unfavorable effects coming only in the third period. The adjustment responses to the external shocks varied greatly in the Soviet Union from the other two reform-oriented socialist countries and from both groups of NICs. It is interesting to note that the types of responses in the Soviet Union were quite opposite to that one observes for market economies. However, reform-oriented China and Hungary seemed to have response patterns similar to those of market economies, though China's response was similar to the outward-oriented NICs, while Hungary's was similar to the inward-oriented NICs.The authors would like to thank two anonymous referees, as well as Robert Dernberger, Albert Fishlow, Gregory Grossman, Chung Lee, Michael Plummer, Laura Tyson, and Benjamin Ward, for useful comments on this paper. Research in preparing this study was partly supported by a grant from the Institute of International Studies and Center for Slavic and East European Studies of the University of California, Berkeley.  相似文献

中原城市群城市化水平与创新能力协调发展研究   总被引:2,自引:0,他引:2  
经济全球化和区域经济一体化背景下,区域竞争与技术创新日益聚焦于大中城市,创新是城市的灵魂,并引导城市的发展;同时,城市作为创新的"神经中枢",只有区域城市化水平达到一定的层次,相应的创新才会产生.二者的关系在于城市通过物质和能量的输入对创新起塑造作用,而创新则通过物质与能量的输出,对城市具有反作用.城市与创新的相互作用,具体表现为以时空为参照系、城市化水平与创新能力相互作用的界面特征.基于上述理论,运用相关分析、熵权分析和层次分析等方法,对中原城市群9个省辖市的城市化水平和创新能力状况作了综合评价,并在综合和分组两个层面对二者协调关系进行了定量分析.  相似文献

The paper addresses the issues of poverty and social security in a transitional environment on the basis of recent economic developments in Bulgaria. Special emphasis is placed on the need for a new type of social safety net stemming from the radical changes in the political and economic system. The evolution of the social security system in Bulgaria during the transition is analysed focusing on such elements as the pension system, unemployment benefits, child allowances, etc. The empirical analysis is based on extensive use of data from the Bulgarian Household Budget Surveys during the period 1992–1996. Poverty in Bulgaria is measured using different poverty measurements and some quantitative results showing the changing dimensions of poverty in the transition period are presented and discussed in the paper.EES or e-mail at Corresponding author.

The model examines Kornai's observation that in the presence of bailouts, firms' demand for inputs will be greater than would otherwise be the case. This conjecture is examined in a model in which both revenue and cost uncertainty are present and in which firms making losses are partially subsidized and firms making positive profits are partially taxed. The Kornai effect is more prevalent the greater the subsidy rate, the smaller the tax rate and the greater the variance of the random variables through which uncertainty manifests itself. In the case of strongly positively correlated cost and revenue uncertainty, the absolute incidence of the Kornai effect is small.  相似文献
