FAMILIES, TIME AND MONEY IN CANADA, GERMANY, SWEDEN, THE UNITED KINGDOM AND THE UNITED STATES

Using microdata from the Luxembourg Income Study, we assess "time crunch" for families with children in Canada, Germany, Sweden, the U.K. and the U.S. Both theory and empirical evidence suggest that both time and money are important inputs to the well-being of parents and children. We present cross-country comparisons of "total available adult hours" under different assumptions about the varying time needs of families of different size. We also present estimates of "time shortages." In all cases, we provide separate estimates for families located at different points in the country income distributions, since being short of both time and money is likely to be particularly problematic. Although paid work hours are highest for high-income families, we nonetheless find significant numbers of lower-income families in which parents work very long hours in the paid labor market; this is particularly the case in the U.S.

三峡外迁移民的社会适应性及其影响因素研究——对江苏227户移民的调查

通过实证调查的资料对三峡外迁移民的社会适应状况作了描述,对影响其社会适应性的因素进行了分析。就总的社会适应性而言,一半以上的移民已基本适应了迁入地的生活。与三峡外迁移民的社会适应状况密切相关的因素主要有搬迁前后经济收入的差异、当地居民的态度、语言适应性、政府关心状况、迁入地治安状况、住房条件的差异。     

我国创业投资的回报率及其影响因素

基于1999年到2003年间我国56个本土创业投资退出项目的数据,本文对我国创业投资退出项目的投资回报率及其影响因素进行了实证研究。结果表明:(1)国有创业投资机构退出项目的平均投资回报率显著低于非国有创业投资机构;(2)创业投资机构的资本规模与回报率呈显著负相关关系;(3)上海、深圳两地创业投资机构退出项目的回报率显著高于其他地区;(4)本土创业投资机构的从业时间、投资规模、投资周期、退出方式均与回报率没有显著相关关系。本文在此基础上提出了相关的政策建议。     

THE PUBLIC SECTOR PAY GAP IN FRANCE, GREAT BRITAIN AND ITALY

We investigate public–private pay determination using French, British and Italian microdata. While traditional methods focus on parametric methods to estimate the public sector pay gap, in this paper, we use both non-parametric (kernel) and quantile regression methods to analyze the distribution of wages across sectors. We show that the public–private (hourly) wage differential is sensitive to the choice of quantile and that the pattern of premia varies with both gender and skill. In all countries the public sector is found to pay more to low skilled workers with respect to the private sector, whilst the reverse is true for high skilled workers. When comparing results across countries, we find that where pay formation is more regulated (i.e. as in France and Italy) the public sector pay gap is smaller; whilst where market factors play a larger role in pay determination (i.e. as in Great Britain) the public sector pay gap is larger—particularly in the lower part of the wage distribution—and females are much better off in the public sector as compared to the private sector.     

科学与实证——一个基于“神经元经济学”的综述

诞生于20世纪90年代中晚期的神经元经济学(Neuroeconomics)是经济学的最新分支和经济学前沿研究的最新领域,它运用现代神经科学的范式、方法和技术工具分析人类的经济行为以及脑组织(主要是神经元及其相关的神经突触联结和神经网络)在人类决策过程中的功能、作用和机制,把经济学的实证研究提升到一个前所未有的高度,对经济学传统理论提出一系列意义重大的修正,从而为经济学的发展深化开拓了一个全新的空间。     

CONSUMPTION GROWTH ACCOUNTING

The methodology in this paper combines an input–output structural decomposition approach with the supply-side perspective of mainstream growth accounting. In explaining the intertemporal change in consumption per worker, three sets of effects are distinguished. First, contributions due to several types of technological changes are considered. Second, effects caused by changes in international trade are discerned. Third, composition effects that reflect structural shifts in demand (including changes in tastes) are quantified. As an empirical illustration, we analyze the developments in the U.K. between 1979 and 1990.     

机场博弈与中国起降费规制改革-一个合作博弈论评价

本文通过在机场博弈中使用的合作博弈论中两个成本分摊工具——Shapley值和Owen值,用厦门高崎机场2002至2005年(预计)的全年起降数据,计算了以合作博弈论为基础的机场起降费标准。本文将理论值与中国机场起降费用改革历程中的三个收费标准作出了比较,同时对民航总局提出的起降费上限改革进行了分析,并提出相应的政策建议。另外,本文还对即将在中国各大机场起降的最大型飞机A380的起降费用进行了理论上的估算。     

中国改革时期省际生产率增长变化的实证分析(1979-2001年)

中国经济的发展是否正在背离比较优势的原则?今后中国是否要加快经济增长模式的转变?该文试图通过对省际全要素生产率(TFP)及其组成部分的测算,从技术效率和技术进步这两个不同的方面来考察中国改革开放以来的TFP增长性质和近几年来的变化趋势,以便为相关政策讨论提供一些实证依据.我们的研究结果表明,中国经济增长在1978-1995年期间经历了一个TFP高增长期(为4.6%);而在1996-2001年期间出现低增长期(为0.6%),其变化的具体特征为:技术进步速度减慢、技术效率有所下降.
