税收、收入不平等和内生经济增长 总被引:1,自引:0,他引:1
企业家(通过金融中介)从家庭借贷来支撑创新。二者在企业家的努力不为外人所见的情形下双方签订信用合同分享创新带来的垄断利润(即蛋糕)。两个有代表性经济人(企业家和家庭)的存在允许人们在内生经济增长模型里研究收入不平等。本文研究发现,企业家分配份额的增加一开始会提升增长速度,但是过了一定值后会拉低增长速度;而该份额的增加一直拉大企业家和工人间的收入差距。所以降低企业家获得的蛋糕的份额的分配改革可缩小收入差距。提高企业家来自创新的收入的税率将降低他们的努力程度,从而降低增长速度,但是该税率的提高有助于降低收入不平等程度。存款收入的税率提高尽管不会改变企业家的努力程度,但是也会降低经济增长速度,而且不会降低收入不平等(如果工人有一定比例的存款)。对于劳动收入(工人工资)的税率增加会加剧工人和企业家间的收入不平等,但对经济增长速度没有影响。 相似文献

在相关文献的基础上,选取财政支持效率评价作为突破口,研究了我国科技重大专项管理路径。分析重大专项财政投入现状发现,资金使用情况良好,支出结构基本合理,多元化投入机制逐渐建立,管理制度基本建立。同时,通过DEA和Malmquist模型评估了决策单元的综合效率值和动态效率值,结果表明,财政支持重大专项发展过程中的资源配置效率并没有实现最优。但是,通过技术创新、资源配置、规模效率等途径优化重大专项管理的效果已初步显现。效率较为低下的表象为科研活动价值补偿不足,制约因素包括:事权缺乏清晰界定且事权与支出责任不匹配、组织管理体制有待完善、实施模式缺乏清晰判断。最后,提出了建议,包括不断完善重大专项财政投入及其管理、匹配科技重大专项事权与支出责任、健全重大专项实施机制、优化管理架构。 相似文献

运用相对收入流动指标及绝对收入流动指标对1989—2004年间各时期城市与农村家庭的收入流动性进行分析,我们发现:1989—2004年间各时期内城市与农村家庭的平均收入增长速度从低收入组到高收入组逐层递减。城乡居民收入流动性都处于较高的水平,与城市相比较,农村贫穷阶层家庭的收入向上的流动性要大于城市的贫穷家庭。低收入阶层向上的收入流动以及高收入阶层向下的收入流动使得1989—2004年间各时期城市与农村家庭的长期收入差距得到了缓解。 相似文献

Using labor supply responses from 10,560 urban Chinese workers, two-stage least squares estimations identify positive compensated wage effects and negative income effects that are, for the most part, statistically significant. The gross wage effects are mostly positive but they indicate relatively low uncompensated labor supply elasticities. The compensated wage effects are much larger; these may be important in assessing the labor market consequences of reform policies that monetize non-pecuniary benefits. The significance of labor supply responses depends on individual responsibilities within the family; the effects are largest for women and non-household heads.

人口流动性、公共收入与支出--户籍制度变迁动因分析 总被引:19,自引:0,他引:19
本文分析了人口流动性的内生决定 ,以此解释中国户籍管理政策变迁的动因。文章表明 ,分权框架下的区际竞争将推动政府降低人口流动成本。一般而言 ,集权 ①框架下的最优流动性水平普遍低于分权框架下的流动性水平。与我国近 2 0年来户籍政策变化相一致的是 ,跨区劳动力配置需求的上升增加了户籍管制的效率损失成本 ,将推动人口流动成本下降。我们认为 ,除了协调地方公共品供给外部性、限制地区间税收竞争以最大化税收收入这两个基本原因之外 ,我国户籍管制的另一个特殊原因是便于执行地区差别政策。而设置流动成本的效率性取决于政府目标与社会福利最大化的一致性程度。 相似文献

As indicators of social welfare, the incidence of inequality and poverty is of ongoing concern to policy makers and researchers alike. Of particular interest are the changes in inequality and poverty over time, which are typically assessed through the estimation of income distributions. From this, income inequality and poverty measures, along with their differences and standard errors, can be derived and compared. With panel data becoming more frequently used to make such comparisons, traditional methods which treat income distributions from different years independently and estimate them on a univariate basis, fail to capture the dependence inherent in a sample taken from a panel study. Consequently, parameter estimates are likely to be less efficient, and the standard errors for between-year differences in various inequality and poverty measures will be incorrect. This paper addresses the issue of sample dependence by suggesting a number of bivariate distributions, with Singh–Maddala or Dagum marginals, for a partially dependent sample of household income for two years. Specifically, the distributions considered are the bivariate Singh–Maddala distribution, proposed by Takahasi (1965), and bivariate distributions belonging to the copula class of multivariate distributions, which are an increasingly popular approach to modelling joint distributions. Each bivariate income distribution is estimated via full information maximum likelihood using data from the Household, Income and Labour Dynamics in Australia (HILDA) Survey for 2001 and 2005. Parameter estimates for each bivariate income distribution are used to obtain values for mean income and modal income, the Gini inequality coefficient and the headcount ratio poverty measure, along with their differences, enabling the assessment of changes in such measures over time. In addition, the standard errors of each summary measure and their differences, which are of particular interest in this analysis, are calculated using the delta method. 相似文献

Information and communication technology (ICT) products have undergone rapid technical change. Where quality improvements occur, they should be reflected in official price and quantity indices, otherwise there is a tendency to over-estimate price movements and under-estimate volume changes of ICT products. Statistical offices deal with this issue but the degree and nature of quality-adjustment of price indices of ICT products varies considerably between OECD countries. The present study simulates measurement effects on key economic variables (real output, private final consumption, government expenditure, investment, exports and imports) and productivity, under the assumption that the price indices of ICT products are fully quality-adjusted. The paper draws on a large selection of empirical studies to identify differences between quality-adjusted and unadjusted price changes and uses detailed information from input-output tables to assess their weights in final demand. Effects on GDP and its components are quantified for five selected OECD countries. 相似文献

Abstract The purpose of the present paper is to examine the effects of taxation on income distribution in a model with efficiency wages and involuntary unemployment. Central to our efficiency-wage model is the hypothesis that firms set wages above market-clearing levels, whenever the productivity of labor depends on the real wage paid by the firm, and unemployment. Within a two sector general equilibrium model we study the incidence of factor and commodity taxes on income distribution, and unemployment. Our findings differ substantially from those derived by the traditional neoclassical analysis, originally developed by Harberger, and as it has been extended by several authors. 相似文献
