Income inequality and economic growth

Despite the extensive existing literature on income inequality and economic growth, there remains considerable disagreement on the effect of inequality on economic growth. Existing literatures find either a positive or a negative relationship. In this paper, we attempt to theoretically examine that relationship with a stochastic optimal growth model. We make the disagreement clear within a single model. We conclude (i) that both are possible – that is, higher inequality can retard growth in the early stage of economic development, and can encourage growth in a near steady state, (ii) that income redistribution by high income tax does not always reduce income inequality. Income inequality can be reduced by higher income tax in a near steady state, but it cannot be reduced in the early stage of economic development, and (iii) that two government polices – rapid economic growth and low income inequality – can be achieved by low income tax in the early stage of economic development, but both cannot be achieved simultaneously in a near steady state.     

国有单位工资结构及其就业规模变化的收入分配效应:1988—2007

本文使用1988年、1995年、2002年、2007年CHIP城镇入户调查数据考察国有单位工资结构及其就业规模变化的收入分配效应。为此,本文采用了分位数回归方法、以多重分位数回归为基础的Machado&Mata(2005)反事实分解方法及作者扩展了的方法。各结果表明:国有企业就业份额大幅度下降导致中国城镇工资收入差距显著下降;然而国有企业减员增效改革完成以后,国有企业工资高于非国有企业的幅度及其不合理部分大幅度上升,其结果是城镇工资收入差距扩大。     

如何缩小我国个人贫富差距

我国个人收入差距不断扩大,是国民收入初次分配和再分配制度存在缺陷造成的。只有深化分配制度改革,才能从根本上扭转这一趋势,最终更好地实现社会公平。     

财政收支对城乡收入差距影响的实证分析——以重庆市为例

财政政策为解决城乡收入差距提供了一种有效的途径。在财政收支与城乡收入相关理论的基础上,采取协整和误差修正模型分析了财政对重庆城乡收入差距的影响。从长期来看,财政支出有利于缩小城乡差距,而财政收入则会拉大城乡收入差距,均衡财政对改善城乡收入差距的效果不显著,这就要求政府在实施财政政策时要充分考虑财政收支对城乡收入差距的不同影响,优化财政收支结构,进而缩小城乡收入差距。     

城乡居民家庭收入流动与长期收入均等

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。     

Do Piketty and Saez Misstate Income Inequality? Critiquing the Critiques

A large body of literature points to sharply growing income inequality over the past half century. The Piketty and Saez dataset that measures income distribution provides empirical support for this claim. Our article evaluates three prominent criticisms of this dataset as well as the responses of Piketty and Saez to these criticisms. One key argument against using their dataset is that Piketty and Saez do not control for income shifting by top income earners in response to the Tax Reform Act of 1986 (TRA86) and thus overstate income inequality. In evaluating this criticism we find that a segment of their dataset likely understates income inequality; this is just the opposite of what critics assert. This implies that the Piketty–Saez dataset is a valuable resource for income inequality research and that scholars can use it to build more refined, accurate and insightful measures of income inequality.

Labor supply in urban China

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.

Minimum wage or negative income tax: why skilled workers may favor wage rigidities

In this article, we analyze the political choice of the extent and means of income redistribution between high and low-skilled workers. Redistributive tools encompass both fiscal transfers (a negative income tax) and a minimum wage requirement. We assume the use of fiscal instruments alone to be the first-best means of redistribution. We show that high-skilled workers may favor a second-best, minimum wage requirement because it increases unemployment, hence raising the marginal cost of redistribution, and creates a justification for them to moderate low-skilled workers’ claim for redistribution.
