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。     

Income inequality, democracy and growth reconsidered

In: Cukierman, A., Hercowitz, Z., Leiderman, L. (Eds.), Political Economy, Growth, and Business Cycles. MIT Press, Cambridge, MA, pp. 23–50; Alesina, A., Rodrik, D., 1994. Distributive politics and economic growth, Q. J. Econ. 109, 465–490) have argued that income inequality reduces economic growth rates among democracies because it promotes distributional struggles. In this paper I question the supportive evidence for a number of reasons. Measures of income distribution and democracy are unreliable and permit only very tentative conclusions. Changes in data sources or recoding of some influential cases affect results. It is questionable whether equality effects on growth apply only within democracies, as a median voter interpretation of this relationship should make one expect. The general idea that distributional struggle hurts the growth prospects of nations, however, receives some empirical support.     

收入和流动性风险约束下家庭金融资产选择的实证研究

本文采用SCF数据,运用TOBIT模型从实证的角度研究收入风险和流动性约束对投资者资产选择的影响。研究结果表明：控制其他变量的影响之后，收入风险的增加会使得投资者降低对风险资产的需求．预期未来流动性的约束也减少投资者的风险资产投资比例。接着本文采用分类回归及将风险资产投资比例概念由狭义转变为广义，得到的结论都和前面的研究一致。最后．本文采用迭代LAD回归技术所得到的结果也证明了本模型的结论具有稳健性。     

Will China's WTO accession worsen farm household incomes?

Many fear China's accession to the World Trade Organization (WTO) will impoverish its farmers via greater import competition in its agricultural markets. We explore that possibility bearing in mind that, even if producer prices of some (land-intensive) farm products fall, prices of other (labor-intensive) farm and nonfarm products could rise. New estimates, from the global, economy-wide numerical simulation model known as Global Trade Analysis Project (GTAP), of the likely changes in agricultural and other product prices as a result of WTO accession, are drawn on to examine empirically the real income implications of China's WTO accession. The results suggest farm–nonfarm income inequality may well rise within China but rural–urban income inequality need not. The article concludes with some policy suggestions for alleviating any pockets of farm household poverty that may emerge as a result of WTO accession.     

The Effect of China＇s Individual Income Tax on Income Distribution： Based on Different Perspectives and Data from Different Sources

本文以税前后收入份额差距、平均税率作为指标,分别从纳税人与收入的角度对2000—2009年间我国个人所得税的再分配效应与累进性进行了考察。基于公开统计数据的计算表明：就纳税人角度而言,个人所得税在收入分配方面发挥了明显的正效应,而且还呈现出不断加强的累进性。基于学者王小鲁测算的数据所进行的计算则表明：个人所得税的再分配效应与累进性相对较弱,且从收入角度来看,个人所得税反而表现出累退性。有关结论的差异提示,改善征管与统计状况是转向分类综合模式个税,加强个税再分配功能的必要条件。

Boom, bust, and the poor: Poverty dynamics in the Middle East and North Africa, 1970–1999

This paper analyzes changes in poverty and inequality in the Middle East and North Africa. It finds that the structural relationship between poverty reduction, income growth and distribution is the same for MENA and other developing economies. Prior to 1985 rapid growth sharply reduced poverty. After 1985, despite very low income growth, a rising share of income accruing to the lowest quintile meant that the average income of the poor rose more rapidly than that of the non-poor. These unusual poverty dynamics were primarily due to international migration. Remittances both increased per capita incomes in labor exporting countries and increased the share of income accruing to the poor.
