Does Work Always Pay in Germany?

Abstract. Income redistribution in Germany is the result of a combination of several redistribution instruments: there is a complex income tax law, different obligatory social insurances and supplementary benefits. This paper estimates income redistribution by quantile regression, using German EVS data. Two results are obtained: income after redistribution does not always increase in line with income before redistribution, i.e. for people with a low income before redistribution, it does not make sense to increase their efforts, since more work means less earnings. Further, an increasing redistribution rate for higher incomes is not always observable from the data.     

The public and private provision of pure public goods and the distortionary effects of income taxation: a political economy approach

Abstract .  A pure public good is provided by the government and the voluntary contributions of two types of households. The government finances its contribution by means of income taxation. The latter has distortionary effects. A third type of household never makes contributions. We analyse the effects of changes in the income tax rate on (a) the provision of the public good, (b) the private contributions of the households, and (c) changes in the distribution of income and welfare between contributing and non-contributing households. We derive a simple and testable condition under which the lowering of the income tax entails a Pareto improvement.     

个人所得税的累进性改革问题——基于单一个人所得税改革的前景分析

按照与市场经济运行机制相适应的要求,对个人所得税制度进行一次比较彻底变革,除了应在税基方面建立起分类与综合相结合的个人所得税制以外,一个核心的问题就是重构个人所得税的税率结构。我国可实行分两步走的渐进改革方案和一步到位的单一税改革方案。改革后的个人所得税制应该是按照递增的平均税率但又是递减的边际税率对全部所得课税这两方面的结合。中国具备实施单一税改革的政治、财政与技术条件,目前改革的时机也是合适的。     

HUMAN CAPITAL FORMATION AND TAX EVASION

A strictly risk‐averse individual with an exogenous gross income in period one can acquire human capital in the same period and evade taxes. Period‐two income rises with educational investments in period one and can also be hidden from tax authorities. It is shown that a greater tax deductibility of educational investments and higher individual ability induce a positive correlation between tax evasion and educational investments in period two, whereas the relationship in period one is ambiguous. These theoretical predictions can explain diverse empirical findings on the correlation between education and tax evasion.     

中国个人所得税的性质及其效果分析

以工资薪金税收为主体的个人所得税是一种消费者税。由于起征额的存在,个人所得税并不是一种完全的所得税,而是一种个人收入调节税。基于消费者税的理论基础,提出了关于中国代表性居民纳税人的理论平均税负的一个简单模型,以及一个关于中国个人所得税对全部税收的贡献率的理论计算公式。中国个人所得税改革应着眼于如何改善工薪所得税的累进性,增强税收的收入再分配职能,相对提高低收入劳动者的实际报酬。为此,应将个人所得税易名为个人收入调节税,减少税率档次,提高免征额。     

中国卫生筹资的再分配效应

利用2006年中国健康与营养调查(CHNS)数据和类似于税收再分配的分解方法,将卫生筹资的再分配效应分为三部分:累进效应、水平平等效应和再排序效应。卫生筹资增加了收入不平等,表现出了亲富人的再分配,主要原因在于水平不平等和再排序效应,如果相同收入的人群进行相同的卫生支付,再分配效应将会降低64%,另一原因在于卫生筹资系统的累退性。在同为从穷人到富人的再分配中,农村卫生筹资亲富人的再分配程度高于城市;农村卫生筹资的累退程度大于城市;农村卫生筹资的水平不平等小于城市。     

Labor or consumption taxes? An application with a dynamic general equilibrium model with heterogeneous agents

This study analyzes the effects of tax reform that shifts tax burden from labor to consumption. In this context, I also deal with the issue of progressivity. Even though this kind of tax policy change has recently gained popularity, its positive effects are debatable while the offsetting effect of a consumption tax on labor supply makes the net output change rather ambiguous. I examine these effects using a dynamic general equilibrium model with heterogeneous agents. The model is calibrated to fit certain characteristics of the Finnish economy. In addition to output and employment effects, I study the tax reform's effect on income and wealth distribution. First, I find that eliminating progressivity in labor taxation increases output via increase in capital accumulation that comes, however, in expense of slightly more inequality. Then, tax reform that replaces progressive labor taxes with a flat-rate consumption tax leads to a significant rise in capital accumulation, a negligible change in labor supply and gross labor income distribution, but a relatively considerable increase in wealth concentration.     

Optimal environmental taxes and standards: Implications of the materials balance

This paper investigates the implications of the materials balance for optimal environmental policy. We find that neglecting the materials-emissions relationship - as is common in models of optimal environmental regulation - implies biases, whose sign depends on the regulatory instrument chosen. When emissions are regulated through an emission tax, the seemingly optimal tax is too high. When regulation proceeds through the use of an emission standard, the seemingly optimal standard is too lax.     

我国流转税收入分配效应的实证分析

对2002-2009年我国增值税、消费税和营业税在不同收入户城镇居民间的分布及其对收入分配的影响进行综合分析,可得出三点基本判断:一是增值税表现出明显的累退性,且累退的症结在于适用低税率商品的消费需求缺乏收入弹性;二是不同消费品的调节效果相互抵消,消费税对收入分配的整体影响并不明显,但呈逐步向累进性发展的趋势;三是营业税表现出稳定的累进性。全部流转税呈现非常轻微的累退性,决定流转税收入调节效果的主导因素是消费品的需求收入弹性。通过恰当选择课税对象和实施差别税率,特定流转税完全有可能起到缩小收入分配差距的作用。
