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.     

Inequality,Redistribution, and the Financial Crisis: Evidence from Distributional National Accounts for Austria

In this paper, we provide novel findings regarding the distributional effects of the global financial and economic crisis and how redistribution operated during this time, using detailed data for Austria. We construct distributional national accounts for the period 2004–2016 by combining survey data, tabulated tax data, and detailed national accounts data. The comprehensive data set allows us to analyze the distribution of macroeconomic income growth across the income distribution and to explore the evolution of income inequality over time. Our results suggest that as the distribution of growth changed over time, this had considerable repercussions for inequality, which started to decline at the very beginning of the economic and financial crisis, but increased again after 2012. We find that capital income largely determined both the level and the dynamics of income inequality. Government spending was found to play a key role for redistributive effects across the income distribution. In particular, in-kind transfers redistributed pre-tax income to a large extent. Our results show further that individuals with lower educational levels and younger individuals faced negative growth in pre-tax income over the years and also benefited considerably from redistribution.     

间接税归宿的累退性与居民收入不平等

本文构建了间接税归宿的累退性与居民收入不平等关联的理论模型,该模型表明,间接税累退程度越高,居民收入越不平等。运用中国数据,估算累退性指标,本文发现,中国间接税具有累退性,并且增值税和消费税的累退性较强,营业税累退性稍弱,它们不同程度地恶化了居民收入不平等。本文最后提出了政策建议。     

个人所得税制度的收入分配效应——基于微观模拟的研究途径

本文提供了一个微观模拟模型,用于分析我国个人所得税制度的收入分配效应.模型通过收入调整、收入时化和税收制度实施更新微观个体的收入状态,通过对微观个体收入状态的统计估算税收制度的收入分配效应.应用吉林省城镇居民的微观数据,我们对个人所得税制度的收入分配效应进行了模拟.模拟结果表明:个人所得税制度的谩计基本满足居民之间和地区之间税负公平原则;尽管目前个人所得税制度的实施没有起到明显降低城镇居民收入差距的效果,但随着居民收入水平的持续增长和收入差距的不断扩大,税收制度调控居民收入分配的能力将不断增强.     

Income Underreporting and Tax Evasion in Italy: Estimates and Distributional Effects

The paper estimates the extent of evasion of personal income tax (PIT) in Italy by integrating two methods that the literature has previously applied separately. The consumption-based method introduced by Pissarides and Weber (1989) is used to estimate misreporting of income in micro data collected in the household IT-SILC survey. We adopt an econometric specification close in spirit to that of Feldman and Slemrod (2007), which allows us to estimate income misreporting at different rates for different income sources. The misreporting estimates are then used in the discrepancy method to correct the incomes compared with administrative registered data. The comparison provides new estimates of evasion of personal income tax by type of income, region and income class. The estimates are used to improve microsimulation analyses of the distributional impact of tax evasion.     

The effects of progressive income taxation on job turnover

We examine whether the level of the income tax rate and the convexity of the income tax schedule affect job mobility, as measured by moving to a better job. While the predicted effect of the level of the tax rate is ambiguous, we predict that an increase in the convexity of the tax schedule decreases job search activity by taxing away some of the benefits of a successful job search. Using data from the Panel Study of Income Dynamics, we estimate that both higher tax rates and increased tax rate progressivity decrease the probability that a head of household will move to a better job during the coming year. Our estimates imply that a five-percentage-point reduction in the marginal tax rate increases the average probability of moving to a better job by 0.79 percentage points (a 8.0% increase in the turnover propensity) and that a one-standard-deviation decrease in our measure of tax progressivity would increase this probability by 0.86 percentage points (a 8.7% increase in the turnover propensity). This estimate is robust to sensitivity analysis examining the importance of different sources of identification and variation in estimated effects across subgroups in the population. Our estimated importance of tax policy for job turnover suggests a potential role in explaining the responsiveness of taxable income to marginal tax rates.     

Understanding Rising Income Inequality in Germany, 1999/2000–2005/2006

We examine the factors behind rising income inequality in Europe's most populous economy. From 1999/2000 to 2005/2006, Germany experienced an unprecedented rise in net equivalized income inequality and poverty. At the same time, unemployment rose to record levels, part‐time and marginal part‐time work grew, and there was evidence for a widening distribution of labor incomes. Other factors that possibly contributed to the rise in income inequality were changes in the tax and transfer system, changes in the household structure (in particular the rising share of single parent households), and changes in other socio‐economic characteristics (e.g., age or education). We address the question of which factors were the main drivers of the observed inequality increase. Our results suggest that the largest part of the increase was due to increasing inequality in labor incomes, but that changes in employment outcomes and changes in the tax system also contributed considerable shares. By contrast, changes in household structures and household characteristics, as well as changes in the transfer system only seem to have played a minor role.     

Tax Competition and the Distribution of Income*

In this paper, we provide a two-country, two-class model of asymmetric capital tax competition. We show formally that poor people living in small countries can benefit from capital tax competition and therefore they are in favor of it. In order to benefit from capital inflow from larger countries, poor people in smaller countries accept less within-country income redistribution. As a consequence, between-country income inequality is increased by tax competition.     

‘Flattening’ tax evasion?

We analyze the response of tax evasion to the introduction of a flat tax in several transition economies. Using a novel estimator based on household level data, we show that in most of the countries studied there was no discernible effect on the measured size of unreported income following a flat tax reform. This may imply that decreases in marginal tax rates may frequently have been accompanied by a parallel deterioration in attitudes towards public services and the government in general. The countries that show a response to the flat tax reform appear to be those where satisfaction with government services increased.     

城镇居民财产性收入不平等研究

本文利用《中国城市（镇）生活与价格年鉴》提供的数据,分析了财产性收入在影响我国城镇居民总收入不平等中所处的地位和具有的特点。在此基础上,本文进一步研究了财产性收入内部的不平等和各部分对总体不平等的贡献率,以及个人所得税在财产性收入调节中的作用。研究表明,目前我国城镇居民财产性收入增长迅速,并且对总收入不平等的贡献率呈明显的上升趋势。此外,财产性收入差距不断扩大,其内部不平等情况十分严重,目前个人所得税对财产性收入不平等的调节效果不明显,今后仍有很大的调控空间。     

城镇家庭收入差异研究——基于2005-2009年安徽省城镇家庭月度住户调查数据的分析

本文以经典的经济增长理论为基础，结合中等收入国家的特点，提出如下理论假设：通胀所造成的家庭福利损失会影响中等收入国家宏观经济的发展，进而推动相关国家陷入“中等收入陷阱”。而后通过FGLS、差分GMM，以及系统GMM的方法对陷入“中等收入陷阱”的典型国家进行回归分析。分析结果表明，在控制了基础设施、债务水平、技术创新以及储蓄率这些影响因素之后，通胀对上述国家人均GDP增长率均有显著的负向影响，即使是在年均通胀率只有514%的东亚国家组，通胀对人均GDP增长率的平均影响也达到了123个百分点～221个百分点，影响比重达到了27%～48%。所以，我们应该加强对通胀的调控，以确保我国经济能够持续健康地发展。     

税收、收入不平等和内生经济增长

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。     

间接税归宿对城乡居民收入分配影响研究

使用全国城乡家庭消费和收入微观数据考察间接税对于城乡收入差距和收入分配的影响发现:平均来看,全国居民负担的税收占收入的比例是10.6%;不论在全国范围来看还是分别在城乡内部来看,间接税负担都呈现累退:低收入的负担率高于高收入的负担率。在城乡之间,城镇居民的税收负担率高于农村居民的税收负担率。间接税增加了城乡内部不平等,降低了城乡之间的不平等。间接税主要对低收入群体影响较大,略微恶化了整体收入不平等。     

Income distribution and redistribution through taxation: An international comparison

Income tax progressivity is studied with Generalized Entropy measures of inequality. Luxembourg Income Study data sets for nine countries are used for international comparison and analysis. progressivity indices are generated by using the Generalized Entropy family as well as Atkinson measures. We further our understanding by examining pre-tax and post-tax measures of inequality based respectively on gross and disposable household incomes. The decomposition property is shown to be desirable for enhancing our knowledge of income inequality and the redistributive effect of income taxes. Thus decomposition based on family size and number of earners is conducted. We learn that countries vary in their emphasis regarding redistributive effects of income taxes.     

收入不平等与家庭借贷行为*——家庭为追求社会地位而借贷的动机真的存在吗

本文利用中国家庭金融调查(CHFS)2011年度的调查数据,考察了收入不平等对家庭借贷行为的影响,并验证了家庭是否存在为追求社会地位而借贷的动机。研究表明：（1）收入不平等并不是影响家庭是否借贷的主要因素,但是对家庭的负债规模存在十分显著的抑制作用;（2）收入不平等的扩大并不会促使中低收入家庭寻求借贷或提升家庭负债规模,我国家庭并不存在为了追求更高的社会地位而进行借贷的动机;（3）收入不平等的扩大有利于高收入家庭获得更多的正规金融借贷,中低收入家庭则会较多地依赖于非正规金融借贷;（4）户主的人口统计学特征、家庭经济特征以及家庭所处地区特征均是影响家庭借贷行为的重要因素,在正规金融和非正规金融市场上,影响家庭借贷行为的因素存在较明显的差异。     

Numerical simulation on property tax reform: evidence from China

This article analyses the property tax reform in China in a computable general equilibrium model that recognizes the interaction between and among housing markets in different provinces and macroeconomic development. Using real data in 2010, we present the benchmark equilibrium for reference property and income tax rates. Then, we examine different property and income tax policies and make a comparison of their production, consumption, welfare and national income. We find that the implementation of property tax would decrease the house production at the expense of welfare in taxed area. The expansion of the taxed regions may increase the total social welfare and national income. Even though property tax policy may not be able to change the income distribution in China, increasing income tax rate could narrow the income disparity. Finally, this article shows the reliability of the conclusions when sensitivity analysis on optimal condition of equilibrium computation is performed under varied property tax policy.     

The role of labour demand elasticities in tax incidence analysis with heterogeneous labour

Whether labour bears full burden of household level income and consumption taxes ultimately depends on the degree of substitutability among different types of labour in production. We find more variation in incidence patterns across households with less than perfectly substitutable heterogeneous labour than with perfectly substitutable homogeneous labour in production. This finding is based on results obtained from homogeneous and heterogeneous labour general equilibrium tax models calibrated to decile level income and consumption distribution data of UK households for the year 1994. We use labour supply elasticities implied by the substitution elasticity in households' utility functions and derive labour demand elasticities from the substitution elasticity in the production function.

HOUSEHOLDS, STANDARD OF LIVING, AND INEQUALITY

The standard of living of individuals does not depend so much on the income they themselves earn as on the total income of the household to which they belong and how the household organizes the use of its income. It is important to develop methods of income analysis which incorporate the household factor. In income distribution analysis, it is now common to take into consideration household size and composition in relative interpretations of income levels. In this paper it is suggested that the same methodology can be used for the purpose of absolute interpretations of income levels. The result is an alternative to per capita measures of standard of living which is sensitive not only to national income and population size, but also to household formation. This approach is applied to Norwegian data for the period from 1970 to 1986 as to trends in the average standard of living and standard of living inequality, and the redistributive impact of transfer and tax policies.     

Employment polarisation and inequality in the UK and Hungary

This paper uses household budget survey microdata to explorethe growth in household income inequality in Hungary in theperiod 1987–1995, and compares it with inequality in theUK in 1995–96. Decomposition of inequality according toboth household characteristics and income sources shows that,while inequality did grow rapidly in Hungary over the earlyTransition period, several factors prevented its growth to higherlevels. One of these factors, the distribution of employmentand earnings between households, is explored in some detail.While there was considerable polarisation between householdswith and without employed members in the UK in 1995–96,this was less of a feature in Hungary, in spite of a massivewithdrawal of men and women from the labour market between 1987and 1995. Rather, a narrowing of the gender pay gap and a continuedhigh level of female participation in employment appears tohave ensured that, even as earnings inequality in Hungary increasedto the extent that it surpassed earnings inequality in the UK,the distribution of household earnings, and the distributionof household incomes, remained more equal in Hungary.     

An assessment of the impact of tax incentives relative to socio-economic characteristics on charitable giving in Canada

This research examines the effectiveness of the Canadian tax incentive system for charitable giving while attempting to deal with two persistent methodological problems in past research. The Heckman selection model and the ordered probit model are used to examine the Canadian tax incentive system with 2010 survey data. The results imply that the effect of the tax credit systematically increases with an increase in donation expenditure suggesting that the higher tax credit for larger donations is more effective than the lower tax credit for smaller donations. While the results suggest that the current tax policy is effective, socio-economic characteristics, such as wealth, household income, and university education, appear to have a greater impact on donations.
