THE INCOME REDISTRIBUTION EFFECT OF CHINA'S PERSONAL INCOME TAX: WHAT THE MICRO‐DATA SAY

This article uses continuous micro‐level data to investigate the income redistribution effect of the personal income tax (PIT) in China beginning in 1997. We find that the average tax rate plays a larger role in determining the income redistribution effect of PIT than tax progressivity does. Although tax progressivity decreased as a result of rising personal incomes and a constant PIT policy prior to 2005, the income redistribution effect of the PIT improved as a result of the higher average tax rate. The tax reform beginning in 2006 increased tax progressivity while decreasing the average tax rate, thereby weakening the income redistribution effect of the PIT. Further analysis indicates that the middle‐income group was the only net loser before 2005, but it benefited from the PIT policy reform. A cross‐country comparison shows that China has a lower PIT burden and higher progressivity than developed countries; in fact, China's levels of progressivity and tax burden are similar to those of Latin American countries.

Flat tax? Maybe not a bad idea after all

This work studies the actual degree of progressivity in the Italian tax and transfer system and examines possible reforms towards the optimum. It analyzes the distribution of personal income and effective tax rates across the Italian population, computing income and tax liabilities from survey data, and studies the optimal level of progressivity. To this end, it uses a model developed in Heathcote et al. (2017) with heterogeneous agents where skill investment and labor supply are endogenous and the government provides a public good under a balanced budget. All the main tradeoffs that shape optimal progressivity appear: the presence of inequality in initial conditions and imperfect private insurance push for positive progressivity, whereas labor supply and skill investment call for regressivity. The model suggests a drastic reduction in progressivity under both the baseline and the alternative specifications. In particular, it calls for substantial reductions in marginal tax rates above approximately 0.25 times the mean income along with increased tax rates at the lower end of the income distribution. These reforms may be approximated by a flat tax at 29% under the baseline and at 32.5% under the alternative specification, holding the required positive level of progressivity constant.     

WHO PAYS NO TAX? THE DECLINING FRACTION PAYING INCOME TAXES AND INCREASING TAX PROGRESSIVITY

Using federal individual income tax data, this paper presents the first long‐run estimates of the fraction paying no income tax. Between 1985 and 2015, the fraction of working age adults paying no tax increased from 20% to 36%. A decomposition shows that almost all of this increase resulted from changes in tax policy, especially from more generous tax credits. Increasing tax progressivity over the last three decades also resulted from more generous tax credits. The substantial federal tax changes enacted in 2017 are forecasted to temporarily increase both the fraction paying no tax and individual income tax progressivity. (JEL H22, H24, H31)     

个人所得税的累进性与再分配效应——以湖北省为例

以湖北省城镇调查数据为分析对象,以指数为工具,本文实证考察了我国个人所得税的累进性及再分配效应。得到的结论是我国个人所得税再分配效应很弱,但其原因并不在于税收的实际累进性小,而在于个人所得税的平均税率低,税收规模很小。同时,在各类收入中,工资性收入的个人所得税累进性很强,经营性收入及财产性收入的个人所得税累进性较差,甚至出现累退性。提高个人所得税规模、加强对经营性收入及财产性收入的税收征管、以家庭为单位征收是个人所得税进一步改革的方向。     

Are Progressive Income Taxes Stabilizing?

We assess the stabilizing effect of progressive income taxes in a monetary economy with constant returns to scale. It is shown that tax progressivity reduces, in parameter space, the likelihood of local indeterminacy, sunspots and cycles. However, considering plausibly low levels of tax progressivity does not ensure saddle‐point stability and preserves as robust the occurrence of sunspot equilibria and endogenous cycles. It turns out that increasing progressivity, through its impact on after‐tax income, makes labor supply more inelastic. However, even when large, tax progressivity does not neutralize the effects of expected inflation on current labor supply which may lead to expectation‐driven business fluctuations.     

Decomposable measures of income tax progressivity

A class of decomposable income tax progressivity indices is defined by using a family of generalized entropy measures. For demonstration, changes in income tax progressivity in the United States are studied over time.     

Personal income tax progressivity and output volatility: Evidence from OECD countries

This paper investigates empirically the effect of personal income tax progressivity on output volatility using macro data from a sample of OECD countries over the period 1982–2009. Our measure of progressivity is based on the difference between the marginal and the average personal income tax rate for the average production worker. We find supportive empirical evidence for the hypothesis that higher personal income tax progressivity leads to lower output volatility. This effect comes in addition to the stabilizing impact of government size and it is equally important in economic terms. All other factors constant, countries with more progressive personal income tax systems seem to benefit from stronger automatic stabilizers.     

The Austrian income tax tariff, 1955–2006

Using official statistics and tax laws, we outline and discuss the evolution of the personal income tax in Austria since the beginning of the Second Republic in 1955. Focusing on the tax tariff and its progressivity properties, we identify a period of high (and increasing) progressivity before 1989, followed by a period of diminished progressivity since 1989. While still being a powerful revenue instrument, the Austrian income tax seems to have lost both redistributive impact and political allure.

Optimal tax progressivity in unionised labour markets: What are the driving forces?

In labour markets with collective wage bargaining higher progressivity of the labour income tax creates a trade-off. On the one hand, wages are lowered and unemployment decreases, on the other hand, the individual labour supply decision is distorted at the hours-of-work margin. The optimal level of tax progressivity within this trade-off is determined using a numerical general equilibrium model with imperfect competition on the goods market, collective wage bargaining and a labour-supply module calibrated to empirically plausible elasticity values. The model is calibrated to macroeconomic and institutional parameters of both the OECD average and a number of individual OECD countries. In most cases the optimal degree of tax progressivity is below the actual level. A decomposition approach shows that the optimal level is increased by high unemployment and by the general tax level.     

PROGRESSIVITY AND REDISTRIBUTION IN NON‐REVENUE NEUTRAL TAX REFORMS: THE LEVEL AND DISTANCE EFFECTS

Kakwani and Reynolds–Smolensky indices are used in the literature to measure the progressivity and redistributive capacity of taxes. These indices may, however, show some limits when used to make normative assessments about non‐revenue neutral tax reforms. Two approaches have traditionally been taken to overcome this problem. The first of these consists of comparing after‐tax income distributions through generalized Lorenz (concentration) curves. The second approach is based on the decomposition of changes in the Reynolds–Smolensky index into changes in the average tax rate and variations in progressivity. Nonetheless, this decomposition between the average tax rate and progressivity may be further exploited to obtain some information that can be relevant to assess tax reforms. The main aim of this study is to draw up some indicators that can be useful to quantify the effects of non‐revenue neutral tax reforms. These indicators are used to investigate the last personal income tax reforms that have taken place in Spain.     

Progressive Taxation and Wage Setting: Some Evidence for Denmark

The proposition that a progressive tax system contributes to wage moderation is studied using Danish earnings data disaggregated by occupation, gender and earnings level. Our main conclusions are that income-tax progression affects wage setting, but whether it moderates or exaggerates wage pressure is income dependent. An increase in progressivity reduces the pre-tax earnings of middle-income workers (manual male workers and moderate income earners among both male and female non-manual workers). The reverse is found for high-income earners (non-manual male workers), in that an increase in progressivity tends to raise pre-tax earnings. Finally, there is no significant effect of tax progressivity on the wages of low-income earners.

TAXES AND ENTREPRENEURSHIP IN OECD COUNTRIES

I examine how taxes and tax progressivity affect two different types of entrepreneurship—established business ownership and nascent entrepreneurship—in a large group of Organization for Economic Co‐operation and Development countries, using 2000–2009 macro‐level Global Entrepreneurship Monitor data. Empirical evidence from Arellano‐Bond generalized method of moments estimation suggests that higher tax progressivity exerts a negative influence on nascent enterprises but appears to have no impact on established business ownership. Changes in marginal and average tax rates are found to have no significant influence on either type of entrepreneurship. The most important contribution of the article is the comparison of tax impacts on actual and nascent entrepreneurship rates. (JEL H24, H29, M13, M19)     

2011年个人所得税改革的收入再分配效应

本文考察2011年9月1日实施的个人所得税改革的收入再分配效应。根据目前我国分项课征的个人所得税征管模式,本文推导出税收的收入再分配效应指数按收入构成的分解方法。根据该分解方法的主要分析结果可概括为两点:其一,平均税率的高低是个税收入分配效应大小的主要决定因素,累进性则是次要的。由于平均税率的降低,本次税收改革弱化了本来就十分微弱的个人所得税的收入分配效应。其二,我国个人所得税整体累进性指数随工资薪金所得费用扣除的提高呈倒U型。十分巧合的是,本次改革确定的3500元免征额正好处于倒U型的最大值,超过3500元的费用扣除反而会削弱我国个税的累进性。     

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。     

Four Levers of Redistribution: The Impact of Tax and Transfer Systems on Inequality Reduction

We use harmonized survey data from the Luxembourg Income Study to assess the redistributive impact of taxes and transfers across 22 OECD countries over the 1999–2016 period. After imputing missing tax data (employer social-security contributions), we measure the reduction in income inequality from four key levers of tax and transfer systems: the average tax rate, tax progressivity, the average transfer rate, and transfer targeting. Our methodological improvements produce the following results. First, tax redistribution dominates transfer redistribution (excluding pensions) in most countries. Second, targeting explains very little of the cross-country variation in inequality reduction. In contrast, both tax progressivity and the average tax rate have large impacts on redistribution. Last, there seem to be political tradeoffs: high average tax rates are not found together with highly progressive tax systems.     

Lifetime versus Annual Tax‐and‐Transfer Progressivity: Sweden, 1968–2009

In this paper, we analyze the evolution of tax‐and‐transfer progressivity in Sweden over both annual and lifetime horizons. Using a rich micro panel covering the period 1968–2009, we calculate tax rates over a cohort's entire working life cycle. Our main finding is that taxes are considerably less progressive over the lifetime than in any single year. Social insurance transfers to transitory low‐income earners account for most of this result. We offer a number of robustness checks of the measurement of lifetime incomes and progressivity, but none of them changes our overall findings.     

EFFECTS OF PERSONAL INCOME TAX ON INCOME DISTRIBUTION: EXAMPLE FROM BULGARIA

This study utilizes the 1992 Bulgarian household budget survey to analyze the distribution of income and income tax burden. Results indicate that the country is characterized by low income inequality, though this is changing rapidly. The findings also show that the present income tax system is progressive and that the urban sector pays much more relative to its income. Despite a steeply graduated statutory tax rate schedule, effective progression is rather modest, indicating significant tax evasion. However, one must view the results of progressivity and urban bias cautiously. As in-kind income becomes monetized and as the economy becomes more market-oriented, both progressivity and urban/rural differences will wane over time.     

Tax Reform and Progressivity

The established theory of tax progressivity cannot handle basic tax reform questions, such as whether an increase in personal allowances makes the tax system more progressive, because the core results assume that tax liability is never zero. This paper generalises the core theory to allow for zero tax payments, and applies the new framework to the analysis of allowances, income-related deductions and tax credits. Log concavity of the tax schedule—a property quite distinct from any existing notion of progressivity—emerges as the critical determinant of whether the distribution of the tax burden becomes more progressive as allowances are increased.     

Openness, income-tax progressivity, and inflation

This paper considers a model of an open economy in which the degree of income-tax progressivity influences the interaction among openness, central bank independence, and the inflation rate. Our model suggests that an increase in the progressivity of the tax system induces a smaller response in real output to a change in the price level. This implies that increased income-tax progressivity reduces the equilibrium inflation rate and that the effect of increased income-tax progressivity on inflation is smaller when the central bank places a higher weight on inflation or when there is greater openness. Examination of cross-country inflation data provides empirical support for these key predictions.     

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.
