Taxes,Tuition Fees,and Education for Pleasure

The fact that education provides both a productive and a consumptive (nonproductive) return has important and, in some cases, dramatic implications for optimal taxes and tuition fees. Using a simple model, we show that when the consumption share in education is endogenous and tuition fees are unconstrained, the optimal tax/fee system involves regressive income taxes and high tuition fees. A progressive labor income tax system may, on the other hand, be a second‐best response to politically constrained, low tuition fees. Finally, the existence of individuals with different abilities will also move the optimal income tax system toward progressivity.     

Taxation Reform: Some Economic Issues

The Australian system of Commonwealth and State taxes is in need of comprehensive reform. It fails the criteria of neutrality, horizontal equity and simplicity, it is not as progressive as often thought, and the future revenue base is declining. Many of the problems stem from the absence of comprehensive tax bases as applied to income, expenditure and assets, and related choice options are subjected to very different effective tax burdens. Important choice options facing different effective tax rates include: work and leisure; consumption and saving; different saving and investment options; form of labour remuneration; different ways of production; the mix of goods and services produced and consumed; and, domestic or overseas location.
A comprehensive income tax base is required, especially as applied to the taxation of capital income. The options of a nominal income, real income or expenditure base are explored.
It is argued that reform of indirect taxes proceed along two lines. The general revenue raising purpose leads to a comprehensive base of final consumption expenditure at a single rate. Then, additional specific taxes for user pays purposes, for example for roads, and for externalities, for example tobacco, set at the supply cost or net externality would be applied.
There are conflicting arguments for and against changing the tax mix away from income to expenditure.     

Taxation for the 21st century: the automated payment transaction (APT) tax

This paper examines the desirability and feasibility of replacing the present system of personal and corporate income, sales, excise, capital gains, import and export duties, gift and estate taxes with a single comprehensive revenue neutral Automated Payment Transaction (APT) tax. In its simplest form, the APT tax consists of a flat tax levied on all transactions. The tax is automatically assessed and collected when transactions are settled through the electronic technology of the banking/payments system. The APT tax introduces progressivity through the tax base since the volume of final payments includes exchanges of titles to property and is therefore more highly skewed than the conventional income or consumption tax base. The wealthy carry out a disproportionate share of total transactions and therefore bear a disproportionate burden of the tax despite its flat rate structure. The automated recording of all APT tax payments by firms and individuals eliminates the need to file tax and information returns and creates a degree of transparency and perceived fairness that induces greater tax compliance. Also, the tax has lower administrative and compliance cost. Like all taxes, the APT tax creates new distortions whose costs must be weighted against the benefits obtained by replacing the current tax system.     

Shifting Taxes from Labor to Consumption: More Employment and more Inequality?

This paper investigates the effect of shifting taxes from labor income to consumption on labor supply and the distribution of income in Germany. We simulate stepwise increases in the value‐added tax (VAT) rate, which are compensated by revenue‐neutral reductions in income‐related taxes. We differentiate between the personal income tax (PIT) and social security contributions (SSC). Based on a dual data base and a microsimulation model of household labor supply behavior, we find a regressive impact of such a tax shift in the short run. When accounting for labor supply adjustments, the adverse distributional impact persists for PIT reductions, while the overall effects on inequality and progressivity become lower when payroll taxes are reduced. This is partly due to increases in aggregate labor supply, resulting from higher work incentives.     

Are Consumption Taxes Regressive?

It is often argued that a general consumption tax is necessarily regressive, particularly because households with high incomes typically save relatively more than those with low incomes. This paper uses very simple tax models to examine the combination of income and consumption taxes. It suggests that it is preferable to consider the overall impact of all taxes and transfers rather than relating payments of a single tax to gross income, instead of the relevant tax base. Insofar as savings might be relevant, attention should be given to the income tax treatment of investment income.     

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.     

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.     

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.     

Effect of the Tax System ON R&D Intensity,Growth, Wages and Consumption Share

We propose a general equilibrium knowledge‐driven (semi‐)endogenous‐growth model with horizontal R&D, which is extended to consider two types of labour, skilled and unskilled, and exogenous government expenditure, financed through taxes on financial assets and on labour income, to analyse the implications of the tax system on R&D intensity, economic growth, wage inequality and consumption share in the output. In particular, we show that: (i) taxes have negative influence in the consumption share, being higher the marginal effect of the labour‐income tax; (ii) for any given government expenditure share, an increase (a decrease) in financial‐assets tax decreases (increases) the labour‐income tax; (iii) only the financial‐assets tax affects negatively the R&D intensity and the skill‐premium; thus, to reduce the skill‐premium the financial‐assets tax must increase; (iv) ignoring the effect on wage inequality and on R&D intensity, taxes are substitutes.     

THE BUILT-IN FLEXIBILITY OF INCOME AND CONSUMPTION TAXES IN NEW ZEALAND

This paper provides estimates of individual and aggregate revenue elasticities of income and consumption taxes in New Zealand, based on the 2001 tax structure and expenditure patterns. Using analytical expressions for revenue elasticities at the individual and aggregate levels, together with a simulated income distribution, values for New Zealand were obtained. Results using equi-proportional income changes suggest that the aggregate income and consumption tax revenue elasticities are both fairly constant as mean income increases, at around 1.3 and 0.95 respectively. This latter estimate assumes that increases in disposable income are accompanied by approximately proportional increases in total expenditure. If there is a tendency for the savings proportion to increase as disposable income increases, a somewhat lower total consumption tax revenue elasticity, of around 0.9, is obtained for 2001 income levels. However, non-equiproportional income changes are more realistic. Allowing for regression towards the geometric mean income reduces these elasticities, giving an elasticity for income and consumption taxes combined that is only slightly above unity. Examination of the tax-share weighted expenditure elasticities for various goods also revealed that, despite the adoption of a broad based GST at a uniform rate in New Zealand, the persistence of various excises has an important effect on the overall consumption tax revenue elasticity, especially for individuals at relatively low income levels.     

THE OPTIMAL DIVISION OF GOVERNMENT EXPENDITURE BETWEEN PUBLIC GOODS AND TRANSFER PAYMENTS

This paper examines the optimal ratio of transfer payments to expenditure on public goods, for a given income tax rate. The transfer payment is then determined by the government's budget constraint. The optimal ratio of transfers to public good expenditure per person is expressed as a function of the ratio of the median to the arithmetic mean wage, and of the tax rate. Reductions in the skewness of the wage rate distribution are associated with reductions in transfer payments relative to public goods expenditure, at a decreasing rate. Furthermore, increases in the tax rate, from relatively low levels, are associated with increases in the relative importance of transfer payments. But beyond a certain level, further tax rate increases are associated with a lower ratio of transfers to public goods, because of adverse incentive effects.     

Changing the Tax Mix

A tax mix change, including a component of the Australian tax reforms, involves a net increase in taxation of consumption and a net decrease in income taxation. If the tax mix change is approximately aggregate revenue neutral and retains current vertical equity, the new income tax rate schedule must be more progressive than the current schedule. The Australian proposal involves a revenue shortfall and some erosion of vertical progressivity. For the large proportion of households who save very little, the tax mix change has negligible effects on incentives and efficiency, and on total tax paid.     

Relative Consumption Concerns and the Optimal Tax Mix

This paper studies the optimal tax mix (taxes on income and commodities) under asymmetric information in a two‐type model, when individuals make relative consumption comparisons. The model includes both positional and nonpositional goods, taking into account the fact that relative concerns matter for some but not for all commodities. We find that in general the whole tax system is affected by the externalities caused by the consumption of positional goods, notably also the taxes on income and on a nonpositional good. The tax rates on positional goods are higher than in the absence of status effects, reflecting their Pigouvian role. The sign of the Pigouvian part in the income tax schedule is ambiguous and depends crucially on whether status goods are complements or substitutes to leisure.     

How progressive are indirect taxes in Russia?

The interplay of a differentiated indirect tax structure and the variation in expenditure patterns across households leads to a possibly unequal distribution of indirect tax liabilities across the population. This paper uses the ninth round of the RLMS survey to assess the distributional consequences of the two major components of the Russian indirect tax system: VAT and excise taxes. According to the Kakwani index, the global indirect system can be considered to be progressive overall. Decomposition into constituent terms shows that this is due not only to a progressive VAT structure, but also to progressive excise taxes. This result is partly explained by the progressivity of the excise tax on car fuel, but is also sensitive to peculiarities in the data about alcohol consumption.     

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.     

Progressive taxes and automatic stabilization in an open economy

In a simple model with a fixed exchange rate, more progressive taxes are likely to lead to a fall in the multiplier for autonomous expenditure. The effect on the multiplier for an autonomous wage shock may go either way, and increased progressivity may change the sign of this multiplier. The wage bargaining is modeled as a trade-off between employment and real disposable income. Depending on them weight attached to employment and the way expectations are formed, more progressivity may contribute to stabilize rather than destabilize this wage formation process. Indexation of taxes to imported inflation seems preferable to alternatives.

Fiscal Policy and Long-run Growth in R&D-based Models with Endogenous Market Structure

This paper shows that in a model of endogenous growth that does not exhibit the scale effect, taxes on consumption and labor income and the level and composition of public expenditure have no effect on steady-state growth. The only fiscal instruments that affect steady-state growth are taxes on asset and corporate income. In line with standard intuition, tax rates and public expenditure have level effects on income per capita. These results emphasize that although growth is endogenous, in the sense that it is determined by the model and it is subject to policy action, instruments that work by changing market size do not affect it. Effective growth-enhancing policies operate through the interest rate.     

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.     

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。
