Tuition fees: User prices and private incentives

This paper studies the aggregate and distributional implications of introducing tuition fees for public education services into a tax system with income and consumption taxes. The setup is a neoclassical growth model where agents differ in capital holdings. We show that the introduction of tuition fees (a) improves individual incentives to work and/or save and (b) can be both efficient and equitable. The focus is on the role of tuition fees as an extra price and how this affects private incentives.     

Public and Private Education in an Integrated Europe: Studying to Migrate and Teaching to Stay?

This paper investigates public and private choices between internationally applicable and country‐specific education when graduates are mobile. Human capital depends on innate skills and study effort with either type of education. It is shown that national governments provide too few students with internationally applicable education, and too many with country‐specific education. This effect is mitigated, but not entirely eliminated, by the introduction of a graduate tax, according to which graduates are required to pay part of their taxes to the country where they received their education, regardless of residence. However, private educational choices are socially optimal with suitably differentiated tuition fees.     

Rethinking Hecs: Its Definition and Fiscal Role in Compensating for Non-deductibility of Tuition Fees

This paper develops a two period model of the higher education decision to determine the required return from higher education. It uses the model to calculate the proportion of full tuition costs which should be charged 'up front' under the Australian Higher Education Scheme (HECS), in order to compensate for the fact that such fees are not deductible against income for tax purposes. Because full tuition costs represent less than 11 per cent of the total costs of higher education, the ideal HECS ratio is relatively high, in the region of 0.7. The low relative importance of tuition costs means that fee subsidy schemes cannot possibly compensate for other distortions such as income tax progression which persist over the working life of graduates.     

The Design of Optimal Education Policies

This paper studies the education policy chosen by a utilitarian government. In the model, households differ in their income and in their children&'s ability; income is observed by the government, but ability is private information. Households can use private education, but cannot borrow to finance it. The government can finance education with income tax, but at the cost of blunting the individuals' incentive to exert labour market effort. The optimal education policy we derive is elitist: it increases the spread between the educational achievement of the bright and the less bright individuals, compared to private provision. It is also such that the education received by less bright individuals depends positively on their parental income. Finally, the optimal education policy is input regressive, in the sense of Arrow (1971, Quarterly Journal of Economics, 38, 175–208): households with higher income and brighter children contribute less in tuition fees towards the cost of the education system than households with lower income and less bright children.     

“费改税”的目标及思路

“费改税”是针对目前中国“费大于税”的不规范的政府收入格局而提出的一项改革任务和政策主张。如果对“费改税”这种改革作更全面、更准确的称呼,实际上指的是以清理整顿预算外、制度外资金和各种收费为前提,使政府税收、使用费和非政府预算的商业性收费分流归位的一种综合性税费改革,从而形成不同性质、不同形式资金的较规范的分流归位。     

中国矿业税费法律制度的重构——以矿产所有权出让为视角

从实证分析的角度而言,在采矿权出让中,国家出让的是矿产的所有权而非用益物权。采矿权价款作为矿产的用益物权的对价,占矿产品的实际销售收入的比例太低。按矿产品的实际销售收入征收矿产资源补偿费和税收,国有矿产资源资产和税收大量流失。我国应实行矿产所有权出让,向受让人收取矿产所有权出让金、矿区国有土地使用费、矿山环境恢复费。根据矿产所有权出让金的数学模型,确定它的合理金额。按照同矿产的可采储量等量的矿产品的销售收入,征收环境税、增殖税,取消矿产资源补偿费和资源税。     

关于完善我国环保型税收政策的探讨

环保型税收在环境保护方面具有不可替代的作用。随着我国经济发展环境问题日益凸现,运用税收手段解决环境问题已成为各国通行的做法。鉴于我国目前以流转税为主,经济发展水平不高,所以不能完全照搬西方的做法,但西方发达国家生态税有许多值得我们借鉴的成功经验。我国税制中与生态环境有关的政策,散见于资源税、消费税、企业所得税等几个税种中,有些仍以费的形式存在,有较大的空间。建议应增加现行税种的环境保护内涵,实行专门的环保税种,实行费改税等。     

Trade,environment, and income inequality: An optimal taxation approach

In a small open economy, how should a government pursuing both environmental and redistributive objectives design domestic taxes when redistribution is costly? And how does trade liberalization affect the economy's levels of pollution and inequalities, when taxes are optimally and endogenously adjusted? Using a general equilibrium model under asymmetric information with two goods, two factors (skilled and unskilled labor), and pollution, this paper characterizes the optimal mixed tax system (nonlinear income tax and linear commodity and production taxes/subsidies) with both production and consumption externalities. While optimal income taxes are not directly affected by environmental externalities, conditions are derived under which under‐ or over‐internalization of social marginal damage is optimal for redistributive considerations. Assuming that redistribution operates in favor of the unskilled workers and that the dirty sector is intensive in unskilled labor, simulations suggest that trade liberalization involves a clear trade‐off between the reduction of inequalities and the control of pollution when the source of externality is only production; this is not necessarily true with a consumption externality. Finally, an increase in the willingness to redistribute income toward the unskilled results paradoxically in less pollution and more income inequalities.     

Optimal tax rules and public sector efficiency with an externality in an overlapping generations model

This paper examines optimal tax rules and public sector efficiency, integrating them in a second-best world with pollution by using an overlapping generations model. The second-best world is characterized by the comparative statics of green preferences. The main results obtained are as follows. First, the marginal cost of public funds may be reduced by the externalities, regardless of the choice of taxes. Second, optimal environmental and non-environmental tax rules are additively and directly affected by the dynamic efficiency of capital accumulation per unit labour (DECAL), and indirectly by it, through the efficiency of the public sector. Environmental taxes going beyond Pigovian ones may be welfare-improving if the DECAL is improved by the environmental tax. Even optimal non-environmental tax rules should additively and directly counter the dynamics of pollution to consider the income effects of the optimal tax system for the future. Third, the “additivity property,” or the “principle of targeting,” does not hold even in the absence of incentive compatibility constraints. The essential reasons for this are clarified as follows: distortions that should be countered by taxes; that is, the income effects of the optimal tax system and the DECAL in this model, break the equality between optimal environmental taxes and the externalities measured by governments. Finally, growing environmental concerns may, in fact, increase pollution. The inverse relationship between environmental and labour income taxes may not hold.     

The determination of public tuition fees in a mixed education system: A majority voting model

We study the determination of public tuition fees through majority voting in a vertical differentiation model where agents' returns on educational investment differ and public and private universities coexist and compete in tuition fees. The private university offers higher educational quality than its competitor, incurring higher unit cost per trained student. The tuition fee for the state university is fixed by majority voting while that for the private follows from profit maximization. Then agents choose to train at the public university or the private one or to remain uneducated. The tax per head adjusts in order to balance the state budget. Because there is a private alternative, preferences for education are not single‐peaked and no single‐crossing condition holds. An equilibrium is shown to exist, which is one of three types: high tuition fee (the “ends” are a majority), low tuition fee (the “middle” is a majority), or mixed (votes tie). The cost structure determines which equilibrium obtains. The equilibrium tuition is either greater (majority at the ends) or smaller (majority at the middle) than the optimal one.     

Unions, progressive taxes, and education subsidies

Progressive income taxes moderate distortionary wage demands by trade unions and thereby reduce unemployment, and at the same time underlie disincentives to acquire skills and decrease labour productivity. Governments can respond by combining progressive taxes with subsidies to investment in human capital. A system of generous education subsidies and steep progressive tax rates is more likely to emerge, the greater the market power of trade unions and the better the ability of governments to influence private education decisions. Empirical analysis for several OECD countries provides results consistent with these propositions. A policy mix of high education subsidies and relatively progressive income taxes is found in countries where union membership is significant.     

Social Comparisons and Optimal Taxation in a Small Open Economy

In this paper, we analyze how international capital mobility affects the optimal labor and capital income tax policy in a small open economy when consumers care about relative consumption. The main results crucially depend on whether the government can tax returns on savings abroad. If the government can use flexible residence‐based capital income taxes, then the optimal policy rules from a closed economy largely carry over to the case of a small open economy. If it cannot, then capital income taxes become completely ineffective. The labor income taxes must then indirectly also reflect the corrective purpose that the absent capital income tax would have had.     

Are Higher Education Subsidies Second Best?

An optimal taxation framework is considered in which part of the population can take advantage of investment in higher education. It is shown that social welfare can sometimes be increased by supplementing linear income taxes with a subsidy to material investment in higher education, but that social welfare can never be increased by supplementing a non‐linear income tax with such a subsidy.     

On Optimal Commodity Taxes When Consumption Is Time Consuming

This paper studies the problem of optimal taxation of commodities when consumption is a time‐consuming activity. This is done under two distinct preference separability assumptions: between goods and labor supply, and between goods and leisure. It argues that with the labor separability, the traditional uniform taxation results of optimal tax theory continue to hold. With leisure separability, on the other hand, consumption time is a major ingredient of optimal tax rates. However, the relationship between consumption time and optimal tax rates depends crucially on the representation of the economy. In representative consumer economies, time differences determine the pattern of optimal tax rates so that goods whose consumption take more time are subjected to higher tax rates. When individuals have different earning abilities, redistributive, incentive, and efficiency considerations also come into play resulting in a complex relationship. The paper derives formulas for optimal commodity taxes in this case on the basis of three different tax structures: linear commodity taxes in combination with linear and nonlinear income taxes, and nonlinear commodity taxes in combination with nonlinear income taxes.     

Scholarships or Student Loans? Subsidizing Higher Education in the Presence of Moral Hazard

An income-contingent loan scheme can at best replicate the allocation brought about by a scholarship scheme financed by a graduate tax, and only on condition that there is nothing to stop the policy maker from using tuition fees as if they were taxes. If that is not possible, even the best loan scheme will exclude some well-qualified school leaver from university. Even if individual study effort is observable, but more so if it is not, it is not socially desirable that all students should specialize in the subjects that promise the highest graduate earnings.     

Externalities and optimal taxation

This paper reexamines the optimal tax design problem (income and commodities) in the presence of externalities. The nature of the second–best, and the choice of the tax instruments, are motivated by the informational structure in the economy. The main results are: (i) environmental levies (linear or nonlinear) differ in formula from Pigouvian taxes by the expressions for the optimal tax on private goods; (ii) externalities do not affect commodity tax formulas (linear and nonlinear) for private goods; (iii) externalities do not affect the income tax structure if commodity taxes are nonlinear and affect it if commodity taxes are linear; and (iv) a general income tax plus strictly Pigouvian taxes are sufficient for efficient taxation if individuals of different types have identical marginal rates of substitution (at any given consumption bundle).     

Optimal income taxation with human capital accumulation and limited record keeping

This paper characterizes optimal income taxes in a dynamic economy where human capital is unobservable and the government is restricted to use taxes that depend only on current income. I show that unobservability of human capital tends to decrease the labor wedge, while the effect on the human capital wedge is uncertain. I also analyze the relationship between optimal taxes in economies with and without endogenous human capital and identify two qualitative reasons why the optimal tax codes will differ. I perform numerical simulations to calculate the quantitative relevance of endogenous human capital formation for optimal tax policy. I find that endogenous human capital lowers marginal tax rates by about 9% on average, as compared with a static model without human capital.     

Environmental Taxation,Inequality and Engel’s Law: The Double Dividend of Redistribution

Empirical evidence shows that low-income households spend a high share of their income on pollution-intensive goods. This fuels the concern that an environmental tax reform could be regressive. We employ a framework which accounts for the distributional effect of environmental taxes and the recycling of the revenues on both households and firms to quantify changes in the optimal tax structure and the equity impacts of an environmental tax reform. We characterize when an optimal environmental tax reform does not increase inequality, even if the tax system before the reform is optimal from a non-environmental point of view. If the tax system before the reform is calibrated to stylized data—and is thus non-optimal—we find that there is a large scope for inequality reduction, even if the government is restricted in its recycling options.     

Is commodity taxation unfair?

In a model where agents have unequal skills and heterogeneous preferences about consumption goods and leisure, this paper studies how to combine commodity taxes and non-linear income tax. It proposes a particular social welfare function on the basis of fairness principles. It then derives a simple criterion for evaluating the social welfare consequences of various tax schedules. Under the proposed approach, the optimal tax should have no commodity tax for some range of consumptions, and income redistribution would feature high subsidies to the working poor. It is also shown that, even when the income tax fails to be optimal, commodity taxes may not improve social welfare.     

Optimal income taxation with tax avoidance

We determine the optimal income tax schedule when individuals have the possibility of avoiding paying taxes. Considering a convex concealment cost function, we find that a subset of individuals, located in the interior of the income distribution, should be allowed to avoid taxes, provided that the marginal cost of avoiding the first euro is sufficiently small. This contrasts with the results of Grochulski who shows that, using a subadditive cost function, all individuals should report their true income. We also provide a characterization of the optimal income tax curve.
