Income tax policy and lifetime labor supply

A progressive income tax structure provides incentives for individuals to alter their rate of work and their age of retirement. Compared to a zero tax or proportional tax equilibrium, progressive taxation induces individuals to take less leisure in the form of retirement in exchange for more leisure during the worklife, especially at high wage levels. The imposition of a special pension tax provision on top of a progressive tax structure offsets the distortion on leisure alternatives imposed by progressivity. Indeed, the pension tax deferral provision can neutralize the impact of tax progressivity on the work profile over life. The magnitude of these tax inducements in the U.S. tax structure are non-trivial and therefore are expected to alter labor supply decisions over the lifetime. The model finds empirical support using data from the Social Security Newly Entitled Beneficiaries Survey.     

Taxation and Tournaments

This paper analyzes the effects of progressive taxes on labor supply and income distribution in the context of the rank‐order tournament model originally developed by Lazear and Rosen (1981). We show conditions under which a more progressive tax schedule will cause so large general equilibrium effects that the inequality in disposable income will actually increase. We also show that a non‐zero redistributive tax is always optimal if society's welfare function displays inequality aversion; this result always holds, regardless of behavioral responses and general equilibrium effects.     

How and why transition made income inequality increase in urban Russia: A local study

Using sample surveys from the city of Taganrog in 1989 and 2000, we investigate household income, its composition, and its distribution in urban Russia. Income inequality increased greatly as real income at the lowest part of the distribution decreased considerably. Earnings are more concentrated in the upper part of the income distribution in 2000 than in 1989. For many households, public transfers, allowances, private transfers, or subsidiary earned income prevented income from falling further. However, Russia did not inherit from its Soviet past an efficient progressive tax system or programs to protect jobless workers and households facing severe drops in income.

Child allowances,educational subsidies and occupational choice

This paper examines the effects on occupational choice and capital accumulation attributable to government policies of child allowances and educational subsidies. We show that multiple steady states may arise under these two policies, with club convergence occurring, and the initial condition being of relevance, if the tax rate of labor income for skilled labor is fairly high. Under a policy of child allowances, an increase in the tax rate is found to raise the quantity of children, but lower the quality of adults; however, under a policy of educational subsidies, with an increase in the tax rate, corresponding increases are found in both the quantity of children and the quality of adults. For developed countries, introducing child allowances may improve or hurt the welfare while introducing educational subsidies is welfare improving.     

企业行为约束下技术创新所得税激励政策效应研究

技术创新所得税激励政策效应的发挥不但取决于政策本身的制度设计,还取决于企业投资行为对税收政策的敏感性。技术创新所得税激励政策作为制度驱动,既受到企业自身行为的约束,又与企业内部研发驱动机制相互作用。在企业行为理论框架下,运用随机效应模型,以2009—2013年中国Ａ股上市公司数据为样本,对企业行为约束下中国技术创新所得税激励政策效应进行了理论分析和实证检验。结果发现,税收优惠政策形成的税收补贴通过转化为企业内部资源、降低研发投资风险,使得企业内部驱动机制对研发支出的积极作用增强;所得税激励政策本身并未对企业技术创新活动产生显著的激励作用。     

Laffer strikes again: Dynamic scoring of capital taxes

We set up a neoclassical growth model extended by a corporate sector, an investment and finance decision of firms, and a set of taxes on capital income. We provide analytical dynamic scoring of taxes on corporate income, dividends, capital gains, other private capital income, and depreciation allowances and identify the intricate ways through which capital taxation affects tax revenue in general equilibrium. We then calibrate the model for the US and explore quantitatively the revenue effects from capital taxation. We take adjustment dynamics after a tax change explicitly into account and compare with steady-state effects. We find, among other results, a self-financing degree of corporate tax cuts of about 70–90% and a very flat Laffer curve for all capital taxes as well as for tax depreciation allowances. Results are strongest for the tax on capital gains. The model predicts for the US that total tax revenue increases by about 0.3–1.2% after abolishment of the tax.     

Corporation tax revenue growth in the UK: A microsimulation analysis

This paper examines the built-in flexibility properties — as measured by the elasticity of revenue with respect to profits — of the UK corporation tax system. Emphasis is placed on determining some of the major influences on the extent to which total corporation tax revenue changes when profits change over the economic cycle. A microsimulation model, CorpSim, is constructed and used to obtain numerical results. In the model, corporations use group relief, capital allowances and losses in a tax-minimising manner. The growth of aggregate corporation tax revenue in practice in the UK appears to be highly volatile in relation to the growth of profits. High volatility in revenue elasticities is found to be especially associated with economic downturns. In mild economic downturns, corporation tax revenue elasticities may rise (because tax growth falls less than profit growth), but in more severe downturns, large but temporary decreases in revenue elasticities (and even negative elasticities) can be expected.     

Earned Income Tax Credits: Do They Have Any Role to Play in Australia?

Earned income tax credits (EITCs) have been used mainly in the United States. The Australian tax–transfer system is already very complicated and the aims of the EITC—notably reductions in effective tax rates for low income earners—might be achievable through reforms to existing components of the system. Such tax rates can be lowered either through reductions in social security tapers, or reductions in income tax payable. Action to reduce tapers affecting families is already proceeding through the social security component of the Government's tax reform package. To go further, by reducing tapers on the main allowances, like Newstart Allowance and Parenting Payment, would accelerate developments for such allowances to become forms of wage supplementation for the low paid. If it were not desired to go further down this path (and it does have problems), then relief of income tax burdens could be implemented through changes to the rate structure. While the EITC may make sense in the US context, a country with a well-developed welfare system like that of Australia has other options. In particular any EITC in this country is likely to be a supplement, not an alternative, to existing cash support for low income families.     

On the Optimal Taxation in a Growth Model of the Mixed Economy

Previous studies of second‐best taxation have shown that capital income shall not be taxed in the long run for some cases where individuals have infinite lives and a utility function of special form. The present paper improves upon this conclusion in two respects: first, the utility function may be of more general form, and second, zero capital income tax is required for the entire period, which does not depend on whether the individual's horizon is infinite or finite. Furthermore, we also show that the optimal tax rate on capital income should tend to zero in the long run if the first‐best optimum is attainable.     

Supply-Side Economics of Germany's Year 2000 Tax Reform: A Quantitative Assessment

Abstract. The paper provides an assessment of supply‐side economics following Germany's year 2000 tax reform. Investigated are a corporate tax cut, deteriorating depreciation allowances and imputation rules, and a private income tax cut. For this purpose, a neoclassical growth model is augmented by various fiscal policy parameters and endogenous corporate finance and calibrated with German data. The model is used to evaluate consequences of Germany's tax reform on production, firm finance and leverage, investment, consumption and welfare of a representative household.     

Progressive Taxation, Moral Hazard, and Entrepreneurship

This paper considers the general equilibrium and welfare effects of a linear progressive income tax with entrepreneurship and moral hazard. A competitive intermediation sector diversifies risk associated with entrepreneurial activity, but full risk consolidation is prevented by moral hazard. Since effort is not observable, risk bearing of entrepreneurs is required for incentive reasons. The extent of risk consolidation is endogenously explained. We find that a nonredistributive tax is neutral. A progressive tax always impairs entrepreneurship while the effect on welfare can be positive or zero, depending on the specification of moral hazard. Some results may also depend on the concrete formulation of preferences.     

The geometry of optimal taxation: a primal approach

We characterize zero tax results geometrically as a condition on indifference curves and the implementability constraint. The condition can also be expressed as a generalized homotheticity condition on the utility function and also extends older results on uniform taxation that use the duality approach. Many zero taxation results in dynamic macroeconomics can be derived from our characterization; thus it provides a unified framework for a systematic study of these phenomena. Our geometric method also allows to study the sign of deviations from zero tax results in more complicated frameworks such as taxation without commitment.      

Corporate Tax Incentives for R&D Investment in OECD Countries

Differentiating internal equity from debt finance, this study examines the generosity of R&D-specific tax incentives in OECD countries based on an NPV model. The corporate tax system generally favours debt finance and some previous findings on the possible preponderance of internal equity for financing R&D investment cannot be explained in relation to R&D-specific tax concessions. The OECD comparison demonstrates that R&D tax allowances adopted in the Czech Republic, Belgium, the UK, Denmark, Hungary, Austria and Australia generated the most substantial tax savings in 2006. Combined with such incentives, the after-tax NPV increases with the corporate tax rate, suggesting stronger investment stimulation through a tax-rate-increase-cum-base-broadening policy.     

Tax progressivity, income distribution and tax non-compliance

This article examines the determinants of tax non-compliance when we recognise the existence of an imperfectly competitive “tax advice” industry supplying schemes which help taxpayers reduce their tax liability. We apply a traditional industrial organisation framework to model the behaviour of this industry. This tells us that an important factor determining the equilibrium price and hence, the level of non-compliance, is the convexity of the demand schedule. We show that in this context, this convexity is affected by the distribution of pre-tax income, the progressivity of the tax-schedule and the way in which monitoring and penalties vary with income. It is shown that lower pre-tax income inequality as well as a less progressive tax code may cause more tax minimisation activities. Therefore, the frequently advocated policy of reducing the highest tax rate may fail as a policy directed at improving tax discipline. One way of offsetting the possible harm to tax compliance from a less progressive tax could be an adjustment of the penalty and monitoring functions.     

Environmental Quality,Income Distribution,and Factor Mobility: The Consequences of Local Action

This paper discusses the regressive nature of tax exemptions for children compared to child allowances and estimates the decline in child poverty in several developed countries due to child allowances. The paper then estimates the decline in child poverty in the United States due to tax exemptions for children and simulates the impact of various possible child allowance programs on child poverty in the United States. It finds that a $3000 to $4000 child allowance would reduce child poverty in the United States to the level of other developed nations and, due to the costs associated with child poverty, be a cost effective policy change.

Taxation,corporate financial policy,and the cost of capital: A comment

Theoretical models of the incidence of the corporate profits tax differ as to whether the tax distorts the allocation of resources, or is a lump-sum tax on the owners of capital. These differences derive from the assumptions made about the special provisions of the tax system with regard to the deduction of interest payments and investment expenditure. Two non-distortionary systems are identified which are shown to be equivalent to a capital levy when the tax is introduced and a zero tax on profits. Under the present UK system, however, a higher rate of corporation tax stimulates investment.     

What Should Optimal Income Taxes Smooth?

According to the theory of tax smoothing, income tax rates should be kept constant so as to minimize the distortionary costs of taxation. By explicitly considering how labor supply is distorted by income taxes in a fully specified intertemporal model, we find that the optimal income tax policy should smoothen leisure. In the case of varying income (productivity changes) this is attained by a pro‐cyclical (progressive) tax rate.     

Capital Mobility, Agglomeration and Corporate Tax Rates: Is the Race to the Bottom for Real?

Based on a data set for 19 OECD countries for the period 1981–2001,we estimate the impact of FDI on corporate tax rates, wherechanges in FDI are a measure for changes in capital mobility.So far the literature has been concerned with the related butrather different question as to the sensitivity of FDI to taxrates. Our article takes an opposite perspective and asks whatthe impact of capital mobility is on corporate tax rates. Indoing so, we explicitly take the role of agglomeration intoaccount. In theory, core countries can afford a higher tax ratecompared to peripheral countries. In our estimation strategy,we instrument capital mobility to deal with reverse causality.The main conclusion is that increased international capitalmobility, measured by FDI flows, implies a lower corporate taxrate. But we also find that agglomeration matters: core countrieshave a higher corporate tax rate than peripheral countries.If there is a race to the bottom, it seems that it is more realfor some countries than others.

Endogenizing technological progress: The MESEMET Model

This paper endogenizes technology and human capital formation in the MESEM model that was developed by van Sinderen (Economic Modelling, 1993, 13, 285–300). Tax allowances for private R & D expenditures and public expenditures on both education and R & D are effective instruments to stimulate economic growth. Simulations with respect to market clearing, the importance of supply-side elements and key parameters (such as the magnitude of spillovers and substitution elasticities) reveal that tax allowances for private R & D are the most robust instrument to increase economic growth through the accumulation of knowledge. Contrary to other studies that find that technology policies typically reduce employment, we find that overall employment rises.
