In most countries, average income varies with age. In this paper we investigate if and how it is possible to enhance the redistributive mechanism by relating tax payments to age. Using an OLG model where some individuals are low skilled all their life while others are low skilled when young but high skilled when old, we first show how an age "dependent" optimal income tax can Pareto improve upon an age "independent" income tax. We then characterize the optimal age "dependent" income tax. A tax on interest income is part of the optimal tax structure. Copyright � The editors of the "Scandinavian Journal of Economics" 2008 .

The incidence and efficiency losses of taxes have usually been analysed in isolation from public expenditures. This negligence of the expenditure side may imply a serious misperception of the effects of marginal tax rates. The reason is that part of the marginal tax may in fact be payment for publicly provided goods and reflects a cost that the consumers should bear in order to face the proper incentives. Hence, part of the marginal tax serves the same role as a market price in the sense that it conveys information about a real social cost of working more hours. We develop this idea formally by studying an optimal income tax model in combination with a type of public provision scheme not analyzed before; the provision level is individualized and positively associated with the individual's labor supply. As examples we discuss child care, elderly care, primary education and health care. We show that there is a gain in efficiency where public provision of such a service replaces market purchases. We also show that it is necessary for efficiency that marginal income tax rates are higher than in economies where the services are purchased in the market. This is because the optimal tax should be designed so as to face the taxpayers with the real cost of providing the services. Hence, it might very well be that economies with higher marginal tax rates have less severe distortions than economies with lower marginal tax rates.

The Welfare Gains of Age Related Optimal Income Taxation Abstract Using a calibrated overlapping generations model we quantify the welfare gains of an age dependent income tax. Agents face uncertainty regarding future abilities and can by saving transfer consumption across periods. The welfare gain of switching from an age-independent to an age-dependent nonlinear tax amounts in our benchmark model to around three percent of GDP. The gains are particularly high when there are restrictions on debt policy. The gains of using a nonlinear-as opposed to a linear tax are even larger. Surprisingly, it is of secondary importance to optimally choose the tax on interest income. Terms of use: Documents in EconStor mayJEL-Code: H21, H23, H24.
