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...

We impose a horizontal equity restriction on the problem of finding the optimal utilitarian tax mix. The horizontal equity constraint requires that individuals with the same ability have to pay the same amount of taxes regardless of their preferences for leisure. Contrary to normal findings, we...

In this paper we examine the desirability of subsidizing child care expenditures in a model where parents can choose both the quantity and the quality of child care services they purchase in the market. Our vehicle of analysis is a Mirrleesian optimal tax framework where child care services not...

This paper highlights the possibility that negative marginal tax rates arise in an intensive-margin optimal income tax model where wages are exogenous and preferences are homogeneous, but where agents differ both in skills (labor market productivity) and their needs for a work-related...

A standard result in the optimal taxation literature is that, when agents differ in market ability and the government aims at redistributing from high- to low-skilled agents by means of an optimal nonlinear labor income tax and a set of commodity taxes, an optimally designed commodity tax...

Using an OLG model with skill uncertainty and private savings, we investigate whether an optimally designed set of public pension transfers can usefully supplement a nonlinear labor income tax as a welfare-enhancing policy instrument. We consider a Mirrleesian setting where agents' skills are...

This paper deals with the consequences of the assumption of negatively interdependent preferences for the shape of the optimal nonlinera income tax and the efficient level of public good provision in a setting where the policy maker maximizes an inequality averse social welfare function and the...

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...

We study the joint design of nonlinear income and education taxes when the government pursues redistributive objectives. A key feature of our setup is that the ability type of an agent can affect both the costs and benefits of acquiring education. Market remuneration of agents depends on both...
