A common claim in the policy discourse is that a government wishing to achieve equality of opportunity should use public provision of education for equalisation of opportunities rather than income taxation, which only equalizes incomes. We develop a framework in which the tax and education...

Previous literature has shown that public provision of private goods can be a welfare-enhancing device in second-best settings where governments pursue redistributive goals.However, three issues have so far been neglected. First, the case for supplementing an optimal nonlinear income tax with...

We analyze the impact of (exogenous) tax morale on the optimal design of progressive income taxation. In our model, only universal basic income (transfer) is financed from a linear income tax and the financing of public goods is neglected. Each individual supplies labor and (un)declares earning,...

Belgium has seen major changes in its tax-benefit system over the past twenty years. These changes have, to a large extent, co-determined the evolution of disposable incomes of Belgian households on one hand, and their incentives to work on the other. In this paper we assess equity and...

Analyzing a homogenous household setting with endogenous fertility and endogenous labor supply, we demonstrate that moving from joint taxation to individual taxation and adapting child benefits so as to keep fertility constant entails a Pareto improvement. The change is associated with an...

We derive a general optimal income tax formula when individuals respond along both the intensive and extensive margins and when income effects can prevail. Individuals are heterogeneous across two dimensions: their skill and their disutility of participation. Preferences over consumption and...

This paper characterizes optimal income taxation when individuals respond along both the intensive and extensive margins. Individuals are heterogeneous across two dimensions: specifically, their skill and disutility of participation. Preferences over consumption and work effort can differ with...

Relative consumption effects or status concerns that feature jealousy (in the sense of Dupor and Liu, AER 2003) boost consumption expenditure. If consumption is financed by labour income, such status considerations increase labour supply and, hence, the tax base. A higher taxable income, in...
