This paper studies the tax treatment of couples. We develop two different approaches. One is tailored to the analysis of tax systems that stick to the principle that the tax base for couples is the sum of their incomes. One is tailored to the analysis of reforms toward individual taxation. We...

This paper studies optimal non-linear income taxation in a model with labor supply responses at the intensive (hours, effort) and extensive (participation) margins. It shows that an Earned Income Tax Credit (EITC) with negative marginal taxes and negative participation taxes at the bottom is...

This paper analyses the optimal tax policy and public provision of private goods when individuals differ in two respects: income-earning ability and rationality. Publicly provided goods should be overprovided or subsidised, relative to the decentralised optimum, if society's marginal valuation...

We present a non-cooperative model of a family's time allocation between work and a home-produced public good, and examine whether the income tax should apply to couples or individuals. While tax-induced labor supply distortions lead to overprovision of the public good, spouses' failure to...

This paper reviews the literature on optimal taxation of labour income and the empirical work on labour supply and the elasticity of taxable income in Sweden. It also presents an overview of Swedish taxation of labour income, offers calculations on the development in effective marginal tax rates...

Addressing extensive labour supply responses, the literature has established a case for larger transfers to the working poor than to even poorer non-working people. This paper casts new light on this result. I argue that the result hinges crucially on the labour supply responses of people in...

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...
