This paper presents for the .rst time the properties of optimal piece-wise linear tax systems for two-earner households, based on joint and individual incomes respectively. A key contribution is the analysis of the interaction of second earner wage di¤erences, variation in prices of bought-in...

The Mirrlees Review of the UK tax system, together with its companion volume of research papers, can be expected to influence future discussions of tax reform. Indeed, this can already be recognised in the Henry Review. As far as income taxation is concerned, the most substantive recommendation...

We analyze optimal taxation in an economy with monopsonistic labour markets. The individuals, whose only decisions are whether to work, or not, have heterogeneous productivities and opportunity costs of work. Given its preferences for redistribution, the government, which does not observe the...

In this paper, we test one of the fundamental assumptions in the tax competition literature, namely, that a country's taxable income depends on the tax policies pursued in the domestic and in neighbouring countries. Based on a panel of annual data of 14 Western European countries spanning the...

Recent literature on optimal nonlinear taxation has shown that in models with a single level of government public provision of private goods can help redistribution by mitigating self-selection constraints. The aim of the present paper is to extend the analysis to a fiscal federalism setting...

The focus of the present paper is on the intragenerational effects of nonlinear income taxation in a multiperiod framework. We investigate whether it is possible to achieve redistribution at smaller efficiency costs by enlarging the message space adopted in standard tax system (which only...

This paper addresses optimal taxation, when the relationship between consumption and environmental damage is uncertain and treated as a random variable by policy makers. The main purpose is to analyze how additional uncertainty about this relationship affects the optimal unit tax on the...

In contrast to the classic result in Diamond and Mirrlees (1971) that fiscal taxes should not be levied on intermediate use of goods, Newbury (1985) showed that, in a closed economy with Leontief technology, input taxes should be used to indirectly tax commodities that for some reason are...

This paper is concerned with the question of how couples should be taxed. One reason for the importance of this issue is simply that the overwhelming majority of individuals live in households formed around couples, and so it could be argued that empirically, this is the single most important...

We study taxation externalities in federations of benevolent governments. Where different hierarchical government levels tax the same base, one can observe two types of externalities: a horizontal externality, working among governments of the same level and leading to tax rates that are too low...
