In a number of high-income countries over the past few decades there has been a large growth in income inequality and at the same time a shift in the burden of taxation from the top to the middle of the income distribution. This paper applies the theory of optimal piecewise linear taxation to...

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...

This paper presents for the first time the properties of optimal piecewise 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 differences, variation in prices of bought-in...

This paper develops a simulation model in order to examine the effectiveness of state attempts at redistribution under a variety of migration elasticity assumptions. Key outputs from the simulation include the impact of tax-induced migration on state revenues, excess burden, and fiscal...

Motivated by the observation that access to evasion opportunities is distributed heterogeneously across the labor market, this paper examines the extent to which labor supply elasticities with respect to tax rates depend on such evasion opportunities. We first discuss the channels through which...

This paper examines whether risk-taking in a lottery depends on the opportunity to respond to the lottery outcome through additional labor effort and/or tax evasion. Previous empirical attempts to answer this question face identification issues due to self-selection into jobs that facilitate tax...

This paper applies the theory of relational contracts to make precise the idea that because households are engaged in a repeated non-cooperative game, Pareto efficient outcomes can be supported by self interest, given the specific pattern of specialisation and exchange which exists in the...

This paper characterizes optimal non-linear income taxation in an economy with a continuum of unobservable productivity levels and endogenous involuntary unemployment due to frictions in the labor markets. Redistributive taxation distorts labor demand and wages. Compared to their efficient...

Does joint taxation disadvantage women? To answer that question, this paper begins by reviewing unitary and bargaining models of intrafamily allocation, and then discusses the determinants of "bargaining power" in a world without taxes. It argues that wage rates rather than earnings are...

The purpose of this paper is to introduce and adopt a generalised version of Roemer's (1998) Equality of Opportunity (EOp) framework, which we call extended EOp, for analysing second-best optimal income taxation. Unlike the pure EOp criterion of Roemer (1998) the extended EOp criterion allows...
