This paper characterizes the optimal income and wealth tax schedules when rates of return are endogenous. Individuals exert investment effort in order to increase the return on their investments. Agents are heterogeneous along two dimensions: their investment ability and their labour market...

This paper presents new empirical evidence on taxpayers' responsiveness to taxation by estimating the compensated elasticity of taxable income with respect to the net-of-tax rate in the Netherlands. Applying the bunching approach introduced by Saez (2010), we find small, but clear evidence of...

In this paper we compute the optimal tax and education policy transition in an economy where progressive taxes provide social insurance against idiosyncratic wage risk, but distort the education decision of households. Optimally chosen tertiary education subsidies mitigate these distortions. We...

This paper studies the design of tax systems that implement a planner's second-best allocation in a market economy. An example shows that the widely used Mirrleesian (1976) tax system cannot implement all incentive-compatible allocations. Hammond's (1979) "principle of taxation" proves that any...

Assuming that higher traveling expenses reduce traveling time, this paper considers reliefs for traveling expenses to work when a distorting wage tax is levied. While the decision on traveling expenses would not be distorted if traveling costs were completely deductible, taxation would still not...

This paper proposes the question whether or not traveling expenses to work should be deductible from the income tax base. In order to answer this question, a simple model of (im-) perfect household and worker mobility is employed. The focus of the analysis is on the efficient use of land and the...

We study optimal nonlinear income taxation when earnings can differ because of both ability and luck, so the income tax has both a redistributive role and an insurance role. A substantial literature on optimal redistribution in the absence of uncertainty has evolved since Mirrlees' original...

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 provides an efficiency argument in favour of progressive labour income taxation. When the consumer faces a trade-off between investments in financial and human capital, a proportional comprehensive income tax tends to discriminate in favour of human capital investments. This effect is...
