The compensated taxable income elasticity at a given income level is proportional to the number of individuals who bunch at a convex kink point. This holds true even in the presence of optimization frictions if the jump in marginal tax rates is suciently large. In this paper we estimate bunching...

Using a calibrated overlapping generations model we quantify the welfare gains of an age dependent income tax. Agents face uncertainty regarding future abilities and can by saving transfer consumption across periods. The welfare gain of switching from an age-independent to an age-dependent...

Previous literature has shown that public provision of private goods can be a welfareenhancing 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...

In a recent paper Alesina et al. (2011) construct a model in which different labor supply elasticities for men and women emerge endogenously from intra-household bargaining. In this paper I explore the optimal tax implications of their model in an economy with both singles and couples and...

In this paper I perform numerical simulations of the discrete model of optimal income taxation employing a large number of taxpayer types. Moreover, I indicate how the results depend on the number of types used to represent the wage distribution. Finally, I compare simulations of the continuous...

The Mirrlees Review recommends that commodity taxation should in general be uniform, but with some goods consumed in conjunction with labour supply (such as child care) left untaxed. This paper examines the validity of this claim in an optimal income tax framework. Contrary to the recommendation...

In this paper we allude to a novel role played by the non-linear income tax system in the presence of adverse selection in the labor market due to asymmetric information between workers and firms. We show that an appropriate choice of the tax schedule enables the government to affect the wage...
