Almost all theoretical work on how to calculate the marginal deadweight loss has been done for linear taxes and for variations in linear budget constraints. This is quite surprising since most income tax systems are nonlinear, generating nonlinear budget constraints. Instead of developing the...

Several contributions in the optimal taxation literature have emphasized that, when individuals’ preferences are not separable between leisure and other goods, it is desirable to supplement a nonlinear income tax with public provision of private goods. Moreover, it has also been shown that the...

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...

In this paper, we consider how the retirement age as well as a tax financed pension system ought to respond to a change in the standard deviation of the length of life. In a first best framework, where a benevolent government exercises perfect control over the individuals’ labor supply and...

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...

We investigate how the optimal nonlinear income tax schedule is modified when taxpayers can evade taxation by emigrating. We consider two symmetric countries with Maximin governments. Workers choose their labor supply along the intensive margin. The skill distribution is continuous, and, for...

We utilise repeated cross sections of micro data from several countries, available from the Luxembourg Income Study, LIS, to estimate labour supply elasticities, both at the intensive and extensive margin. The benefit of the data is that it spans over four decades and includes a large number of...
