Assuming a two-period model with endogenous choices of labour, education, and saving, it is shown to be second-best efficient to deviate from Ramsey's Rule and to distort qualified labour less than nonqualified labour. The result holds for arbitrary utility and learning functions. Efficient...

Assuming a two-period model with endogenous choices of labour, education, and saving, it is shown to be second-best efficient not to distort the choice of education. In general this implies distorting the saving decision. Hence a strict order of policy priority is derived. Efficient tax policy...

Tax competition between two governments who choose nonlinear income tax schedules to maximize the average utility of its residents when skills are unobservable and labor is perfectly mobile is examined. We show that there are no Nash equilibria in which there is a skill type that pays positive...

We examine how allowing individuals to emigrate to pay lower taxes abroad changes the optimal non-linear income tax scheme in a Mirrleesian economy. An individual emigrates if his domestic utility is less than his utility abroad net of migration costs, utilities and costs both depending on...

We derive a general optimal income tax formula when individuals respond along both the intensive and extensive margins and when income effects can prevail. Individuals are heterogeneous across two dimensions: their skill and their disutility of participation. Preferences over consumption and...

Previous literature has shown that public provision of private goods can be a welfare-enhancing 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...

This paper considers the optimal taxation of savings intermediation and payment services in a dynamic general equilibrium setting, when the government can also use consumption and income taxes. When payment services are used in strict proportion to final consumption, and the cost of...

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...
