This paper examines a dynamic model of nonlinear income taxation in which the government cannot commit to its future tax policy, and individuals are quasi-hyperbolic discounters who cannot commit to future consumption plans. The government has both paternalistic and redistributive objectives,...

This paper addresses the question as to whether it is optimal to use separating or pooling nonlinear income taxation, or to use linear income taxation, when the government cannot commit to its future tax policy. We consider both two- period and inÖnite-horizon settings. Under empirically...

It has recently been shown that incorporating "keeping up with the Joneses" preferences into a prototypical two-ability-type optimal nonlinear taxation model leads to higher marginal income tax rates for both types of agents. Specifically, the high-skill type faces a positive marginal income tax...
