We study the impact of endogenous longevity on optimal tax progressivity and inequality in an overlapping generations model with skill heterogeneity. Higher tax progressivity decreases both the longevity gap and net income inequality, but at the expense of lower average lifetime and lower...

In order to design optimal policy instruments that shape the distribution of income we require realistic income models. A comparison between popular stochastic processes for income shows that most of them fail to match inequality in the US, especially at the top. The Geometric Brownian Motion...
