Equilibrium Tax Rates under Ex-ante Heterogeneity and Income-dependent Voting

Abstract

Abstract The standard models with incomplete markets (e.g. Aiyagari) have difficulty justifying the current income tax rates as an optimal or political equilibrium outcome. Given the highly skewed income distribution, the majority of the population would be in favor of raising taxes to a much higher level. We show that incorporating (i) the ex-ante heterogeneity of earnings and (ii) income-dependent voting behavior helps us to reconcile the large gap between the model and data.
