We explore the optimal progressivity of the income tax system in an incomplete-markets model. Agents value private and public consumption and leisure, and are heterogeneous with respect to innate ability, idiosyncratic shock histories, and preferences. This heterogeneity generates a potential...

uninsurable wage risk, insurable wage risk, and measurement error.

In this paper, we study the impact on the aggregate economy of changes in individual risk and insurance. To this end, we use the analytical framework developed in Heathcote, Storesletten and Violante (2008). Our main finding is that insurable risk increases TFP by improving the allocation of...

This paper studies consumption and labor supply in a model where agents have partial insurance and face risk and initial heterogeneity in wages and preferences. Equilibrium allocations and variances and covariances of wages, hours and consumption are solved for analytically. We prove that all...

We conduct a welfare analysis of redistributive labor taxation in a tractable heterogeneous-agents economy. We highlight four key considerations that determine the optimal overall progressivity of the tax schedule: (i) the preference weight on public consumption goods, (ii) the variance of...

What shapes the optimal degree of progressivity of the tax and transfer system? On the one hand, a progressive tax system can counteract inequality in initial conditions and substitute for imperfect private insurance against idiosyncratic earnings risk. At the same time, progressivity reduces...

We develop a model with partial insurance against idiosyncratic wage shocks to quantify risk sharing. Closed-form solutions are obtained for equilibrium allocations and for moments of the joint distribution of consumption, hours, and wages. We prove identification and demonstrate how labor...
