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...

What structure of income taxation maximizes the social benefits of redistribution while minimizing the social harm associated with distorting the allocation of labor input? Many authors have advocated scrapping the current tax system, which redistributes primarily via marginal tax rates that...

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...

We document a strong negative relation in the United States between wealth and aggregate volatility. For example the 1970s and the late 2000s were periods of low asset values and high volatility. The early 1960s and the Great Moderation of the 1980s and 1990s were periods of high asset values...

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...

We first document a strong negative correlation between the level of household net worth, and aggregate business cycle volatility over the past 50 years in the United States. The early 1960s and the Great Moderation of the 1980s and 1990s were periods of high asset values and low volatility. The...

This paper offers a quantitative exploration of optimal income tax design in the Mirrlees tradition, and asks how nearly simple parametric tax functions can decentralize constrained efficient allocations. The environment features both observable and unobservable components of idiosyncratic labor...

This paper is structured in three parts. The first part outlines the methodological steps, involving both theoretical and empirical work, for assessing whether an observed allocation of resources across countries is efficient. The second part applies the methodology to the long-run allocation 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...
