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...

A large empirical literature documents a rise in wage inequality in the American economy. It is silent on whether the increase in inequality is due to greater heterogeneity in the components of earnings that are predictable by agents or whether it is due to greater uncertainty faced by agents....

Many discrete life choices--where to live, what kind of job to hold, and consumption lifestyle--are stratified by income. Stratification and sorting often manifest state-dependent preferences in which the marginal utility of income (consumption) depends on the outcome of prior choices. For...

Earnings dynamics are much richer than typically assumed in macro models with heterogenous agents. This holds for individual-pre-tax and household-post-tax earnings and across administrative (Social Security Administration) and survey (Panel Study of Income Dynamics) data. We study the...

This paper presents a framework for the quantitative analysis of individual income dynamics, mobility and welfare, with ex-ante identical individuals facing a stochastic income process and market incompleteness implying that they are unable to insure against persistent shocks to income. We show...
