Occupational specificity of human capital motivates an important role of occupational reallocation for the economy's response to shocks and for the dynamics of inequality. We introduce occupational mobility, through a random choice model with dynamic value function optimization, into a...

I structurally estimate an incomplete markets lifecycle model with endogenous labor supply, using data on the joint distribution of wages, hours and consumption. The model is successful at matching the evolution of both the first and second moments of the data over the lifecycle. The key...

I structurally estimate an incomplete markets life-cycle model with endogenous labor supply using data on the joint distribution of wages, hours, and consumption. The model is successful at matching the evolution of both the first and second moments of the data over the life cycle. The key...

We study a minimal model of automation in which, in the limit, labor is replaced by capital in all tasks. If tasks are gross complements and automation is sufficiently slow, the labor share remains strictly positive despite an endogenous reduction in hours worked and full automation in the...

Based on Panel Study of Income Dynamics (PSID) and Consumer Expenditure Survey (CEX), the author presents evidence that the rise of income/consumption inequality over the past decades is more significant among younger households. This is consistent with the theory that the secular rise of...

In this paper, I present a theory of dynamic economic growth, business cycles, and asset pricing that integrates (1) Marx's idea (and emphasized by Klein) of a two-class heterogeneity of the ownership structure of physical capital and human capital in a capitalist society, (2) Keynes' idea of...

The paper studies how high household leverage and crises can arise as a result of changes in the income distribution. Empirically, the periods 1920-1929 and 1983-2008 both exhibited a large increase in the income share of high-income households, a large increase in debtleverage of the remainder,...

This paper quantifies the impact of borrowing constraints on consumption and earnings inequality in a life-cycle model with labor market search and endogenous human capital accumulation. I first show that following an unemployment spell, likely-constrained workers in the Survey of Income and...

This paper analyses the level of inequality in Spain and how it evolved over the course of the past crisis and the early stages of the current recovery. To this end, it first introduces the various dimensions of wage, income, consumption and wealth inequality, and studies how they have...

Idiosyncratic labor incomes are typically modeled either by stochastic processes with heterogeneous income profiles (HIPs) or restricted income profiles (RIPs). The HIP assumes that individual labor income grows deterministically at an unobserved rate and contains a persistent but stationary...
