We investigate the welfare consequences of the stark increase in wage and earnings inequality in the US over the last 30 years. Our data stems from the Consumer Expenditure Survey, which is the only US data set that contains information on wages, hours worked, earnings and consumption for the...

In a standard incomplete markets model with a continuum of households that have constant relative risk aversion (CRRA) preferences, the absence of insurance markets for idiosyncratic labor income risk has no effect on the premium for aggregate risk if the distribution of idiosyncratic risk is...

In all major industrialized countries the population is aging over time, reducing the fraction of the population in working age. Consequently labor is expected to be scarce, relative to capital, with an ensuing decline in real returns on capital and increases in real wages. This paper employs a...

In this paper we demonstrate that different incomplete markets models yield qualitatively distinct predictions about how consumption growth responds to declines and increases in earnings. Markets are either exogenously incomplete in that households can only trade a risk-free bond, subject to a...

This paper analyzes the quantitative role of idiosyncratic uncertainty in an economy in which rational agents vote on hypothetical social security reforms. We construct an Overlapping Generations economy in which individuals face idiosuncratic risk with respect to their labor productivity and...

This paper computes the optimal progressivity of the income tax code in a dynamic general equilibrium model with household heterogeneity in which uninsurable labor productivity risk gives rise to a nontrivial income and wealth distribution. A progressive tax system serves as a partial substitute...

We evaluate the asset pricing implications of a class of models in which risk sharing is imperfect because of the limited enforcement of intertemporal contracts. Lustig (2004) has shown that in such a model the asset pricing kernel can be written as a simple function of the aggregate consumption...
