This paper examines the importance of ex-ante heterogeneity for understanding the relationship between wealth and labor supply when markets are incomplete. An infinite horizon model is estimated where labor supply is indivisible and households are ex-ante heterogeneous in their labor disutility...

This paper quantifies the macroeconomic implications of the lack of insurance against idiosyncratic labor market risk. I show that in a model economy calibrated to observed individual level data, households make ample use of work effort as a consumption smoothing mechanism. As a consequence,...

How does the persistence of earnings change over the life cycle? Do workers at different ages face the same variance of idiosyncratic earnings shocks? This paper proposes a novel specification for residual earnings that allows for an age profile in the persistence and variance of labor income...

This paper first establishes the empirical fact that over the last quarter of the 20th century, the average weekly hours worked increased for workers in the highest wage quintile while it decreased for the ones at the lowest. In 1976, a worker in the lowest quintile worked 2.8 hours more per...

We study the joint determination of gender differences in labor earnings and time devoted to home production in an economy where informational frictions give rise to incentive problems in the labor market. Our model generates novel predictions on the relation between earnings, home hours and the...

This paper makes three contributions: First, I construct annual time series of gross domestic investment and national saving in the U.S. for the 1897–1949 period using historical component series. I compare the qualitative and quantitative properties of the newly constructed series with the...

In this paper I analyze the effects of innovations in information technology on the mortgage and housing markets using a life-cycle model with incomplete markets and idiosyncratic income, as well as moving and house price shocks. I explicitly model the housing tenure choices of households....

I study the asset pricing implications and the efficiency of a tractable dynamic stochastic general equilibrium model with heterogeneous agents and incomplete markets along the lines of Krebs [Krebs, T., 2003. Human Capital Risk and Economic Growth. Quarterly Journal of Economics 118(2),...

We study the effects of credit shocks in a model with heterogeneous entrepreneurs, financing constraints, and a realistic firm-size distribution. As entrepreneurial firms can grow only slowly and rely heavily on retained earnings to expand the size of their business, we show that, by reducing...

In 2005, reforms made formal personal bankruptcy much more costly. Shortly after, the US began to experience its most severe recession in seventy years, and while personal bankruptcy rates rose, they rose only modestly given the severity of the rise in unemployment. By contrast, informal default...
