A number of existing studies have concluded that risk sharing allocations supported by competitive, incomplete markets equilibria are quantitatively close to first-best. Equilibrium asset prices in these models have been difficult to distinguish from those associated with a complete markets...

We find that returns to occupational tenure are substantial. Everything else being constant, 5 years of occupational tenure are associated with an increase in wages of 12%-20%. Moreover, when occupational experience is taken into account, tenure with an industry or employer has relatively little...

We document and analyze the high level and the substantial increase in worker mobility in the United States over the 1968-97 period at various levels of occupational and industry aggregation. This is important in light of the recent findings that human capital of workers is largely occupation-...

There is a negative mean-dispersion relationship between the log of mean annual hours in an occupation and the standard deviation of log annual hours in that occupation. We document this pattern using data from the 1976-2011 Current Population Survey (CPS) and various Survey of Income and...

This paper studies the role of social security and tax and transfer programs for understanding cross-country differences in labor supply late in the life cycle. First, we use the Survey of Health, Ageing, and Retirement in Europe (SHARE) as well as the U.S. Health and Retirement Study (HRS) to...

This paper studies the quantitative implications of wealth taxation (as opposed to capital income taxation) in an incomplete markets model with return rate heterogeneity across individuals. The key source of heterogeneity comes from the fact that some individuals have better entrepreneurial...

There is a negative mean-dispersion relationship between the log of mean annual hours in an occupation and the standard deviation of log annual hours in that occupation. We document this pattern using data from the 1976-2011 Current Population Survey (CPS) and various Survey of Income and...

This paper examines the role of relationship skills in determining life cycle outcomes in education, labor and marriage markets. We posit a two-factor model with human capital and "relationship" or "partnering" skill. Relationship skill is understood in our framework as the ability to maintain...

We argue that standard models with one-dimensional skills and human capital cannot explain these distinct patterns. Instead we develop a model in which human capital is occupation-specific, but in which non-routine occupations require upfront occupation-specific human capital built-up....

We build a heterogeneous life-cycle model which captures a large number of salient features of individual labor supply over the life cycle, by education, both along the intensive and extensive margins. The model provides an aggregation theory of individual labor supply, firmly grounded on...
