We estimate the changes in US male labor market risk over the last three decades in a model of endogenous labor supply and job mobility. Across education groups permanent shocks to productivity have become more dispersed. Moreover, heterogeneity in pay across offered jobs has increased for...

When employers face a trade-off between growing large and paying low wages—that is, when they have monopsony power—some productive employers will decide to acquire fewer customers, forgo sales, and remain small. These decisions have adverse consequences for aggregate labor productivity....

When mobility between locations is frictional, a person's economic well-being is partially determined by her place of birth. Using a life cycle model of mobility, we find that search frictions are the main impairment to the mobility of young people in Spain, and these frictions are particularly...

This paper studies short-time work arrangements (ERTEs) when aggregate risk is partially sector-specific. In Spain, the Great Recession and the pandemic recession (aka the Great Contagion) can both be understood as being driven partially by large sector-specific shocks. However, the latter shows...

This paper quantitatively determines the asset limit in income support programs which minimizes consumption volatility in a lifecycle model with incomplete markets and idiosyncratic earnings risk. An asset limit allows allocating transfers to those households with the highest utility gains from...

We study workers' idiosyncratic earnings risk over the life-cycle using a German administrative data set. Positive and negative earnings shocks both contain a highly persistent component. The variance and average size of positive persistent shocks is decreasing over the life-cycle. The...

We study the relationship between employment growth and worker flows in excess of job flows (churn) at the establishment level using the new German AWFP dataset spanning from 1975–2014. Churn is above 5 percent of employment along the entire employment growth distribution and most pronounced...

US entrepreneurs typically work long hours in their firms and these hours form a large part of the firms' labor input. This paper studies the role of endogenous owner hours in shaping the wealth distribution among entrepreneurs. We introduce owners' endogenous labor supply into a model of...

The size of the public sector in terms of employment and compensation has a strong life-cycle dimension. We establish a quantitative partial-equilibrium life-cycle model with incomplete markets, private and public sectors, and risk-averse workers, and use it to (i) calculate three dimensions of...

Standard search models are unreliable for structural inference of the underlying sources of wage inequality because they are inconsistent with observed residual wage dispersion. We address this issue by modeling skill development and duration dependence in unemployment benefits in a random on...
