Coordinated Work Schedules and the Gender Wage Gap
(with Chinhui Juhn and Pedro Silos) Download Paper

Married women with kids that are full time workers work less and allocate more time to home production than their men counterparts. At the same time the labor market is characterized by occupations that differ in terms of the coordination of the work schedules. Workers that work in occupations that concentrate hours at peak times of the day are paid a higher wage, but relatively lower if they are women. The higher demand for family time women face restricts their occupational choice and thus drives a gap in their earnings relative to men. We incorporate these trade offs in an occupation choice model with home production in which workers have comparative advantages to work into different occupations. In the model, labor supply, the supply of family time and the occupational choice are intimately related. The effect of differences in household care responsibilities between men and women in their occupational choice explain half of the observed gender earnings gap.


Social Insurance and Occupational Mobility
(with Pedro Silos) Download Paper

By experimenting in the labor market, workers find their best occupational fit in a process filled with uncertainty. If workers are risk averse and there is limited earnings insurance, workers may remain in unfitting occupations when better matches are available. We propose a dynamic assignment model with incomplete markets to illustrate how social insurance policies encourage experimentation, leading to a better matching of workers to occupations. We estimate the model using microdata from the United States and Germany. Higher earnings uncertainty explains the United States higher mobility rate. Allowing workers in the United States to enjoy Germany’s degree of social insurance leads to even more mobility and experimentation. Output and welfare gains are large.


Lack of Infrastructure?: Public Capital and Economic Development
Download Paper

This paper offers new evidence on the sources of cross-country income differences by investigating the role public capital in economic development. For a sample of 90 countries it first documents that public capital represents, on average, a third of the total capital stocks. In addition, it greatly varies across countries and it is negatively correlated with output per worker. I develop a methodology that links production functions with national accounts data that allows to measure the contribution of both public and private capital stocks to output. If public capital is a pure public good and it is a complement of private capital, compared to the standard accounting exercise, differences in factor of production can account for more than double of the observed cross-country variation in income per worker.
