|April 2014||An Empirical Model of Wage Dispersion with Sorting|
with Rasmus Lentz: w20031
This paper studies wage dispersion in an equilibrium on-the-job-search model with endogenous search intensity. Workers differ in their permanent skill level and firms differ with respect to productivity. Positive (negative) sorting results if the match production function is supermodular (submodular). The model is estimated on Danish matched employer-employee data. We find evidence of positive assortative matching. In the estimated equilibrium match distribution, the correlation between worker skill and firm productivity is 0.12. The assortative matching has a substantial impact on wage dispersion. We decompose wage variation into four sources: Worker heterogeneity, firm heterogeneity, frictions, and sorting. Worker heterogeneity contributes 51% of the variation, firm heterogeneity contrib...
|June 2013||Education, Birth Order, and Family Size|
with Javier A. Birchenall, Hani Mansour, Sergio Urzúa: w19111
We introduce a general framework to analyze the trade-off between education and family size. Our framework incorporates parental preferences for birth order and delivers theoretically consistent birth order and family size effects on children's educational attainment. We develop an empirical strategy to identify these effects. We show that the coefficient on family size in a regression of educational attainment on birth order and family size does not identify the family size effect as defined within our framework, even when the endogeneity of both birth order and family size are properly accounted for. Using Danish administrative data we test the theoretical implications of the model. The data does not reject our theory. We find significant birth order and family size effects in individual...
