  • Co-author of National Bureau of Economic Research report, "Marry Your Like: Assortive Mating and Income Inequality."
  • His research has focused on how technological progress has impacted the economy. Other work has focused on how improvements in contraception have changed culture.


"The study shows that in a world where there are large differences in the incomes that people of different educational levels may earn, there is a marked tendency for individuals to marry people with the same educational background. Whatever the reason, this assortive mating increases income inequality across American households."
