Abstract
This paper examines how the introduction of unilateral divorce affects assortative mating and household income inequality across newly married couples. I exploit variation in the adoption and timing of unilateral divorce laws using three different empirical methods. I find that unilateral divorce increases income inequality by 3.5--16%. This is likely driven by increased assortative mating---unilateral divorce moderately increases educational sorting and substantially increases income sorting. The increased assortative mating could be partially driven by reduced marriage entry among college graduates and changes in women’s labor force participation at the time of marriage.
