Marriage, specialization, and the gender division of labor

We consider why the gender division of labor is so often enforced by custom and why customary gender divisions of labor generally involve both direction and prohibition. In our formal model, agents first learn skills and then enter the marriage market. We show that wasteful behavior may emerge due to strategic incentives in specialization choice and human capital acquisition and that both problems may be mitigated through a customary gender division of labor. This division is not Pareto improving. Both the distributional effects and welfare gains of a customary gender division of labor decrease as opportunities for market exchange increase.
