Why are Married Men Working So Much?

We document a negative trend in the leisure of men married to women aged 25-45, relative to that of their wives, and a positive trend in relative housework. We develop a simple bargaining model of marriage, divorce and allocations of leisure-time and housework. Calibration to US data shows the trend in the wage gender gap explains most of the trend in relative leisure, but has little effect on married women's labor supply, which appears to be due mainly to the trend in the price of home equipment.
