Over time, productivity and education have increased, while hours worked have not. Cross-sectionally, higher-wage individuals have more schooling, more hours worked in the market, fewer hours worked at home, and a lower variance of market hours. Over the life cycle, older individuals have higher wages, more hours worked both in the market and at home, a lower variance of market hours, and almost the same amount of education as younger agents. These and other facts are documented, and a simple overlapping-generations model with skill acquisition and home production that delivers most of these properties is constructed.
