The Role of Preferences and Opportunity Costs in Determining the Time Allocated to Housework
利用2000-01年英国时间使用调查数据，研究夫妻在家务（洗衣、熨烫、清洁、食品购物）上的时间分配，发现妻子的机会成本影响更大，而丈夫的偏好作用更显著。
Research on intrahousehold time allocations has assumed that housework is a necessary evil and focused exclusively on the causal role of opportunity costs. In fact, agents likely act to maximize happiness, and preferences regarding even mundane household chores differ considerably. I use information from the 2000-01 UK Time Use Survey to examine time spent on laundry, ironing, cleaning, and food shopping. Joint multivariate analysis of his and her time on weekend and weekday days as well as maid service reveals that her opportunity cost of time matters more than his, but that his preferences play a greater role than hers.
