We use time-diary data on couples with children from the 2000 United Kingdom Time Use Survey to examine the impacts of own and partner’s wages on parents’ provision of child care and market work on weekdays and on weekends and holidays. We find that increases in partners’ wages increase women’s primary care on all days and decrease their market work on weekdays, while increases in women’s own wages increase their market work on weekdays. In contrast, men’s time use is only responsive to their own wage on weekend days, when they reduce their market time and increase their primary child care time in response to higher wages.
