This study derives and estimates models for the work travel time of each spouse in the household conditional on both spouses' hours of work. The model is estimated using Swedish household data. The own labour supply has a positive impact on travel time for females and a negative one for males. The estimated effects of the other spouse's labour supply are insignificant. An overall test of whether the hours of work are weakly separable from work travel time indicates that this hypothesis cannot be rejected for males but can be rejected for females.
