Existing studies have shown that decision of activity participation and time allocation behaviors are interdependent. This study reconfirms this finding using a Japanese national time use data collected in 2001 by developing a joint discrete-continuous time allocation model to represent the interactions between activity participation and time use behaviors over the course of a day. A binary logit model is adopted to describe activity participation behavior, while a utility-maximizing time allocation model is established to calculate the time allocated to each activity. The estimation results show that personal attributes, household attributes, and external environment attributes have a significant impact on activity decision. The negative parameter for the above interaction suggests that competition of time allocation occurs across activities. Furthermore, it is also confirmed that individuals try to allocate available time on different activities equally in order to increase his/her utility.
