A Multiple Discrete-Continuous Model for Independent- and Joint-Discretionary-Activity Participation Decisions

Analysis of household interdependencies in activity-travel patterns is a growing area of research. This paper contributes to this analysis by examining solo and joint discretionary activity participation (time use) decisions. A multiple discrete-continuous econometric structure is used to model the daily time-investment decisions of couples in solo- and joint-discretionary activities incorporating intra-personal and inter-personal inter-dependencies. The empirical model was estimated using data from the 2000 Bay Area Travel Survey. The findings show evidence of the positive impact of vehicle availability on independent activity participation and the negative impacts of the presence of children and mandatory time investments on the joint discretionary-activity engagement of the spouses. In addition, results show that mandatory- and maintenance-activity-participation characteristics of the spouse influence the discretionary activity choices of individuals. The analysis also indicates a strong impact of common unobserved factors on the decisions of couples. Overall, these findings underscore the importance of explicitly incorporating intra-household interdependencies in transportation policy evaluations.
