Abstract
Household time-use patterns are expected to reflect each household member’s daily activity participation and duration with intra-household interactions constrained by multiple budgets. Among various activities, the allocated activity derived from undertaking a household task is studied relatively less in the literature. Who will take an allocated activity is a discrete choice problem of household task assignment, and once a household member is assigned with one household task, other members will have more time to do other activities. To better understand household time-use patterns affected by household task assignment, this paper proposed a joint household-level multiple discrete-continuous extreme value-multinomial logit (MDCEV-MNL) model with multiple constraints. The Karush-Kuhn-Tucker (KKT) method combined with the simulation-based maximum likelihood estimation method is proposed to estimate the proposed model. Based on the household activity-travel data from Beijing of China, the proposed model is customized to explore elderly couples’ time-use patterns with intra-household interactions affected by household task assignment. Following the findings, policy implications are suggested to build an age-friendly society.
Highlights
Population aging issues are significantly affecting the sustainability of economic development and society’s stability [1]
Since an allocated activity is derived from household task assignment, in order to have a better understanding of elderly couples’ time-use patterns, impacts of household task assignment should be incorporated into a household-level time-use model
Note that this paper only considers the scene that only one member is assigned to complete the ‘task’ when talking about household task assignment
Summary
Population aging issues are significantly affecting the sustainability of economic development and society’s stability [1]. Household time-use patterns refer to the participations and durations of daily activities for household members It is a multiple discrete-continuous choice problem, since each member may undertake more than one daily activity given a time budget. Behaviors and decision-making processes behind household time use and task assignment for elderly couples in China are different, compared with other countries, due to the incomplete social welfare and public service as well as the traditional Chinese family values [7]. This paper will shed light on developing a joint model of household time use and task assignment with intra-household interactions and multiple constraints to explore impacts of household task assignment on elderly couples’ time-use patterns in Beijing, China.
