Random Utility-Based Microeconomic Model for Discretionary Activity Time Allocation
No full textThis paper proposes a microeconomic model for activity time allocation analysis that recognizes the random nature of daily time allocation, while also focusing on activities as a direct source of individual utility. More specifically, different levels of satisfaction (or utility) are gained from activity participation depending on the amount of time allocated to and the type of goods utilized in daily activities. The proposed model represents individual utility as a function of activity participation, accounts for the budget constraint in activity time allocation, allows for the interindividual and interactivity variation of utility, and considers the entire sphere of discretionary activities (in-home as well as out-of-home activities and trips). The aim of this study is to show how including a budget constraint in random utility models avoids overestimating the times allocated to activities and trips estimated by earlier random utility-based models that consider only time constraints. In particular, estimates of in-home and out-of-home discretionary activity and trip times for a sample of Italian single individuals from the 2003 National Institute of Statistics (ISTAT) Time Use Survey are presented. Compared with the estimates obtained using the simply time-constrained model with no budget constraint, the empirical findings show the variable effects to be interpreted in the same way. A greater number of significant variables in the double-constrained model denote greater complexity of the phenomenon to be represented. Incorporating the budget constraint diminishes the effect of some variables on activity time allocation

A model of the dynamic process of time allocation to discretionary activities
No full textThis paper proposes an activity-based methodology for representing the allocation of time to discretionary
activities during their programming and scheduling, based on the premise that both phases are to be considered
contextually and two aspects of the same decision process. The aim of this work is to extend the treatment
of utility maximization associated with carrying out two activities to J activities, so as to be able to segregate
the time spent traveling from the total amount of time dedicated to out-of-home activities. The global structure
of the model takes the form of a nested Tobit, particularly suited for reproducing a sequence of coupled
choices. The first choice concerns dividing up overall discretionary time between activities inside and outside
the home, then the second choice, subordinate to the first, involves rebudgeting the time between in- and outof-
home activities and trips. Thus the proposed model enables us to analyze the effects that each explicative
variable exerts on trips segregated from activities outside the home and, last, during demand forecasting, the
direct consequences of allocating discretionary time to trips following changes to an individual’s time budget.
A database created from a large-scale time-use survey (ISTAT 1988–1991) has been used for calibrating the
model coefficients
