This paper presents a model for the joint household decision on carownership and car use. The model is explicitly based on the microeconomic theoryof consumer behavior, in which the fixed and variable car costs are two maincomponents of budget restriction. A household is assumed to maximize its utilityfunction with two goods: annual kilmetrage in the first car and other goods. Thenon-linear forms of likelihood functions used in this paper are muchsophisticate and realistic. In the end of this paper, micro-simulations arecarried out to investigate the impact of changes in variable car costs, fixedcar costs, income, and combinations of these on car ownership and use. |
