| Summary | This study tries to develop a mixed discrete/continuous demand model to analyze the characteristics of household’s decision behavior on the ownership and usage of automobiles and motorcycles. The ownership of auto and/or motorcycle are modeled as nested logit models while the amount of use are modeled as simultaneous regression models. Both models are derived from the same utility function to avoid possible biased estimation results. Empirical analysis indicated that the relation between the ownership of automobiles and motorcycles are not significant, but do exist between the mount of their use. And the degree of relationship in usage would decrease as more autos and/or motorcycles are available. For multi-car families, the relation among the use of individual auto are compliment, same findings for motorcycle. But the relation among the use of autos and motorcycles are substitute to each other. Simulation analysis indicated that the cost effect on the ownership of auto or motorcycle is not significant, but is quite significant on the use of them. |
