AUTOMOBILE USE AND LOCATIONAL INTERDEPENDENCIES
在城市单中心模型中同时纳入汽车使用的拥堵和污染外部性，分析它们如何影响家庭区位决策和城市结构，并通过模拟和敏感性分析揭示其作用机制。
ABSTRACT. Congestion and pollution externalities from automobile use are simultaneously included in an urban monocentric model. The externalities enter household utility functions directly, and result in a complex interdependency in household location decisions in the city. Implications of the model are drawn out by a simulation and complete sensitivity analysis. The two unpriced externalities are examined for their impact on urban structure, and contrasted with each other. Also, the effect of changes in speed of travel are examined for the impact on urban structure. Speed affects the level of both external effects, and is affected by location decisions.
