本文利用空间模型分析了弹性需求下可消化高速公路的第一和第二最佳政策、私有化和垂直分解的影响。本文还利用模拟方法分析了统一收费约束的福利成本。结果表明，除其他外，社会最优要求的边际成本的高速公路扩建等于净消费者利益的边界，而在第二个最好的情况下，总用户成本必须衡量的影子价格。反过来，利润最大化的公司等于边际扩展成本的加价收入在边界。
This paper uses a spatial model to analyse first- and second-best policies, impacts of privatization and vertical disintegration of a congestible highway with elastic demand. The paper also uses simulation methods to analyse the welfare cost of a uniform-toll constraint. Results show, inter alia, that the social optimum requires the marginal cost of highway extension to be equal to the net consumer benefit at the boundary, while in the second-best case the aggregate user cost must be measured in terms of the shadow price. In turn, a profit-maximizing firm equates the marginal extension cost to the markup revenue at the boundary.
