英文文献：Impact of a Cost Minimisation User Cost Model on Public Transport Subsidy-成本最小化用户成本模型对公共交通补贴的影响
英文文献作者：Peter Tisato
英文文献摘要：
We show that optimal public transport subsidy is sensitive to the use of alternative user cost models, and that a model based on cost minimisation principles may lead to an improvement in subsidy estimates. For the case of homogeneous consumers and non-peaked demand, the cost minimisation user cost model yields optimal subsidy estimates which differ by up to 55% from those generated by existing'models. Multiple optimal subsidy equilibria may also exist arising from a kink in the user cost schedule at a critical frequency and a resulting discontinuity in the marginal benefit of frequency enhancement schedule
我们发现，最优的公共交通补贴对使用其他用户成本模型很敏感，而基于成本最小化原则的模型可能会改善对补贴的估计。对于同质消费者和非峰值需求的情况，成本最小化用户成本模型产生的最优补贴估计与现有模型产生的估计相差高达55%。用户成本计划在某一临界频率上的扭结和频率增强计划边际效益的不连续性也可能导致多个最优补贴均衡
