Applying social marginal costs pricing to the road sector

This chapter, following the results of the case studies analyzed in the Enact project, will identify and analyze the implications of the possible application of SMCP in PPP’s in the road sector. The main issues analyzed include SMCP revenue formation and its ability to finance the PPP. The paper will focus on market and competition issues like: 1) the problems due to mispriced substitutes; 2) the interdependencies between the tolls and the capacity of different road infrastructures when these are competing for the same demand; 3) since short run social marginal costs do not repay for the investments costs (except in special cases), in the case tolls should cover also the investment costs this will lead to totally different pricing schemes between roads in a same area, with problem of demand shift toward cheaper existing infrastructures, therefore increasing the problem of cost recovery. The incentives caused by the introduction of prices based on SMC’s are also investigated.     

Applying social marginal cost pricing in rail PPPs: Present state, drawbacks and ways forward

The application of social marginal cost pricing (SMCP) in PPP's in the railway sector faces several challenges. We examine in detail the practical applicability of SMCP in railway PPPs from the perspectives of cost accounting and effectiveness of SMCP towards the allocative efficiency goal, addressing the likely drawbacks in conciliating the welfare objectives of SMCP with the objectives of project financing (cost recovery) and value for money that justify the realization of PPP's. To this end, we combine theoretical analysis with the observation of empirical results of a case study. We split the analysis per type of private service provision, which can be for service operation or infrastructure management. For infrastructure management, we recommend splitting the operator remuneration and the track access charges. For service operation, we argue that the correct decision on source of funding of the service operator should depend on the characteristics of the contract.

中美公路工程估算费用构成对比

美国各州公路与运输官员协会（American Association of State Highway and Transportation Officials,AASHTO）为国际公路领域最主要的标准化机构,其制定的指南为美国国家公路与运输协会的标准,国内目前鲜有相关译文及文献资料作为参考。随着我国对外承包工程规模不断扩大,在完成对AASHTO《Practical Guide To Cost Estimating, 1st Edition》（造价编制实践指南第一版）的翻译及研读的基础上,分别从计价模式、层次划分、估价方法等方面进行对比分析,为我国的工程造价体系国际化发展提供参考依据,以更好地适应海外市场需求。

非确定因素影响下离散时段公路施工区用户费用模型

分析了离散时段下高速公路施工区的交通状况, 通过离散施工时段, 比较了各时间段内施工区容量和交通需求的关系, 建立了各个时间段相应的用户费用计算模型。分析了高速公路施工区用户费用的非确定因素, 根据非确定因素的概率分布值, 通过蒙特卡罗模拟对用户费用的波动区间进行预测, 并以清连高速公路为例进行实例验证。计算结果表明: 应用提出的模型, 白天施工时段的用户费用均值为193 148 021元, 最大值与最小值分别为466 820 060、117 342 849元, 夜晚施工时段的用户费用均值为1 795 047元, 最大值与最小值分别为3 443 468、1 417 274元。提出的模型能更好地体现非确定因素的影响。
