Towards a simplified performance-linked value for money model as a reference point for bus contract payments

The burgeoning commitment to contracting the delivery of bus services through competitive tendering or negotiated performance-based contracts has been accompanied by as many contract payments schemes as there are contracts. We are now well placed to design a simplified performance-linked payment (SPLP) model that can be used as a reference point to ensure value for money, given the accumulation of experiences throughout the world which have revealed substantive common elements in contracts. Whether the payment to the operator is framed as a payment per passenger or as a payment per service kilometre, the SPLP identifies efficient subsidy outcomes that are linked to a proxy indicator of net social benefit per dollar of subsidy. We illustrate how the SPLP model can be applied to obtain the gross (subsidy) cost per passenger (or per passenger km) from measures of gross cost efficiency and network effectiveness. This model can then be used as part of a benchmarking activity to identify reference value of money prospects in respect of passengers per $ subsidy outlay by adjusting for influences not under the control of the service provider. A single framework to identify contract payments to operators, and to assess (i.e., benchmark) operator performance on critical KPIs, is provided by internalising critical key performance indicators (KPIs) in the design of the SPLP. The proposed SPLP model is sufficiently general to be independent of the procurement method (competitive tendered or negotiated, for example) and of the treatment of revenue allocation (net or gross based contracts), with the additional advantage of being able to assess value for money for government.     

南京市公交企业补贴机制研究与分析

城市公共交通经营亏损是一个不争的事实,研究公共交通合理补贴是一个迫切需要解决的问题。本文在对公共交通经营方式分析的基础上,结合南京公交集团经营情况分析,提出以成本补偿为依据,改进完善公交补贴机制,合理确定补贴额,拓宽对公交政策性亏损的补贴来源渠道。同时,借鉴台北市对公共交通的经济补贴政策及相关的评价制度,将行风评议结果纳入考核指标体系。呼吁政府在加大资金补贴的基础上,进一步落实公交优先政策,从政策、规划等方面予以支持,改善公交企业的经营环境,推动公共交通事业的平稳健康发展。     

保价运输与运输保险的竞合关系研究

A meta-analysis of Western European external costs estimates

This paper analyses the external transport cost estimates that have been found in various European studies. These estimates seem at first glance to be highly dispersed, a fact which raises questions about their reliability. The article offers a list of the possible reasons for discrepancies between the various studies; differences in the specific situations studied, in the type of cost calculated, in the physical laws relating to emissions, in the measurement of values of external costs. It assesses the relative magnitude of each of these causes through a meta-analysis. It turns out that the main differences come from the specificity of the situation under review and the type of cost calculated. In comparison, differences in the laws and in the values methods have a lower importance. The conclusion is that the estimates of external costs are reliable for decision-making policies.
