Railway reforms: do they influence operating efficiency? 总被引:1,自引:0,他引:1
This paper considers railway operations in 23 European countries during 1995–2001, where a series of reform initiatives were
launched by the European Commission, and analyses whether these reform initiatives improved the efficiency of the railway
systems. Efficiency is measured using Multi-directional Efficiency Analysis, which enables investigation of how railway reforms
affect the inefficiencies of specific cost drivers. The main findings are that the reform initiatives generally improve technical
efficiency but potentially differently for different cost drivers. Specifically, the paper provides empirical evidence that
accounting separation is important for improving the efficiency in the use of both material and staff costs, whereas other
reforms only influenced one of these factors.

Measuring inefficiency in the Norwegian bus industry using multi-directional efficiency analysis 总被引:2,自引:1,他引:2
This paper deals with methods of measuring and analyzing efficiency in the transport industry. The aim of the paper is to introduce and demonstrate the advantages of Multi-directional Efficiency Analysis (MEA) in the case of cost data with limited substitution possibilities. For this purpose we reconsider the Norwegian bus data that has previously been analyzed using econometric models and Data Envelopment Analysis; Jørgensenet al. (1995, 1997) and Odeck and Alkadi (2001). It is shown how, using MEA, it becomes possible to disaggregate inefficiency into different components corresponding to different types of cost generating variables and thereby providing both managers of the bus companies and policy makers with more detailed information on possible improvements in performance. 相似文献
