Comparative study explores economic efficiency in railways, suggesting policies for improvement.
The productive efficiency of the railway systems in 19 OECD countries is analysed. The empirical results show that: (i) railway systems with high dependence on public subsidies are significantly less efficient than similar railways with less dependence on subsidies; (ii) railways with a high degree of managerial autonomy from regulatory authorities tend to achieve higher efficiency.
