Efficiency of the Portuguese metros. is it different from other European metros?


This research analyses the performance of Portuguese metros in the European context. By means of two non-parametric benchmarking techniques, respectively performance indicators and data envelopment analysis, we compute the efficiency of 37 European metros. In order to provide statistical inference and robustness to our results we apply the recent technique of bootstrap. We also use the partial frontiers (order-m) to identify outliers and the double bootstrap procedure in a second stage methodology to take into account the influence of the operational environment. The results show important levels of inefficiency both in the Portuguese metros and in other European metros.Metro; Efficiency; Portugal; Performance Indicator; Data Envelopment Analysis
