The core of the present study is to analyse the cost efficiency of public transit systems in Italy, investigating the way subsidization mechanisms and network characteristics affect the x-inefficiency levels of firms. The analysis uses a seven-year (1993-1999) unbalanced panel of 45 Italian...

The aim of this paper is to account for the impact of statistical noise and exogenous regulatory and environmental factors on the efficiency of public transit systems in a DEA-based framework. To this end, we implement a three-stage DEA-SFA mixed approach based on Fried et al. (2002) using a...

Empirical studies on the cost structure of Public Transit Networks are mainly based on specialized firms providing urban or intercity services. In this study we estimate a translogarithmic variable cost function to assess the behaviour of returns to scale and the impact of network...
