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...

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...

In this paper we analyse the cost structure of a sample of Italian Local Public Transport (LPT) companies operating in large urban centres, so as to extend the evidence of some recent studies focused on small-sized and medium-sized operators. The main focus is to verify the presence and the...

In this paper we estimate cost efficiency and technological characteristics of public hospitals in Piemonte over the period from 2000 to 2004. During the Nineties, different regulatory reforms aiming at controlling health expenditure affected the Italian National Health Service, ranging from the...

The aim of the present study is to provide fresh evidence about the characteristics of cost structure of public transit systems in Italy. The analysis is carried out by comparing the productive performance (average costs and productivity) of small, medium and large-sized companies providing both...
