<i> Analisi dell'efficienza di scala e di costo delle compagnie di bus italiane e svizzere </i> (di Massimo Filippini, Michael Kuenzle) - ABSTRACT: In this paper we have examined the scale and cost efficiency of Italian and Swiss regional bus companies. For this purpose, we have used the estimation of...

The deregulation of the electricity industry is currently on the political agenda in many countries. In most countries, the deregulation of the sector is combined with a (re-) regulation of the electricity networks in most of the countries. In this paper, we analyze the costs structure of 59...

This paper evaluates cost and scale efficiencies of Switzerland’s regulated bus companies operating in regional networks. The adopted methodology can be used in benchmarking analyses applied to incentive regulation systems. Moreover, the estimations can be used to evaluate the bidding offers...

This paper studies the cost structure of gas distribution utilities in Switzerland. Three stochastic frontier models are applied to a panel of 26 companies operating from 1996 to 2000. Efficiency is assumed to be constant over time. The analysis highlights the importance of output...

This paper applies a number of stochastic cost frontier models to a panel data set and compares their ability to distinguish unobserved heterogeneity from inefficiency variation among firms. The main focus is on Greene's 2005 panel data model that incorporates firm-specific effects in a...

This paper evaluates cost and scale efficiencies of Switzerland's regulated rural bus companies operating in regional networks. The adopted methodology can be used in benchmarking analyses applied to incentive regulation systems. Moreover, the estimations can be used to evaluate the bidding...
