This paper aims to analyse the price regulation method and performance of the water industry in Slovenia. A stochastic cost frontier model is employed to estimate and decompose the total factor productivity (TFP) growth of water distribution utilities in the 1997-2003 period. The main goal is to...

This paper contributes to the current, lively debate on which factors induce or hinder the deployment of next generation networks (NGNs), where regulatory design plays the key role. As a country with one of the highest levels of fibre deployment, intense infrastructural competition in urban...

The aim of this study is to analyze the scale and cost inefficiencies in operation for the Swiss regional bus companies. For this purpose,we have considered estimation of a stochastic and a deterministic frontier cost model for a sample of 93 bus companies in 1989. The estimates of inefficiency...
