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...

In this paper we propose a general approach for estimating stochastic frontier models, suitable when using long panel data sets. We measure efficiency as a linear combination of a finite number of unobservable common factors, having coefficients that vary across firms, plus a time-invariant...

The purpose of this study is to analyze the cost efficiency of electricity distribution systems in order to enable regulatory authorities to establish price- or revenue cap regulation regimes. The increasing use of efficiency analysis in the last decades has raised serious concerns among...
