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 find out whether the lack of proper incentives to improve performance has resulted in the low TFP...

This study estimates cost inefficiency and economies of scale of Slovenian water distribution utilities over the 1997-2003 period by employing several different stochastic frontier methods. The results indicate that significant cost inefficiencies are present in the utilities. An introduction of incentive-based price regulation scheme might help resolve this problem. However, the inefficiency...

Efficiency and regulation of the Slovenian electricity distribution companies

The Slovenian Energy Law, adopted in 1999, has opened the internal market to competition up to 64% of the final consumption. The opening of the internal market to foreign competition is envisaged for 2003. With regard to the methodology of price regulation, the Energy Law introduces the “price-cap” regulation, which aims to give firms incentive for cost reduction. To provide information for...
