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...

With the data of 831 Japanese water utilities from 1999 to 2008, we used the stochastic cost frontier analysis with a true fixed-effect model in order to estimate the cost efficiency and scale economies. We found that cost inefficiency was approximately 37%. The economies of water delivery...

This paper is devoted to examining the scope, outcomes and shortcomings of reforms aimed at introducing competition in the production, transport, distribution and retail segments of the gas industry. The experiences of Argentina, Colombia and Mexico are used as examples. The paper includes the...

The paper deals with selected issues prevalent in the environment of regulated gas distribution. Regulation which ensures for investors an up-front known rate of return lead in valuation of an individual investment projects to obstacles we do not meet in other fully liberal markets. Solution of...

Flow maldistribution through the cell package affects the efficiency of the fuel cells, thus limiting the reliability and the diffusion of such a technology. This subject is a key-point in the progress of the fuel cells, so deserving the greatest attention and the most thorough research. This...

Natural gas can be used for satisfying population needs for heating, either directly by bringing the gas to the dwellings through the gas distribution system and combusting it in the domestic boiler (gas distribution system—G) or indirectly by combusting the natural gas in the heating plant...
