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 study analyzes the structure of the water industry in Peru. It investigates economies of scale and cost inefficiencies in 43 water providers during the years from 1996 to 2005. Different water sources in different geographical regions directly affect the production technology of the sector,...

Este estudio analiza los determinantes de la productividad total de los factores de los bancos españoles desde el año 2000 hasta el período poscrisis. En particular, analizamos los cambios en la productividad derivados del proceso de reestructuración que ha experimentado el sector bancario...

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...
