In this paper we use a stochastic frontier approach to analyse the technical change in the post-privatisation period in the gas distribution sector in Argentina. We found that there are both a catching up effect and a shift in the frontier that are showing that the sector as a whole improved its...

During the last years, there has been an increasing concern about the importance of competition policy as a mean to increase efficiency in the allocation of resources and the supply and variety of goods and services. Competition between firms provides powerful incentives for cost minimization...

In this paper we describe two of the most used distributions for the inefficiency term in a stochastic frontier: the Half Normal and the Exponential distributions. We then show that both distributions affect the skewness of the composite error term in different ways, which make the Exponential...
