The main purpose of this paper is to analyze technical change in the electricity distribution sector in South America, in the period 1994-1997. We do so by estimating a Maximum Likelihood stochastic frontier. We found that there is no evidence of catching up effects in the sector during this...

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...

This paper deals current developments and the problems of regulation in European electricity in general and -in somewhat more detail-, England and Wales in particular.

The competitive structure of the telecommunication sector is changing all over the world. Competition is being introduced in the long-distance segments while the local markets remain in general under the control of a (group of) regulated monopolies. This paper tries to find the optimal...

The economics rates of return for utility privatization projects in Argentina are very high, wheter or not distributional weights are considered. But there is a very high shadow price for regulatory activity, which tends to be ignored in most privatization exercises. And how serious a government...

The sustainability of service is one of the fundamental aims of any regulatory system, and this tends to be reflected in the general principles within the legal framework of each public service. The necessity to cover economic costs of service then follows, in order to cover costs in such a way...

We estimate the Marginal Cost of Public Funds for Argentina using a computable general equilibrium (CGE) model, assessing the sensitivity of the results to the existence of alternative regulatory regimes (Price-Cap and Cost-Plus) for public utilities subject to regulation. Although the estimates...

The main goals of this paper are basically two: to compare the relative efficiency of the firms in the electricity distribution sector in South America, and to perform a consistency analysis on the different approaches usually used to measure efficiency. The estimated model considers a single...

The traditional Ramsey pricing and the Efficient Component Pricing Rule for access charges to a facility are modified in this paper, taking into account the constraint that profits per unit of investment must be the same between entrants and the incumbent (a general equilibrium requirement). It...
