The aim of this study is to estimate both stochastic and mathematical programming cost functions and frontier studies with the ADERASA’s database. ADERASA is a Latin American association of water regulators, which has done a systematic effort on data collection. Econometric and DEA techniques...

The paper develops a cost frontier model of gas distribution and estimates it on data for gas distribution companies of Argentina. Efficiency measures are an important tool for regulators, showing how much a firm can rise its output without using more inputs. In Argentina, the Regulatory...

The purpose of this paper is to study the existence of differences in costs between pension fund administrators (PFAs) through the estimation of an econometric cost frontier for Argentina. Like in other eleven Latin American, and some other Central Asian and Eastern Europe countries, the social...

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...

In this paper we develop a model to understand the interactions between optimal regulation and external credit constraints. If a big proportion of the regulated sector is owned by foreign investors, a credit-constrained country who wants to send profits abroad has to generate enough surplus in...

There is a growing recognition of the importance of competition for the success of market economies, and of the need for government action both to maintain competition and to regulate industries where competition remains limited. In the area of telecommunications, upon which I shall focus today,...

Political and regulatory risks, cause damage to countries and investors because of investment diminishing. When investments take place, those could increase services prices. Present work has as its objectives to characterize theoretically the problem, to study existent measures to face it, to...

Worldwide privatization of the telecommunications industry and the introduction of competition in the sector, altogether with the ever-increasing rate of technological advance in telecommunications, raise new and critical challenges for regulation. For matters of pricing, universal service...

Regulators must understand basic principles of regulation, to explain with credibility their decissions, to asess the universality of the proposals, to develop new solutions, etc. For the relevance of economic theory, economists must fight to include in their frameworks enough constraints, as...

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...
