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 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...

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...

During the last decade, Argentina has faced an extended process of reform of the Pension System. It had been implemented a mixed system with a private funds scheme (PFS) and a new public pay-as-you-go system. The PFS was based on personal contributions; it addressed the effect of demographic...

“High-power” regulatory regimes were adopted in most of the reformed electricity distribution sectors. In particular, in a price cap regime with a RPI-X rule, it is commonly used a benchmarking exercise based on efficiency frontier estimations to determine X factors. DEA is a widely used...

In this paper, it was made an exhaustive survey of the literature related with cost and production frontiers in the water and sanitation sector. The survey shed light in order to determine the variables to choose in the model to be estimated in a further empirical estimation developed for the...

Following the process initiated by Chile in the early 1980s, most countries in South America have undergone deep transformations in their electric industries. In this new playing field, the comparison of the relative efficiency of several regional monopolies seems to be a potentially valuable...

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...

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...
