The purpose of this paper is to assess comparative efficiency in water and sanitation sector in Brazil. We run a Sthocastic Frontier Analysis model for a panel of 127 providers, covering more than 70% of urban population of the country. We search and find an explanation for cost efficiency, and...

We study the efficiency of the Argentine banking service after a crisis in 2001-2002. The financial system started in practice from zero and recovered jointly with the economy, but its productivity and average cost levels are stagnated since 2007. The analysis encompasses efficiency frontiers of...

Se miden las ganancias potenciales de eficiencia de cinco fusiones de bancos, producidas entre 2005 y 2011, analizándolas con la metodología de análisis envolvente de datos. Dadas las divergencias entre modelos de rendimientos constantes y variables, se testean rendimientos para discernir...

The objective of this paper is to analyze the efficiency of the water sector in Latin American countries. We try to find factors affecting efficiency rather than identifying which country or individual provider is more or less efficient. We also consider which model would be more fitting for the...

The purpose of this paper is to assess the comparative efficiency of Brazil's water and sanitation sector. We run a Stochastic Frontier Analysis (SFA) model for a panel of 127 providers covering more than 70 percent of the country's urban population in the period 2003–2010. We use a database...

In the whole world there are strong discussions on how to yield a more equitable access and a more efficient provision. One issue linked to efficiency is the achievement of scale economies in the industry, and the optimal dimension of water and sanitation providers. Changes in the industrial...

This paper presents a statistical analysis of the mergers and acquisitions (M&A) evaluated by the Argentinean competition authority, from 1999 to 2011. In particular, we analyze the evolution of the quantity of cases using different classifications and cross checks in accordance with the nature...

This paper uses survey-based data for the Argentinian province of C¨®rdoba to carry out an empirical test of the performance of the FLQ formula for regionalizing national inputoutput tables. Particular attention is paid to the problem of choosing a value for the unknown parameter ¦Ä in this...

A partial equilibrium model is used to quantify price differentials not explained by tax policy and efficiency cost in the international trade of dairy products between Argentina and some countries of European Union (EU). Prices of imports of EU from Argentina and European producer of the...

In this paper we use two computable general equilibrium models to evaluate gains of liberalization of trade in services for Argentina, Brazil and Uruguay. We employ two CGE models for the calculations. For the Argentine and Uruguayan cases, we apply a model built by the authors (see Chisari...
