This study analyzes the elasticities of demand and income from electricity for domestic and industrial use, for Colombia (2000-2011), by estimating demand equations by OLS. The impacts on macroeconomic variables, which generate changes in the price of electricity, are also estimated by using a...

Electricity prices have seen a consistent upward trend since the implementation of Mexico's electricity market reform (EMR). This has been interpreted by some as a failure of the EMR. In this paper we study the determinants of such price increases. We calculate the generation cost curve of the...

This paper is about a model of Bertrand competition in a homogeneous-good market with free entry of identical firms and variable returns to scale. If the optimum number of active firms in the market is two or more, and the number of active firms is equal to that optimum number, then Bertrand...

Taking as a reference a model in which there are a public firm, a national private firm and a foreign private one, it is analyzed both mergers sustainability and their relative effects on welfare. It is proved that the merger between the public firm and either the national or the international...

The aim of this paper is to complement the existing literature on horizontal mergers, by setting a Cournot mixed oligopoly model. Specifically, the merger paradox is qualified by proving that a merger could be profitable for the merging firms even if it does not include most market firms....

We analyze the behavior of electricity generation groups that make investment and production decisions in a liberalized market scenario by introducing long-term contracts, in a context where there is a high level of market concentration. In this way, a dynamic deterministic model of imperfect...

Taking as a reference a simple oligopoly model with differentiated products, in which there are three firms, the purpose of this paper is to complement the existing literature on mergers by proving that the traditional merger paradox can be avoided by assuming that, after the merger, the merging...

The objective of this contribution is to evaluate the weekly price dynamics of the biscuit sector in the framework of an economy with moderate inflation, such as Argentina. Using weekly frequency data, five versions of the function that relate cookie price weekly variations with their possible...

This study presents the competition beyond a single product market where a multi-product firm competes with monoproduct rivals through the use of different bundling strategies that impact the firms' incentives to make quality improvements in different ways. The pure bundling strategy can make...

El objetivo del presente trabajo es validar la existencia de poder de mercado ejercido por una firma integrada verticalmente en el mercado de procesamiento de operaciones realizadas mediante tarjetas de pago. La metodología usada se basa en el análisis de la variación de ese indicador como...
