In this paper, we study the relationship between reconciliations in the Colombian electricity market and the bid prices by firms on the spot market. In this work,we propose a model of behavior of the firm to elaborate theoretical predictions about the relationship between the reconciliations and...

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...

One of the most important economic strategic sectors in any economy is the electricity market. Its main feature is its oligopolistic character favoured by the returns to scale which act as an entry barrier. As a result, the energy generators can use their power market in order to increase their...

La red productiva representa un mecanismo económico clave para comprender cómo los choques microeconómicos se propagan en el sistema económico. En esta línea se han desarrollo diversos trabajos teóricos bajo el supuesto de libre competencia, sin considerar el poder de mercado ni la posible...

We analyze the credit channel effects on new residential property prices in Medellín, Colombia, using a simultaneous equations model. Our empirical results show that the main determinants of new residential properties prices are mortgage interest rates and the availability of government...

We study cartel stability in a differentiated price-setting duopoly with returns to scale. We show that a cartel may be equally stable in the presence of lower differentiation, provided that the decreasing returns parameter is high. In addition we demonstrate that for a given factor of discount,...

In this article we develop a microeconomic framework to study the relationships among privatization, competition for deposits and performance in banking. Particularly, we analyze banking privatization when competitive strategies of the Cournot and Stackelberg types are allowed. Our findings show...

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...

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...

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...
