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,...
