We analyze the behavior of spot prices in the Colombian wholesale power market, using a series of models derived from industrial organization theory.  We first create a Cournot-based model that simulates the strategic behavior of the market-leader power generators, which we use to estimate two industrial organization variables, the Index of Residual Demand and the Herfindahl-Hirschman Index (HHI).  We use these variables to create VAR models that estimate spot prices and power market impulse-response relationships.  The results from these models show that hydroelectric generators can use their water storage capability strategically to affect off-peak prices primarily, while the thermal generators can manage their capacity strategically to affect on-peak prices.  In addition, shocks to the Index of Residual Capacity and to the HHI cause spot price fluctuations, which can be interpreted as the generators´ strategic response to these shocks.

Este artículo trata de mostrar la relación positiva que existe entre la inversión en infraestructura de transporte y el crecimiento económico. No obstante lo complejo del tema. A partir de la revisión bibliografía existente inicialmente se establece dicha relación y después presenta los métodos que se han utilizado para modelar esta relación.
