    Evidencia empírica en alta frecuencia de la prima de riesgo forward para los mercados de energía eléctrica en Colombia
    (Universidad EAFIT, 2009) Salazar Marín, Gloria Stella; Pantoja Robayo, Javier Orlando
    Supported on empirical analysis and using a high-frequency data set of hourly spot and forward prices from wholesale power market in Colombia, this paper finds that there are significant riskpremia in electricity forward prices, showing how their properties and behavior are also explained by the differences among market segments and regulation. These premia vary depending on the market segment, showing that median risk premium is positive for most of the hours for two segments and negative for another. On the other hand, it presents evidence about the structural changes in the wholesale market, due to that this market is in a consolidation process and so, it is highly sensitive to the regulation changes, which generated special conditions that impacted the market’s behavior and the agent’s risk tolerance.
