Impacto sobre el bienestar social atribuido al fenómeno El Niño (ENOS) y al proceso de cambio climático. Un análisis sobre el mercado de energía colombiano

Abstract

This article develops and makes use of a simulation model of the Colombian electricity market, based on the theoretical model of Nash-Cournot, on which the change in consumer welfare was estimated, due to the occurrence of El Niño (ENSO) important events, such as those in 1997-1998, as well as the possible occurrence of events of greater intensity, a result of the climate change. The estimates obtained indicates that the event of the year 1997-1998, caused losses of consumer welfare of $ 1, 2 billion pesos (0.9% of 1998-GDP). Similarly, more intense events may cause losses on the welfare of between 0.36% and 0.55% of GDP.
