Abstract
This paper analyzes the effect of the earthquake occurred in March 2011 in Japan on nuclear power generation. More specifically as natural consequence, the hypothesis of moving towards generating sources different from nuclear are explored. Given the CO2 constraints and the discussion on biomass generation affecting the agricultural commodities prices, in a long-term perspective it is expected to observe a migration from thermal conventional electricity generation to renewable generation. Therefore, this study is provides some evidence on the effect of nuclear crisis caused by Fukushima on commodities prices of both energy and agricultural markets. We perform an event study analysis of abnormal returns considering short, medium and long run horizons.
