We use the wavelet coherence methodology to investigate relations between prices of ethanol and its feedstocks. Our … between prices of ethanol and corn (in USA) or sugar (in Brazil) is positive, strong and stable in time. Importantly, we show … that the prices of feedstock lead the prices of ethanol and not the other way around. The price lead of feedstock is …
