Leitura do Dia - Is Arbitrage Tying the Price of Ethanol to that of Gasoline?
A discussão econômica sobre o uso de etanol como combustível tem sido marcado por uma mediocridade ímpar. Mas existem brilhantes excessões, como é o caso do artigo abaixo. Além disso este campo empirical industrial organization é atualmente uma das áreas mais interessantes de pesquisa em economia,

Abstract
As much of the world goes searching for alternative sources of energy to oil, Brazil.s three-decade experience in developing a successful substitute for gasoline merits attention. Brazil is the only sizable economy to date to have developed a ubiquitously distributed alternative to oil-based fuels in road transportation: ethanol from sugar cane. Perhaps unsurprisingly, the uptake of flexible-fuel (dual-fuel) vehicle technology has been tremendous. We provide a stylized model of the vertical sugar industry which incorporates arbitrage by producers, across domestic and export markets for ethanol and sugar, and arbitrage by consumers, across ethanol and gasoline at the pump. We show that the model stands up well to the empirical covariation in prices over 30 years. In particular, owing to the increasing penetration of flexible-fuel vehicles, consumer arbitrage is tying the retail price of ethanol to that of gasoline. Of relevance to the current .food-versus-fuel.debate, the outward shift of the ethanol demand curve, at price levels where traditional gasoline consumers arbitrage, may lead to higher sugar prices, thanks to substitution in demand (gasoline and ethanol) and in supply (sugar and ethanol).
