This paper analyzes the relationship between gasoline and ethanol markets. Previous researches emphasize on substitution effect between gasoline and ethanol. However, in Brazil gasoline and ethanol are substitutes and complementary goods. We investigate the substitution and complementarity effects between fuels by using Structural Vector Autoregressions Vector (SVAR). As a result, in the short run gasoline price shock effect in ethanol demand is greater than ethanol price shock. In the long run, however, consumers make the consumption of ethanol grow. Furthermore, the introduction of flex fuel technology in Brazil did not produce any impact on ethanol price and demand. The crisis has affected positively the biofuel price nevertheless. As an implication, due to gasoline price shock the sucroalcohol sector must guarantee the ethanol domestic supply in the long run.
