They released by ANP and through Box-Jenkins methodology. It was empirically verified that relative prices seem to follow a first-order autoregressive process, AR(1), with an average ratio equal marginal utility of ethanol (sugarcane) and gasoline (fossil fuel) liters, which is equal technical coefficient of 70 %. This result suggests that owners of dual-fuel ehicle technology in the face of consumer arbitrage became the natural official regulator of this market such as short as long term. / O comportamento dos preços relativos nacionais dos combustíveis líquidos (relação entre o preço do álcool e o da gasolina) foi analisado com base no painel desses preços mensais, em 27 unidades brasileiras, durante o período de julho de 2001 a fevereiro de 2008, disponibilizados pela ANP e por meio da Metodologia Box- Jenkins. Constatou-se empiricamente que os preços relativos parecem seguir um processo auto-regressivo da classe AR(1), com média igual à razão entre as utilidades marginais do litro do álcool e do litro da gasolina, ou seja, igual ao coeficiente técnico de 70%. Esse resultado sugere que os proprietários de carros bicombustíveis, mediante o poder de arbitragem, se tornaram o agente regulador natural deste mercado, tanto no curto quanto no longo prazo.
