We use an innovative method to analyze the spatio-temporal evolution of the ethanol/gasoline price ratio to end consumers in Brazil. This model allows estimating the distribution of prices throughout the country using a continuous space model estimated by Bayesian methods. We use data from the National Petroleum, Natural Gas and Biofuels Agency's price survey system, a weekly sample of 10% of fuel suppliers in Brazil, to estimate continuous projections of the price ratio for the entire country for the 2007–2014 period. We use this model to build an indicator of ethanol advantage in the country and show how this advantage has declined since 2009.
