This study aimed to analyze the existence of asymmetric transmission of prices in the Brazilian gasoline market following a regional approach, using a disaggregated data set for the period between May 2004 and February 2011. The main result finds evidence of symmetric price transmission in retail gasoline market due to price shocks arising from the distributors. It is important to highlight that the disaggregation of the data allowed the study to show that the asymmetry is not a national problem, but specific to each city and different for each of the regions in Brazil.
