The purpose of this paper is to evaluate the sensitivity of fuel consumers regarding price and income, taking recent changes in the Brazilian fuel market into account. In this market, new market rules, energy policy towards fuel diversification and introduction of flex-fuel engines have determined fuel competition among gasoline, ethanol and compressed natural gas. Using a dynamic panel data model, demand equations for these three fuels are econometrically estimated to obtain consumer adjustment coefficients, price, cross-price and income elasticities in the short and long-run. In addition, the effect of the introduction of flex-fuel engines in the market and the rationality of consumers towards efficiency constraints of the engines were tested. Apart from considerable competition, results show that the dynamics of the Brazilian fuel market revolves around ethanol instead of gasoline. While demands for gasoline and natural gas are inelastic to price, demand for ethanol is elastic in Brazil. Furthermore, after the introduction of the flex-fuel technology the sensitivity of consumers to fuel prices changed, and ethanol consumers take efficiency constrains into account when ethanol prices reach the threshold of 70% of gasoline prices.
⺠Fuel demand in Brazil is evaluated, considering the changes in the fuel market. ⺠A dynamic panel data model is used to fit demand equations for fuels. ⺠Adjustment coefficients, price, cross-price and income elasticities are estimated. ⺠The impact of flex-fuel technology on the consumer behavior is tested. ⺠The results showed that the dynamic of the fuel market revolves around ethanol. ⺠The flex-fuel technology increased the competition among fuels.
