Un modelo Casi Ideal de Demanda de Combustibles para la Industria de Transporte

This article presents an Almost Ideal Demand System (AIDS) for different types of fuels in Colombia, focusing specifically on the transport industry. Estimates of price, expenditure and cross elasticities are computed using a Seemingly Unrelated Regressions (SUR) model and based on 10 years observations (2003-2012). Results show that diesel and regular gas behave as inelastic goods while natural gas is more elastic. Also, diesel fuels and natural gas seem to behave as substitutes while there’s a complementary relation among the others (regular gas-Diesel; regular fuels-Natural Gas). Regarding the expenditures elasticities, this paper concludes that regular gas and diesel behave as normal goods while natural gas seems be an inferior type of fuel for the transport sector.
