Price and income elasticities of demand for passenger transport fuels in Spain. Implications for public policies

摘要: Abstract The significant increase in passenger transport activity (cars) experienced by Spain and its associated energy consumption have several negative aspects, including a greater dependence on foreign sources higher GHG emissions. Therefore, reducing the level of would bring important socioeconomic environmental benefits. aim this paper, which focuses transport, is fourfold: (1) to provide diagnostic Spanish system related problems; (2) develop model calculate price income elasticities demand for fuel; (3) apply sector; (4) infer policy recommendations derived from results model. It claimed that, view those low high if reduction scale deemed socially desirable, combination instruments necessary. Fuel taxes play an role within combination. Apart their long-term effects, elasticity fuel allow collection amount revenues, could eventually be earmarked encourage reductions private modal shifts with other instruments.
