GASOLINE PRICES, GOVERNMENT SUPPORT, AND THE DEMAND FOR HYBRID VEHICLES IN THE UNITED STATES*
研究了汽油价格和联邦所得税抵免如何影响美国混合动力汽车需求，发现2006年若油价维持1999年水平，销量将降低37%，而税收抵免贡献了20%的销量增长。
We analyze the determinants of hybrid vehicle demand, focusing on gasoline prices and income tax incentives. We find that hybrid vehicle sales in 2006 would have been 37% lower had gasoline prices stayed at the 1999 levels, and the effect of the federal income tax credit program is estimated at 20% in 2006. Under the program, the cost of reducing gasoline consumption was $75 per barrel in government revenue and that of CO2 emission reduction was $177 per ton. We show that the cost effectiveness of federal tax programs can be improved by a flat rebate scheme.
