This study evaluated the direct effect of the tobacco price support program on domestic cigarette consumption.
We developed an economic model of demand and supply of US tobacco to estimate how much the price support program increases the price of tobacco. We calculated the resultant increase in cigarette prices from the change in the tobacco price and the quantity of domestic tobacco contained in US cigarettes. We then assessed the reduction in cigarette consumption attributable to the price support program by applying the estimated increase in the cigarette price to assumed price elasticities of demand for cigarettes.
We estimated that the tobacco price support program increased the price of tobacco leaf by $0.36 per pound. This higher tobacco price translates to a $0.01 increase in the price of a pack of cigarettes and an estimated 0.21% reduction in cigarette consumption.
Because the tobacco price support program increases the price of cigarettes minimally, its potential health benefit is likely to be small. The adverse political effect of the tobacco program might substantially outweigh the potential direct benefit of the program on cigarette consumption.
本研究评估了烟草价格支持计划对国内卷烟消费的直接影响。
我们建立了美国烟草供需经济模型,以估计价格支持计划使烟草价格提高了多少。我们根据烟草价格变化和美国卷烟中所含国内烟草数量计算出卷烟价格的相应上涨。然后,通过将估计的卷烟价格上涨应用于假定的卷烟需求价格弹性,评估价格支持计划导致的卷烟消费减少情况。
我们估计,烟草价格支持计划使烟叶价格每磅提高了0.36美元。这种较高的烟草价格转化为每包卷烟价格上涨0.01美元,估计卷烟消费减少0.21%。
由于烟草价格支持计划使卷烟价格的涨幅极小,其潜在的健康益处可能很小。烟草计划的负面政治影响可能大大超过该计划对卷烟消费的潜在直接益处。
