Tobacco use is a significant risk factor for the leading causes of death worldwide, including cancer, heart disease and stroke. Most of these deaths occur in low- and middle-income countries, where tobacco-related deaths are also rising rapidly. Taxation is one of the most effective tobacco control measures, yet evidence on the distributional impact of tobacco taxation in low- and middle-income countries remains scant. This paper considers the financial and health effects, by socio-economic class, of increasing tobacco taxes in Lebanon, a middle-income country. An Almost Ideal Demand System is used to estimate price elasticities of demand for tobacco products. Extended cost-effectiveness analysis (ECEA) methods are applied to quantify, across quintiles of socio-economic status, the health benefits gained, the additional tax revenues raised, and the net financial consequences for households from a 50% increase in the price of tobacco through excise taxes. We find that demand for tobacco is price inelastic with elasticities ranging from -0.32 for the poorest quintile to -0.22 for the richest quintile. The increase in tobacco tax is estimated to result in 65,000 (95% CI: 37,000-93,000) premature deaths averted, 25% of them in the poorest quintile, $300M ($256-340M) of additional tax revenues, 12% borne by the poorest quintile, $23M ($13-33M) of out-of-pocket spending on healthcare averted, 36% of which accrue to the poorest quintile, 9% to the richest. These savings would be associated with 23,000 (13,000-33,000) poverty cases averted (63% in the poorest quintile). Increasing tobacco taxes would lead to large financial and health benefits, and would be pro-poor in health gains, savings on healthcare, and poverty reduction.
吸烟是全球主要死因的一个重要风险因素,这些死因包括癌症、心脏病和中风。其中大多数死亡发生在低收入和中等收入国家,在这些国家,与烟草相关的死亡人数也在迅速上升。税收是最有效的烟草控制措施之一,但关于烟草税收在低收入和中等收入国家的分配影响的证据仍然很少。本文探讨了在中等收入国家黎巴嫩提高烟草税对不同社会经济阶层的财政和健康影响。采用几乎理想需求系统来估计烟草产品的需求价格弹性。应用扩展成本效益分析(ECEA)方法,按社会经济地位五分位数量化通过消费税使烟草价格提高50%所带来的健康益处、额外增加的税收收入以及家庭的净财务后果。我们发现,烟草需求缺乏价格弹性,弹性范围从最贫困五分位数的-0.32到最富裕五分位数的-0.22。估计提高烟草税将避免65000例(95%置信区间:37000-93000)过早死亡,其中25%发生在最贫困五分位数人群中,带来3亿美元(2.56-3.40亿美元)的额外税收收入,其中12%由最贫困五分位数人群承担,避免2300万美元(1300-3300万美元)的医疗保健自付费用,其中36%归于最贫困五分位数人群,9%归于最富裕人群。这些节省将与避免23000例(13000-33000例)贫困情况相关(63%发生在最贫困五分位数人群中)。提高烟草税将带来巨大的财政和健康效益,并且在健康收益、医疗保健节省和减贫方面有利于穷人。
