The study attempts to estimate the demand for cigarettes in Tanzania and presents simulation results on the effect of the cigarette excise tax on smoking participation, government revenue, and related topics. After briefly summarizing the magnitude and spread of cigarette consumption in the country, the paper reviews some empirical estimates from African and other countries. The 2008 Tanzanian household budget survey was used to estimate the demand for cigarettes in Tanzania. The descriptive statistics suggest that the smoking prevalence for Tanzania is 15.35 percent with low variability across expenditure (income) groups. Smoking intensity and per capita consumption were estimated at 7.08 cigarettes and 1.33 cigarettes, respectively, a relatively low value. A two-part demand equation model was used to estimate various elasticities. For the overall equation, the price elasticities of smoking participation, smoking intensity, and total elasticity were estimated at -0.879, -0.853, and -1.732, respectively. Compared to similar results in other developing countries, the estimates appear quite high. When estimated by expenditure (income) groups, the magnitude of the elasticity appears higher among high expenditure groups than among low expenditure groups. Two simulation exercises were undertaken. First, the effect of different excise rates on smoking participation rate, cigarette consumption, tax revenue, and related responses was estimated and highlighted. Second, the same exercise was undertaken to determine the effect of a given increase in the cigarette excise tax on various expenditure groups. The overall results suggest that an increase in the excise tax on cigarettes in Tanzania would reduce cigarette consumption and increase government tax revenue.
该研究试图估算坦桑尼亚的香烟需求量,并给出关于香烟消费税对吸烟参与率、政府税收及相关主题影响的模拟结果。在简要概述该国香烟消费的规模和分布后,本文回顾了来自非洲及其他国家的一些实证估计。2008年坦桑尼亚家庭预算调查被用于估算该国的香烟需求量。描述性统计表明,坦桑尼亚的吸烟率为15.35%,各支出(收入)群体间的差异较小。吸烟强度和人均消费量分别估计为7.08支和1.33支,相对较低。采用两部分需求方程模型来估算各种弹性。对于总体方程,吸烟参与率、吸烟强度和总弹性的价格弹性分别估计为-0.879、-0.853和-1.732。与其他发展中国家的类似结果相比,这些估计值显得相当高。按支出(收入)群体进行估计时,高支出群体的弹性幅度似乎高于低支出群体。进行了两项模拟分析。首先,估计并强调了不同消费税税率对吸烟参与率、香烟消费、税收收入及相关反应的影响。其次,进行同样的分析以确定香烟消费税给定增幅对各支出群体的影响。总体结果表明,坦桑尼亚提高香烟消费税将减少香烟消费并增加政府税收收入。
