The overall price elasticity of cigarette consumption in Bangladesh has been studied extensively. The estimates of price elasticity by price tiers are not available in the existing literature.
Using cohort data of nearly 6000 individuals from the International Tobacco Control Bangladesh survey, this study estimated the own-price and cross-price elasticity and income elasticity of cigarette demand by price tiers in Bangladesh. The elasticity was estimated in three stages of consumer decisions: whether to smoke, which brand to smoke and finally, how many cigarettes to smoke per day. The decision to smoke cigarettes and the choice of cigarette brands were modelled using instrumental variable probability regression. The cigarette consumption per day was modelled using seemingly unrelated regression.
The price elasticity of cigarette smoking prevalence with respect to the price of low-price cigarettes is -0.0487. The total elasticity for low-price cigarette consumption with respect to its own price is -0.1678. The own-price elasticity of smoking intensity of high-priced brands is -0.2512. The cross-price elasticity of low-price cigarette consumption with respect to high-price brand prices is 0.2643. The income elasticity of smoking prevalence overall is 0.0564. The income elasticity of daily consumption of low-price cigarettes is -0.1934 and for high-price cigarettes, it is 1.4044. The total income elasticity is 1.4608 for high-price cigarettes.
A cigarette tax policy that raises the prices of both low-price and high-price brands-but increases prices in the low-price tier at a faster rate than in the high-price tier and increases prices of all brands at a pace faster than income growth-can effectively reduce cigarette consumption in Bangladesh.

已广泛研究孟加拉国香烟消费的总体价格弹性。现有文献中没有按价格层次划分的价格弹性估计值。
本研究使用来自孟加拉国国际烟草控制调查的近 6000 名个体的队列数据,按价格层次估算了孟加拉国香烟需求的自价格和交叉价格弹性以及收入弹性。在消费者决策的三个阶段估算了弹性:是否吸烟、吸哪种品牌香烟以及每天吸多少支香烟。使用工具变量概率回归模型来模拟吸烟决策和香烟品牌选择。使用似不相关回归模型来模拟每天的香烟消费量。
低价香烟价格对香烟吸烟流行率的价格弹性为-0.0487。低价香烟消费的总弹性对其自身价格为-0.1678。高价品牌吸烟强度的自价格弹性为-0.2512。低价香烟消费对高价品牌价格的交叉价格弹性为 0.2643。总体吸烟流行率的收入弹性为 0.0564。低价香烟每日消费的收入弹性为-0.1934,高价香烟的收入弹性为 1.4044。高价香烟的总收入弹性为 1.4608。
一项既能提高低价和高价品牌价格,但提高低价品牌价格的速度快于高价品牌,且提高所有品牌价格的速度快于收入增长的香烟税收政策,可以有效减少孟加拉国的香烟消费。
