Previous studies of cross-border cigarette purchases in the European Union (EU) relied on survey-reported data. Results of those studies might be affected by under-reporting of tax avoidance in those surveys. This study aims to shed light on the effects of cigarette price differences between EU Member States on cross-border cigarette purchases using a method that is free from potential reporting bias.
2004-2017 pooled time-series data and econometric modelling are used to examine cross-border shopping in the EU. Incentives for cross-border shopping are measured as a function of differences in cigarette prices between bordering countries, controlling for population density near borders. Separate incentive variables are calculated for EU internal versus EU external borders and for terrestrial versus maritime borders. Tax-paid cigarette sales are modelled as a function of cigarette price, per capita income, non-price measures and the incentive variables using fixed-effects models.
The estimated price elasticity of cigarette demand varies, depending on the model, from -0.47 to -0.35. The estimated income elasticity varies from 0.66 to 0.70. Between-country price differences are not significantly associated with purchases across maritime borders and across borders with non-EU neighbours. In an average EU Member State, reducing incentives from cross-border shopping down to zero would increase sales by 1.5% in an importing country and reduce sales by about 6% in an exporting country, ceteris paribus.
An upward convergence of cigarette prices across EU Member States would reduce cross-border cigarette purchasing and improve public health by contributing to decreases in cigarette consumption.
以往关于欧盟跨境香烟购买的研究依赖于调查数据报告。这些研究的结果可能受到调查中对避税行为的低报影响。本研究旨在通过一种不受潜在报告偏差影响的方法,阐明欧盟成员国之间香烟价格差异对跨境香烟购买的影响。
2004 年至 2017 年的 pooled 时间序列数据和计量经济学模型用于检验欧盟的跨境购物情况。边境国家之间的香烟价格差异被用作跨境购物动机的衡量指标,同时控制了边境附近的人口密度。针对欧盟内部和外部边境以及陆地和海上边境,分别计算了不同的激励变量。使用固定效应模型,将纳税香烟销售建模为香烟价格、人均收入、非价格措施和激励变量的函数。
根据模型的不同,香烟需求的价格弹性估计值从-0.47 到-0.35 不等。收入弹性的估计值从 0.66 到 0.70 不等。国家间价格差异与海上边境和非欧盟邻国边境的跨境购买没有显著关联。在一个平均的欧盟成员国中,将跨境购物的激励因素减少到零,将使进口国的销售额增加 1.5%,出口国的销售额减少约 6%,其他条件不变。
欧盟成员国之间香烟价格的趋同上升将减少跨境香烟购买,通过降低香烟消费,有助于改善公共健康。
