To investigate how affordable cigarettes are in developed and developing countries, and to calculate by how much the affordability of cigarettes has changed between 1990 and 2001; and secondly, to investigate the relation between cigarette affordability and consumption.
Affordability was defined as the cost of cigarettes relative to per capita income. Trends in cigarette affordability, and affordability elasticities of demand, were estimated using regression techniques.
Seventy countries were investigated, of which 28 are categorised as high income developed countries, while 42 are categorised as developing countries. Cigarette prices were obtained for the main city/cities in the countries.
Despite the fact that cigarettes are more expensive in developed countries, the high levels of income make cigarettes more affordable in these countries vis-a-vis developing countries. Of the 28 developed countries, cigarettes became more affordable in 11 and less affordable in 17 countries during the 1990s. Of the 42 developing countries, cigarettes became more affordable in 24 and less affordable in 18 countries. Based on a cross sectional analysis, a 1% increase in the relative income price (the inverse of cigarette affordability) is expected to decrease cigarette consumption by between 0.49-0.57%.
Cigarette affordability, more than just the price, determines cigarette consumption. While cigarettes have become more affordable in many developing countries, some developing countries (for example, South Africa, Poland, and Thailand) have implemented strong and effective tobacco control policies, and have been able to decrease cigarette consumption as a result.
调查在发达国家和发展中国家香烟的可负担性如何,并计算1990年至2001年间香烟可负担性的变化幅度;其次,调查香烟可负担性与消费之间的关系。
可负担性被定义为香烟成本相对于人均收入的比例。使用回归技术估计香烟可负担性的趋势以及需求的可负担性弹性。
对70个国家进行了调查,其中28个被归类为高收入发达国家,42个被归类为发展中国家。获取了这些国家主要城市的香烟价格。
尽管在发达国家香烟价格更高,但高收入水平使得这些国家的香烟相对于发展中国家更具可负担性。在28个发达国家中,20世纪90年代有11个国家的香烟变得更具可负担性,17个国家的香烟可负担性降低。在42个发展中国家中,24个国家的香烟变得更具可负担性,18个国家的香烟可负担性降低。基于横断面分析,相对收入价格(香烟可负担性的倒数)每增加1%,预计香烟消费量将减少0.49 - 0.57%。
香烟的可负担性而非仅仅价格决定了香烟消费。虽然在许多发展中国家香烟变得更具可负担性,但一些发展中国家(例如南非、波兰和泰国)实施了强有力且有效的烟草控制政策,并因此能够减少香烟消费。
