The impact of the anti-smoking campaign on the consumption of cigarettes is measured by fitting cigarette demand functions to pre-campaign dat, projecting "ahead" as if the campaign had not occurred, and then comparing these predictions with realized consumption. The analysis suggests that major "events" in the campaign (e.g., the Surgeon General's Report) caused immediate though transitory decreases of 4 to 5 per cent in annual per capita consumption. However, the cumulative effect of persistent publicity supported by other public policies, has been substantial: in the absence of the campaign, per capita consumption likely would have exceeded its actual 1975 value by 20 to 30 per cent. This is a conservative indication of the effectiveness of the campaign, for it ignores other potentially important and desirable behavior changes, such as the shift to low "tar" and nicotine cigarettes.
通过将香烟需求函数与控烟运动前的数据进行拟合,预测“如果没有开展该运动”的情况,然后将这些预测结果与实际消费量进行比较,来衡量控烟运动对香烟消费的影响。分析表明,该运动中的重大“事件”(如美国卫生局局长的报告)导致人均年消费量立即出现4%至5%的短暂下降。然而,其他公共政策支持下持续宣传的累积效应相当显著:如果没有这场运动,人均消费量可能会比1975年的实际值高出20%至30%。这是对该运动有效性的保守估计,因为它忽略了其他潜在的重要且可取的行为变化,比如转向低“焦油”和低尼古丁香烟。
