Age limit restriction for risky products is widely implemented as an instrument to improve public health. To study reasons for vendor (non-)compliance this 2 (underage vs. adult consumer) × 2 (low vs. high profit) field experimental research was conducted. Trained mystery shoppers conducted 218 alcohol purchase attempts. ID checks and compliance were significantly higher when financial profit was low (74% ID checks; 67% compliance) compared with the high-profit conditions (26%; 18%). There were no significant differences between the adult and underage consumer conditions. The motivation to comply appears to be the crucial factor, and enforcement needs to be intensified.
年龄限制限制对于危险产品的广泛实施是作为改善公共卫生的一种手段。为了研究供应商（不合规）遵守的原因，进行了这项 2（未成年消费者与成年消费者）×2（低利润与高利润）的现场实验研究。经过培训的神秘顾客进行了 218 次酒精购买尝试。当财务利润较低时（74%的身份证检查；67%的合规），与高利润条件相比（26%；18%），身份证检查和合规的比例显著更高。在成年消费者和未成年消费者的条件之间没有显著差异。遵守的动机似乎是关键因素，需要加强执法力度。
