Information and sin goods: Experimental evidence on cigarettes
通过实验研究信息源（政府、私营公司、医生）对成年吸烟者选择电子烟和传统香烟的影响，发现信息源显著影响其戒烟和转向电子烟的意愿。
We test the importance of information source on consumer choice in the context of sin goods, specifically electronic and tobacco cigarettes, among adult smokers. We proxy choice with intentions to vape and quit smoking in the next 30 days. We experimentally vary the information source: government, private companies, physicians, and no source. Our findings suggest that information source matters in the context of cigarettes choice for adult smokers. Private companies appear to be an important information source for cigarettes among adult smokers.
