Wintertime for Deceptive Advertising?
研究利用滑雪场自报降雪量与政府数据的差异，揭示虚假广告的普遍性、机制和动态，发现周末夸大更严重，且对拥有专家地形和不提供退款保证的度假村更显著。
Casual empiricism suggests that deceptive advertising about product quality is prevalent, and several classes of theories explore its causes and consequences. We provide unusually sharp empirical evidence on its extent, mechanics, and dynamics. Ski resorts self-report substantially more natural snowfall than comparable government sources. The difference is more pronounced on weekends‚ despite third-party evidence that snowfall is uniform throughout the week— as one would expect given plausibly greater returns to exaggeration on weekends. Exaggeration is greater for resorts that plausibly reap greater benefits from it: those with expert terrain and those not offering money back guarantees.
