In June, 2013, Louisville, Kentucky, announced plans to provide restaurant health inspection scores—already available on the city’s website—for publication on Yelp.com. I find that this increased salience caused substantial hygiene improvements among independent Louisville restaurants across three different counterfactual models. Among independent Louisville restaurants, estimates suggest the partnership caused anywhere from a 9‐14% relative decrease in inspection score point deductions, with the effect being entirely evident in restaurants’ first inspections following the partnership’s announcement. Relative to the rest of Kentucky, I find that the partnership significantly reduced rates of severe food poisoning in Louisville.

信息显着性对产品质量的影响：路易斯维尔餐厅卫生和Yelp.com *

2013年6月，肯塔基州路易斯维尔宣布计划提供餐馆健康检查评分（已在纽约市的网站上提供），以在Yelp.com上发布。我发现，这种显着性的提高在三种不同的反事实模型中，在独立的路易斯维尔餐厅之间大大改善了卫生状况。据估计，在独立的路易斯维尔餐厅中，这种伙伴关系导致检查分数扣除额相对减少了9-14％，这种影响在伙伴关系宣布后对餐馆的首次检查中是完全明显的。相对于肯塔基州的其他地区，我发现这种合作关系大大降低了路易斯维尔的严重食物中毒发生率。
