The Behavioralist as Nutritionist: Leveraging Behavioral Economics To Improve Child Food Choice and Consumption
通过一项超过1500名儿童的田野实验，发现小额激励能大幅提升健康零食选择率（从17%升至约75%），且效果在干预后持续，而单纯教育信息效果有限。
We leverage behavioral economics to explore new approaches to tackling child food choice and consumption. Using a field experiment with >1500 children, we report several key insights. We find that incentives have large influences: in the control, 17% of children prefer the healthy snack, whereas introduction of small incentives increases take-up of the healthy snack to ∼75%. There is some evidence that the effects continue post-treatment, consistent with a model of habit formation. We find little evidence that the framing of incentives (loss vs. gain) matters. Educational messaging alone has little effect, but we observe a combined effect of messaging and incentives: together they provide an important influence on food choice.
