Promoting Healthy Choices: Information versus Convenience
在一家快餐三明治连锁店的实地实验中，研究了提供卡路里信息和让健康选择更便利对减少卡路里摄入的影响，发现信息有效，但便利性措施效果有限。
Success in slowing obesity trends would benefit from policies aimed at reducing calorie consumption. In a field experiment at a fast-food sandwich chain, we address the effects of providing calorie information, mimicking recent legislation, and test an alternative approach that makes ordering healthier slightly more convenient. We find that calorie information reduces calorie intake. Providing a daily calorie target does as well, but only for non-overweight individuals. Making healthy choices convenient reduces intake when the intervention is strong. However, a milder implementation reduces sandwich calories, but does not reduce total calories due to compensatory effects on side orders and drinks.
