Policy makers increasingly use choice defaults to promote "good" causes by influencing socially relevant decisions in desirable ways, e.g., to increase pro-environmental choices or pro-social behavior in general. Such default nudges are remarkably successful when judged by their effects on the targeted behaviors in isolation. However, there is scant knowledge about possible spillover effects of pro-social behavior that was induced by defaults on subsequent related choices. Behavioral spillover effects could eliminate or even reverse the initially positive effects of choice defaults, and it is thus important to study their significance. We report results from a laboratory experiment exploring the subsequent behavioral consequences of pro-social choice defaults. Our results are promising: Pro-social behavior induced by choice defaults does not result in adverse spillover effects on later, subsequent behavior. This finding holds for both weak and strong choice defaults. C91, D01, D04.
政策制定者越来越多地通过以理想的方式影响与社会相关的决策来使用选择默认设置，以促进“良好”事业，例如，总体上增加亲环境选择或亲社会行为。仅从它们对目标行为的影响来判断，这种默认推动非常成功。然而，对于由默认设置引发的亲社会行为对后续相关选择可能产生的溢出效应，人们知之甚少。行为溢出效应可能会消除甚至逆转选择默认设置最初的积极影响，因此研究它们的重要性很有必要。我们报告了一项实验室实验的结果，该实验探讨了亲社会选择默认设置的后续行为后果。我们的结果很有前景：由选择默认设置引发的亲社会行为不会对后来的后续行为产生不利的溢出效应。这一发现适用于弱选择默认设置和强选择默认设置。C91、D01、D04。
