(Ineffective) Messages to Encourage Recycling: Evidence from a Randomized Evaluation in Peru
研究在秘鲁随机测试了九种基于最佳实践和行为理论的回收宣传信息，发现均未显著改变回收行为，但提供回收桶显著提高了参与家庭的回收率。
Abstract: There is growing interest in using messaging to drive pro-social behaviors, which contribute to investment in public goods. We worked with a leading NGO in Peru to randomize nine different pro-recycling messages that were crafted based on best practice, prior evidence, and theories of behavioral change. Different variants emphasized information on environmental or social benefits, social comparisons, social sanctions, authority, and/or reminders. None of the messages had significant effects on recycling behavior. However, reducing the cost of ongoing participation—by providing a recycling bin—significantly increased recycling among enrolled households.
