网络中行为干预的长期道德效应
Long-term morality effects of behavioral interventions in networks
摘要
In this paper, we develop a dynamic model of moral preferences in repeated public goods games on networks. We incorporate informational nudges and derive conditions for convergence of behavior and optimal targeting of policies. Importantly, the long-term impact of moral nudges on preferences and behavior depends on how preferences evolve. When preferences include a component of persistent intrinsic morality, the effect of a moral nudge dissipates over time. Conversely, if social preferences continuously evolve, influenced by recent periods and present experiences, the potential for long-lasting effects of behavioral interventions becomes more promising. We also discuss heterogeneous adaptation, which improves the model’s predictive power for laboratory public-goods experiments. With the framework constructed in this paper, outcomes in experimental, field and natural experiments can be evaluated to further understand what drives individual decision making.
中文摘要
本文构建了一个网络重复公共品博弈中的道德偏好动态模型。我们引入信息助推，推导出行为收敛与政策最优靶向的条件。重要的是，道德助推对偏好与行为的长期影响取决于偏好的演化方式。当偏好包含持久内在道德成分时，道德助推的效果会随时间消散。相反，若社会偏好持续演化，受近期阶段与当前经验影响，行为干预产生持久效应的可能性将更为乐观。我们还讨论了异质性适应问题，这提升了模型对实验室公共品实验的预测能力。借助本文构建的分析框架，可评估实验、实地实验与自然实验的结果，从而进一步理解个体决策的驱动因素。
