Cass R. Sunstein, The Distributional Effects of Nudges, 6 Nature Hum. Behav. 9 (2021).
Abstract: Nudges are tools to achieve behavioural change. To evaluate nudges, it is essential to consider not only their overall welfare effects but also their distributional effects. Some nudges will not help, and might hurt, identifiable groups. More targeted, personalized nudging may be needed to maximize social welfare and promote distributive justice.
