主题：Nudge Me: Preferences over Default-Setting Rules

讲座简介：

We study how choices are influenced by the procedure used to select the default option. In a within-subject lottery choice experiment, we compare four different default-setting rules: Random defaults, Custom defaults based on an individual’s own past choices, Social defaults based on others’ choices, and Expert-set defaults. Using tests that control for default quality and heterogeneous preferences, we find that default bias is higher for non-random default-setting rules. We find a similar effect with a designated option that is not pre-selected, demonstrating that default bias is primarily driven by the message contained in default-setting rules. We then elicit subjects’ preferences over default-setting rules and find that the majority (~80%) prefer to have non-random defaults. These results support the endorsement effect as a driver of default bias, and suggests that communicating the way the default option was selected can strengthen default bias.
