Getting to the top of mind: How reminders increase saving
We develop and test a simple model of limited attention in intertemporal choice.The model posits that individuals fully attend to consumption in all periods but fail to attend to some future lumpy expenditure opportunities. This asymmetry generates some predictionsthat overlap with models of present-bias. Our model also generates the unique predictions that reminders may increase saving, and that reminders will be more effective when they increase thesalience of a specific expenditure. We find support for these predictions in three field experiments that randomly assign reminders to new savings account holders.
