Getting to the Top of Mind: How Reminders Increase SavingDean S. KarlanYale University Margaret McConnellHarvard University Sendhil MullainathanHarvard University - Department of Economics; National Bureau of Economic Research (NBER) Jonathan ZinmanDartmouth College; Innovations for Poverty Action; Jameel Poverty Action Lab; National Bureau of Economic Research (NBER) July 1, 2010 Yale University Economic Growth Center Discussion Paper No. 988 Yale Economics Department Working Paper No. 82 Abstract: 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 predictions that 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 the salience of a specific expenditure. We find support for these predictions in three field experiments that randomly assign reminders to new savings account holders.
