Judgment and Decision Making (Jan 2013)
Savings, subgoals, and reference points
Abstract
Decision makers often save money for a specific goal by forgoing discretionary consumption and instead putting the money toward the savings goal. We hypothesized that reference points can be exploited to enhance this type of saving. In two hypothetical scenario studies, subjects made judgments of their likelihood to forgo a small expenditure in order to put the money toward the savings goal. In Experiment 1, judgments were higher if the savings goal was presented as composed of weekly subgoals (e.g., save $60 per week to buy a $180 iPod). Experiment 2 replicated this finding and demonstrated that the subgoal manipulation increased judgments of likelihood to save money only when the money saved from the foregone consumption would allow the decision maker to meet the weekly subgoal exactly (not under or overshoot it). These results suggest a reference point mechanism and point to ways that behavioral decision research can be harnessed to improve economic behaviors.
