Goal Setting and Saving in the FinTech Era
利用金融科技App的数据，研究发现设定储蓄目标能提高用户的储蓄率，且不减少App外的储蓄，尤其对低储蓄倾向者效果显著。
ABSTRACT We study the effectiveness of saving goals in increasing individuals' savings using data from a Fintech app. Using a difference‐in‐differences identification strategy that randomly assigns users into a group of beta testers who can set goals and a group of users who cannot, we find that setting goals increases individuals' savings rate. The increased savings within the app do not reduce savings outside the app. Moreover, goal setting helps those individuals previously identified as having the lowest propensity to save. Matching App user survey responses to their behavior highlights the relative merits of monitoring and concreteness channels in explaining our findings.
