Saving for Multiple Financial Needs: Evidence from Lockboxes and Mobile Money in Malawi
在马拉维对761名微型企业家进行实验，发现提供多个锁箱储蓄账户使储蓄增加40%，但第二个移动货币账户因技术问题效果不佳；两种账户均影响农业决策和客户信贷等下游结果。
Abstract We test whether the provision of multiple labeled savings accounts affects savings and downstream outcomes in an experiment with 761 microentrepreneurs in urban Malawi. Treatment respondents received one or multiple savings accounts, in the form of lockboxes or mobile money. We find that while providing additional boxes increased savings by 40%, technical issues marred the efficacy of a second mobile money account. Data from novel high-frequency surveys suggest that both types of accounts had impacts on downstream outcomes, including farming decisions and credit extended to customers. We do not detect differential downstream effects by the number or modality of accounts.
