Creating a Cell Phone-Based Defined Contribution Account

Researchers Michael Callen, Joshua Blumenstock and Tarek Ghani build on an earlier CFSP project to implement a randomized field experiment in Afghanistan to test the effects of mobile phone-based defined contribution accounts ("M-Pasandaaz") on savings outcomes in a private firm with approximately 1,200 employees.  This study explores the extent to which a mobile phone-based defined contribution account can improve the financial capabilities and welfare outcomes for these employees.

Research Questions: 
  • Can a salary-linked savings product create an enduring increase in savings, even in a highly uncertain environment?
  • What explanation for why Afghans have low levels of formal savings is most accurate in the data: present-biased preferences; aversion to complex decisions; distrust of formal banks; or liquidity constraints?
  • Which constraints can a defined contribution product solve?
  • How does an individual's default enrollment status impact rates of participation and accumulated savings?
  • How can defined contribution accounts be best designed to encourage contributions?
