Interventions
Intervention(s)
The total sample of 783 remittance receivers were randomly assigned to either the treatment or the comparison group. For clients assigned to the treatment group, the system automatically informed CNS staff to offer TFS product. During their subsequent visits, CNS staff continued to offer the product until clients opened the account. For those who were assigned to the comparison group, CNS staff followed routine process, and did not offer the TFS product.

Experimental Design
Experimental Design
In an effort to increase savings among remittance receivers, at the onset of the project, CNS offered a saving account called "Tu Futuro Seguro" (TFS), or "Your Secure Future," to any remittance receivers in its four branches. The account paid 7 percent annually, compounded every month, with no restrictions on withdrawals or deposits. It had no starting fees but required the client to sign a non-binding agreement to save a predetermined amount of money for every remittance received. The client decided that amount, although CNS suggested US$20, US$50, or US$100. The client could also make deposits from any other source of income. As the name suggests, the account was marketed to clients as an account to save for emergencies, future economic shocks, and future illnesses. Though clients could withdraw funds, they were encouraged to use the money only for an emergency purpose.
