Notes: Table reports means and standard deviations for characteristics of BCS bank’s Tuticuenta account holders included and not included in the experimental sample. Youth who opened a Tuticuenta account in February, March or April of 2013 in any of the 263 bank branches nationwide are initially eligible to participate in the experiment. A total of 14,788 youth are part of this initial selection. We impose two additional restrictions on final experimental sample: having a registered a personal cellphone number in the account application form and among youths with a cellphone, we only included youths who opened a Tuticuenta account in a branch were at least three other youths opened Tuticuenta accounts.
