We randomly distribute different kinds of explanatory material about the social insurance. In collaboration with the Social Insurance General Office of Mongolia, we create four sets of leaflets. All of the leaflets include general information about the public pension, along with the following additional information:
(Control) General information about the public pension only,
(Treatment 1) Survivors and disability pension, supplementary to the public pension,
(Treatment 2) Japanese official assistance for the public pension administration for consolidating the trust, and
(Treatment 3) Mobile banking payment for reducing the transaction cost.
