> Procedure [of Study 1]: Once both partners completed the intake survey (month 0), we randomly assigned couples to one of three bank account structure conditions. We informed couples via e- mail and provided condition-specific instructions. In the Separate Condition, we instructed couples to continue using separate checking and savings accounts and to not open joint checking and savings accounts, for the duration of the 2-year experiment. In the Joint Condition, we instructed couples to open joint checking and/or savings account(s) (within 1 month of them receiving these instruc- tions), use those joint account(s), and discontinue using their separate account(s) for the duration of the 2-year experiment. In the No-Intervention Condition, we told couples that they could manage their money however they liked for the duration of the 2-year experiment.
