The study has two main phases. In the first, we seek to evaluate the effect of different information nudges on Sisbén registration. In the second phase, we aim to identify the dynamics of participants’ social capital and if it correlates with Sisbén take-up or not.
The first stage consists of an RCT. We will send the participants a baseline survey that includes screening questions. We will assign eligible participants, who from now on we will call “Generation 0”, into three groups, one control and two treatments (see Figure 1). Participants assigned to the control group will not receive any information, besides the baseline and endline survey. Participants in Treatment 1 group will receive informational nudges via SMS. Participants in Treatment group 2 will receive information through WhatsApp. The content of the messages is the same for the two treatment groups.
The second phase of the study will complement the first phase’s intervention by mapping out migrant networks and information diffusion among those networks. In this second phase, we will send eligible participants -participants that already requested Sibén- three to four messages inviting them to ask other Venezuelans to contact us and be part of the study. From now on, we will refer to this first group of participants as “Generation 1.” Each participant from Generation 1 will receive a unique code that referrals must send us through WhatsApp to register in the study.
