Abstract
Our experiment investigates the fertility norms of Syrian migrants relocated in Türkiye due to the civil conflict that started in 2011, in relation to the norms of the native Turkish population. We implement an RCT evaluating an information intervention among a sample of Syrian refugees. Individuals are randomized into two treatment groups receiving information about natives’ and Syrians’ fertility and fertility intentions, and a pure control group receiving no information. We then compare the fertility intentions of the treated group and the control group immediately after the treatment and intentions and outcomes after six months. We also conduct heterogeneity analysis disciplined by a simple theoretical model of native-migrant interactions and descriptive norms. If our results align with the model predictions, we may also exploit a structural estimation to produce counterfactual scenarios on the convergence of social norms with and without native-migrant interaction.

Experimental Details

Interventions

Intervention(s)
We give two interventions. In the first intervention, individuals receive information about Syrian refugees’ fertility, using statistical data, figures, and smart graphs. In the second intervention, individuals receive information about Turkish natives’ fertility, using statistical data, figures, and smart graphs. We include all of the intervention materials with our pre-analysis plan.

Primary Outcomes

Primary Outcomes (end points)
Fertility intentions (intentions to have children overall, and in the next 3 years, as well as the ideal number of children), beliefs about the fertility of natives and Syrian migrants.
Primary Outcomes (explanation)
We include a full description in the pre-analysis plan.

Secondary Outcomes

Secondary Outcomes (end points)
Actual pregnancy, perceived stigma from not adhering to social norms on fertility.
Secondary Outcomes (explanation)
We include a full description in the pre-analysis plan.

Experimental Design

Experimental Design
The survey is administered by an enumerator, with the help of a tablet. During the survey, as indicated in the questionnaires attached in the pre-analysis plan material, we administer an information intervention. We do this by randomly divide our sample in 3 groups: one group receives no information, the second group receives information about Syrian refugees’ fertility, and the third group receives information about Turkish natives’ fertility, using statistical data, figures, and smart graphs. We then ask the remaining question about fertility, beliefs, and stigma. After 6 months we conduct a follow-up survey only including the questions after the treatment. This procedure is fully detailed in our pre-analysis plan.
