Intervention (Public)
|
Before
1. Inviter Treatment (n=600) – This group will view the Sharing List and can invite up to five women on the list to share a meal (invitation delivered by enumerators).
2. Vouchers + Inviter Treatment (n=600) – Recipients will receive 7 USD (8% median monthly income) vouchers, redeemable at several local vendors selling perishable produce, and the Inviter Treatment.
3. Control (n=400) – This group will not receive any intervention.
Within treatments 1 and 2, participants will view one of three types of Sharing Lists: within-SES (all Invitees have a straw roof), cross-SES (no Invitees have a straw roof), or a random selection of women (for each of these three groups, n=200 in treatment 1, and n=200 in treatment 2).

Experimental Design (Public)
|
Before
My RCT will include two intervention arms that each attempt to solve barriers to inviting somebody to share a meal: a food price subsidy to solve budgetary concerns, and information about who else in the village would like to share meals to solve social concerns, such as fear that an invitation might be rejected. I will first recruit a sample of 2,600 women who moved to the village after the age of 14 but no more than 20 years ago (Baseline Sample). I will select a 1,600-person subset of the Baseline Sample for the intervention (Intervention Sample), selected if they have a straw roof (proxy for low-income) since budgets are more likely to constrain low-income women. I will offer Baseline Sample participants who are not selected for the Intervention Sample the opportunity to be an Invitee, who add their name to a list of women who are interested in sharing meals with other women in the village more often (Sharing List). The rest of the study will be conducted with the Intervention Sample, who will be randomized into the Inviter, Inviter + Voucher, or Control treatment arms.
Data:
Baseline Survey: collected with all 2600 participants
Treatment Allocation Survey (one month after Baseline): collected with the Intervention Sample
Endline Survey (one month after treatment): collected with the Intervention Sample
Food Diaries: Intervention Sample participants will fill out a pen-and-paper food diary, where they can mark from a list of food options what they consume each day over the course of two weeks. They can also mark if each meal was shared on the same diary.

I will first recruit a sample of 3,600 women who moved to the village after the age of 14 but no more than 20 years ago (Baseline Sample). I will select a 1,600-person subset of the Baseline Sample for the intervention (Intervention Sample), selected if they are in the bottom 80% of an SES index (proxy for low-income) since budgets are more likely to constrain low-income women. I will offer 1,000 Baseline Sample participants who are not selected for the Intervention Sample the opportunity to be an Invitee, who add their name to a list of women who are interested in sharing meals with other women in the village more often (Sharing List). The rest of the study will be conducted with the Intervention Sample, who will be randomized into the Inviter, Inviter + Voucher, or Control treatment arms.

Randomization Method
|
Before
All women without straw roofs are assigned to the Invitee treatment
Women with straw roofs randomized into Inviter, Inviter + Voucher, Invitee, or Control via randomization in office by a computer
|
After
500 women in the bottom 80% of an SES index will be randomly assigned to the Invitee treatment; and 500 women in the top 20% of the SES index will be randomly assigned to the Invitee treatment
Women in the bottom 80% of an SES index will be randomized into Inviter, Inviter + Voucher, Invitee, or Control via randomization in office by a computer
The remaining women will also be in the Control group, but will not be interviewed in the Treatment Allocation survey, or one-month follow-up Endling.
