Abstract
We test an alternative survey method to the standard face-to-face interview, which we call in-group individual survey, in which respondents are grouped together and answer questions posed by a common enumerator directly on a tablet provided to them. We use a randomized control trial design in which the same questionnaire is randomly administered either in-group or on a one-to-one basis. We compare the relative performance of the two methods to examine whether the in-group survey: 1) elicits different responses to sensitive questions; 2) is less subject to enumerator bias; 3) generates some within-group conformity bias; 4) is less costly; and 5) raises specific technical issues.

Interventions

Intervention(s)
We take advantage of an RCT in Benin in which respondents are randomly assigned to receive a business training. Participants are grouped together to receive the training. In this context, we administer a survey at the beginning of the session and compare the results with those obtained in face-to-face interviews.

Primary Outcomes

Primary Outcomes (end points)
Comparison of attrition rates, socioeconomic characteristics (i.e., number of children, father/mother alive), women empowerment (including decision making and goal setting), intra-household allocation of chores and expenses, gender norms

Experimental Design

Experimental Design
Women invited to the training program are randomly selected from a sample of pineapple producing households who applied for a subsidy to start or expand a pineapple production (these households typically include a man producing pineapple and in half of the cases a woman producing as well). A control group is selected among the initial pool of applicants.
Data collection occured in two waves: baseline in 2020 and endline in 2022.
Experimental Design Details
the 673 women invited to the training program are randomly selected from a sample of pineapple producing households who applied for a subsidy to start or expand a pineapple production (these households typically include a man producing pineapple and in half of the cases a woman producing as well). A control group of 336 women is selected among the initial pool of applicants.
