Abstract
Girls in developing countries face lack of information, stigma and fear surrounding a natural part of a woman’s life: menstruation. We explore how stigmas can be sustained, when plausibly universal. We test this in a field experiment with secondary school girls in Tanzania, using revealed preference and information treatment. In addition, we survey boys to understand information constraints and peer pressure.

Experimental Details
Interventions
Intervention(s)
The project has three main purposes: 1. Understand adolescent boys' attitudes and knowledge surrounding menstruation, and gender differences in knowledge. 2. The role of social coordination and peer pressure around a stigmatized subject, 3. Understand menstruation-related teasing behavior among adolescents, including using network analysis. These three aspects of the study are intended to be published separately.

Primary Outcomes
Primary Outcomes (end points)
There are three main outcomes:
- Boys' attitudes and knowledge surrounding menstruation, and gender differences in attitudes and knowledge
- The prevalence of menstruation-related teasing (from both perpetrator and victims point of view), stated reasons for teasing, and potential underreporting of teasing.
- Uptake of the AFRIpads in the social coordination experiment with four treatment groups
Primary Outcomes (explanation)
- For the boys and gender differences in knowledge: Primary outcomes will include all the questions listed in the questionnaire that capture beliefs and knowledge, analyzed individually and as indexes
- Share of girls who report having been teased. Share of boys who report teasing. Imputed share of boys who report been seen teasing according to the network analysis
- For the social coordination experiment: Uptake of the sanitary pad
Secondary Outcomes
Secondary Outcomes (end points)
Background variables such as value questions regarding if it's acceptable to tease a girl because she has her period, expectations of the future, psychosocial wellbeing, experience with menstruation, communication regarding menstruation
