It is estimated that up to 23% of schoolgirls miss school during their menstrual periods in Sierra Leone (Sommer et al, 2012). Lack of access to adequate and affordable menstrual hygiene products is one of the reasons for missing school. Through our field experiment in rural Sierra Leone, we will study the effects of providing reusable pads to school girls on objective outcomes (school attendance and participation) and subjective measures (competition and self-esteem).
