Household listing exercise: The investigators first identified and recruited households from selected villages to participate in the study. To identify these households, their survey partner, the Centre for Microfinance (CMF), used the "participatory rural appraisal" method to conduct a house-listing exercise (a social map) with residents of the village. This map identified household names, locations, and assets. Households in both treatment and control groups were then selected on the basis of two criteria which are discussed in the 'Eligibility Criteria' section.
