The Main sample consists of those who accepted an HIV test, did not test as indeterminant, and who had non-missing information for age, the amount of the incentive received and have non-missing gps coordinates.

There are 284 individuals for which education (as measured by years of schooling) and/or the number of assets owned are missing. To include these individuals in the analysis we have imputed their education and assets as the mean (separately by gender) and include a dummy for whether they had missing asset information and missing education information in all specifications.
