August 2018Keep It Simple: A Field Experiment on Information Sharing in Social Networks
with Marcel Fafchamps, Pedro C. Vicente: w24908
SMS information campaigns are increasingly used for policy. To investigate their effectiveness, we conduct a lab-in-the-field experiment to study information sharing through mobile phone messages. Subjects are rural households in Mozambique who have access to mobile money. In the base treatment, subjects receive an SMS containing information on how to redeem a voucher. They can share this information with other exogeneously assigned subjects. We find that few participants redeem the voucher. They nonetheless share it with others and many share information they do not use themselves. Information is shared more when communication is anonymous and we find no evidence of homophily in information sharing. We introduce treatments to vary the cost of sending a message, shame those who do not send...
October 2014Directed Giving: Evidence from an Inter-Household Transfer Experiment
with Dan Silverman, Dean Yang: w20605
We investigate the determinants of giving in a lab-in-the-field experiment with large stakes. Study participants in urban Mozambique play dictator games where their counterpart is the closest person to them outside their household. When given the option, dictators do a large fraction of giving in kind (in the form of goods) rather than cash. In addition, they share more in total when they have the option of giving in kind, compared to giving that can only be in cash. Qualitative post-experiment responses suggest that this effect is driven by a desire to control how recipients use gifted resources. Standard economic determinants such as the rate of return to giving and the size of the endowment also affect giving, but the effects of even large changes in these determinants are significantly...
