|May 2014||To Charge or Not to Charge: Evidence from a Health Products Experiment in Uganda|
with Greg Fischer, Dean Karlan, Margaret McConnell: w20170
In a field experiment in Uganda, a free distribution of three health products lowers subsequent demand relative to a sale distribution. This contrasts with work on insecticide-treated bed nets, highlighting the importance of product characteristics in determining pricing policy. We put forward a model to illustrate the potential tension between two of these important factors, learning and anchoring, and then test this model with three products selected specifically for their variation in the scope for learning. We find the rank order of percentage change of shifts in demand matches theoretical predictions, although the differences are not statistically significant, and only two of three pairwise comparisons match when the reductions are specified in percent terms. These results highlight t...
|June 2013||Mixed Method Evaluation of a Passive mHealth Sexual Information Texting Service in Uganda|
with Julian C. Jamison, Dean Karlan: w19107
We evaluate the impact of a health information intervention implemented through mobile phones, using a clustered randomized control trial augmented by qualitative interviews. The intervention aimed to improve sexual health knowledge and shift individuals towards safer sexual behavior by providing reliable information about sexual health. The novel technology designed by Google and Grameen Technology Center provided automated searches of an advice database on topics requested by users via SMS. It was offered by MTN Uganda at no cost to users. Quantitative survey results allow us to reject the hypothesis that improving access to information would increase knowledge and shift behavior to less risky sexual activities. In fact, we find that the service led to an increase in promiscuity, and no ...
