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 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 shifts in demand matches with the theoretical prediction, although the differences are not statistically significant.

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.

In fact, we find that the service led to an increase in promiscuity, and no ...
