keeping the doctor away

New research investigates the effect of preventive health using field experiments.

Results have important policy conclusions:
1. poor households do not take preventative health measures because they are unwilling to pay for them.
2. information campaigns have relatively low impact
3. peer effects matter, however, only when information asymmetry is likely to matter
