This study examines the health impacts of community-based conditional cash transfers in Tanzania. The findings show that the program had positive effects on health clinic visits, health insurance take-up, and use of public facilities. However, satisfaction measures did not show sustained effects.

To date, limited evidence base(a) from Africa, conditioning on health(b) relying on local communities to run program / deliver payments
Operational experience and contextual expertise International expertise on cash transfers and on impact evaluation Initial funding for the program & evaluation
How big was it? ≈ ≈
What households received (in 2010) per child (US$3) per month per adult (US$6) per month on average
Who did what • Identification of the poor…by communities • Distribution of payments…by communities • Monitoring of conditions…by communities
Summary of Findings • Initial (after 18 mos.) positive impacts on health clinic visits disappeared by 2.5 years • Health benefits take 2.5 years to materialize (not present at 18 mos.), and are mostly driven by young children aged 0‐5 (not elderly) • Large increase in use of health insurance • Shift toward using publicly‐provided healthcare • Initial (after 18 mos.) increase in satisfaction with healthcare disappeared by 2.5 years (habituation) • No increase in objective healthcare quality

How difference-in-differences works Outcome Roll out program Diff at endline Comparison Treatment Diff at baseline Difference at endline - Difference at baseline Impact of program Time Baseline Endline
Difference-in-differences Specification • i indexes individuals (or households, for household-level outcomes) • t indexes the survey round • hit is a health outcome • αi are individual fixed effects • Ti=1 in CCT treatment group (zero otherwise) • 2011t=1 at time of midline survey (18-21 months of transfers) • 2012t=1 at time of endline survey (31-34 months of transfers)
Two sub-samples among our poor HHs • Carried out a principal components analysis (PCA) using dummy variables for ownership of 13 HH assets • Took the first principal component as our index of HH wealth • Households with above-median wealth: “moderately poor” • Households with below-median wealth: “extremely poor”
What were the impacts of the program on health and health-related outcomes for the poor?
Outcome: Participation in government-run health insurance program
Multiple Hypothesis Testing • Use three methods to correct • Median significant results after correction
Conclusions • Conditional cash transfers effectively increase health for children • Initial increase in clinic visits (conditions) • Major increase in health insurance take-up (not conditioned) • Beware of satisfaction measures: Effects may disappear
