International development organisations and NGOs are all looking for effective interventions to alleviate chronic poverty in Africa. Is cash transfer headache or breakthrough?
Beyond reducing poverty, finding the right methods to improve the scope of project implementation and bring satisfying outcome is the key element of deciding the success of charitable organisations and development institutions. This evaluation report(policy brief) on cash transfer by GiveDirectly conducted in 2013 is an example of seeking the right method, in my opinion.
The evaluation was conducted by Johannes Haushofer and Jeremy Shapiro. The report makes it clear that Jeremy Shapiro who participated in the evaluation is a co-founder and former director of GiveDirectly.
Overall, the result of the intervention is encouraging. There was a significant increase in asset value, consumption, business & livestock income, food security, psychological well-being, and female empowerment. However, long-term outcomes such as health and education didn’t show a significant increase in this result.
Here are the nuts and bolts of the plan (see table below).
- Households meeting a basic eligibility criterion(living in a thatched roof house) were randomly chosen as the recipient.
- Treatment and control groups were set for impact comparison.
- Recipients were told they can spend the money as freely as they wish.
- The cash transfer is unconditional. That is, recipients do not have to satisfy any condition in order to receive money.
- Three design features were added and randomised.
- woman vs. man recipient
- monthly vs. lump-sum transfer
- large vs. small amount(USD1,100 vs. USD300)
With the randomisation like a, b, and c, the evaluation provides more opportunities to improve the quality of the outcome. Table below is the result of the evaluation.
Control group is in column 1 and the treatment group, the recipient, is in column 2. There are significant increases in treatment effect with more than 5% significance(* denotes significance at 10 pct., ** at 5 pct., and *** at 1 pct. level). Put simply, three asterisks means the outcome is statistically significant.
Significant increase by USD279 in asset value, USD36 in consumption(food, medical, social expenses, in particular), and USD17 increase in business and livestock income.
Significant increase by 0.25SD(standard deviation) in food security, and 0.20SD in psychological well-being, 0.23SD in female empowerment, compared to control group.
Monthly payment has an influence in food security with 0.26SD.
There is little evidence that female/male recipient makes significant difference.
Spillover effect is small or not significant with the exception of women empowerment. The result implies that treatment group shows an effect from the intervention relative to control group.
Some common and critical questions on cash transfer are:
- won’t it be spent on gambling, alcohol and the like?
- won’t it be just one time impact? Does it bring sustainability to the recipient households?
- won’t the cash inflow affect the price increase in the village?
My thought on this evaluation is that it’s meticulously well designed evaluation. I’m not very familiar with the complication of having multitude of randomised variables as in this report. But it’s certain that various results from those variables can help guide how to design an improved project/programme afterwards. Somewhat surprising fact, however, is that this type of report is not as common as it should. It’ll be great if more and more NGOs and other agencies use an impact evaluation/randomized controlled trials like in this case.
Couple of boys belly downed on the side road near the entrance of the biggest shopping centre in the city. I tried to look at what they were doing in that position. They were sipping water from the ground with their face down so as not to get their hands dirty. That didn’t shock me … Continue reading “Beneath the number”
As a foreigner working in development field in developing countries, I gotta have a dilemma that potentially compromises the success of the projects: am I living here like a foreigner or like a local? For the projects to be effective, I must think like the locals. And so as to do so, I first have … Continue reading “My extravagant life and its relationship to poverty reduction”
