As social protection cash transfer programs expand, they face demands to deliver greater public value as well as increase cost-effectiveness. There is evidence that insights from behavioral science- the science of how humans make decisions and take actions- can be used to achieve these objectives. Ongoing partnerships between ideas42, the World Bank, and the government of Tanzania have been working to enhance the effectiveness of cash transfer programs through a process of design, testing, and analysis. Research from the field of behavioral science along with a process of user-testing and iteration were used to design context-specific packages of interventions to increase the cost effectiveness of such cash transfer programs. The upcoming RCT will survey about 2880 individuals in 64 in Tanzania at baseline and again 6 months later during a follow-up to estimate if light-touch, low-cost interventions can improve short-term outcomes that may lead to more productive investments and better economic well-being in the long term.

Experimental Details


Goal setting activity- benefiaries select a goal from pre-specified images or draw their own goal
Plan making activity- beneficiaries determine how much their goal will cost and how much they wish to save from each transfer.
Tracking activity- beneficiaries may track (by checking) if they have saved the desired amount after each transfer
Partitioning pouch- Beneficiaries are given a pouch they can use to seperate the cash they intend to save from the cash they intend to use for consumption
Self-affirmation activity where beneficiaries affirm their values before setting a goal

Experimental Design

Experimental Design
This experiment is a cluster randomized controlled trial in which half of the clusters (locations) will be assigned to the control group (recieving cash as normal) and half of the clusters will be assigned to the treatment group (cash plus behavioral activities).
