简要总结
In the last two decades, cash transfer (CT) programs have emerged as a popular approach to long-term poverty alleviation. While the main goal of cash transfer programs is to reduce poverty, they also have the potential to improve many development outcomes, such as health and education.
While many studies, mainly in Latin America and Asia, have investigated the impacts of CTs on poverty and food security and have, for the most part, found positive impacts, less is known about the impacts of CTs in Africa south of the Sahara, and, in particular, West Africa. Moreover, despite the fact that cash transfers have been shown to lead to decreases in poverty, improvements in household food security, and increases in health service utilization, impacts on children's nutritional status (including anthropometric measures) are generally small (Manley, Gitter, and Slavchevska 2013). Consequently, policymakers and governments are left with the question of how to design social safety nets, such as cash transfers, to achieve greater impact on diet quality, health, and nutrition.
The overall goal of this research is to generate evidence and knowledge on an integrated program implemented by the Government of Mali that includes a combination of cash transfers and targeted nutrition interventions. The information generated will inform program implementers and policymakers about best options to improve food security and nutrition among vulnerable groups and individuals in West Africa. Specifically, the main objectives of the research are
- To provide evidence on the contribution of integrated social transfer programs to enhancing household welfare, food security, dietary diversity, and maternal and child nutrition in West Africa.
- To test different features and combinations of cash transfers and targeted nutrition interventions, and assess their impact on food security and maternal and child nutrition and health outcomes in Mali.
- To generate knowledge regarding the pathways of impact of these different program packages, identify the most effective and efficient modalities in the context of Mali, and derive lessons learned for other countries in the region.
详细描述
The research entails two study designs: i) a repeated cross-sectional survey (baseline, midline and endline) in a sample of 1,440 children between 6 and 24 months of age, mainly to asses the program's impact on child nutrition and health outcomes; ii) a panel study following a cohort of 2,880 children over 3 years mainly focusing on the evaluation of household welfare outcomes. The study will be conducted in the 96 communes where the Jigisemejiri program is being implemented, situated in 5 regions of Mali: Sikasso, Koulikoro, Segou, Mopti and Kayes. Data will be collected at baseline (2014, T=0), midline (2016, T=~24 months) and endline (2018, T=~48 months).
The program is implemented for 48 months. The experimental group receives the cash transfer and group counselling intervention for 36 months. During the last 12 months the experimental group does not receive any intervention. The control group receives no intervention during the first 36 months, but receives the cash transfer and group counselling during the last 12 months. In a subsample of communes from the experimental group, villages were randomized to either receive Preventive Nutrition Packages (PNP) or nothing. The impact of PNP is analyzed by comparing villages that received PNP and villages that did not receive PNP during the last 12 months of the program.

研究组 & 干预措施
Control and comparison group -cash transfer program
The program is implemented during 48 months. During the first 36 months the control group does not receive any intervention. During the last 12 months eligible beneficiaries receive cash transfer and accompanying information sessions on health, child nutrition, household economics every three months (identical to experimental group).
干预措施: Cash distribution during the last 12 months (Other)

During the last 12 months eligible beneficiaries receive cash transfer and accompanying information sessions on health, child nutrition, household economics every three months (identical to experimental group).
干预措施: Accompanying information sessions on health, child nutrition, household economics and education during the last 12 months (Behavioral)
Jigisemejiri cash transfer program
Unconditional cash is distributed every 3 months to beneficiaries of the Jigisemejiri program. During cash handouts, information sessions on health, child nutrition, households economics and education are organized by local NGOs.
