Expanding Our Livelihoods Research

We recently announced our expanding focus on livelihoods programs—interventions that help people in poverty earn more and improve their daily lives. We’ve researched and funded livelihoods programs for many years, but we’re taking a significant step forward by hiring a dedicated program officer to develop our long-term livelihoods strategy and explore the area more deeply.

Our new program officer will build on our existing work and lead the search for cost-effective livelihoods opportunities, such as community-driven development projects and programs that create indirect “spillover” benefits. We’re excited to explore more of the impactful programs that we—and our donors—have long cared about.

We dive into this work on a recent podcast episode with GiveWell CEO and co-founder Elie Hassenfeld and Senior Program Officer Julie Faller.

Our expanded focus on livelihoods programs touches on a fundamental question that’s central to all of our work. Because our funding is limited, we have to make choices about which programs to support, and those programs don’t all have the same outcomes—some increase people’s income, others prevent illness or death, and still others reduce pain and disability.

This requires us to grapple with a difficult question—how do we compare saving a life to substantially improving one? And because there is no “right” answer, how can we prioritize between programs that achieve different outcomes?

This is where our “moral weights” come in. Put simply, moral weights are the numerical values that we assign to various outcomes. In our cost-effectiveness models, we use moral weights to compare different outcomes and help us understand how much a particular program is likely to help people per dollar donated.

We view our moral weights as necessary tools, not absolute truths. We’ve refined them over the years, particularly the balance between health and income improvements, and we’ll adapt them for livelihoods-focused programs as part of this expansion. You can learn more about that in the recent podcast linked above, and you can explore our moral weights in our new blog post, “Apples, Oranges, and Outcomes.”

Grant Spotlight

Our grantmaking supports programs and research that aim to save and improve lives the most per dollar. Here’s a look at one recent example:

Where: Gombe, Nigeria
What: A malnutrition treatment program providing nutrient-dense therapeutic foods and medical care to severely malnourished children under five
Who: Taimaka
Why it matters: Acute malnutrition weakens children’s immune systems and can increase the risks of developmental delays, illness, and death. GiveWell’s grant will enable Taimaka to treat over 43,000 severely malnourished children who wouldn’t receive treatment otherwise.
Why this grant is promising: With a small additional monitoring grant, Taimaka will conduct surveys on several key program indicators (prevalence of malnutrition, baseline malnutrition treatment coverage, and mortality rates among children under five) that will help reduce uncertainties in our cost-effectiveness estimates. The results could lead to significant grantmaking opportunities in the next five to 10 years.
Funded by: Donations to GiveWell’s All Grants Fund and contributions from individual donors

    Presumably you’re aware of a paper published last week: https://www.nejm.org/doi/full/10.1056/NEJMoa2411262, entitled “Ivermectin to Control Malaria — A Cluster-Randomized Trial” but on the off-chance that you haven’t seen it yet, the intervention seems promising for GW to further investigate.

      Hi Arnold,

      Thanks for sharing this. Members of our malaria team have been following this trial and similar ones, and we’ve had conversations with some of the key researchers, including from the BOHEMIA trial you shared and another recent ivermectin trial, RIMDAMAL II.

      While we haven’t looked deeply into all the evidence yet, our current understanding is that the evidence for ivermectin’s effectiveness is mixed. The RIMDAMAL II trial did not find significant evidence of an effect on malaria, while the BOHEMIA trial did. Drugs like ivermectin and nitisinone, which also has a mosquito-killing effect, are on our list to investigate more deeply in the future, but our malaria researchers are currently focused primarily on nets, seasonal malaria chemoprevention, and case management.
