The experiences we have as young children are widely recognized as having lasting impacts in later life. Supporting parents to engage with their children shows clear short-term developmental benefits and may have profound long-term effects on wellbeing, as well as health and achievement later in life.

There can be toxic levels of lead in all sorts of surprising products, including cosmetics. Lead exposure causes a global health burden comparable to malaria and HIV but receives less than 0.1% of their funding - even though malaria and HIV are themselves neglected diseases. Reducing lead exposure also seems feasible, given the strong historical success of advocacy campaigns. We evaluate Pure Earth’s program to reduce lead in cosmetics in Ghana, involving two years of advocacy and data collection followed by three years of enforcement support for a lead ban. We estimate it delivers 108 WELLBYs per $1,000 donated ($9.23 per WELLBY), making it the most cost-effective charity we have reviewed to-date. Optimistic assumptions increase this as high as 1,359 WELLBYs per $1,000 ($0.74 per WELLBY).
Mental health disorders like depression and anxiety are common and significantly impact wellbeing, yet mental healthcare remains underfunded in low-income countries. Psychotherapy is an effective treatment that can be delivered cheaply by lay counsellors. This in-depth report evaluates the cost-effectiveness of two charities providing such therapy in Africa: Friendship Bench and StrongMinds. We estimate that Friendship Bench has a cost-effectiveness of 49 WELLBYs per $1,000 donated ($21 per WELLBY), and StrongMinds has a cost-effectiveness of 40 WELLBYs per $1,000 ($25 per WELLBY). Our results show that both charities are 5-6 times more cost-effective than cash transfers at improving subjective wellbeing. This is the fourth iteration of our analysis, which includes new data and refined methods. Our results are similar to the last version of the report, and we conclude that these two organisations are the most cost-effective charities (which are also well-evidenced) we have evaluated to date.
Globally, 45 million children suffer from malnutrition, leading to 2.3 million child deaths
annually. But even for those who live, the experience of malnutrition can have lifelong impacts on physical and cognitive health and social-emotional development. There is a consensus on how best to address extreme malnutrition: feeding kids a standard
formula of peanut butter enhanced with vitamins and nutrients alongside basic medical care to prevent or treat infections. This intervention, known as community management of acute malnutrition (CMAM), saves lives and improves health and development. What this report seeks to find out is how effective it is at also improving happiness.
Iron deficiency may be a major contributing factor to mental illnesses such as depression. In this shallow exploration, we evaluate the cost-effectiveness of Fortify Health's work to address mass scale iron-deficiency anemia in India.​ Read the report to discover what effect adding a small amount of iron to wheat flour may have on happiness.
In November 2023, we published Version 3 of our psychotherapy analysis. This was a working report in which we estimated the effects of psychotherapy in low- and middle-income countries, as well as the cost-effectiveness of two psychotherapy charities: StrongMinds and Friendship Bench. In the first part of 2024, we have updated several parts of the analysis. This present, interim report, Version 3.5, describes the changes we have made so far. Our analysis suggests that both StrongMinds and Friendship Bench are among the most cost-effective charities we have evaluated to date. Friendship Bench has a cost-effectiveness of 53 WELLBYs per $1,000 donated and StrongMinds has a cost-effectiveness of 47 WELLBYs per $1,000 donated.
