We’re always excited when we can use the media to tell people about GiveWell’s work—we encourage you to check out our recent feature on the EconTalk podcast! In this episode, GiveWell’s CEO Elie Hassenfeld spoke with EconTalk’s Russ Roberts to discuss GiveWell’s history and how we strive to find the most charitable “bang for your buck.” The conversation covered how and why GiveWell was founded, our methods for determining top charities and other high-impact grant opportunities, and the dangers of relying too heavily on data.

We’ve recently published a number of new research pages—below are a few highlights. If you’d like to sign up for email updates whenever we publish new research materials, you can do so here.

Perennial malaria chemoprevention in the Democratic Republic of the Congo

In November 2022, GiveWell made a $6.2 million grant to PATH to conduct a two-year implementation pilot of perennial malaria chemoprevention (PMC)1Note: Intermittent preventive treatment in infants is now called perennial malaria chemoprevention. jQuery(‘#footnote_plugin_tooltip_14396_1_1’).tooltip({ tip: ‘#footnote_plugin_tooltip_text_14396_1_1’, tipClass: ‘footnote_tooltip’, effect: ‘fade’, predelay: 0, fadeInSpeed: 200, delay: 400, fadeOutSpeed: 200, position: ‘top right’, relative: true, offset: [10, 10], }); in the Democratic Republic of the Congo (DRC), where malaria is a leading cause of death among young children. PMC is the provision of preventive antimalarial medicine to children under the age of two at routine vaccination visits. We believe this grant to be highly cost-effective and expect PATH will reach over 180,000 infants during the pilot. We believe that this pilot, by demonstrating the possibility for successful implementation in DRC, has the potential to accelerate PMC support from other donors, which could lead to roughly 900,000 infants receiving PMC over the next decade.
