Vasco Grilo🔸 answers Cost effectiveness of Longtermist interventions

[Vasco Grilo🔸]

Thanks for the question, Kaleem.

The Centre for Exploratory Altruism Research (CEARCH) estimated policy advocacy to increase resilience to global agricultural crises is 30 times as cost-effective as GiveWell’s top charities. I adjusted their estimate, and concluded it is 4.08 times as cost-effective as GiveWell’s top charities.

CEARCH estimated lobbying for nuclear arsenal limitation is 5 k times as cost-effective as GiveWell’s top charities. I guess the actual cost-effectiveness is more like 10 times that of GiveWell’s top charities.

I estimated epidemic/​pandemic preparedness is 24.3 % (= ¹⁄₄.12) as cost-effective as GiveWell’s top charities.

I think the best animal welfare interventions are way more cost-effective than the best in global health and development:

• I estimated broiler welfare and cage-free campaigns are 168 and 462 times as cost-effective as GiveWell’s top charities.

• I estimated the Shrimp Welfare Project is 64.3 k times as cost-effective as GiveWell’s top charities.
