Givewell has pretty in depth reports on the charities they recommend. They’ve spent a very large amount of time trying to figure out the efficacy of giveDirectly, largely because it is effectively an infinite sink that all other philanthropic activities can be compared against. Interestingly givewell just recently demoted giveDirectly to instead recommend a charity that does cash handouts to parents who get their children vaccinated. I’ve got the report on my reading list but haven’t had a chance yet.
