For what it’s worth the Open Phil framework (with R&D discount factors removed) is looking at the effect of global growth, not growth in rich countries. That should attenuate the gap between their results and the results of modelling this just in LMICs. And I don’t know how big a big difference is, but to take it from my final estimate of 12X to 1000X would require growth promotion in LMICs to be over 80 times more cost effective than global growth promotion, which seems like a lot.
Agreed. I would like to see this done for LMICs and not rich countries as it seems that could make a big difference.

Yes and to be clear, I think the analysis is well done and think this adds to the debate, so I appreciate you doing this
