(1) The 100k figure from GWWC is unadjusted; once you apply the per annum discounts, GWWC estimates a pledge to be worth USD 15k. So CEARCH’s estimate is higher, but not by much.
(2) Similarly, GWWC’s 35.1 is unadjusted; in comparison, when we report a 16 year giving lifespan, that adjusting for various temporal discounts (e.g. attrition amongst pledgers).
(3) The 0.35 counterfactual adjustment (and all the estimates from that bulletpoint list) are for the global average /​ predominantly western pledger. The Asia-specific estimates are different; we don’t go into detail here, but we expect the counterfactual coefficient for Asian pledgers to be 0.62, or almost twice as much.

Hope that’s helpful.
Helpful indeed, and thanks for the spreadsheet!
