I don’t follow this comment. You’re saying Vasco gives you X now, 2X to be paid back after k years. You plan to spend X/2 now, and lock up X/2, but somehow borrow 3/(2X) money now, such that you can pay the full amount back in k years?
Nitpick. (3/2) X, not 3/(2 X).
If one expects investments to grow more (in real terms) than the product “cost-effectiveness of altruistic spending conditional on survival”*”probability of survival” will decrease, it makes sense to invest as much as possible now, and then donate as much as possible later. Funders of altruistic interventions should try to equalise the product I just mentioned across years (otherwise, they should move their spending from the worst to the best years).
