Seconding this! I would also be very curious about what the multiplier is if you discount giving in future years, ideally as a chart of multiplier vs annual discount rate.
I haven’t looked at this model, but in GWWC’s 2020–2022 Impact evaluation, you can change the annual discount rate here or here (and other key parameters in cells nearby)
If I understand correctly, a ~10% yearly discount rate ~halves the expected value of a pledge and changes the best guess non-marginal multiplier from 30x to 23x
I think the equivalent in this model is here and a ~10% discount rate changes the marginal multiplier from 14x to 8x
