I used data from GWWC’s latest impact evaluation.
Below are my estimates for the recorded donations per pledger-year across time. I think GWWC is overestimating the initial decay in donations, and maybe underestimating the decay in donations in later years.
Thanks Vasco! Did you use GWWC latest data? Also, would value your thoughts on GWWC’s current analysis of recorded donations per pledger over time
