How do you apply isoelastic utility to real world consumption/income values? For, say, calculating “equivalent sacrifice” donation amounts for people with different incomes.
When I’ve tried to apply the formula, incomes as different as $10k and $80k both seem to equal “almost 2.0 utility”, and I don’t know what to do with this.
Thanks for sharing this, I really enjoyed it.
I did some “customer” research around effective giving a year or so back and found some similar themes.
Engaged EAs already seem to have what they need. Most other people give small amounts to affirm/signal their values, with little regard for impact. It is indeed easy to think of things that “should exist” but people don’t want!
