Good point. There is a way to tell which recipients fall into which class though. Just ask them. That is, when giving to a recipient, instead of giving a bundle of cash, have him design an income stream for himself that has the same present value (to the donor) as the bundle of cash and give him that instead. This might increase transactions costs significantly, however. So I wonder if there is a way to tell whether on average charity recipients would rather borrow or save. Could someone do a study where you pick a random sample of charity recipients, have them design income streams for themselves (and have a trustworthy organization commit to giving them the income streams so they have proper incentives to report accurately) and then average out the results? This still isn't quite right, because it ignores future generations. Clearly a potential charity recipient who hasn't been born yet would prefer that I delay giving to charity, but the study won't be able to survey them, so the result will be biased towards giving too early. How to solve this problem?
