"One of the more important things I’ve changed my mind about recently is the best cause to donate to. I now put the most credence on the possibility that the best option is donating to a fund that invests the money and disburses strategically in the future. I will refer to this as “giving later”, though I actually support giving now to a donor-advised fund set up to disburse in the future, for the value that donating now can have for encouraging others to donate (and because of the risk that even if one thinks one will donate later, one will at some point change one’s mind).
There are several reasons why I prefer a fund that disburses in the future. First, I believe people currently discount the future too much (see hyperbolic discounting, climate change). If people discount the future, that causes the rate of return on investments to always be higher than the growth rate (else people would not be willing to invest). In economics, the Ramsey equation is often used to determine how much a social planner should discount future consumption. It is specified by r=ηg+δ, where r is the real rate of return on investment, η is the extent to which marginal utility decreases with consumption, g is the growth rate, and δ represents pure time preferences. Unless one personally puts a particularly high value on δ, it makes sense to invest today and spend later to take advantage of the gap between the real rate of return on investment (~7%) and the growth rate (~3-4%)."
