Why would it be convex? Many opportunities have diminishing returns, which if I understand correctly would make the problem non-convex? E.g. the log(cash) example in the post
It is an optimisation problem, that’s for sure 😅
I heard people model giving as a knapsack problem, considering choosing yes/​no for fixed-sized grant applications, but I can’t find anything about it on the forum and I don’t know if it’s particularly useful.
I agree that the idea in this post is fairly obvious to people who have some knowledge of statistics (but not to people like me who last thought about stats many years ago). I’m a bit annoyed that I can’t answer the final two questions myself :/​
Do you have any ideas?
If opportunities have consistently diminishing returns (i.e. the second derivative is negative), then it’s convex. Giving opportunities may or may not actually be convex.
