borken utility
let's look at some cases where a person's utility function goes wrong. the utility function of a crazy homeless guy might be identically zero. in which case he'd maximize his happiness by being completely broke. yeah okay. a friend of mine insisted utility should increase faster than money. ie u(m)/m increases instead of being monotonically decreasing as is usually required. if so then he should go to vegas and bet all his money hoping to win a jackpot. which is exactly what compulsive gamblers do. interesting.
