Not if the marginal utility of money decreases as you have more.
If your utility function has convex parts then it might be possible, though. If you have $1000 but owe the Mafia $2000 and they're coming to collect, betting it all on black might be a good idea.
Hey, everyone! So I've been reading an article about the expected utility, apparently to figure out whether the risk is worth taking you multiply expected value of the outcome by it's probability.
And apparently insurance companies can make money because the expected utility of buying insurance is lower than it's price.
So why would buying insurance be the rational action? I mean intuitively it makes sense(you want to avoid the risk), but it doesn't seem to fit well with this idea. If insurance is almost by definition is worth slightly less than it's price, how is it worth buying?
(sorry if it's a dumb question)
