| In [[economics]] and [[finance]], a '''risk-seeker''' or '''risk-lover''' is a person who has a preference ''for'' [[risk]]. While most [[investment|investors]] are considered [[risk averse|risk ''averse'']], one could view casino-goers as risk-seeking. If offered either $50 or a 50% each chance of either $100 or nothing, a risk-seeking person would prefer the gamble even though the gamble and the sure thing have the same [[expected value]]. In fact, the risk lover would be indifferent to accepting a less than 50% chance of $100 versus the sure $50 (how much less would depend on how risk loving the person is). The risk lover would also be indifferent between a 50% chance of each of $X and nothing versus the sure $50, where $X is some amount less than $100 (again, how much less would depend on how risk loving the person is).

| Risk-seeking behavior can be observed in the negative domain <math>x<0</math> for [[prospect theory]] value functions, where the functions are convex for <math>x<0</math> but concave for <math>x>0</math>.

| ==The risk-seeking utility function==
| |
| Choice under uncertainty is often characterized as the maximization of [[expected utility]]. Utility is often assumed to be a function of profit or final portfolio wealth, with a positive first [[derivative]]. The utility function whose expected value is maximized is [[convex function|convex]] for a risk-seeker, [[concave function|concave]] for a risk-averse agent, and linear for a [[risk neutral|risk-neutral]] agent. Its convexity in the risk-seeking case has the effect of causing a [[mean-preserving spread]] of any [[probability distribution]] of wealth outcomes to be preferred over the unspread distribution.
