A decision-maker faces a lottery that gives her a final wealth of 1 dollar with probability 1/4, 3 dollars with probability 1/2, and 8 dollars with probability 1/4. (a) Suppose this decision-maker is an expected utility maximizer with von Neumann-Morgenstern utility u₁(x)=√x+1, where x is her final wealth. Find the risk premium associated with this lottery. (b) Now suppose that a second decision-maker who maximizes expected utility with von Neumann-Morgenstern utility u2(x)=√x faces the same lottery. Without calculating this decision-maker's risk premium, determine whether it is higher than, lower than, or the same as that for the decision-maker in part (a).

A decision-maker faces a lottery that gives her a final wealth of 1 dollar with probability 1/4,
3 dollars with probability 1/2, and 8 dollars with probability 1/4.
(a) Suppose this decision-maker is an expected utility maximizer with von Neumann-Morgenstern
utility u₁(x)=√x+1, where x is her final wealth. Find the risk premium associated
with this lottery.
(b) Now suppose that a second decision-maker who maximizes expected utility with von
Neumann-Morgenstern utility u2(x)=√x faces the same lottery. Without calculating
this decision-maker's risk premium, determine whether it is higher than, lower than, or
the same as that for the decision-maker in part (a).
