Question
Jamal has a utility function U= w!/2_where W
is his wealth in millions of dollars and Uis the
utility he obtains from that wealth. In the final
stage of a game show, the host offers Jamal a
choice between (A) $4 million for sure, or (B) a
gamble that pays $1 million with probability
0.6 and $9 million with probability 0.4.
a. Graph Jamal's utility function. Is he risk
averse? Explain.
b. Does A or B offer Jamal a higher expected
prize? Explain your reasoning with appropriate
calculations. (Hint:The expected value of a
random variable is the weighted average of the
possible outcomes, where the probabilities are
the weights.)
c. Does A or B offer Jamal a higher expected
utility? Again, show your calculations.
