A) -.02
B) -1
C) -10
D) -500

9) Suppose Joe's utility for lobster (L) and soda (S) can be represented as U = L0.5 S0.5. Joe walks into a restaurant with $72. Lobsters cost $18 each and sodas cost $2 each. How much lobster and soda will Joe consume if he intends to spend all his money? (There are no tax and no tips.)

10) Richard receives government transfer payments and currently consumes 5 guns and 6 goose livers. Assume the price of guns decreases by 10% and the price of goose liver increases by 20%. The government raises Richard's transfer payments so he can still afford 5 guns and 6 goose livers. Does this constitute a true cost-of-living adjustment (COLA)?
A) No. Richard is overcompensated.
B) No. Richard is undercompensated.
C) Yes. The payment just achieves the right level of compensation.
D) Not enough information.

12) The above figure shows Bob's utility function. He currently has $100 of wealth, but there is a 50% chance that it could all be stolen. The midpoint of the chord that runs from zero and intersects the utility function where wealth is 100, represents Bob's
A) risk premium.
B) expected utility of receiving $50 with certainty.

D) risk neutrality.
E) None of the above
