Please answer question four.

Thank you.

C' A Parent's Consumption Parent's Consumption Uo Y' C' B' B Y'o Uo U1 C Y1 Yo C1 Co Child's Consumption Child's Consumption (a) (b)4. Panel (b) is identical to (a), except that this child chooses to consume at level Co rather than level C. In other words, he chooses to not voluntarily give any income (or consumption) to his parents. In other words, he chooses point B as his optimum tradeoff between his own consumption and his parents' consumption. This point is on indifference curve [Your answer here should be either Uo or U1, but not both.]
