An investor with an initial endowment of $ 16,000 is confronted with the following productivity curve: C= 240(16,000 - Co)0.5 where Co denotes consumption at present, and C consumption in the future. Assume the interest rate (for borrowing and lending) is 20%. The investor's utility function, from which it is possible to derive his indifference curves, is defined as: U(CO, C)=C0C1 What is the optimal allocation of consumption over the two periods? Co=15,600 C-13,000 None of the above Co=10,000 C1-24,000 Co=13,000 C-15,600
