Under the Diamond-Dybvig framework, assume that individuals have the option to invest a fraction of their currency at a bank and put the remainder under the mattress. Suppose the variable I=fraction investead at the bank. Suppose the ex-ante utility is represented by: U= (1/2) u(C1) + (1/2) u(C2)
where C1 is consumption in period 1 and C2 is consumption in period 2, and
C1= 1 - (3/4) I
C2 = 1 + 3I
With u(C) = -1/C
Question: What is the optimal level of Investment, I*, the optimal level of period 1 consumption, C1*, the optimal level of period 2 consumption, C2*, and the optimal level of expected utility, U* ?
