Consider a consumer who can borrow or lend freely at an interest rate of 100% per period of time (think of the period as being, say, 30 years, a bit like with a mortgage). So r= 1.0, or 100%. The consumer's two-period utility function is: U=In(ct) + (1/2)In(Ct+1) The consumer earn Y=100 each period, so Y₁-100 and Yt+1 also equals 100. If this consumer is behaving optimally, trying to maximize her lifetime utility subject to the IBC, what's her consumption in period t?

Question
Consider a consumer who can borrow or lend freely at an interest rate of 100% per period of time (think of the period as being, say, 30 years, a bit like with a mortgage). So r = 1.0, or 100%.
The consumer's two-period utility function is:
U = In(ct) + (1/2)In(Ct+1)
The consumer earn Y=100 each period, so Y₁=100 and Yt+1 also equals 100.
If this consumer is behaving optimally, trying to maximize her lifetime utility subject to the IBC, what's her consumption in period t?
