Consider a simple three-period model where consumer's utility is a function of consumption in three periods. Let the utility function be U(x, y, z) = Inx+lny+Inz where x, y, and z are the consumption in period 1, 2 and 3, respectively. The consumer is also endowed with a budget B at the beginning of the period 1. Let "r" denote a market interest rate at which the consumer can choose to borrow or lend across three periods. The consumer's intertemporal budget constraint is that x and the present values of y and z are added up to B. Solve this intertemporal utility maximization problem and give an economic interpretation on your results. Construct only the Bordered Hessian Matrix.
