The representative firm has technology given by Y = zK 1 / 3 N 2 / 3 . There is a government that sets its expenditure level at a value G 0. (a) Define a CE for this economy. (b) Find the CE values ( C * , * ,N * ,T * ,Y * ,w * ) given parameters h = 14, z = 1, K = 15 , 625, and G = 0. Exercise 2 (15 points) Consider the same economy described in Exercise 1. (a) Set up the equivalent social planners problem. (b) Solve it and show that it gives the same results as those from Exercise 1, part (b). Exercise 3 (15 points) Repeat Exercise 1, part (b), but now assume that G = 10. Go as far as you can into solving for the CE values. If you can find them, how different is the allocation to that of Exercise 1, part (b)? If you cannotvalues....
