There are 2 goods, x and y and 2 consumers, A and B UA = xy and UB = xiyi The production functions of good x and good y are fx = (Kr, Lx)i and fy = (Ky, Ly) i There are 16 units of Land 16 units of Kin the economy. It can be shown that the PPF for this economy is given by y = 16 - x If 8 units of L and 8 units of Kare used to produce x, and both A and B receive equal shares of both goods, would this allocation be efficient? A. Yes OB. NOThis economy satisfies 0 A. Productive efficiency only 0 B. Consumption efficiency only 0 C. Allocatiye efficiency only 0 D. Pareto efficiency 0 E.
