Derive the per-worker production function for this economy if Y=zK2/3N1/3.

Y=10.KO.5 L0.5 K starts at 500, L at 50, Investment 0.10Y, Depreciation 0.05K An alien invasion leads to a reduction in labour to 25 but no capital is damaged. What happens to the marginal product of labour? Increase O stays the same Decrease

whats the difference between marginal physical product (MPP) and the marginal rate of subsitution (MRS)?

Suppose the per-worker production function is: y = A(1-gA) Where ga is the fraction of all workers that produce technologies. Further, suppose the growth of technology is given by the following equation growth of A = (g//m)(L) Suppose L = 1 and m = 7, and that initially ga = 0.7. If ga fell to 0.8 the level of output per %3D worker would: fall Impossible to say rise stay the same
