17. Find the marginal productivity of labor (L) and
the marginal productivity of capital (K) from the production
function below.
(1)Q=ROOT LK
(2)Q=L^(2/3) *K^(1/3)
1.
Differentiate Q wrt K we get
Similarly by differentiating Q wrt L we get
MPL = Q/2L
MPK = Q / 2K
2.
Differentiating wrt L, we get
Differentiate Q wrt L, we get
MPL = 2Q/3L
MPK = Q / 3K
