Question

Suppose the production function is given by Q (L,k)=L 3\2 k1\2 assuming capital fixed find APL and MPL

Answer 1

$AP_L=\frac{TP}{L}$

$AP_L=\frac{L^{\frac{3}{2}} K^{\frac{1}{2}}}{L}=(LK)^{\frac{1}{2}}$

$MP_L=\frac{\varDelta TP_L}{ \varDelta L}$

$MP_L=\frac{3}{2}L^{\frac{1}{2}}K^{\frac{1}{2}}$
