Consider a firm with production function:
LK
3
(a)
Find the marginal product of labor,
MPL. Next, indicate whether marginal product of
labor is decreasing, constant, or increasing in
labor. Explain or show your answer.
(b)
Find the marginal product of
capital, MPK. Next, indicate whether the marginal
product of capital is decreasing, constant, or
increasing in capital. Explain or show your answer.
(c)
Find and simplify the expression of the
marginal rate of technical substitution of labor for
capital, MRTSL.K. Next, indicate whether
MRT SL,K is decreasing, constant or
increasing in labor, and explain what does that this
MRTSL,K suggest about the shape of the
isoquants and the firm's ability to substitute
between inputs.
(d)
] Show whether the firm's production
function exhibits increasing, decreasing, or
constant returns to scale.
