1. What relative amounts of capital and labor will be employed to
maximize output?
a. equal amounts of capital and labor
b. four times as much labor as capital
c. twice as much capital as labor
d. none of the above
Q = K^1/2L^1/2
Marginal Product of capital=MPK=dQ/dK=1/2*K^(-1/2)*L^1/2=0.5K^(-0.5)L^0.5
Marginal Product of labor=MPL=dQ/dL=K^1/2*(1/2)*L^(-1/2)=0.5K^0.5L^(-0.5)
For profit maximization, firm will employ its capital and labor such that
MPK/WK=MPL/WL
