Hi Can you please help me to do this. I have tried doing MPL/PL=PMK/PK but I could not get the same answers . I don't know whether it is my math or if I have the wrong formula to LCCI (Least Cost Combination) Thank you
. 1. A firm produces according to the following production function: Q = K0.25L0.5 . Suppose that the price of K is $4 per unit, and the price of L is $6 per unit. When L=5 and K=10, is the firm minimizing costs?
No, the least cost combination of inputs (LCCI) produces LCCI labor = 0.066 LCCI capital = 0.025 Use more labor or less capital
2. A firm produces according to the following production function: Q = K0.33L0.5. Suppose that the price of K is $6 per unit, and the price of L is $12.5 per unit. When L=15 and K=13, is the firm minimizing costs?
No, the least cost combination of inputs (LCCI) produces LCCI labor = 0.024 LCCI capital = 0.038 Use more capital or less labor
(1)
Q = K0.25L0.5
MPL = Q/L = 0.5 x K0.25 / L0.5 = 0.5 x (10)0.25 / (5)0.5 = 0.5 x 1.78 / 2.24 = 0.4
MPK = Q/K = 0.25 x L0.5 / K0.75 = 0.25 x (5)0.5 / (10)0.75 = 0.25 x 2.24 / 5.62 = 3.15
MPL/PL = 0.4/6 = 0.067
MPK/PK = 3.15/4 = 0.7875
Since (MPL/PL) < (MPK/PK), currently firm is using too less labor and too much capital. So cost will be minimized if firm uses more labor and less capital.
(2)
Q = K0.33L0.5
MPL = Q/L = 0.5 x K0.33 / L0.5 = 0.5 x (13)0.33 / (15)0.5 = 0.5 x 2.33 / 3.87 = 0.3
MPK = Q/K = 0.33 x L0.5 / K0.67 = 0.33 x (15)0.5 / (13)0.67 = 0.33 x 3.87 / 5.58 = 0.23
MPL/PL = 0.3/12.5 = 0.024
MPK/PK = 0.23/6 = 0.038
Since (MPL/PL) < (MPK/PK), currently firm is using too less labor and too much capital. So cost will be minimized if firm uses more labor and less capital.
