2. A firm producing hockey sticks has a production function given by q = 2Vkl The price of labor is "w", the price of capital is "v". For any given level of output "q": a. Calculate the firm's long-run total, average and marginal cost function. b. Please show the cost function is homogeneous of degree 1 in input prices. c. Please show the cost function is concave in v. Suppose now that capital used for producing hockey sticks is fixed at "k1" in the short run. d. Calculate the firm's short-run total costs as a function of q, w, v, and k1.

I need solutions for C and D. I also attached the solution of A question for you.

2. A firm producing hockey sticks has a production function given by
q = 2Vkl
The price of labor is "w", the price of capital is "v". For any given level of
output "q":
a. Calculate the firm's long-run total, average and marginal cost function.
b. Please show the cost function is homogeneous of degree 1 in input
prices.
c. Please show the cost function is concave in v.
Suppose now that capital used for producing hockey sticks is fixed at "k1" in
the short run.
d. Calculate the firm's short-run total costs as a function of q, w, v, and k1.

2) The average cost function,
At equilibrium or optimal point,
AC = C/q
Slope of production function = Ratio of the price of inputs
MRTS = Price of labor / Price of capital
AC =
AC = VVVW

This is the average cost function.
The marginal cost function,
МС —
d C
VIvi
МС —
This is the marginal cost function.

k =
Put this value in the production function to find the value of the l as a function of g.
Consider the production function,
9 = 2
2Vivi
9 = 21
l =
2/w
This is the value of l. Put this value in the k function.
k =
2 w
k =
This is the value k.
To find the total cost function, put the value of l and k in the C function,
C = wl + vk
С — w
C = ViVw
