(a)
Let output price be p. Then
Revenue (R) = py = p.(x11/2 + x21/2)
Cost (C) = F + w1.x1 + w2.x2
Cost minimization problem is:
Minimize C = F + w1.x1 + w2.x2
Subject to: R = p.(x11/2 + x21/2)
w1 > 0, w2 > 0, x1 > 0, x2 > 0, F > 0
Cost is minimized when MP1/MP2 = w1/w2
MP1 =
y/
x1
= (1/2) / (x11/2)
MP2 =
y/
x2
= (1/2) / (x21/2)
MP1/MP2 = [(1/2) / (x11/2)] / [(1/2) / (x21/2)] = (x2/x1)1/2 = w1/w2
Squaring,
x2/x1 = (w1/w2)2
So,
x1/x2 = (w2/w1)2
