Problem
Multiproduct Firm
Ralph uses three inputs (denoted z1 = 0, z2 = 0 and z3 = 0) to produce two products (denoted q1 and q2). Respective factor prices are P1 = 1,P2 = 5 and P3 = 2. Technology requires z1+z3 = q1 and z2 + z3 = q2.
(a) Write down the optimization program to determine Ralph's cost, C(q;P).
(b) Determine the first product's marginal cost if q1
(c) Determine the first product's marginal cost if q1 > q2.
(d) Explain your findings intuitively, and in terms of the shadow prices on the technology constraints.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
