SURNAME, Name: __________________________ Number: ______________________ 9. [3 Marks] Milk producers operate under the rules of Perfect Competition. All firms have total costs C = q 2 − nq + 25. This is a Decreasing Cost Industry. Market demand is Q = 18 − P . The Government of Ontario levies a subsidy of \$4.00 per litre of milk. Provide the usual pair of fully labelled diagrams showing “The Firm” and “The Industry” along with supplementary calculations to illustrate and quantify the response A , B and C to this per-unit subsidy. q0 = 5: p = 10 – n, Q = 5n, Q = 18 – p, n0 = 2, p0 = 8, Q0 = 10, mc0 = 2q – 2, S0 = p + 2 mc1 = 2q – 2 – 4, S1 = p + 6, p1 = 6, q1 = 6, Q1 = 12 q2 = 5, p = 6 – n, Q = 5n, Q = 18 – p, n2 = 3, p2 = 3, Q2 = 15 8 0 1 2 3 4 5 6 7 12 0 1 2 3 4 5 6 7 8 9 10 11 quantity price MC0 AC0 MC1 MC2 AC2 p0 p1 p2 18 0 2 4 6 8 10 12 14 16 12 0 1 2 3 4 5 6 7 8 9 10 11 X Axis price S0 = P + 2 S1 = P + 6 S2

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
