Monopoly – short run equilibrium
1. Monopoly – short run equilibrium
• MC = MR
• Slope of the MC > slope of the MR at the point of
intersection
• Example
Q = 50 – 0.5P
TC = 50 + 40Q
What is TR? MR?MC? Profit maximization out put?
2. • TR
Demand curve is solved for P
P = 100 – 2Q
TR = PQ
TR = Q(100 – 2Q)
TR = 100Q – 2Q2
• MR
MR = dR = 100 – 4Q
dq
• MC
TC = 50 + 40Q MC = dTC = 40
dq
3. • Profit maximization output?
MR =MC
100 – 4Q = 40
Q =15
• What is the price at which profits are maximizing?
P = 100 – 2Q
P = 100 – 2* 15 = 70
• What is the total profit when profits are maximizing?
Profits = TR –TC = 1050 -650 = 400
