Market demand is given by Q=1200-50P
Consider instead a monopoly market with only one firm. The firm’s marginal costs are given by MC=(1/150Q)+4.
Q=1200-50P
P= 24-0.02Q
TR= 24Q-0.02Q^2
MR= 24-0.04Q
MC= (Q/150)+(4)
a. Monopolist produces at MC =MR.
24-0.04Q=(Q/150)+4
Output Q*= 428.5≈ 429
Price P*= 24-0.02*429= 15.4≈ 15
b. Point A is the profit maximising level.
c. No, this is not an efficient outcome as efficient outcome is at P=MC but monopolist produces at MC =MR.
