. You know two things: 1) you are a single-price monopolist; and 2) demand is characterized by P(Q)=200-Q/1000. Your pricing manager suggests setting P=$75. True/False/Uncertain: You should fire your pricing manager. Explain why.
True, you should fire your manager.
--------
P=$75
P=200-Q/1000
75=200-Q/1000
125=Q/1000
Q=125000
The total revenue is
TR=P*Q=200Q-(Q^2)/1000
MR is the change in total revenue and found by differentiation
MR=dTR/dQ=200-Q/500
MR=200-Q/500
Q=125000
MR=-50
the MR is negative at the price manager adviced.
A monopoly produces at MR=MC where MC cannot be negative.
It means the firm should charge a price where MR is nonnegative, but here the MR is negative which means the price is not maximizing price and need to decrease output up to MR=MC.
