Given the following: P = 20,000 - 15.6Q and TC= 400,000 +4640Q + 10Q2
where P is the product price, Q is the output level, and Q2 is Q squared
B. Assuming we have lost our patent but that the cost curves are the same AND we are in the long run, now find the price, output for the firm and output for the industry and firm profits for

Revenue = price X quantity = P X Q = (20000 - 15.6Q)Q = 20000Q - 15.6Q^2
MR = 20000 - 31.2Q
TC = 400000 +4640Q + 10Q^2
MC = 4640 + 20Q
Equating MR = MC gives 20000 - 31.2Q = 4640 + 20Q. This gives the monopoly output is Q = 300.
Monopoly price is P = 20000 - 15.6(300) = 15320
Profit = 15320 X 300 - 400000 - 4640(300) - 10(300)^2 = 1,904,000.
Now, we look at what happens with the perfect competition model:
In perfect competition, we know that 1) nobody earns economic profit and 2) price = marginal cost. Let's suppose that there are n sellers, each seller produces q units and the total ...
