Assume a firm with the following

Demand Curve: P = 10,004 – Q
Total Cost Curve: TC = 15,000,000 + 4Q + Q2

   •   What is the Profit-Maximizing Price and Quantity this firm will use? Show work
   •   Is the firm making a profit or a loss? Explain why
   •   Should the firm stay in business or quit immediately? Explain why

Expert Solution

P = 10004 - Q

TR = PQ

TR = (10004 - Q)Q

TR = 10004Q - Q²

dTR/dQ = MR = 10004 - 2Q

MR = 10004 - 2Q

TC = 15,000,000 + 4Q + Q²

dTC/dQ = 4 + 2Q

MC = 4 + 2Q

Profit maximising condition

MR = MC

10004 - 2Q = 4 + 2Q

10004 - 4 = 2Q + 2Q

10000 = 4Q

Q = 10000/4

Q = 2500

P = 10004 - Q

P = 10004 - 2500

P = 7504

Thus, profit maximising quantity is Q = 2500 and price is P = 7504

profit = PQ - TC

= PQ - 15,000,000 - 4Q - Q²

= 7504(2500) - 15,000,000 - 4(2500) - (2500)²

= 18,760,000 - 15,000,000 - 10,000 - 6,250,000

= 18,760,000 - 21,260,000

= - 2,500,000

Therefore the firm is making a loss of 2,500,000

TC = 15,000,000 + 4Q + Q²

TVC = 4Q + Q²

AVC = TVC/Q

AVC = (4Q + Q² )/Q

AVC = 4 + Q

At profit maximising quantity Q = 2500 average variale cost is

AVC = 4 + 2500

AVC = 2504

Since P > AVC which means the firm is able to cover all its variale costs and have some revenue left over for paying a proportion of its fixed costs.Hence the firm will continue or stay in business.

A monopolist has a demand curve given by P = 120 - Q and a total cost curve given by TC = 50 +2Q2. The associated marginal cost curve is MC = 4Q. Suppose the monopolist also has access to a foreign market in which he can sell whatever quantity he chooses at a constant price of 88. How much will he sell in the foreign market? What will his new quantity and price be in the original market?

Assume a consumer whose demand curve is given by p = 10 – q. There is an incumbent monopolist whose marginal cost is 2. What are the monopoly price, monopoly profit, and consumer surplus? Now suppose that there is a potential entrant whose marginal cost is zero. If there is entry, the incumbent firm and the entrant compete in prices for the homogenous product. If entry, what would be the market price and what would be consumer surplus? Can the...
