Firms in a particular industry each have total cost functions given by Q3 -6Q2+25Q+50.

If this is a competitive market ,what price is consistent with the long run equilibrium?

Homework Answers

Answer #1

In long run equilibrium there is no net profit, which means that the average total cost equals to the price. The total cost function is given. After some simple mathematics, we end up with price equals to 29.32 in order to be in long run equilibrium. The workings are shown below in the image.

Hope this helps. Do hit the thumbs up. Cheers!

A competitive industry currently consists of 50 identical firms. An individual firm’s total cost function is given by TC = 1⁄2 q2 + 450 and its marginal cost MC = q, where q is the quantity supplied by the firm. Market demand is given by Q = 4000 - 5P, where Q is the market quantity demanded and P is the market price. In the long run market equilibrium, how much will each firm produce?

Assume that a perfectly competitive, constant cost industry is in a long run equilibrium with 60 firms. Each firm is producing 90 units of output which it sells at the price of $41 per unit; out of this amount each firm is paying $3 tax per unit of the output. The government decides to decrease the tax, so the firms will be paying $1 tax per unit. a) Explain what would happen in the short run to the equilibrium price...

Assume a competitive industry is in long-run equilibrium and firms in the industry are earning normal profits. Now assume that production technology improves such that average total costs decline by $5 per unit. How will the industry move to a new long-run equilibrium? a. The fall in costs will result in economic profits and firms will enter the market causing the price to fall until all firms only have normal profits. b. The new long-run equilibrium will be where each...
