Suppose you are given the following information about a particular industry Q(d) = 6500 - 100P Market Demand Q(s) = 1200P Market Supply C(q) = 722 + q^2/200 Firm total cost function MC(q) = 2q/200 Firm marginal cost function Assume that all firms in this industry are identical and that the market is characterized as perfect competition. Find the equilibrium price, the equilibrium quantity, the output supplied by the firm, and the profit of each firm. Would you expect to see entry into or exit from the industry in the long run? What effect would this entry or exit have on market equilibrium? What is the lowest price at which each firm would stay and sell its output in the long run? Is profit positive, negative or zero at this price? What is the lowest price at which each firm would sell its output in the short run? Is profit positive, negative, or zero at this price?
In a competitive market, the long-run demand is given by P = 20 - (0.01)*q Firms in the industry have as their cost structure the expression C = q3 - 5q2 + 10q. Determine: (a) equilibrium price b) Quantity produced-sold of the firm. c) What quantity is traded in the market? d) Over what time period does this market work? (short or long term?) e) What is the profit of the individual firm? f) What will be the behavior of the individual firm, will it exit or stay in the market?
The market for calculators is a perfectly competitive industry facing typical U-shaped ATC, AVC, and MC cost curves. Demand is linear and has a downward slope. The industry is filled with many homogeneous firms. Using a side-by-side graph that depicts both the market (on the left) and a representative firm (on the right), graphically depict what will happen to (a) P (price), (b) Q (market output), (c) q (representative firm's output), and (d) π (representative firm's profit) when the market moves from the original short run equilibrium (SRE) with positive profits to a new long run equilibrium (LRE).
Consider a competitive industry with a market demand curve of P = 252 – Q, where P is market price and Q is the quantity demanded in the market. Each firm in the industry has a cost function of TC = 196 + q2, if q > 0 where q is output of the individual firm (TC = 0 if q = 0). The market is initially in long-run equilibrium. The government decides to regulate the industry by issuing licences to all firms currently in the industry, and not to allow any further entry by other firms without a licence. That is, the number of licences is fixed, and entry requires that an existing licence holder sells their licence to the potential entrant, leaving the number of firms producing in the industry fixed. Subsequent to the introduction of this regulation, the market demand curve shifts to P = 432 – Q. What is the value of the licence?
Suppose Firm X is a dominant firm in a market where the market demand is Q = 1200 -2p. Once Firm X sets its price, those small competitors set their prices a little lower so that they can always sell up to their capacity. Assume the small firms’ combined capacity is 100 units. Further assume Firm X’s marginal cost is 50. Answer the following questions. Let Q^D be the quantity produced by the dominant firm. Write down the residual demand function faced by Firm X. (Hint: Think about how Q and Q^D are related.) Find Firm X’s profit-maximizing price.
Industry X has a market demand curve given by the equation P = 100 – Q/100, where P is the market price, and Q is industry-wide output.100 perfectly competitive firms currently operate in industry X. Each of these firms has a total cost function given by TC = 100 + 10q + q2, where q is the output of the individual firm, and thus MC = 10 + 2q. (a) Would any of the firms in industry X ever shut down in the short run? If so, what is the cut-off price required for firms to operate – Shut-down price? (b) What is the market output in the short run? What is the market price? How much do individual firms produce? Do firms earn economic profits? [Hint: you will first need to work out the industry supply curve.] *Note: when finding answers for this question online, they wrote to first find the AVC function for part a but I don't understand how they found that AVC function first- any help would be much appreciated!
Consider a competitive industry with a market demand curve of P = 252 - Q, where P is market price and Q is the quantity demanded in the market.

Consider a competitive industry with a market demand curve of P = 121 – Q, where P is market price and Q is the quantity demanded in the market. In the short run there are 4 firms in the industry, and each firm has a total cost function of TC = 25 + 6q + q2, where q is output of the individual firm.
