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 a firm operating in a perfectly competitive industry has costs in the short run given by: SRTC = 8 + ½q2 and therefore MC = q. Assuming that the firm is a price-taker operating in a competitive market, derive an expression for the firm’s supply curve, (the profit maximizing output for the firm as a function of the market price, i.e., q S = f(p). Assuming the firm is one of 100 identical firms in the industry, what is the short-run supply curve for the industry, i.e., Q S = f(p)? If demand is given by Q D = 1000 – 100p, what are the short-run equilibrium price, market quantity, and firm quantity? Is this a long-run equilibrium? [Hint: Calculate firm profit in the equilibrium.]

Assuming that the firm is a price-taker operating in a competitive market, derive an expression for the firm’s supply curve, (the profit maximizing output for the firm as a function of the market price, i.e., q^s = f(p).

Consider a competitive industry with a market demand curve of P = 120 - 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 = 144 + q^2, where q is output of the individual firm. The short-run industry supply curve Qs is?
Which of the following is TRUE in long-run competitive equilibrium ("market saturation")? Group of answer choices Firms earn zero economic profit Price is equal to minimum average total cost All of the above are true Firms in the market earn just enough revenue to cover their explicit (accounting) costs and opportunity costs. None of the above are true New firms have no incentive to enter the market
Short-run supply and long-run equilibrium Consider the competitive market for titanium. Assume that, regardless of how many firms are in the industry, every firm in the industry is identical and faces the marginal cost (MC), average total cost (ATC), and average variable cost (AVC) curves shown on the following graph.

Assume a competitive industry is initially at its long-run equilibrium, given the inverse market demand and supply functions: P = 25000 − 0.2Qd and P = 5000 + 0.3Qs If all current firms in this market have identical cost structures and produce 50 units at their break-even point: Now, assume that the inverse demand for this product increases to P = 35000 − 0.2Qd, which leads to an entry of and additional number of firms whose cost structures are also identical to those who existed in the market before the increase in the demand. If the new long-run equilibrium price after both changes is 20000 cents: a- How many new firms entered this market? b- What is the value of the elasticity of supply at long-run market equilibrium? c- Draw a fully-labeled graph that demonstrated the above changes at the firm and market levels, highlighting the long-run industry supply curve

Find an individual firm’s supply curve. How many firms are there currently in the market? Find the equilibrium price and equilibrium market quantity. How much is output supplied by each firm, and how much profit does each firm make in the short run? Would you expect to see entry into or exit from the industry in the long run? Explain. What effect will entry or exit have on the market equilibrium? Find the long-run equilibrium price, the number of firms, and the amount of output each firm produces in the long run.

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?
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!
There is a competitive industry with an infinite number of potential firms. All firms have the same cost function c( q) = q^2 + 4. Industry demand is Q = 100 − 5p, where Q is total industry output and p is the output price. Let n denote the number of firms in the industry. Find the long-run equilibrium number of firms (n), price and quantity produced by each firm.
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.
