A firm sells its product in a perfectly competitive market where other firms charge a price of $110 per unit. The firm estimates its total costs as C(Q) = 70 + 14Q + 2Q2. (LO3) b. What price should the firm charge in the short run? c. What are the firm’s short run profits? d. What adjustments should be anticipated in the long run?
Suppose that the pen-making industry is perfectly competitive. Also suppose that each current firm and any potential firms that might enter the industry all have identical cost curves, with minimum ATC = $1.25 per pen. If the market equilibrium price of pens is currently $1.50, what would you expect it to be in the long run? LO11.2 Â a. $0.25. b. $1.00. c. $1.25. d. $1.50.
Question 3 The current market price in a competitive industry is $15. Every firm in the industry operates a technology that implies costs described by the function C = 12.5 + 0.3Q2. In the future, the technology is expected to change, and the new cost function will then be C = 10 + 0.2Q2. How much profit is the typical firm making today and in the long run?
Â
O. Profit is zero both today and in the long run.
O. Profit is 125 both today and in the long run.
O. Profit is 175 today and zero in the long run.
O. Profit is 250 today and 125 in the long run.

- Suppose that each firm in a competitive industry has the following costs: Total cost: TC = 50 + q2 Marginal cost: MC = q where q is an individual firms quantity produced. The market demand curve for this product is Demand:QD = 120 P where P is the price and Q is the total quantity of the good. Currently, there are 9 firms in the market. a. What is each firms fixed cost? What is its variable cost? Give the equation for average total cost. b. Graph average-total-cost curve and the marginal-cost curve for q from 5 to 15. At what quantity is average-total-cost curve at its minimum? What is marginal cost and average total cost at that quantity? c Give the equation for each firms supply curve. d. Give the equation for the market supply curve for the short run in which the number of firms is fixed. e. What is the equilibrium price and quantity for this market in the short run? f. In this equilibrium, how much does each firm produce? Calculate each firms profit or loss. Is there incentive for firms to enter or exit? g. In the long run with free entry and exit, what is the equilibrium price and quantity in this market? h. In this long-run equilibrium, how much does each firm produce? How many firms are in the market?arrow_forwardA9 The characteristics of a "perfectly competitive" market require that there is 1) a large number of firms, 2) producing products that are identical across firms, 3) in an industry where there are no barriers to entry. It's unlikely that any industry accurately reflects these extreme assumptions, but what industries can you think of that do display these characteristics at least to some extent? Try to identify the limits of your example in reflecting "perfect" competition.arrow_forward6.a) Figure 8.7 shows cost curves for Penny's Parasols, a perfectly competitive firm.

The cost of the ingredients, the bottles, and the labels was $700. In addition, it took her 20 hours to make the ketchup and to do so she took time off from a job that paid her $20 per hour. Linda’s accounting profit is while her economic profit is.

His five acres of land show diminishingreturns because some are better suited for wheat productionthan others. The first acre can produce 1,000 bushels of wheat,the second acre 900, the third 800, and so on. Draw a table withmultiple columns to help you answer the following questions.How many bushels will each of the farmer’s five acres produce?How much revenue will each acre generate? What are the TR and MR for each acre? If the marginal cost of planting and har-vesting an acre is $7,000 per acre for each of the five acres, howm any acres should the farmer plant and harvest?  Note:- Don't use pen or paperarrow_forward
- . A firm in a perfectly competitive industry currently faces a market price of $20 and is maximizing    profit by producing 500 units of output at this price. The firm’s total costs are $14,000, of which     $5,000 are fixed costs.  a) How much profit is the firm making? (Show how you determine this.)  b) Should the firm continue to produce in the short run? Explain fully. c) Should the firm continue to produce in the long run? Explain clearly WHY the long run decision may    be different than the short run decision, assuming the firm expects no changes in demand conditions.arrow_forward12. If a competitive firm is currently producing a level of output at which profit is not maximized, then it must be true thata. marginal revenue exceeds marginal cost.b. marginal cost exceeds marginal revenue.c. total cost exceeds total revenue.d. None of the above is correct.arrow_forward2. Consider a firm that has no fixed costs and that is currently losing money. Are there any situations in which it would want to stay open for business in the short run?  3. Why is the equality of marginal revenue and marginal cost essential for profit maximization in all market structures? Explain why price can be substituted for marginal revenue in the MR = MC rule when an industry is purely competitive.arrow_forward
