Pure competition in the long run and short run.
Explanation of Solution
During a short run, the industry will have a precise number of companies. All of these will have a plant size that is set and is not in a position to be altered as it is there for a short run. Firms might shut down given the impression that it won't be making commodities during the short run, but they will not have adequate time to pay off its due obligations and their business will eventually close down.
In contrast, the industry, during the long run will have companies that are already in it and have ample time to either expand or minimize their size. Also, the company numbers in the industry can go up or come down as new companies enter or already present firms leave.
Concept Introduction:
Pure Competition: In pure competition, the number of buyers and sellers are large. They are selling homogenous products. Price is fixed by the market force. An individual producer or consumer cannot influence the price. There is no restriction for entry or exit, in the business. Consumers and producers are well aware of the market situation.

- 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_forwardQuestion 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.arrow_forwardAn economist estimated that the cost function of a single-product firm isC(Q) = 100 + 20Q + 15 Q^2+ 10 Q^3Based on this information, determine: (LO4, LO5)a.

- A9 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_forwardSuppose you are a perfectly competitive firm producing computer memory chips. Your production capacityis 1000 units per year. Your marginal cost is $10 per chip up to capacity. You have a fixed cost of $10,000 ifproduction is positive and $0 if you shut down. What are your profit-maximizing levels of production andprofit if the market price is ( a ) $5 per chip, ( b ) $15 per chip, and ( c ) $25 per chip? For case ( b ), explainwhy production is positive even though profits are negative?arrow_forwardQuantity Price Total Fixed Costs Variale Cost Total Costs Average Variable Costs Average Total Cost Marginal Cost Total Revenue Marginal Revenue 0 35 25 0 Â Â Â Â Â Â 1 35 25 20 Â Â Â Â Â Â 2 35 25 25 Â Â Â Â Â Â 3 35 25 35 Â Â Â Â Â Â 4 35 25 52 Â Â Â Â Â Â 5 35 25 80 Â Â Â Â Â Â If this firm produces a quantity of zero units, what is the total profits? What is the firm's marginal cost at a production level of two units? What is the average variable cost at a production level of five units? This firm becomes profitable producing at a quantity of ___ units. The average total cost is smallest at which level of production? At what quantity should this firm produce to maximize their profits based on your calculations?

Assume now that the costs of shipping are so large that Australian consumers can buy hand sanitizers from only one designated seller in Australia through both eBay and Amazon and there is no possibility of buying hand sanitizers in person in retail stores or any other online platforms. Explain with the help of a diagram whether this seller would be making a profit or a loss in the short run and in the long-run. Since it is one designated seller selling on two online market platforms (eBay and Amazon) would this be a monopoly or duopoly?arrow_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_forward
