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?
Return to Figure 7.7. What is the marginal gain in output from increasing the number of batters from 4 to 5 and from 5 to 6? Does it continue the pattern of diminishing marginal returns? Figure 7.7 How output Affects Total costs
Based on your answers to the WipeOut Ski Company in Exercise 7.3, now imagine a situation where the firm produces a quantity of 5 units that it sells for a price of 25 each. What will be the companys profits or losses? How can you tell at a glance whether the company is making or losing money at this price by looking at average cost? At the given quantity and price, is the marginal unit produced adding to profits?
A computer company produces affordable, easy-to-use home computer systems and has fixed costs of 250. The marginal cost of producing computers is 700 for the first computer, 250 for the second, 300 for the third, 350 for the fourth, 430 for the fifth, 450 for the sixth, and 500 for the seventh. Create a table that shows the companys output, total cost, marginal cost, average cost, variable cost, and average variable cost. At what price is the zero-profit point? At what price is the shutdown point? If the company sells the computers for 500, is it making a profit or a loss? How big is the profit or loss? Sketch a graph with AC, MC, and AVG curves to illustrate your answer and show the profit or loss. If the firm sells the computers for 300, is it making a profit or a loss? How big is the profit or loss? Sketch a graph with AC, MC, and AVG curves to illustrate your answer and show the profit or loss.
Would you rather have efficiency or variety? That is, one opportunity cost of the variety of products we have is that each product costs more per unit than if there were only one kind of product of a given type, like shoes. Perhaps a better question is, What is the right amount of variety? Can there be too many varieties of shoes, for example?
Automobile manufacturing is an industry subject to significant economies of scale. Suppose there are four domestic auto manufacturers, but the demand for domestic autos is no more than 2.5 times the quantity produced at the bottom of the long-run average cost curve. What do you expect will happen to the domestic auto industry in the long run?
How would an improvement in technology, like the high-efficiency gas turbines or Pirelli tire plant, affect me lung-nm average cost curve of a firm? Can you draw the old curve and the new one on the same axes? How might such an improvement affect other firms in the industry?
Suppose that each firm in a competitive pizza market has the following identical cost: Total cost: TC=25+1.5Q2 i. Formulate the equation or level of fixed cost, variable cost, marginal cost, average variable cost (AVC) and average total cost (ATC) for each firm. ii. Sketch a diagram to illustrate average total cost (ATC) and marginal cost (MC) for Q from 1 to 20. Identify the quantity at which the average total cost (ATC) reaches its minimum and interpret its economic or business implication. iii.

Adoption of this innovation will help to reduce 20% of the variable cost for any given level of production while all other factors remain the same. A firm needs to pay a fee of $5 to adopt the innovation. Formulate the new production cost functions (TC, TFC, TVC, ATC and MC) for each firm.
Answer the following: 1. Assuming that the product’s price is P58 per pack, should the competitor sell in the short-runWhy or why not?If it decides to sell, what will be the profit-maximizing (or loss-minimizing output per day)?What is the profit (or loss) that the seller can realize per day? What is the profit (or loss) per pack?A. Assuming that the product price is P42 per pack, answer the same questions in letter A.B. Because of increasing sellers of masks in the market, the product’s price further decreased to P32per pack. Again, answer the same questions in letter A.C. When is this seller going to shut down?D. Now generate the seller’s supply curve of mask in the short run.

1. If the marginal product of an input is falling, then what must be true? Average fixed costs must be constant. Marginal cost must be rising. Average total cost must be constant. Marginal cost must be constant. 2. If Captain America and Thor decide to specialize, who should specialize in each good? Captain America should specialize in shields. Thor should specialize in hammers. Thor should specialize in both goods. Captain America should specialize in both goods. Captain America should specialize in hammers. Thor should specialize in shields. 3. Aditya regularly consumes two goods, which we’ll call good X and good Y. One day, the price of good X decreases. As a result, Aditya decreases his consumption of good Y. Based only on this information, goods X and Y seem to be: Substitutes for each other Complements for each other Normal goods Inferior goods
