Answer to Problem 6E
OUTPUT(UNITS) | TOTAL COST($) | MARGINAL COST | AVERAGE COST |
10 | 110 | - | 11 |
15 | 150 | 40 | 10 |

30 | 300 | 75 | 10 |
35 | 385 | 85 | 11 |
40 | 480 | 95 | 12 |
Explanation of Solution
Given:
Assume that a firm in a
OUTPUT(UNITS) | TOTAL COST($) |
10 | 110 |
15 | 150 |
20 | 180 |
25 | 225 |
30 | 300 |
35 | 385 |
40 | 480 |
Explain:
Marginal cost defines that the extension to the total cost by cause of the increment in one unit of output. Average cost is per unit cost. Total cost is divided by the output to know the average cost.
The following is the marginal and average cost schedule:
OUTPUT(UNITS) | TOTAL COST($) | MARGINAL COST | AVERAGE COST |
10 | 110 | - | |
15 | 150 | ||
20 | 180 | ||
25 | 225 | ||
30 | 300 | ||
35 | 385 | ||
40 | 480 |
Above schedule depicts the output, total cost, marginal cost and average cost. Marginal cost and average costs schedule have been derived from the output and total cost schedule.
Introduction: Marginal cost defined as the production cost that includes all the costs will be vary within that level of the production. Suppose if the firm need to build the new firm to extend to produce the goods and services, the cost of the building firm is called as the marginal cost.
b)
To calculate: The total number of units will be produced and sold and find the profits per unit and total profits, if the prevailing market price is $17 per unit
b)
Answer to Problem 6E
The total number of units will be produced and sold is 35
The Profits per unit is
The total profit is
Explanation of Solution
Given:
Assume that a firm in a perfectly competitive industry has the following total cost schedule:
OUTPUT(UNITS) | TOTAL COST($) |
10 | 110 |
15 | 150 |
20 | 180 |
25 | 225 |
30 | 300 |
35 | 385 |
40 | 480 |
Let the prevailing market price is $17 per unit.
Explain:
Purely competitive market is characterized by the large number of buyers and sellers. Price is decided by the demand and supply forces. Price is equal to the marginal cost (P=MC).Thus, price and marginal costs are equal at the 35 units of output. A total of 35 units of output will be produced and sold.
Cost per unit is $11 and price per unit is $17.Thus, Profit per unit is
Introduction: Market price is one kind of current price in that the asset or service will be purchase or sale. In terms of economic theory, marginal cost defined as the point of forces of demand and supply meet.it is the prevailing price on the certain day or a certain time.
c)
To describe: The industry in long-run equilibrium at the given price.
c)
Answer to Problem 6E
Firm is not in long-run equilibrium and also firm gets only normal in long-run purely competitive market.
Explanation of Solution
Given:
Assume that a firm in a perfectly competitive industry has the following total cost schedule:
OUTPUT(UNITS) | TOTAL COST($) |
10 | 110 |
15 | 150 |
20 | 180 |
25 | 225 |
30 | 300 |
35 | 385 |
40 | 480 |
Explain:
Purely competitive market is characterized by the large number of buyers and sellers in the market. Price is decided by the demand and supply forces in the market. Firm earns the abnormal profit at this price and more firms would be attracted toward the market. Abnormal profit would be withered away. Now each firm would be earning normal profit.
Introduction: When long run equilibrium occur, that time the marginal revenue equals to the marginal costs to be also equal to the

- Suppose that the development of a new drought-resistant hybrid seed corn leads to a 50 percent increase in the average yield per acre without increasing the cost to the farmers who use the new technology. If the producers in the corn production industry were price takers, what would happen to the following? a. the price of corn b. the profitability of corn farmers who quickly adopt the new technology c. the profitability of corn farmers who are slow to adopt the new technology d. the price of soybeans, a substitute product for cornarrow_forwardThe wheat industry is comprised of many firms producing an identical product. Market demand and supply conditions are indicated in the left-hand panel of the figure attached; the long-run cost curves of a wheat farmer are shown in the right-hand panel. Currently, the market price for wheat is $2 per pound, and at that price, consumers are purchasing 800,000 pounds of wheat per day. Using the graphs attached, answer the following: a. How many pounds of wheat will each farmer produce if they want to maximize profits? b. How many farmers are currently serving the industry (fractional numbers are fine)? c. In the long run, what will the equilibrium price of wheat be? Briefly explain your answer.arrow_forwardAssume that the market determined price is $10 in a perfectly competitive industry. A firm is currently producing 100 units of output. Average total cost is $8 while marginal cost is $8 and average variable cost is $6. Is the firm producing the profit-maximizing level of output? Why or why not? If not, what should the firm do?arrow_forward
- Canadian red wheat is a normal good, in a perfectly competitive market that is in long-run equilibrium. There occurs a boom in the economy—incomes rise. What effect does this have on short-run equilibrium? Explain concisely the step-by-step process by which the industry returns to long-run equilibrium. Your answer should include the effects on the individual firm's output and profit, as well as any industry-wide adjustments that take place. Show graphically the relationship between the firm and the industry.arrow_forward(a) Let the industry producing soybeans be in a long-run equilibrium. What is the equilibrium price of a bushel of soybeans? How many billions of bushels are produced? How many farmers are there in the industry? What is the shipping fee per bushel of soybeans? (b) Suppose that the demand for soybeans drops due to decreased im- port by China and becomes Q = 15.3 − p. In a new long run equilibrium, what is the equilibrium price of a bushel of soybeans? How many billions of bushels are produced? How many farmers are there in the industry? What is the shipping fee per bushel? (c) Calculate the change in the producers’ surplus between the situations described in (a) and (b). (d) Show that the decrease in the producers’ surplus equals to the decrease in the total shipping fees as the industry contracts incrementally from the equilibrium output in (a) to the equilibrium output in (b).arrow_forwardA firm produces a product in a perfectly competitive industry and has a total cost function TC= 50+4q+2q². a. At the short-run market price of $20, the firm is producing 5 units of output. Is the firm maximizing its profit? Explain. b. What quantity of output will the firm produce in the long run, assuming there is no change in cost structure? What will be the long-run equilibrium price? c.
