Linda sells 100 bottles of homemade ketchup for $10 each. 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. LO9.1 a. $700; $400 b. $300; $100 c. $300; negative $100 d. $1,000; negative $1,100
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 a. $0.25. b. $1.00. c. $1.25. d. $1.50.
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.

- Modified True or False: State whether each statement is true or false. If the statement is false, briefly explain why it is so, and then restate it to make it true. The shapes of long-run cost curves follow directly from the assumption of a fixed factor of production, which implies diminishing returns. The optimal scale of plant is the scale of plant that maximizes average cost. In the long-run competitive equilibrium, each individual firm chooses a scale of operations that minimizes its long-run average cost. Answer correctly and explain within 30mins will give you positive feedback.arrow_forwardSuppose 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_forwardSuppose that you own a 10-acre plot of land that you would like to rent out to wheat farmers. For them, bringing in a harvest involves $30 per acre for seed, $80 per acre for fertilizer, and $70 per acre for equipment rentals and labor. With these inputs, the land will yield 40 bushels of wheat per acre. If the price at which wheat can be sold is $5 per bushel and if farmers want to earn a normal profit of $10 per acre, what is the most that any farmer would pay to rent your 10 acres? What if the price of wheat rose to $6 per bushel?arrow_forward
- Suppose that the paper clip industry is perfectly competitive. Also assume that the market price for paper clips is 2 cents per paper clip.

The same as the market demand curve for paper clips. d.

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? The total costs to produce four units is __________ while the average total cost to produce four units is _________.arrow_forward8. Why can the distinction between fixed costs and variable costs be made in the short run? Classify the following as fixed or variable costs: advertising expenditures, fuel, interest on company-issued bonds, shipping charges, payments for raw materials, real estate taxes, executive salaries, insurance premiums, wage payments, sales taxes, and rental payments on leased office machinery.

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_forwardCopy and complete the Table. iv.
