The local newspaper has asked you (as a top economics student) to provide an industry analysis of hair stylists in Midtown. Here is what you've found so far:
1) There are 100 hair stylists in Midtown which all compete against one another for clients.
2) The market price for a hair styling is $20.
3) All firms in the market have a monthly overhead cost of $5,625 and a monthly variable cost that you've determined to be VC = $5q + $.01q2
The optimal amount of hair stylings given per month per firm is ___ and the monthly profits per firm are $___.
Bill runs a business that makes custom-printed towels. It will cost him $8 each to purchase and print on towels, and he will have to pay a rent of $1,700 per month for him workshop. Based on market research, Bill estimates that he can sell custom towels for $25 each.
a) Calculate the number of towels he needs to sell per month to break-even.

- Joe is the owner-operator of Joe's Haircuts Unlimited. Last year he earned $175,000 in total revenues and paid $110,000 to his employees and suppliers. During the course of the year, he received three offers to work for other barbers, with the highest offer being $60,000 per year. Is Joe earning a normal profit? No, he is earning an above-normal profit. No, but he is earning an accounting profit and that is all that matters. Yes, but his economic profit is $0 and that is not good. We cannot be sure, because "normal" profit is a subjective judgment. No, his economic profit is negative.arrow_forwardWhich of the costs discussed in the chapter is the most important when a firm is deciding how much to produce? Costs that are spent to improve the image of the firm. A firm will choose to increase output if it spends a large amount on advertising and brand image. Fixed costs because these costs are spent and cannot be changed in the time period under consideration. If fixed costs are higher, the firm will choose to produce more output. Variable costs because these costs change as output changes. If the firm wants to maximize profits, it will choose to produce a quantity where variable costs are minimized. Marginal cost because this cost shows the additional cost associated with producing one more unit of output. Firms will use this information to decide to produce more or less output.arrow_forwardQuestion content area Part 1 Charles Lackey operates a bakery in Idaho Falls, Idaho. Because of its excellent product and excellent location, demand has increased by 25% in the last year. On far too many occasions, customers have not been able to purchase the bread of their choice. Because of the size of the store, no new ovens can be added. At a staff meeting, one employee suggested ways to load the ovens differently so that more loaves of bread can be baked at one time. This new process will require that the ovens be loaded by hand, requiring additional manpower. This is the only thing to be changed. The bakery currently makes 1,800 loaves per month. The pay will be $ 8 per hour for employees and each employee works 160 hours per month. Charles Lackey can also improve the yield by purchasing a new blender. The new blender will mean an increase in his investment. This new blender will mean an increase in his costs of $ 100 per month, but he will achieve the same…arrow_forward
- The graph shows the demand (D), marginal cost (MC), marginal revenue (MR), and average variable cost (AVC) curves for a firm that is a price maker for its product. The MC and AVC curves slope upward because of limited space and resources for production activity: To increase output, the firm must bring older, less-reliable equipment out of storage, pay its workers extra for overtime hours, and so on. If the firm is able to practice price discrimination, using the two prices indicated by the two points indicated on the demand curve, use the area tool to outline the region that represents the net revenue (revenue minus production costs, but ignoring fixed costs). The lower boundary of the region should be slanted. To refer to the graphing tutorial for this question type, please click here.

The market for wheat is perfectly competitive and the current market price for wheat is $10 per bushel. Dena is currently producing 8 bushels (Dena can only produce this good in whole units). Her total cost at 8 units of output is $88 and her variable cost at 8 units of output is $64. Dena knows that if she produces a 9th unit her total cost will become $97, and if she produces a 10th unit her total cost will become $110. Dena’s goal is to maximize her profits. Based on this information, identify whether each of the following would be true or false and briefly explain your reasoning. Dena is currently losing money in the short-run and she would be better off if she shutdown and produced zero. Dena is not currently profit maximizing at 8 units of output and she could increase her profits if she expanded output by one unit. Dena would increase her…arrow_forward

If you arrive at 7:30 in the evening, you have at least an hour wait. Notwithstanding that fact, a few people arrive, speak quietly with the waiter/waitress, hand him some money, and are promptly seated. At some restaurants that do take reservations, there is a month-long wait for a Saturday evening, three weeks for a Friday evening, two weeks for Tuesday through Thursday, and virtually no wait for Sunday or Monday evening. How do you explain these events using demand and supply?arrow_forwardYour niece is deciding whether or not to open a lemonade stand. She expects to sell 20 cups of lemonade for $1 per cup.

- Determine the quantity of output that generates the maximum profit. Use the green points (triangle symbol) to indicate the amount of profit at this quantity of output. Then, determine the quantity of output that generates the maximum total revenue. Use the purple points (diamond symbol) to indicate the amount of revenue at this quantity of output. Note: Plot your points in the order in which you would like them connected. Line segments will connect the points automatically.

Its exports of milk to China increased by 45 % in 2013. More than 300 000 hectares land in New Zealand have been transferred to dairy use from other forms of farming and forestry use since 2000. The increase in milk production has caused the average cost of its production to fall and changes in production methods have affected the price elasticity of supply of milk . Discuss whether the average cost of production always decreases when a firm increases the total output that it produces(Define economies of scale and diseconomies of scale Use of graph to explain ( if applicable ) Explain the various economies of scale e.g. purchasing economies of scale [ up to 5 ] Explain the various diseconomies of scale [ up to Brief conclusion)arrow_forward
