Suppose Amy gives haircuts on Saturdays to make extra money. She is the only person in town cutting hair on Saturdays and therefore has some market power. Assume that she does not incur fixed costs, and the only significant variable cost to Amy is her time. As she gives more haircuts, Amy must increasingly forgo other valuable Saturday activities. For example, if she gives one haircut, she forgoes reading the paper after breakfast. If she gives two haircuts, she gives up reading the paper and sleeping an extra half-hour. Amy's clients are a varied group willing to pay between $20.00 and $36.00 for a haircut. Assume that Amy cannot price discriminate, i.e., charge different clients different prices. If Amy charges $36.00 per haircut, she will have one client per week; if she charges $32.00, she will have two; if she charges $28.00, three, and so forth. The following table contains data on the revenues and costs of Amy's haircut business as a function of her price–quantity choice. (The costs are based on the value of Amy's alternative activities, in dollar terms. For example, the total cost of the first haircut is $4—the value Amy places on reading the newspaper after breakfast.) Fill in the missing cells of the table and then use them to answer the questions that follow. Output Price Total Revenue Marginal Revenue Total Cost Marginal Cost Profit (Haircuts per week) (Dollars per haircut) (Dollars per week) (Dollars per haircut) (Dollars per week) (Dollars per haircut) (Dollars per week) 0   0   0   0 36.00 4.00 1 36.00 36.00 4.00 32.00 28.00 4.00 2 32.00 64.00 8.00 56.00 20.00 8.00 3 28.00 84.00 16.00 68.00     4 24.00   24.00   4.00 8.00 5 20.00 100.00 32.00 68.00       On the following graph, use the blue points (circle symbol) to plot Amy's total revenue curve, use the orange points (square symbol) to plot her total cost curve, and use the purple points (diamond symbol) to plot her profit curve.

Suppose Amy gives haircuts on Saturdays to make extra money. She is the only person in town cutting hair on Saturdays and therefore has some market power.

For example, if she gives one haircut, she forgoes reading the paper after breakfast. If she gives two haircuts, she gives up reading the paper and sleeping an extra half-hour.
Amy's clients are a varied group willing to pay between $20.00 and $36.00 for a haircut. Assume that Amy cannot price discriminate, i.e., charge different clients different prices.

2. Marginal analysis and profit maximization
Suppose Amy gives haircuts on Saturdays to make extra money. She is the only person in town cutting hair on Saturdays and therefore has some
market power. Assume that she does not incur fixed costs, and the only significant variable cost to Amy is her time. As she gives more haircuts, Amy
must increasingly forgo other valuable Saturday activities. For example, if she gives one haircut, she forgoes reading the paper after breakfast. If she
gives two haircuts, she gives up reading the paper and sleeping an extra half-hour.
Amy's clients are a varied group willing to pay between $20.00 and $36.00 for a haircut. Assume that Amy cannot price discriminate, i.e., charge
different clients different prices. If Amy charges $36.00 per haircut, she will have one client per week; if she charges $32.00, she will have two; if she
charges $28.00, three, and so forth. The following table contains data on the revenues and costs of Amy's haircut business as a function of her price-
quantity choice. (The costs are based on the value of Amy's alternative activities, in dollar terms. For example, the total cost of the first haircut is $4-
the value Amy places on reading the newspaper after breakfast.)

Expert Solution
Step 1

Profit maximization is a short-run or long-run process of a firm to determine output, input, and price levels. The profit is maximum when the gap between total revenue and cost is at its maximum.
