1. Organize factors of production and/or2. Produce goods and services and/or3. Sell produced goods and services
• A virtual firm organizes production and subcontracts out all work
• Many of the organizational structures of business are being separated from the
production process

The factory size can change
Long Run
Factors like labor and raw materials can be changed
Short Run:
laborraw materials
• Long run and short run do not necessarily refer to specific periods of time, but to the flexibility the firm has
in changing the level of output

The least cost combination of inputs.
Efficient Production
The recipe: going from inputs to outputs
It varies by firm

Like Labor
In the beginning, output increases with each unit added, but at some point output will begin to decrease
with each additional unit of a resource.
The Law of Diminishing Returns

She produces these in her own home without any help, unless she has a large number of orders on a
particular day.
Marcia Deal bakes and decorates large, elaborate,
multi-layered, special occasion cakes.

With the following information, complete the table:
The total cost of producing 5 cakes is $135Marcia’s total fixed cost for 1 cake is $25
The total cost of 2 cakes is $60
The total variable cost for 1 cake is $25
The total variable cost of producing 7 cakes is $220The marginal cost of the 6th cake is $45
The marginal cost for the 8th cake is $91The ATC per cake when 3 cakes or when 4 cakes are made is $25
Why is the Marginal Cost of the 7th and 8th cakes fairly high?
![Page 14: 1.Organize factors of production and/or 2.Produce goods and services and/or 3.Sell produced goods and services A virtual firm organizes production and.](https://reader035.fdocuments.in/reader035/viewer/2022062722/56649f295503460f94c42ac6/html5/thumbnails/14.jpg)
If Marcia can sell from 0 - 8 cakes at $40 each, how many will she choose to
produce and sell per day if she is trying to maximize her profits??
On the graph, plot the average total cost and marginal cost of producing
from 0 – 8 cakes.Plot the marginal cost at the
midpoints

• If MC > ATC, then ATC is rising
• If MC > AVC, then AVC is rising
• If MC < ATC, then ATC is falling
• If MC < AVC, then AVC is falling
• If MC = AVC and MC = ATC, then AVC and ATC are at their minimum points

1. Which of the following is most likely to be an implicit cost of production?
a. property taxes on a building owned by the firmb. transportation costs paid to a trucking supplierc. rental payments for a building utilized by the company and rented
from another partyd. interest income foregone on funds invested in the firm by the
owners
2. The law of diminishing returnsa. explains why marginal cost eventually increases as output expands.b. implies that average fixed cost will remain unchanged as output expands.c. is true for physical production activities but not for activities such as studying.d. applies to a capitalist economy but would be irrelevant if the means of production were owned by the state.
3. Which of the following represents a long-run adjustment?a. the hiring of four additional cashiers by a supermarketb. a cutback on purchases of coke and iron ore by a steel manufacturerc. construction of a new assembly-line plant by a car manufacturerd. the extra dose of fertilizer used by a farmer on his wheat crop

4. The short-run average total cost (ATC) curve of a firm is U-shaped becausea. larger firms always have lower per-unit costs than smaller firms.b. at low levels of output, AFC will be high, while at high levels of output, MC will be high as the result of diminishing returns.c. diminishing returns will be present when output is small, and high AFC will push per-unit cost to high levels when output is large.d. diseconomies of scale will be present at both small and large output rates.
5. When costs that vary with the level of output are divided by the output, you have calculated
a. total changing cost. b. total fixed cost.c. average fixed cost. d. average variable cost.
6. In the short run, if average variable cost equals $50, average total cost equals $75, and output equals 100, the total fixed cost must be a. $25. b. $2,500. c. $5,000. d.$7,500.
