Front 1

Marginal cost may be defined as:

a.) the change in average total cost which results from producing one more unit of output
b.) the change in average variable cost which results from producing one more unit of output
c.) the change in the total cost which results from producing one more unit of output
d.) the rate of change in total fixed cost which results from producing one more unit of output

Back 1

c.) the change in the total cost which results from producing one more unit of output

Front 2

Back 2

b.) total variable cost

Front 3

b.) variable costs tend to be greater than fixed csts
c.) all costs are fixed costs
d.) all costs are variable costs

Back 3

d.) all costs are variable costs

Front 4

If the government imposed a per-uinit or excise tax of 20 cents upon a product and the market price of the product rose by the full amount of the tax, it can be concluded that:

a.) producers will bear the entire burden of the excise tax
b.) consumers and producers wll share equally the burden of the excise tax.
c.) consumers will bear the entire burden of the excise tax
d.) not enough information has been given to determine how much of the burden is borne by consumers and producers

Back 4

c.) consumers will bear the entire burden of the excise tax

Front 5

Assume that you are the owner and only employee of a company that writes computer software that is used by gamblers to collect sports data. Last year you earned a total revenue of $90k. Your costs for quip., rent, and supplies were $60k. To start the business you quit a job at another computer software firm that paid $40k/yr. During this year your economic costs were:

a.) 40k
b.) 60k
c.) 100k
d.) 130k

Back 5

c.) 100k

Front 6

The demand for a good tends to be more price sensitive:

a.) the greater the availability of close substitutes
b.) the narrowers the definition of the market
c.) the longer the period of time
d.) all of the above are correct
e.) none of the above are correct

Back 6

d.) all of the above are correct

Front 7

Suppose that Adam Smith is currently buying a quantity of cereal and pop tarts at which the marginal utility per dollar's worth of cereal is greater than the marginal utility per dollar's worth of pop tarts. In order to maximize his total utility, he should:

a.) reduce his cereal consumption, thus raising it's MU/Pc to the level where MU/Pc = Mu/Ppt.
b.) increase his pop tart consumption, thus rainsing its MU/Ppt to the level where MU/Pc = MU/Ppt.
c.) reduce his pop tar consumption, thus lowering its MU/Ppt to the level where MU/Pc = NU/Ppt.
d.) increase his cereal consumption, thus lowering its MU/Pc to the level where Mu/Pc = MU/Ppt.

Back 7

d.) increase his cereal consumption, thus lowering its MU/Pc to the level where Mu/Pc = MU/Ppt.

Front 8

Which of the following costs keep getting smaller as the level of output increases?

a.) Marginal cost
b.) Total Fixed cost
c.) Average fixed cost
d.) Average variable cost

Back 8

c.) Average fixed cost

Front 9

A consumer buys only food and clothing. If the quantity of food bought increases while that of clothing remains the same, the marginal utiltiy of food will:

a.) fall, but not as fast as the marginal utiltiy of clothing falls
b.) rise, but not as fast as the marginal utility of clothing rises
c.) rise relative to the marginal utility of clothing
d.) fall relative to the marginal utility of clothing

Back 9

d.) fall relative to the marginal utility of clothing

Front 10

a.) high, low
b.) low, low
c.) high, high
d.) low, high
e.) marginal, inequitable

Back 10

b.) low, low

Front 11

When marginal cost is less than average cost:

b.) marginal cost must be falling
c.) marignal cost must be rising
d.) marginal cost may be rising, falling, or at it's minimum

Back 11

d.) marginal cost may be rising, falling, or at it's minimum
