Marginal utility is the
Change in total utility obtained by consuming one extra unit of a good or service
The term market mechanism refers to
The use of market prices and sales to signal desired output
If public goods were marketed like private goods, then
There would be market failure
Complete Table 19.3 below. Assume the price of cola is $8 per unit and the price of pretzels is $4 per unit. Refer to Table 19.3. If Michael has $28 dollars to spend, why will three colas and four pretzels not be optimal?

This combination is not affordable
From an economic standpoint, government intervention is justified
When the market mechanism fails to achieve the optimal mix of output

Which of the following is consumed jointly?
A missile shield.
The law of diminishing marginal utility states that
As a consumer enjoys successive units of a good, eventually marginal utility will fall
Resources are directed from one industry to another by
Changes in market prices
The benefit that consumers get when they buy goods at the equilibrium price is called
Consumer surplus
In the market economy, producers will produce the goods and services that
Consumers demand
Which of the following is an example of a public good?
Flood control
Complete Table 19.3 below. Assume the price of cola is $8 per unit and the price of pretzels is $4 per unit. Refer to Table 19.3.

In Table 19.2, the marginal utility of the third unit is 6.
If an individual demands a good, it means that he or she
Is willing and able to purchase the good at some price
Which of the following explains why flood control is a public good?
It is not divisible and therefore cannot be kept from people who do not pay.
Assume Amanda always maximizes her total utility given her budget constraint. Every morning for breakfast she has two eggs and three sausages. If the marginal utility of the last egg is 10 utils and the price of the eggs is $1 each, what can we say about the marginal utility of the last sausage if the price of each sausage is $27
It must be equal to 20 utils
The market tends to underproduce public goods because
Joint consumption allows those who do not pay for the good to still benefit from the good
A consumer maximizes total utility from a given amount of income when the
Marginal utility obtained from the last dollar spent on each good is the same
Any imperfection in the market mechanism that prevents optimal outcomes is known as
Market failure
Governments usually build highways because it is difficult to exclude individuals who don't pay for the highways from using them. What type of market failure is involved?
Public goods
The optimal mix of output is the most desirable combination of output attainable with existing
Resources, technology, and social values
Which of the following is not a determinant of demand
The cost of the factor inputs
Which of the following produces external benefits?
The inoculation of college students against the flu
If the consumption of a good yields external benefits, then
The social demand is greater than the market demand
