When the use of a communally owned resource has no price, then people will
use too much of this resource.
The satisfaction or happiness one gets from consuming a good or service is called
utility.

Suppose the price elasticity of supply for crude oil is 2.5. How much would price have to rise to increase the quantity supplied by 20%?
8%
Demand is said to be inelastic when
A reduction in price results in a decrease in total revenue
If actual production and consumption occur at Q1 and the price is P1
consumer surplus equals area a + b.
The intention of a price ceiling is to help consumers by forcing a price that is below the equilibrium price. What is one unintended consequence of this policy?
Consumers face a shortage of the good.
The difference between the maximum price a consumer is willing to pay for a product and the actual price the consumer pays is called
consumer surplus
For which graph is the supply perfectly inelastic?
Graph 3
Which of the following shows the combination of two products that have the same utility or satisfaction?
Indifference curve
Sam uses Craig's Netflix account to watch movies and shows but does not actually pay for the service himself. This is an example of
The free-rider problem
Which situation is consistent with the law of diminishing marginal utility?
The more pizza Joe eats, the less he enjoys an additional slice.
Why do private companies rarely provide public goods?
There is no way to force people to pay for the public good which increases free riders
Which of the following indifference curves is the most preferred?
U3
The governor has proposed to clean up all trash on the side of the highway. The project is estimated to cost the tax payers and additional $15,000. The city will benefit by having a clean highway which will entice tourists to stop along their routes. The project is estimated to bring in $18,000 of revenue from the highway being cleaned. Should the governor continue with the project?
Yes, the project will bring in $3,000 more in MB than MC.
The supply of product X is elastic if
a 5% increase in price generates a 7% increase in quantity supplied.
Jennifer buys a piece of costume jewelry for $33 for which she was willing to pay $42. The minimum acceptable price to the seller, Nathan, was $30. Jennifer experiences
a consumer surplus of $9 and Nathan experiences a producer surplus of $3.
If a price floor in this market is set at P2, then producer surplus equals area
b.
The equilibrium point in the market is the point at which the S and D curves intersect. At equilibrium, the producer surplus would be represented by the area
b.
Among the following examples, the one that best illustrates a public good is a(n)
bike path around a city or town.
Marginal utility is equal to
change in total utility divided by change in quantity consumed.
Total revenue decreases as the price of a good increases, if the demand for the good is
elastic
Which of the following is an example of a negative externality (additional social cost)?
falling property values in a neighborhood where a disreputable nightclub is operating
In deciding what to buy to maximize utility, the consumer should choose the good with the
highest marginal utility per dollar spent.
Assume that product Alpha is $2 per unit and product Beta is priced at $1 per unit and that Ellie has $20 to spend on Alpha and Beta. She buys 4 units of Alpha and 12 units of Beta. The marginal utilities of the last unit of Alpha and Beta that she purchases are 40 utils and 20 utils, respectively. This indicates that
in order to maximize utility, Ellie should buy more Beta and less Alpha.
If the absolute value of the price elasticity of demand for a good is .75, the demand for that good is described as
inelastic.
A negative income elasticity of demand indicates that the product
is an inferior good.
Deadweight losses occur when the quantity of an output produced is
less than or greater than the competitive equilibrium quantity.
When producers do not have to pay the full cost of producing a product, they tend to
overproduce the product because of a negative externality
The basic formula for the price elasticity of demand is
percentage change in quantity demanded/percentage change in price.
In which instance will total revenues decline?
price increases and Ed equals -2.47
If actual production and consumption occur at Q1 and the price is P2
producer surplus equals area c + b.
The amount of revenues that sellers actually receive over and above the minimum acceptable amount that they are willing to receive for selling a product is called
producer surplus.
The demand for a luxury good whose purchase would exhaust a big portion of one's income is
relatively elastic.
The table below shows the utility schedule for a consumer of candy bars. Candy Bars Consumed Total Utility 0 0 1 5 2 9 3 12 4 14 5 15 6 15 7 13 Marginal utility becomes negative with the consumption of the
seventh candy bar
The cross-price elasticity of demand between product X and product Y is 2. It can be inferred that X and Y are
substitutes.
The elasticity of demand for a product is likely to be greater
the greater the amount of time over which buyers adjust to a price change.
