Which of the following observations would be consistent with the imposition of a binding price ceiling on a market?

a smaller quantity of the good is bought and sold

A demand curve reflects each of the following except the

ability of buyer to obtain the quantity they desire.

In a competitive market, the quantity of a product produced and the price of the product are determined by

all buyers and sellers

When we move along a given demand curve

all non-price determinants of demand are held constant.

A supply curve slopes upward because

an increase in price gives producers an incentive to supply a larger quantity

Consumer surplus in a market can be represented by the

area below the demand curve and above the price

Lily purchases a 1967 Dodge for $3,000, planning to restore and sell the car. He restores the car for $9,000. He can sell the car for $10,000 at this point in time. As an alternative, he can spend an additional $3,000 replacing the engine. With a new engine the car would sell for $13,000. Lily should

be indifferent between (I) selling the car now and (II) replacing the engine and then selling it.

If a shortage exists in a market, then we know that the actual price is

below the equilibrium price, and quantity demanded is greater than quantity supplied.

Trade between the US and China

benefit both the US and China

A government-imposed price of $6 in this market could be an example of a

binding price ceiling and non-binding price floor.

A shortage results when a

binding price ceiling is imposed on a market

The price elasticity of demand measures

buyers' responsiveness to a change in the price of a good.

A binding price floor

causes a surplus and is set at a price above the equilibrium price

If the government levies a $500 tax per car on sellers of cars, then the price received by sellers of cars would

decrease by less than $500.

A tax on the sellers of coffee will increase the price of coffee paid by buyers

decrease the effective price of coffee received by sellers, and decrease the equilibrium quantity of coffee.

Suppose you are in charge of setting prices at a local ice cream shop. The business needs to increase its total revenue, and your job is on the line. You evaluate the data and determine that the price elasticity of demand for ice cream at your shop is 1.8. You should

decrease the price of ice cream.

If the government removes a binding price ceiling from a market, then the price paid by buyers will

decrease, and the quantity sold in the market will increase.

Total surplus is represented by the area below the

demand curve and above the supply curve, up to the equilibrium quantity.

Which of the following event must cause equilibrium price to fall?

demand decreases and supply increases

The producer that requires a smaller quantity of inputs to produce a certain amount of a good, relative to the quantities of inputs required by other producers to produce the same amount of that good,

has an absolute advantage in the production of that good.

A decrease in the price of a good will

increase in quantity demanded

If a good is normal, then an increase in income will result in a(n)

increase in the demand for the good.

If the government levies a $5 tax per ticket on buyers of NFL game tickets, then the price paid by buyers of NFL game tickets would

increased by less than $5

You love peanut butter. You hear on the news that 50 percent of the peanut crop in the South has been wiped out by drought and that this will cause the price of peanuts to double by the end of the year. As a result, your demand for peanut butter

increases today

Holding all other forces constant, if decreasing the price of good leads to a decrease in total revenue, then the demand for the good must be

inelastic

Consumer surplus

is measured using the demand curve for a product.

When demand is inelastic, the price elasticity of demand is

less than 1, and price and total revenue will move in the same direction.

A binding price ceiling is shown in

panel B only

When the price is P1, area C represents

producer surplus

A professor at CSULB spends 11 hours per day giving lectures and writing papers. For the professor, a graph that shows her various possible mixes of output (lectures given per day and papers written per day) is called her

production possibilities frontier

The price elasticity of demand measures how much

quantity demand responds to a change in price

Demand is said to be inelastic of the

quantity demanded change proportionately less than price.

A price elasticity of demand measures how much

quantity demanded responds to a change in price

Assume that Jamaica and Norway can switch between producing coolers and producing radios at a constant rate. The following table shows the number of coolers or number of radios each country can produce in one day. Jamaica has an absolute advantage in the production of

radios and Norway has an absolute advantage in the production of coolers.

When consumers face rising gasoline prices, they typically

reduce their quantity demanded more in the long run than in the short run.

The smaller the price elasticity of demand, the

smaller the responsiveness of quantity demanded to a change in price

If sellers expect higher basket prices in the near future, the current

supply of baskets will decrease

For a good that is a luxury, demand

tends to be elastic.

The production possibilities frontier shows

the combinations of outputs that an economy can produce.

A surplus exists in a market if

the current price is above its equilibrium price

Suppose that Juan Carlos is filling out a survey that he received in the mail. The survey asks him what he would do if the price of his favorite toothpaste increased. Juan Carlos reports that he would switch to a different brand. The survey asks what he would do if the price of all toothpastes increased. Juan Carlos reports that he must use toothpaste, so he would have to adjust his spending elsewhere. These examples illustrate the importance of

the definition of a market in determining the price elasticity of demand.

Suppose demand is perfectly inelastic, and the supply of the good in question decreases. As a result,

the equilibrium price increases, and the equilibrium quantity is unchanged.

If a price floor is not binding, then

the equilibrium price is above the price floor

"Other things equal, when the price of a good rises, the quantity demanded of the good falls, and when the price falls, the quantity demanded rises." This relationship between price and quantity demanded is referred to as

the law of demand

A university's football stadium is never more than half-full during football games. This indicates

the ticket price is above the equilibrium.

For a lot of students, the largest cost of going to a college is

the wages given up because of attending school.

When the price of a good or service changes,

there is a movement along a given demand curve

For every unit of the good that is sold, sellers are required to send

three dollars to the government, and buyers are required to send nothing to the government.

Another way to think of the marginal seller is the seller who

would leave the market first if the price were any lower.
