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.

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.

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.

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

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

the ticket price is above the equilibrium.

there is a movement along a given demand curve

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.
