A change in quantity demanded is a change in the amount of a good demanded resulting solely from what?
A change in price
A change in demand is a change in the amount of a good demanded resulting from a change in what?

FALSE (along the supply curve)
The market equilibrium price and quantity is the point where the supply and demand curves intersect. This is also known as what?
Market clearing price
If the price is set below equilibrium price, what will result?
- Quantity demanded will exceed quantity supplied
- SHORTAGE
If the price is set above the equilibrium price, what will result?
- Quantity demanded will be less than quantity supplied
- SURPLUS
Give an example of a price floor.
Minimum wage
Give an example of a price ceiling
Rent control
Give an example of a price ceiling
Rent control
If the supply or demand curve shifts, what will be the impact on the equilibrium price and quantity?
It will change
What six factors shift the demand curve?
WRITEN
1) Change in WEALTH
2) Change in price or RELATED goods
3) Changes in consumer INCOME
4) Changes in consumer TASTES or preferences for a product
5) Changes in consumer EXPECTATIONS
6) Changes in # of buyers served by the market
If the price of computers fall, what will happen to the demand for peripherals?
Increase (complements)
As the price of computers fell, what happened to the demand for typewriters?
Decreased (substitutes)
What five factors shift the supply curve?
ECOST
1) Changes in price EXPECTATIONS of the supplying firm
2) Changes in production COSTS
3) Changes in the price or demand for OTHER goods
4) Changes in SUBSIDIES or taxes
5) Changes in product TECHNOLOGY
What is the effect on equilibrium Q and equilibrium P when there is an increase in both demand and supply?
- Equilibrium Q: Increase
- Equilibrium P: Indeterminate
What is the effect on equilibrium Q and equilibrium P when there is an increase in demand and a decrease in supply?
- Equilibrium Q: Indeterminate
- Equilibrium P: Increase
What is the effect on equilibrium Q and equilibrium P when there is a decrease in both demand and supply?
- Equilibrium Q: Decrease
- Equilibrium P: Indeterminate
What is the effect on equilibrium Q and equilibrium P when there is a decrease in demand and an increase in supply?
- Equilibrium Q: Indeterminate
- Equilibrium P: Decrease
What is a measure of how sensitive the demand for, or the supply of, a product is to a change in price?
Elasticity
How do you calculate the price elasticity of demand?
- Percentage change in QD divided by the percentage change in P
True or false.
In a normal demand curve, the price elasticity of demand is usually positive.
False (negative; reflects downward sloping demand curve)
Give an example of a relatively inelastic good.
Gasoline
If price inelasticity is zero, demand is perfectly inelastic. What does that mean?
Demand does not depend at all on price
If the price elasticity of demand for a good is > 1.0, what does that say about the demand for the good?
Elastic
What causes elasticity?
- Product demand is more elastic with more substitutes available, but inelastic if few subs are available
If the price elasticity of demand for a good = 1.0, what does that say about the demand for the good?
Unit elastic (percentage change in QD caused by a change in P equals the percentage change in P)
What are the effects of price inelasticity on total revenue?
Positive relationship
- Increase in price (proportionately smaller decrease in QD)
- Increase in total revenue
What are the effects of price elasticity on total revenue?
Negative relationship
- Increase in price (proportionately larger decrease in QD)
- Decrease in total revenue
What are the effects of unit elasticity on revenue?
No effect
How do you calculate the price elasticity of supply?
Percentage change in QS divided by percentage change in P
If the price elasticity of demand for a good is
Inelastic
If the good is price inelastic, what is the price elasticity of supply?
If the good is price elastic, what is the price elasticity of supply?
> 1.0
Supply is unit elastic if the absolute price elasticity of supply is equal to what?
1.0
What two factors affect price elasticity of supply?
1) Feasibility of producers storing the product
2) Time required to produce and supply the good
A product that can be produced and stored until needed may have a ____ elasticity of supply.
High
Perishables, such as flowers, cannot be stored for very long and may have a ____ elasticity because it is more difficult to increase supply when the prices rise.
Low
A longer production time leads to ____ price elasticity.
Lower
What does a perfectly inelastic supply curve reflect?
Reflects that QS is insensitive to price changes
What measures the percentage change in the QD (or QS) of one good caused by the price change of another good?
Cross elasticity of demand (or supply)
If the cross elasticity of demand/supply coefficient is positive, what does that say of the two goods?
Substitutes (if price of Product A goes up, demand for Product B goes up)
If the cross elasticity of demand/supply coefficient is negative, what does that say of the two goods?
Complements (increase in price of Product A results in decrease QD for Product B)
If the cross elasticity of demand/supply coefficient is zero, what does that say of the two goods?
Unrelated
What does the income elasticity of demand measure?
Percentage change in QD for a product for a given percentage change in income
How do you calculate the income elasticity of demand (or supply)?
= % change in # of units of X demanded
divided by % change in income
What do you call a product whose demand is positively related to income?
Normal good (as income goes up, demand for normal goods increases)
Positive income elasticity indicates what type of good?
Normal good
