Market:

A group of buyers and sellers of a particular good or service.

Competitive Market:

Market with many buyers and many sellers.

Characteristics of a perfectly competitive market

1) Same good (cannot tell the difference between sellers)
2) So many buyers and sellers that none can influence the market price.
3) Not all goods are sold

Why are buyers and sellers "price takers"?

They must accept the market price as given.

Non perfect competitive markets:

1) Monopoly
2)Oligopoly
3)Monopolistic competition

Monopoly:

A market with only one seller (electricity)

Oligopoly:

A market with only few sellers ( car manufacturers)

Monopolistic Competition:

a market with a large number of sellers ( toothpaste manufacturers)

Quantity Demanded:

The amount of a good that buyers are willing and able to purchase.
-determined by price
-negatively related to price-- demand curve is downward sloping

Law of Demand:

other things equal, the quantity demanded of a good falls when the price of the good rises.

Demand Schedule:

A table with price of a good and the quantity demanded.

Demand Curve:

A graph of the relationship between the price of a good and the quantity demanded.

Market Demand:

the sum of all all of the individual demands.

Any factors other than price change- demand curve shifts

An increase in demand- shift to the right
A decrease in demand- shift to the left

Normal Good:

An increase in income-- increase in demand

Inferior Good:

an increase in income---- decrease in demand

Substitutes:

Increase in the price of one good-- increase in the demand for the other good

Complements:

Increase in the price of one good -- decrease in the demand for the other good

Tastes:

ex. General Surgeon Recommendations... cigarettes and cancer

Expectations:

Future Income: ex. higher future income increase current demand

Future Prices: ex. higher future prices increase current demand

Number of buyers:

more buyers-- higher demand

T/F: If the demand for a good falls when income falls, the good is called an inferior good.

False

T/F: When an increase in the price of one good lowers the demand for another good, the two goods are called complements.

True

T/F: Baseballs and baseball bats are substitute goods.

True

T/F: An increase in the price of pizza will shift the demand curve for pizza to the left.

True demand down = shift to left

T/F: Whenever a determinant of demand other than price changes, the demand curve shifts.

True

T/F: A reduction in the price of a product and an increase in the number of buyers in the market affect the demand curve in the same general way.

...

The Supply Curve:

The relationship between price and quantity supplied

Quantity Supplied:

the amount of a good that sellers are willing and able to sell.

-always positively related to price.

Law of Supply:

other things equal, the quantity supplied of a good rises when the price of the good rises

Supply Schedule:

a table with price of a good and the quantity supplied

Supply Curve:

a graph of the relationship between the price of a good and the quantity supplied

change in quantity supplied- movement along the supply curve

T/F: The quantity supplied of a good or service is the amount that sellers are willing and able to sell at a particular price.

True

T/F: The law of supply states that other things equal , when the price of a good rises, the quantity supplied of the good falls.

False

When any factors other than price change, the supply curve will shift.

increase in supply-- shift of the supply curve to the right
decrease in supply-- shift of the supply curve to the left.

Input prices:

higher, the supply decreases ( higher cost)

Technology:

Higher productivity, supply increases(lower cost)

Expectations:

higher future prices--- lower supply

Number of sellers

more sellers--- higher supply

T/F: If a company making frozen orange juice expects the price of their product to be higher next month, they will supply more to the market this month.

False

T/F: A supply curve slopes upward because, all else equal, a higher price mean a greater quantity supplied.

True

T/F: a movement along the supply curve is called a change in supply while a shift of the curve is called a change in quantity supplied.

False
-movement along supply curve- change in quantity supplied
-shift of the curve- change in supply

T/F: If there is an improvement in the technology of producing a product. the supply curve for the product will shift to the left.

False

The supply will increase and therefore shift to the left.

T/F: a reduction on an input price will cause a change in the quantity supplied, but not a change in supply.

False
supply will increase

Market's Equilibrium:

the point where the supply and demand curves intersect

Equilibrium:

when at certain price quantity supplied equals quantity demanded.

Equilibrium price:

the price that balances quantity supplied and quantity demanded

Equilibrium quantity:

the quantity supplied and the quantity demanded at the equilibrium price.

Surplus:

-quantity supplied is greater than quantity demanded
-if actual market price is higher than the equilibrium price

to lower surplus: producers lower the price (sales)

Shortage:

-quantity demanded is greater than quantity supplied
-if the actual price is lower than the equilibrium price

-sellers raise the price until the market reaches equilibrium

Law of supply and demand:

the price adjusts to bring the supply and demand into balance (equilibrium)

T/F: Quantity demanded is equal to quantity supplied, at the equilibrium price

True

T/F: Surpluses drive up the price while shortages drive down price:

False
Opposite

T/F: A shortage will occur at any price below the equilibrium price and a surplus will occur at any price above the equilibrium price.

True

Three Steps to Analyze Changes in the Equilibrium

-event shifts supply or demand(or maybe both)
-which direction the curves shift
-use the supply and demand diagram to see the changes

When an increase in the price of one good lowers the demand for another good the two goods are called complements a true b false?

When an increase in the price of one good lowers the demand for another good, the two goods are called compliments. True.

What if two goods are complements?

If two goods are complements, this means that a rise in the price of one commodity will induce a downward shift in demand for the other commodity. The prices of complementary or substitute goods also shift the demand curve.

What happens when a price increases for complementary good?

Complementary goods will have a negative cross elasticity of demand. If the price of one good increases, demand for both complementary goods will fall.

What are complementary and supplementary goods?

Supplementary Goods or Complementary Goods are goods that are used together. E.g. shoes and socks, knife and cutting board,… Remember, complementary sounds like complete, so in a sense, the products will complete each other (it would make more sense if they go together).
