Macroeconomics

Concerned with the overall ups and downs of the economy (large scale)

Household

A person or group of people that share their income

Firm

Any organization that produces goods or services for sale

PPC (The Production Possibility Curve)

Illustrates the necessary trade-offs in an economy that produces only two goods

Ceteris Paribus "Other things equal"

All other relevant factors remain unchanged

Efficient

There are no missed opportunities - there is no way to make some people better off without making other people worse off

Economic growth

An increase in the maximum amount of goods and services an economy can produce

Trade

Providing goods and services to other and receive goods and services in return

Specialization

When each person focuses on the task that they are good at performing

Comparative Advantage

Having the lowest opportunity cost among the people or countries that can produce that good or service

Absolute Advantage

Being able to produce more of a good or service with the given amount of time and resources

Terms of Trade

The rate at which one good can be exchanged for another and have both parties benefit

Quantity Demanded

The amount of a good or service consumers are willing and able to buy at some specific price. It is shown as a single point in a demand curve

Demand curve

A graphical representation of the demand schedule. It shows the relationship between quantity demanded and price

Law of Demand

States that a higher price for a good or service, all other things being equal, leads to people to a smaller quantity demanded of that good or service

Change in Demand

A shift of the demand curve, which changes the quantity demanded at any given price

Movement along the Demand Curve

A change in the quantity demanded of a good that is the result of a change in that good's price

Substitutes

Goods that are meant to be used in place of another. A rise in the price of one of the goods leads to an increase in demand for the other good

Complements

Goods that are bought together to be used together. A rise in the price of one of the goods leads to a decrease in demand for the other good

Normal Good

When a rise in consumer income increases the demand for the good and vice versa

Inferior Good

When a rise in consumer income decreases the demand for the good and vice versa

Quantity Supplied

The actual amount of a good or service people are willing to sell at some specific price

Supply curve

The relationship between the quantity supplied and the price

Law of Supply

States that all other things being equal, the price and quantity supplied of a good are positively or directly related

Change in Supply

A shift of the supply curve, which indicates a change in the quantity supplied at any given price

Movement along the Supply

A change in the quantity supplied of a good arising from a change in the good's price

Input

A good or service that is used in the production of another good or service

Tax

Treated as an input cost, these are fees producers must pay to the federal government

Subsidy

Treated as an input cost, these are payments from the government to producers to assist in the production of certain goods or services that are deemed beneficial to society

Substitutes in Production

Goods that producers can use the same inputs to make either one good or the other

Complements in Production

Goods are treated as these if increased production of either good creates more of the other good

Equilibrium

The point where QS = QD. This is the intersection point between the supply and demand curve

Surplus

Also known as excess supply and caused by a price floor, this exists at a price above equilibrium where QS > QD

Shortage

Also known as excess demand and caused by a price ceiling, this exists at a price below equilibrium where QS > QD
