Study Notes
Supply and Demand
Definition
- Supply: The amount of a good or service that producers are willing and able to produce and sell at a given price level.
- Demand: The amount of a good or service that consumers are willing and able to buy at a given price level.
Law of Supply
- As the price of a good increases, the quantity supplied also increases.
- As the price of a good decreases, the quantity supplied also decreases.
Law of Demand
- As the price of a good increases, the quantity demanded decreases.
- As the price of a good decreases, the quantity demanded increases.
Equilibrium
- Occurs when the quantity supplied equals the quantity demanded.
- Equilibrium price: The price at which the supply and demand curves intersect.
- Equilibrium quantity: The quantity at which the supply and demand curves intersect.
Shifts in Supply and Demand
-
Increase in Supply:
- Shifts the supply curve to the right.
- Causes a surplus at the original price level.
-
Decrease in Supply:
- Shifts the supply curve to the left.
- Causes a shortage at the original price level.
-
Increase in Demand:
- Shifts the demand curve to the right.
- Causes a shortage at the original price level.
-
Decrease in Demand:
- Shifts the demand curve to the left.
- Causes a surplus at the original price level.
Factors Affecting Supply and Demand
-
Supply:
- Production costs
- Technology
- Expectations
- Government policies
-
Demand:
- Price of related goods
- Consumer preferences
- Income
- Population and demographics
Supply and Demand
Definition
- Supply refers to the amount of a good or service that producers are willing and able to produce and sell at a given price level.
- Demand refers to the amount of a good or service that consumers are willing and able to buy at a given price level.
Law of Supply
- A direct relationship exists between the price of a good and the quantity supplied: as the price increases, the quantity supplied also increases.
- Conversely, as the price of a good decreases, the quantity supplied also decreases.
Law of Demand
- An inverse relationship exists between the price of a good and the quantity demanded: as the price increases, the quantity demanded decreases.
- Conversely, as the price of a good decreases, the quantity demanded increases.
Equilibrium
- Equilibrium occurs when the quantity supplied equals the quantity demanded.
- The equilibrium price is the price at which the supply and demand curves intersect.
- The equilibrium quantity is the quantity at which the supply and demand curves intersect.
Shifts in Supply and Demand
- An increase in supply shifts the supply curve to the right, causing a surplus at the original price level.
- A decrease in supply shifts the supply curve to the left, causing a shortage at the original price level.
- An increase in demand shifts the demand curve to the right, causing a shortage at the original price level.
- A decrease in demand shifts the demand curve to the left, causing a surplus at the original price level.
Factors Affecting Supply and Demand
- Supply is affected by:
- Production costs
- Technology
- Expectations
- Government policies
- Demand is affected by:
- Price of related goods
- Consumer preferences
- Income
- Population and demographics
