Questions and Answers
How is the market supply curve derived?
It is derived by horizontally summing all individual supply curves.
What does the law of supply state?
It states that as the price of a good increases, the quantity supplied increases, and vice versa.
What is the difference between a change in supply and a change in quantity supplied?
A change in supply involves shifts of the curve due to factors like technology or input prices, while a change in quantity supplied refers to movements along the curve due to price changes.

Study Notes
Demand, Individual Demand, and Market Demand
- Demand refers to the quantities of goods or services buyers are willing and able to purchase at various prices within a given time frame, assuming other factors remain constant.
- Individual demand signifies the demand from a single consumer for goods and services.
- Market demand is the total demand across all individual consumers in a specific market.
Law of Demand
- The law of demand indicates that an increase in the price of a good typically results in a decrease in the quantity demanded, while a decrease in price leads to an increase in quantity demanded.
Demand Schedule
- A demand schedule illustrates the relationship between individual demand and market demand, typically represented through a table.
Movement Along a Demand Curve vs. Shift of a Demand Curve
- A change in the price of a good causes a movement along the demand curve (change in quantity demanded).
- Changes in factors such as consumer income or preferences lead to a shift of the demand curve (change in demand).
Determinants of Demand
- Key determinants include:
- Price of the good itself
- Consumers' preferences and tastes
- Consumers' income levels
- Market size (number of potential consumers)
- Prices of related goods (substitutes and complements)
- Expectations regarding future prices
- Additional influencing factors may include geographical location, culture, government policies, education level, age demographics, and seasonal trends.
Supply, Individual Supply, and Market Supply
- Supply represents the producer's capability and willingness to provide various quantities of goods and services at different price levels over time.
- Individual supply refers to the supply from a single seller.
- Market supply is derived by aggregating all individual supply curves horizontally.
Law of Supply
- The law of supply states that an increase in the price of a good will lead to an increase in the quantity supplied, while a decrease in price will result in a decrease in quantity supplied.
Determinants of Supply
- Main determinants include:
- Price of the good itself (affects movement along the supply curve)
- Costs and availability of production factors
- Prices of related goods
- Technological advancements
- Government or economic policies
- Producers' expectations about future prices
- Number of suppliers in the market
Change in Supply vs. Change in Quantity Supplied
- Change in price results in change in quantity supplied (movement along the curve).
- Changes in production costs, input prices, technological factors, or prices of related goods lead to a change in overall supply (shift of the curve).
Key Concepts Recap
- Understanding demand and supply dynamics is crucial for analyzing market behaviors.
- Distinguishing between shifts in demand/supply versus movements along the curves is essential for comprehensive economic analysis.
