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.
