Study Notes
Determinants of Demand
- Internal Factors:
- The price of a product is influenced by its production cost.
- Higher prices generally lead to lower demand.
- External Factors:
- Price of Related Goods:
- Substitute Goods are alternatives (e.g., bus vs. LRT, coffee vs. tea).
- An increase in the price of a substitute good leads to an increase in demand for the original good, and vice versa.
- Complementary Goods are used together (e.g., computer and disk, pen and ink).
- An increase in the price of a complementary good leads to a decrease in demand for the original good, and vice versa.
- Consumers' Income:
- Increased income generally leads to increased demand for normal goods (e.g., cars, shirts, books).
- Increased income generally leads to decreased demand for inferior goods (e.g., low-grade potatoes, used cars).
- Consumers' Fashion Tastes and Preferences:
- Fashion trends and preferences influence demand, leading to increases in demand for fashionable products and decreases for outdated ones.
- Population or Number of Buyers:
- A larger population leads to higher demand.
- Price of Related Goods:
Price Elasticity of Demand (PED)
- PED measures the responsiveness of quantity demanded to changes in price.
- The equation for calculating PED: (Percentage change in quantity demanded) / (Percentage change in price).
- Range of PED Values:
- Perfectly Inelastic Demand (PED = 0): Demand is unresponsive to price changes.
- Perfectly Elastic Demand (PED = ∞): Demand is infinitely responsive to price changes.
- Unit Elastic Demand (PED = 1): Percentage change in quantity demanded equals the percentage change in price.
- Elastic Demand (PED > 1): Percentage change in quantity demanded is greater than the percentage change in price.
- Inelastic Demand (PED < 1): Percentage change in quantity demanded is less than the percentage change in price.
Total Revenue and PED
- Elastic Demand:
- Decreasing price increases total revenue.
- Increasing price decreases total revenue.
- Inelastic Demand:
- Decreasing price decreases total revenue.
- Increasing price increases total revenue.
- Unitary Demand:
- Changes in price do not affect total revenue.
Price Elasticity of Supply (PES)
- PES measures the responsiveness of quantity supplied to changes in price.
- Range of PES Values:
- Perfectly Inelastic Supply (PES = 0): Supply is unresponsive to price changes (short-run scenario).
- Perfectly Elastic Supply (PES = ∞): Supply is infinitely responsive to price changes.
- Inelastic Supply (PES < 1): Percentage change in quantity supplied is less than the percentage change in price.
- Elastic Supply (PES > 1): Percentage change in quantity supplied is greater than the percentage change in price.
- Unit Elastic Supply (PES = 1): Percentage change in quantity supplied equals the percentage change in price.
