Study Notes
Types of Demand
- Price Demand: Quantities of goods/services consumers will buy at a specific price, assuming other factors remain constant.
- Income Demand: Quantities of goods/services demanded at varying income levels, with all else held constant.
- Cross Demand: Demand for a product influenced by the price of related goods rather than its own price.
- Direct Demand: Demand for goods/services that satisfy an individual's needs immediately.
- Derived (Indirect) Demand: Demand for goods/services needed to produce other goods, fulfilling consumer needs indirectly.
- Joint Demand: Demand for multiple interconnected products necessary for producing a single item (e.g., oven, flour for bread).
- Composite Demand: Goods/services utilized for various purposes simultaneously (e.g., coal for energy and steel production).
Price, Income, and Cross Elasticities
- Price Elasticity of Demand (PED): Measures how quantity demanded responds to price changes.
- Income Elasticity of Demand (YED): Measures how quantity demanded changes in response to income variations.
- Cross Price Elasticity of Demand (XED): Assesses how the quantity demanded for one good reacts to the change in price of another good.
Numerical Values Interpretation
- PED Types:
- Unitary Elastic: Proportional change in demand with price changes.
- Perfectly Elastic: Infinite sensitivity to price changes.
- Relatively Elastic: Significant sensitivity to price changes.
- Perfectly Inelastic: No change in demand regardless of price changes.
- Relatively Inelastic: Minimal sensitivity to price changes.
- YED Types:
- Inferior Goods: Demand decreases as income increases.
- Normal Goods: Demand increases with income.
- Luxury Goods: Demand increases more than proportionally with income.
- XED Types:
- Substitutes: Positive elasticity; an increase in the price of one increases demand for the other.
- Complementaries: Negative elasticity; an increase in price of one decreases demand for the other.
- Unrelated Goods: Zero elasticity; changes in price of one do not affect demand for the other.
Factors Influencing Price Elasticities
- Availability of Substitutes: More substitutes tend to make demand more elastic as consumers can easily switch.
- Complementary Goods: The presence of complementary goods can increase demand.
- Consumer Preferences: Changes in preferences can shift demand curves.
- Income Levels: Rising incomes generally increase demand for normal goods.
Law of Demand
- Inverse Relationship: As prices rise, quantity demanded falls; as prices drop, quantity demanded increases.
- Diminishing Marginal Utility: Consumers prioritize the use of goods to satisfy their most urgent needs first.
- Demand Curve: Visually represents the quantity demanded at various price levels, demonstrating the inverse relationship between price and demand.
- Market Demand Curve: Aggregates individual demand at various prices across all consumers.
Determinants of Demand
- Price of the Product: Critical parameter influencing consumer decisions; follows the law of demand.
- Demand Curve/Schedule: Tools to visualize and analyze quantity demanded at specific price points.
- Elastic vs. Inelastic Demand: Elastic demand signifies significant changes with price shifts, while inelastic indicates minimal responsive changes.
General Understanding
- Economics studies the allocation of scarce resources to satisfy unlimited wants.
- The law of demand is fundamental in explaining market behaviors, showing how price alterations affect consumer demand.
