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.
