Study Notes
Market Dynamics
- Price in a market system is determined by interactions between buyers and sellers.
- Demand combines the desire to own a product with the ability to pay for it.
Demand Fundamentals
- The Law of Demand states prices inversely relate to quantity demanded; lower prices lead to higher demand.
- Substitution Effect occurs when consumers buy less of an expensive good and more of a cheaper alternative.
- Income Effect describes changes in consumption due to changes in real income levels.
Demand Measurement Tools
- A Demand Schedule shows the quantities purchased at various prices by an individual.
- A Market Demand Schedule aggregates the demand of all consumers at each price point.
- The Demand Curve visually represents price and quantity demanded relationship, always sloping downward.
Analytical Terms and Movements
- "Ceteris Paribus" means "all other things held constant," often used in economic models to isolate factors.
- A price change results in movement along the demand curve, indicating a change in quantity demanded.
- A shift in the demand curve occurs when ceteris paribus assumptions are lifted, indicating a change in demand conditions.
Demand Curve Shifts
- The demand curve shifts leftward when demand decreases and rightward when demand increases.
- Normal Goods see increased demand with rising income, while Inferior Goods see decreased demand with rising income.
Expectations and Demand
- Future price expectations can alter current demand; anticipated price decreases lower present demand, while anticipated increases raise it.
Population and Advertising Impacts
- Increasing population drives demand for essential goods like housing and food.
- Advertising significantly shapes consumer trends and influences demand.
Complementary and Substitute Goods
- Complements are goods consumed together; a sale of one typically increases demand for the other.
- Substitutes replace one another; if the price of one rises, demand for its alternatives generally increases.
Elasticity of Demand
- Elasticity measures consumer responsiveness to price changes, categorized into inelastic and elastic.
- Inelastic goods remain essential regardless of price changes, while elastic goods see decreased demand with even small price increases.
- Total Revenue shifts with price changes, with elastic demand resulting in decreased total revenue when prices rise and increased revenue when they fall.
- Inelastic goods yield increased total revenue when prices rise and decreased revenue when they fall, as they attract the same customers rather than new ones.
Necessities vs. Luxuries
- Necessities are typically inelastic; consumers continue purchasing despite price increases.
- Luxuries are elastic; demand drops significantly when prices increase.
Total Revenue Insight
- Total Revenue signifies earnings from sales before accounting for production costs, crucial for firms to optimize profit strategies based on demand elasticity.
