Study Notes
Determinants of Demand
- Five primary determinants include:
- Price of the good or service
- Consumers' income
- Prices of related goods (complementary and substitute)
- Tastes or preferences of consumers
- Consumer expectations
Demand Curve Representation
- The demand curve illustrates the relationship between price and quantity demanded, typically downward sloping.
Demand Line Movement
- Demand line shifts occur when non-price factors change, resulting in movements either right (increase) or left (decrease) on the demand graph.
Increased Demand Visualization
- Increased demand is shown on a demand curve with a "before and after" diagram, clearly labeling original and new demand lines (D1 and D2).
Identifying Price Changes Impact
- Economists analyze the effect of price changes on demand by holding other determinants constant, allowing focus solely on price variations.
Ceteris Paribus Principle
- The assumption that other factors remain unchanged while observing price effects is known as the ceteris paribus assumption, a concept rooted in Latin meaning "other things remaining the same."
Conditions of Demand
- Factors influencing demand beyond price are termed conditions of demand, essential for assessing market dynamics.
Post-Demand Curve Analysis
- After drawing the demand curve, it’s crucial to evaluate how changes in any constant conditions affect the curve's stability.
Nature of Demand Increase
- An increase in demand reflects higher quantities sought at every price point, resulting in a rightward shift on the demand curve.
Complementary Goods
- Complementary goods, like fish and chips, see increased demand for one when the price of the other decreases, making the combination more affordable.
Substitute Goods
- Substitute goods, such as tea and coffee, indicate that an increase in the price of one leads consumers to switch preferences to the other, boosting its demand.
Inferior Goods
- Inferior goods experience decreased demand as consumer incomes rise; for instance, if income allows for purchasing steak, consumers may buy less mince.
Giffen Goods
- Giffen goods are essential staples; a drop in real income can cause increased consumption of these goods, highlighting an inverse relationship with price.
Causes of Demand Increase
- Demand can increase due to:
- Rise in consumers’ real income
- Shift in consumer preferences towards the good
- Increase in the price of a substitute
- Decrease in the price of a complementary good
Decrease in Demand
- A decrease in demand manifests as a leftward shift on the demand curve, indicating that less is sought at every price level.
