Study Notes
YED Income Elasticity of Demand
- YED measures the responsiveness of quantity demanded to a change in income.
- It's crucial for understanding consumer behaviour.
- YED = (% change in quantity demanded) / (% change in income)
Types of Goods Based on YED
-
Normal goods: Positive YED; demand increases as income rises.
- Examples include fresh fruit, clothing, and cars
- Necessities have an YED between 0 and +1, meaning that demand rises less than proportionately to income.
-
Luxury goods: High positive YED; demand rises more than proportionately to income.
- Examples include luxury cars, fine wines, and designer goods
-
Inferior goods: Negative YED; demand falls as income increases.
- Examples include cheaper brands of goods, second-hand clothes, and public transport.
Income Elasticity of Demand Examples
- Luxury chocolates: High positive elasticity - demand rises significantly with increased income
- Economy class travel: Low positive elasticity - demand rises slightly with increased income
- Exclusive resorts: High positive elasticity - demand rises significantly with increased income
- Own-label discounters: Low and negative elasticity (potentially) - demand may decrease with increased income
- Urban bus transport: Low and negative elasticity (potentially) - demand may decrease with increased income
- Business class travel: High positive elasticity - demand rises significantly with increased income
- Fine wines and dining: High positive elasticity - demand rises significantly with increased income
- Cigarettes: Low and negative elasticity (potentially) - demand may decrease with increased income
- Economy class travel: Low and negative elasticity (potentially) - demand may decrease with increased income
Tasks
- Construct lists of products showcasing positive/negative YED.
- Illustrate demand curves to visually represent various categories of goods.
- Calculate income elasticity of demand given a scenario.
Applications and Significance
- Knowledge of YED is crucial for firms to anticipate shifts in demand.
- Businesses adjust production and pricing strategies according to rising or falling consumer income.
Further Considerations
- Specific YED values vary depending on the good and the income levels.
- Economic conditions, like recessions, can also impact YED.
Additional Points
- Changes in income influence demand for goods
- Understanding YED is fundamental for businesses and economists
- Income elasticity values indicate whether a product is a necessity, normal good or luxury good
