What is an Inferior Good?
An inferior good is a type of product whose demand decreases as consumers’ income increases.
In other words, when people earn more money, they tend to buy less of the inferior good and switch to higher-quality alternatives. On the other hand, when income falls, demand for inferior goods rises because they are more affordable.
A common example of an inferior good is instant noodles. A person with a low income may buy instant noodles frequently because they are cheap and easy to prepare. However, when their financial situation improves, they might opt for healthier or more expensive alternatives like fresh pasta or dining at restaurants.
Key Characteristics of Inferior Goods
- Income Elasticity of Demand is Negative: The demand for an inferior good decreases as income rises and increases when income falls.
- Availability of Superior Alternatives: Inferior goods often have better-quality substitutes that consumers prefer when they can afford them.
- Common in Budget-Conscious Consumption: These goods are more popular among lower-income groups or during economic downturns.
Inferior Goods vs. Normal Goods vs. Giffen Goods
| Feature | Inferior Goods | Normal Goods | Giffen Goods |
| Definition | Goods whose demand decreases as consumer income increases | Goods whose demand increases as consumer income increases | A special type of inferior good where demand increases despite a price rise due to lack of substitutes |
| Income Effect | Negative – higher income leads to lower demand | Positive – higher income leads to higher demand | Strong negative income effect that outweighs the substitution effect |
| Price Effect | If the price decreases, demand may increase | If the price decreases, demand increases | If the price increases, demand increases (violates the law of demand) |
| Examples | Instant noodles, public transport, low-cost clothing | Fresh food, branded clothes, private transport | Staple food like rice, bread, and potatoes in low-income groups |
| Consumer Behavior | As income rises, consumers switch to better alternatives | As income rises, consumers buy more of the good | Due to extreme poverty, consumers cannot afford alternatives and buy more even as price rises |

- Y-axis (vertical) represents consumer income.
- X-axis (horizontal) represents the quantity demanded.
- The demand curve slopes downward, showing an inverse relationship between income and demand for inferior goods.
Key Points:
- At an income level of $100, the quantity demanded is 2.
- When income increases to $200, the quantity demanded drops to 1.
- This shows that as people earn more, they buy less of the inferior goods.
- The downward-sloping demand curve highlights this negative relationship.
