When discussing economic concepts, it is important to understand the difference between normal and inferior goods. Normal goods are goods that consumers purchase more of when their income increases, while inferior goods are goods that consumers purchase less of when their income increases. We will discuss what distinguishes normal goods from inferior goods and why understanding the difference between them is important for businesses and consumers alike.
Normal vs. inferior goods
| Normal Goods | Inferior Goods |
|---|---|
| Normal goods are goods for which demand increases as consumer income increases, assuming all other factors remain constant. These are goods that people tend to buy more of as they become wealthier. | Inferior goods are goods for which demand decreases as consumer income increases, assuming all other factors remain constant. These are goods that people tend to buy less of as they become wealthier, often because they can afford to buy higher-quality substitutes. |
| Examples of normal goods include luxury cars, restaurant meals, and high-end clothing. | Examples of inferior goods include fast food, generic products, and used cars. |
| The income elasticity of demand for normal goods is positive, meaning that as income increases, the quantity demanded of these goods increases at a proportionately greater rate. | The income elasticity of demand for inferior goods is negative, meaning that as income increases, the quantity demanded of these goods decreases at a proportionately greater rate. |
| Normal goods are often associated with higher quality, luxury, or status. Consumers tend to perceive these goods as better than their substitutes. | Inferior goods are often associated with lower quality or lower status. Consumers may perceive these goods as less desirable than their substitutes. |
| The demand for these goods is generally not very price-sensitive, meaning that changes in price do not have a significant impact on consumer demand. | The demand for these goods is generally price-sensitive, meaning that changes in price have a significant impact on consumer demand. As prices increase, consumers may seek out higher-quality substitutes. |
The definition of a normal good
A normal good is a type of good whose demand increases as income increases. This means that as the consumer’s income rises, so does their demand for the good. Normal goods are typically the more expensive and luxurious items, such as cars, jewelry, and vacations.
The demand for these types of goods increases when the consumer has more disposable income to spend on them. Normal goods are often necessities, rather than luxuries, and they form the backbone of a healthy economy. For normal goods, demand rises when income increases. Examples of normal goods include food, clothing, housing, medical care, education, and transportation.
The definition of an inferior good
An inferior good is a type of good for which demand decreases when income increases and vice versa. This means that, as income rises, consumers are less likely to buy the product. For example, when incomes increase, consumers tend to switch from inferior goods such as generic food items and budget clothing to more expensive brands and products. Inferior goods, demand falls when income increases.
The key differences between the normal and inferior goods
Normal goods and inferior goods differ in their relationship to consumer income. A normal good is good that experiences an increase in demand when consumer income rises. whereas, an inferior good is good that experiences a decrease in demand when consumer income rises.
For example, when consumer income rises, they will typically purchase more luxury items like a new car or designer clothing. These are considered normal goods since the demand for them increases with consumer income. On the other hand, when consumer income rises, they may purchase fewer items like canned goods or second-hand clothes. These are considered inferior goods since the demand for them decreases with consumer income.
When it comes to consumer behavior, the demand for normal goods tends to be more elastic than the demand for inferior goods. This means that when prices for normal goods increase, consumers will respond by purchasing less of them, while when prices for inferior goods increase, consumers may not change their purchasing habits significantly.
Hence, the relationship between income changes and the demand curve for normal goods vs. inferior goods is also different. As income increases, the demand curve for normal goods will shift to the right due to increased demand, while the demand curve for inferior goods will shift to the left due to decreased demand.
Overall, understanding the difference between normal and inferior goods can help businesses better understand consumer behavior and make informed decisions on pricing and marketing strategies.

Examples of normal and inferior goods
Normal goods are items that consumers purchase more of as their income increases, while inferior goods are those purchased less of when income increases. Common examples of normal goods include everyday items like food, clothing, and household appliances. As your income rises, you may choose to purchase higher quality and more expensive versions of these products.
On the other hand, inferior goods are products that people typically buy less of as their incomes rise. Examples of inferior goods include low-cost products such as fast food, inexpensive clothing, and generic store brands. As your income goes up, you may opt for more expensive or higher-quality versions of these products.
It’s important to understand the difference between normal and inferior goods when analyzing consumer behavior. This understanding can be used to make decisions about pricing, marketing, and other strategies for businesses. Knowing the differences between normal and inferior goods can also help you decide which products to purchase at different income levels.
Consumer behavior towards normal and inferior goods
When it comes to consumer behavior, normal and inferior goods have very different reactions.
The most significant difference between normal and inferior goods is in how they react to changes in a consumer’s income. When a consumer’s income rises, they tend to buy more of the normal goods they enjoy, and less of the inferior goods they used to purchase.
This is because they can now afford higher quality items or more expensive versions of the same item. On the other hand, when a consumer’s income falls, the opposite happens – they will buy more of the inferior goods, as they cannot afford higher quality items.
Relationship between income changes and demand curve
A normal good is one whose demand increases when consumer incomes rise. This means that the demand curve for a normal good will shift to the right when income levels increase, as consumers are willing to pay more for the good.
On the other hand, an inferior good is one whose demand decreases when consumer incomes rise. This means that the demand curve for an inferior good will shift to the left when income levels increase, as consumers are less willing to pay for the good.
The relationship between income changes and the demand curves of normal and inferior goods can be seen in the following example. Suppose the price of bread is $2 per loaf and it is a normal good. If consumer incomes increase, the demand for bread will also increase and the demand curve will shift to the right. The result is that consumers will be willing to pay more for bread, so the equilibrium price of bread will increase from $2 to $2.50.
On the other hand, suppose the price of rice is $1 per kilogram and it is an inferior good. If consumer incomes increase, the demand for rice will decrease and the demand curve will shift to the left. The result is that consumers will be less willing to pay for rice, so the equilibrium price of rice will decrease from $1 to $0.75.
So the difference between normal goods and inferior goods can be seen in how their demand curves respond to a change in income. Normal goods have a rightward shifting demand curve in response to a rise in income, while inferior goods have a leftward shifting demand curve.
