Inferior Goods: Violating The Law Of Demand?

An inferior good is an economic term used to describe a good whose demand decreases when consumers' incomes increase. These goods are typically more affordable substitutes for more expensive goods and are favoured by consumers with lower incomes or during economic downturns. As incomes rise and the economy improves, consumers tend to opt for more costly substitutes. While inferior goods are generally subject to the Law of Demand, which states that demand increases as price decrease, there are exceptions in the form of Giffen and Veblen goods, which exhibit a positive relationship between price and demand.

Giffen goods are an exception to the Law of Demand

The concept of Giffen goods was introduced by Sir Robert Giffen. Giffen observed that when the price of bread rose, low-paid British workers in the early 19th century bought more bread. This was because, as the price of bread increased, workers spent less on other, more expensive foods, and bought more bread to make up the calories. This phenomenon is also observed with staple foods like rice, where people with lower incomes will buy more rice and less of other, more expensive foods when the price of rice increases. The Irish Potato Famine is a classic example of the Giffen goods concept. As the price of potatoes—a staple in the Irish diet—increased, people bought fewer luxury foods and purchased more potatoes.

Giffen goods are rare and can be difficult to prove. However, economists generally agree that there are cases where the Law of Demand is violated. Other exceptions to the Law of Demand include Veblen goods, essential goods, and changes in consumer income. Veblen goods, conceptualized by economist Thorstein Veblen, are products that become more valuable and desirable as their price increases. This is often the case with luxury goods, precious metals and stones, and expensive vehicles. As the price of these goods increases, so does their demand, as they become a symbol of status. Essential goods are another exception to the Law of Demand, as people will continue to buy necessities like medications or staple foods even when prices increase. Finally, changes in consumer income can also lead to exceptions to the Law of Demand. If a household's income increases, they may buy more of a product regardless of a price increase, thereby increasing the demand for that product. Similarly, if a household's income decreases, they may defer purchasing a product even if its price drops.

Veblen goods are another exception

Veblen goods are typically high-quality, exclusive products with strong brand identities that are synonymous with luxury. Examples include designer jewellery, expensive watches, yachts, luxury cars, fine wines, and celebrity-endorsed perfumes. These goods are generally targeted at affluent individuals who value the utility and status associated with them. The demand for Veblen goods reflects consumer tastes and preferences, with higher prices enhancing their attraction to those who prioritise status.

The concept of the Veblen effect, or the Veblen theory, was introduced by Veblen in his 1899 book "The Theory of the Leisure Class". The theory suggests that lowering the price of a Veblen good may initially increase demand but will eventually decrease the quantity demanded. This is because the high price is part of the product's appeal, and a lower price may diminish its perceived status.

The existence of Veblen goods has raised concerns about their wastefulness and financial and social consequences. Consuming Veblen goods can lead to conspicuous demonstrations of unequal wealth distribution and potential changes to tax formulas. Additionally, this type of consumption may contribute to future pollution exacerbation. However, one exception to this negative outcome is ethical consumers who engage in virtue signalling through their consumption of ethically manufactured goods and services.

In summary, Veblen goods are an exception to the law of demand due to their unique relationship between price and demand. The higher prices of these luxury goods make them more desirable as status symbols, resulting in an upward-sloping demand curve. This contradicts the basic law of demand, which states that quantity demanded has an inverse relationship with price.

Inferior goods are dictated by consumer behaviour

The demand for inferior goods is dictated by consumer behaviour, specifically consumer income. An inferior good is an economic term that describes a good whose demand drops when people's incomes rise. When incomes are low or the economy is in decline, inferior goods become a more affordable substitute for more expensive goods. Conversely, when incomes rise, consumers are more willing to spend on more costly substitutes.

Demand for inferior goods is typically driven by people with lower incomes or when there is a contraction in the economy. For example, when people have less money, they tend to buy cheaper, generic-brand products. However, when their incomes rise, they often switch to more expensive items. Groceries are among the most common examples of inferior goods because food is a necessity that must always be acquired. For instance, an individual may opt for an inferior product such as canned meat or frozen food instead of steak. No-name grocery store products such as cereal or peanut butter are other examples of inferior goods.

However, it is important to note that some customers may not change their behaviour and continue to purchase inferior goods even when their income increases. For instance, a consumer may continue to buy coffee from McDonald's because they prefer it over Starbucks, or they may find a no-name grocery product that they like better than the name-brand alternative.

In rare cases, inferior goods can violate the Law of Demand, which states that the quantity demanded for a good or service rises as the price falls, and decreases as the price increases. A Giffen good is an example of an inferior good that violates the Law of Demand. When the price of bread (a staple food) rose, low-paid British workers in the early 19th century were compelled to purchase more bread, even though it was now more expensive. They substituted bread for meat to maintain their food and calorie intake.

Demand for inferior goods is driven by lower incomes

In economics, inferior goods are goods that people demand less of as their incomes rise. The term "'inferior" refers to the good's affordability, not its quality. Demand for inferior goods is driven by lower incomes, as they are relatively cheaper substitutes for more expensive goods. When people's incomes decrease, they tend to buy these kinds of products, and when their incomes rise, they often switch to more expensive items.

Demand for inferior goods is dictated primarily by consumer behaviour, particularly by people with lower incomes or when there is a contraction in the economy. Examples of inferior goods include cheap cars, public transportation, payday lending, and inexpensive food. When money is tight, people may opt for cheaper cars or public transit options like buses or trains. Similarly, they may resort to payday loans, which are marketed to people with low incomes, instead of more conventional loans with better terms.

The demand for inferior goods is influenced by two economic phenomena: the substitution effect and the income effect. The substitution effect refers to the change in demand for a good when its relative price changes compared to substitute goods. When the price of an inferior good decreases, it becomes relatively cheaper than its substitutes, and consumers may choose it over more expensive options. However, when the price of an inferior good increases, consumers may opt for substitute goods instead.

The income effect describes the relationship between a consumer's income and their demand for a good. Inferior goods exhibit a negative income effect, where their consumption decreases as consumer income increases. As people's incomes rise, they can afford a bundle of goods that provide higher utility, and thus they may choose to purchase more expensive substitutes instead of inferior goods.

It is important to note that not all consumers will change their behaviour when their income changes. Some may continue to purchase inferior goods even after their income increases, due to preferences or other factors. Additionally, the substitution effect is typically larger than the income effect, as consumers generally allocate a small amount of their income to any given good, resulting in insignificant changes in demand compared to the substitution effect.

Inferior goods are the opposite of normal goods

Inferior goods, on the other hand, are goods whose demand decreases when consumer income rises (or demand increases when consumer income decreases). This behaviour is unlike the supply and demand behaviour of normal goods, where the opposite is observed. The term "inferior" in this context indicates affordability, not quality. Inferior goods are affordable and adequately fulfil their purpose, but as consumers' incomes increase, they tend to decrease their purchases of inferior goods, opting for normal goods or luxury goods instead.

Examples of inferior goods include store-brand grocery products, instant noodles, certain canned or frozen foods, cheaper cars, and inter-city bus services. As incomes rise, consumers may shift to more expensive alternatives, such as more appealing or nutritious foods, luxury cars, or faster modes of transportation.

The demand for inferior goods is influenced by the substitution effect and the income effect. The substitution effect refers to the change in demand for a good when its relative price changes compared to substitute goods. When the price of an inferior good decreases, its consumption may decrease due to consumers opting for more expensive substitutes. The income effect describes the relationship between an increase in real income and a decrease in demand for inferior goods. As consumers' incomes rise, they can afford higher-utility alternatives, leading to a decrease in demand for inferior goods.
