A normal good is a type of product or service that experiences an increase in demand as consumer income rises. This means that as people’s income increases, they are more likely to purchase this good or service. Normal goods are considered to be essential or necessary for daily life, and their demand is directly linked to the level of disposable income a person has. Examples of normal goods include food, clothing, and housing. As people’s income increases, they tend to spend more on these goods, leading to an increase in demand and sales. In contrast, as income decreases, the demand for normal goods also decreases. Normal goods are an important indicator of consumer behavior and economic trends, making them a crucial concept in the study of economics.
