What is the concept of an inferior good in economics and how does it impact consumer behavior and market dynamics?

An inferior good in economics is a product that people buy less of when their income increases. This is because as people become wealthier, they tend to prefer higher-quality goods and services. The impact of inferior goods on consumer behavior is that they are seen as less desirable as income rises. This can lead to shifts in demand and can affect market dynamics by influencing the prices and quantities of goods and services being bought and sold.
