Inferior Goods:Inferior goods are consumer goods where demand decreases as consumer income increases. As people have more money to spend, they tend to purchase less of these goods, which are considered less desirable or necessary.
Demand Curve:The demand curve represents the relationship between the price of a good and the quantity demanded of that good, with all other factors held constant.
Income Elasticity of Demand:Income elasticity of demand measures the responsiveness of demand to changes in consumer income, and is used to classify goods as normal, inferior, or luxury.
