What effect does a decrease in consumer income have on inferior goods?

A decrease in consumer income leads to an increase in demand for inferior goods because these goods are typically considered lower-quality alternatives to more expensive items. When consumers experience a drop in income, they tend to buy more inferior goods as a way to maintain their consumption levels while economizing. This behavior reflects the very nature of inferior goods, which are defined as goods for which demand rises when consumer incomes fall.

As consumers substitute away from more expensive goods they can no longer afford, the demand for inferior goods increases. This is contrary to normal goods, where demand decreases as income decreases. The relationship between income and demand for inferior goods is a fundamental concept in microeconomics, illustrating how changes in consumer income can impact purchasing behavior.
