➤ How does a change in income affect the demand curve?
A rise in consumer income shifts the demand curve right for normal goods and left for inferior goods. Higher income increases willingness to buy more of normal goods at every price. For inferior goods, higher income reduces demand as consumers substitute toward better alternatives. The slope and intercept remain but the entire curve moves.
