Which of the following causes a change in beef demand when consumer income changes?

• A. Increased income from consumers
• B. A decrease in price
• C. An increase in supply
• D. A technological improvement in production

Answer: (A)

When non-price factors change, demand can shift. Beef is a normal good, so an increase in consumer income raises what people are willing and able to buy at each price, shifting the beef demand curve to the right. In other words, higher income expands overall demand for beef, independent of its price. The other scenarios affect quantity demanded or supply, not the demand curve itself: a price change causes movement along the same demand curve, and a change in supply (from tech or production) shifts the supply curve rather than demand.
