Which term describes changes in supply conditions that cause shifts of the supply curve?

• A. Change in Supply
• B. Increase in Supply
• C. Decrease in Supply
• D. Contraction in Supply

Answer: (A)

Changes in supply conditions cause the entire supply curve to shift because they alter the quantities producers are willing to supply at every price. The term for these changes is change in supply. It covers factors like production costs, technology, prices of other goods, taxes or subsidies, expectations, the number of sellers, and external conditions. When supply conditions improve, the curve shifts to the right (more is supplied at each price); when they worsen, it shifts to the left (less is supplied). The other phrases describe the direction of the shift or movement along the curve, not the cause of the shift.
