1. The problem asks how the supply curve shifts when suppliers anticipate a higher future price for wireless earbuds and how the quantity supplied changes at the current price of 4. 2. The supply curve shows the relationship between price and quantity supplied. When suppliers expect higher future prices, they tend to hold back supply now to sell more later at higher prices. This causes the current supply curve to shift left (decrease in supply). 3. A leftward shift means at the same price of 4, the quantity supplied decreases because suppliers supply less now. 4. To draw the new supply curve \(S_2\), shift the original supply curve \(S_1\) to the left. 5. The new point \(A_2\) on \(S_2\) at price 4 will have a lower quantity than the original \(A_1\) point. 6. Summary: Anticipation of higher future prices shifts supply curve left, decreasing quantity supplied at current price 4. Final answer: The supply curve shifts left (decreases), and quantity supplied decreases at price 4.
