Question

which of the following shifts a supply curve for a product? buyers purchasing less of a product shortages of a product sequential increases in a product’s market price changes in technology, resource prices, and future price expectations i dont know yet

Explanation:

To determine what shifts a supply curve, we analyze each option:

• "Buyers purchasing less" relates to demand (buyer behavior), not supply.
• "Shortages of a product" are a result of supply - demand imbalance, not a supply shifter.
• "Sequential increases in a product’s market price" cause a movement along the supply curve (quantity supplied change), not a shift.
• "Changes in technology, resource prices, and future price expectations" are non - price determinants of supply. Technology improvements, resource price changes (cost of production), and future price expectations (producers' plans) shift the entire supply curve.
• "I DON'T KNOW YET" is not a valid economic explanation.

Answer:

The option "Changes in technology, resource prices, and future price expectations" (the third option from the left among the non - "I DON'T KNOW YET" options)
