A supply schedule is characterized primarily by the following:
- It lists supply for a specific good.
A supply schedule typically provides a table that shows the relationship between price and quantity supplied for a specific good, indicating how much of that good producers are willing to sell at various price levels.
The other statements, while related to supply, do not accurately define a supply schedule:
- "It shows the quantity supplied at only one price" is incorrect, as a supply schedule typically displays quantities at multiple price levels.
- "It is sensitive to changes in the costs of labor and parts" refers to factors affecting supply but does not define a supply schedule itself.
- "It shows the factors that could influence supply" describes broader market conditions rather than the schedule itself.
Thus, the most accurate characterization of a supply schedule is that it lists supply for a specific good.
