List all the influences on selling plans, and for each influence, say whether it changes supply

What will be an ideal response?

Changes in the price of the good change the quantity supplied. They do not change the supply of the good.
Influences that change the supply of a good include:
• Prices of factor of production. A rise (fall) in the price of a factor of production increases firms' costs of production and decreases (increases) the supply of the good.
• Prices of related goods produced. If the price of a substitute in production rises (falls), firms decrease (increase) their sales of the original good and the supply for the original good decreases (increases). A rise (fall) in the price of a complement in production increases (decreases) production of the original good, causing the supply of the original good to increase (decrease).
• The expected future price of the good. A rise (fall) in the expected future price of the good decreases (increases) the amount suppliers sell today. This change in expectations decreases (increases) the supply in the current period.
• The number of sellers. An increase (decrease) in the number of sellers in a market increases the quantity of the good available at every price, and increases (decreases) the supply.
• Technology. An advance in technology increases the supply.
• The state of nature. A good (bad) state of nature, such as good (bad) weather for agricultural products, increases (decreases) the supply.
