Market supply

Market supply is the total amount of an item producers are willing and able to sell at different prices, over a given period of time e.g. one month. Industry, a market supply curve is the horizontal summation of all each individual firm's supply curves.

Market supply is the combined supply of every seller in the market. It is derived by adding the quantity supplied by each seller at different prices. Suppose, for example, that the Shady Valley market for crab puffs contains three sellers--MegaMart Discount Super Center, The Corner Store, and Harry's Hor D'oeuvres.

The market supply curve is obtained by adding together the individual supply curves of all firms in an economy. As the price increases, the quantity supplied by every firm increases, so market supply is upward sloping.

The market supply schedule is a table that lists the quantity supplied for a good or service that suppliers throughout the whole economy are willing and able to supply at all possible prices
