Term market supply Definition: The total supply of every seller willing and able to sell a good. Market supply is found by combining the individual supplies of every firm or producer willing and able to sell a particular good. The market supply curve is found by horizontally adding all individual supply curves, that is, sum up the quantities supplied by all sellers at each and every price. Market supply operates according to the law of supply, as illustrated by a upward-sloping market supply curve. For higher prices the quantity supplied by all sellers in the market combined is greater than the quantity supplied for lower prices.
