Effective supply is the total amount of a commodity

Effective supply is the total amount of a commodity "offered for sale at a market place". It represents the actual quantity of a product or service that producers are willing and able to sell at a given price and at a given point in time. Effective supply takes into account the production capacity of producers, their willingness to sell their products, and the prevailing market conditions such as the price level and demand for the product. The effective supply of a commodity reflects the real availability of the product in the market and is a critical factor that affects its price and quantity sold. Therefore, effective supply refers to the total amount of a commodity that is available for sale in a given market at a given time.
