What economic concept describes the total amount of a specific good available to consumers?

The concept that describes the total amount of a specific good available to consumers is supply. Supply refers to the quantity of a product or service that producers are willing and able to sell at a given price over a specific period. It reflects how much of a good is available in the market for consumers to purchase.

Understanding supply is critical in economics because it interacts with demand, influencing pricing and availability in the market. When supply increases, assuming demand stays constant, it can lead to lower prices, while a decrease in supply with constant demand can raise prices. This relationship is foundational in analyzing market behaviors and conditions.

In this context, other terms like demand refer to how much of a good consumers want to buy, market share indicates the portion of the market controlled by a particular company, and equilibrium describes the point where supply equals demand. Thus, supply is the appropriate answer that directly addresses the question regarding the total availability of a specific good for consumers.
