Term factor supply Definition: The willingness and ability of scarce resources or factors of production to offer their services for use in productive activities. Like other types of supply, factor supply relates price and quantity. Specifically, factor supply is the range of factor quantities that are supplied at a range of factor prices. This is one half of the factor market. The other half is factor demand. The factors of production subject to factor supply include any and all of the four scarce resources--labor, capital, land, and entrepreneurship. However, because labor involves human beings directly, it is the factor that tends to receive the most scrutiny and analysis.
