The production factor, whose entire world supply is fixed is

The production factor whose entire world supply is fixed is "land". This means that the total amount of land available in the world is limited, and cannot be increased beyond its current amount. Unlike other factors of production such as skilled labor, capital goods, and entrepreneurship, land is a finite resource that cannot be created or expanded. This has important implications for industries and economies that rely on land for production. It means that as demand for land-based resources and activities grows, such as agriculture or real estate development, competition for access to limited land resources will intensify. This can lead to higher prices for land, which in turn can affect the profitability and viability of certain industries. Understanding the limited supply of land is an important consideration for businesses and policymakers when making decisions about resource allocation, land use planning, and economic development strategies.
