Economic rent

In economics, economic rent is any payment to a factor of production in excess of the cost needed to bring that factor into production. In classical economics, economic rent is any payment made (including imputed value) or benefit received for non-produced inputs such as location (land) and for assets formed by creating official privilege over natural opportunities (e.g., patents). In neoclassical economics, economic rent also includes income gained by beneficiaries of other contrived exclusivity, such as labor guilds and unofficial corruption.
