Economic rent

In economics, economic rent is any payment (in the context of a market transaction) to an owner or factor of production in excess of the costs 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 the moral economy of neoclassical economics, economic rent includes income gained by labor or state beneficiaries of other "contrived" (assuming the market is natural, and does not come about by state and social contrivance) exclusivity, such as labor guilds and unofficial corruption.

In the moral economy of the economics tradition broadly, economic rent is opposed to producer surplus, or normal profit, both of which are theorized to involve productive human action. Economic rent is also independent of opportunity cost, unlike economic profit, where opportunity cost is an essential component. Economic rent is viewed as unearned revenue [1] while economic profit is a narrower term describing surplus income earned by choosing between risk-adjusted alternatives. Unlike economic profit, economic rent cannot be theoretically eliminated by competition because any actions the recipient of the income may take such as improving the object to be rented will then change the total income to contract rent. Still, the total income is made up of economic profit (earned) plus economic rent (unearned).

For a produced commodity, economic rent may be due to the legal ownership of a patent (a politically enforced right to the use of a process or ingredient). For education and occupational licensing, it is the knowledge, performance, and ethical standards, as well as the cost of permits and licenses that are collectively controlled as to their number, regardless of the competence and willingness of those who wish to compete on price alone in the area being licensed. In regard to labor, economic rent can be created by the existence of mass education, labor laws, state social reproduction supports, democracy, guilds, and labor unions (e.g., higher pay for some workers, where collective action creates a scarcity of such workers, as opposed to an ideal condition where labor competes with other factors of production on price alone). For most other production, including agriculture and extraction, economic rent is due to a scarcity (uneven distribution) of natural resources (e.g., land, oil, or minerals).

When economic rent is privatized, the recipient of economic rent is referred to as a rentier.

By contrast, in production theory, if there is no exclusivity and there is perfect competition, there are no economic rents, as competition drives prices down to their floor.[2][3]

Economic rent is different from other unearned and passive income, including contract rent. This distinction has important implications for public revenue and tax policy.[4][5][6] As long as there is sufficient accounting profit, governments can collect a portion of economic rent for the purpose of public finance. For example, economic rent can be collected by a government as royalties or extraction fees in the case of resources such as minerals and oil and gas.

Historically, theories of rent have typically applied to rent received by different factor owners within a single economy. Hossein Mahdavy was the first to introduce the concept of "external rent", whereby one economy received rent from other economies.[7]
