The Meaning of Economic Rent, Various Classifications, Mechanisms, and an Illustration

Economic surplus refers to the excess amount of money earned that surpasses what is economically or socially necessary. This phenomenon occurs in situations where a buyer, striving to acquire an exclusive product or service, makes an offer before learning the acceptable price set by the seller. Imperfections in the market give rise to economic surplus, which would not exist in perfect markets due to competitive forces driving down prices.

Economic surplus should not be mistaken for ordinary profit or surplus that arises during competitive capitalist production. Additionally, it differs from the conventional definition of "rent," which pertains to payments received in exchange for the temporary use of specific goods or properties like land or housing.

Economic surplus can also emerge when certain producers in a competitive market possess asymmetric information or technologically advanced production systems that grant them a competitive advantage as low-cost producers, while others lack the same capability or resources to acquire such advantages.

The accumulation of competitive advantages over time, resulting from economic surplus, often leads to diminished competition and entrenched business practices. As a result, governments and related agencies often seek to update rules and regulations as a reliable means of reducing economic surplus and fostering healthy competition.

In the testimony of Gary Gensler, the chair of the U.S. Securities and Exchange Commission (SEC), presented before the U.S. Senate Committee on Banking, Housing, and Urban Affairs on Oct. 5, 2021, he highlighted the qualities of the U.S. financial system that establish its global leadership. Gensler emphasized the need for updates to SEC rules to keep pace with technological advancements and ensure the utmost efficiency and competitiveness in the markets. This testimony exemplifies the endeavor to strike a balance between current levels of American competitiveness and the aim to mitigate economic surplus.

Scarcity conditions can also give rise to economic surplus and can be used to illustrate several pricing disparities. For instance, unionized workers may receive higher wages compared to their nonunionized counterparts, or star athletes may earn substantial salaries in contrast to average workers.

Moreover, economic surplus elucidates the elevated value of exclusive intangible assets such as patents and permits, collectively known as scarcity rents.

For instance, a worker may be willing to accept a wage of $15 per hour, but due to union membership, they receive $18 per hour for the same job. The additional $3 can be regarded as the worker's economic surplus or unearned income.

In relation to this matter, unearned income pertains to the amount provided that surpasses the perceived value of one's skills and abilities in the current marketplace. It can also occur when an individual's skills would be valued lower in an open market, but they receive higher compensation due to their association with a group, such as a union, that establishes minimum wage standards.

As an alternative example, suppose the owner of a property in an exclusive shopping mall is willing to lease it for $10,000 per month. However, a company eager to secure a retail storefront in the mall offers a monthly rent of $12,000 to prevent competition. In this case, the $2,000 difference represents the owner's economic rent.

Furthermore, unearned income can be observed in scenarios where two properties possess identical features, aside from their locations. If one location is deemed more preferable than the other, the owner of the preferred location receives higher payment without having to engage in additional work. This lack of additional labor on the owner's part also qualifies as unearned income.

Additional manifestations of economic rent include information asymmetries, wherein an agent gains excessive profits by possessing information not disclosed to the principal or the rest of the market.

Contract rent pertains to situations in which two parties reach a mutually agreed-upon arrangement, but external circumstances change over time, leading to unequal benefits for one party, often at the expense of the other.

Monopoly rent refers to the circumstances in which a monopoly producer lacks competition, allowing them to sell goods and services at a significantly higher price than what would be observed in a competitive market. This comes at the expense of consumers.

Differential rent involves the surplus profit that may arise due to variations in land fertility. The difference in surplus between marginal land and intramarginal land constitutes the differential rent. It is typically accrued in conditions of extensive land cultivation.

The concept of differential ground rent was initially introduced by the classical political economist David Ricardo.
