Economic Rent
The surplus payment to a factor of production above what is needed to keep it in its current use. In land economics, rent accrues to landowners purely from locational advantage, not from their own effort.
Definition
In economics, rent in its technical sense is distinct from the colloquial meaning of a lease payment. Economic rent is the payment to any factor of production in excess of what is required to bring it into — or keep it in — its current use. This surplus arises not from the recipient's effort or investment but from some structural advantage, typically scarcity or privileged location.
For land, rent takes on special significance because land is not produced: it was not manufactured, and its supply cannot meaningfully be increased in response to price. The rent of a parcel therefore represents payment purely for its location and natural attributes, which are created by nature and society, not by the landowner.
Ricardo's Law of Rent
David Ricardo formalised the analysis of land rent in his Principles of Political Economy and Taxation (1817). He observed that in agriculture, different plots of land have different natural fertility. Farmers on superior land can produce more output from the same inputs than those on inferior land. In a competitive market, the price of agricultural produce is set at the cost of production on the least productive (marginal) land in use. Farmers on better land earn a surplus above this margin — that surplus is rent, and it accrues to the landlord, not to the farmer's labour or capital.
Ricardo's insight: rent is a differential surplus determined at the margin of production. As population grows and cultivation extends to less fertile land, rents on better land rise automatically — not because landlords do anything, but because the margin shifts.
George's Extension
Henry George extended Ricardo's analysis from agriculture to the urban economy and generalised it to all natural resources. George argued that the same mechanism operates in cities: land near economic activity — ports, railways, markets — commands a location premium. As the economy grows, this location premium (rent) rises. But wages and returns to capital are determined at the margin of production, where land is free. Therefore, as the economy develops, the gains of progress flow disproportionately to landowners, while the position of wage-earners relative to subsistence remains static or worsens.
This is the argument at the heart of Progress and Poverty — and it explains the title's paradox.
Rent-Seeking
A related modern concept is rent-seeking (coined by Gordon Tullock, 1967; named by Anne Krueger, 1974): the use of political or economic power to capture existing wealth rather than create new value. While the term extends beyond land, its intellectual roots are in the analysis of land rent — efforts to extract value rather than produce it.
