Geo-Rent: A Plea to Public Economists (Foldvary, 2005)

Summary

"Geo-Rent: A Plea to Public Economists," by Fred E. Foldvary, appeared in Econ Journal Watch 2(1): 106–132, April 2005. Foldvary coins geo-rent — what an unimproved plot would rent for at auction — and argues that public economics, despite scattered pieces of the analysis appearing across eight standard microeconomics and public-finance topics, has never assembled them into a coherent recognition of land rent's fiscal importance. The paper's own summary states the thesis directly: "the shunting aside and disparagement of public revenue from geo-rent has distorted economic analysis and contributes to iatrogenic economy-hampering fiscal policy."

The Eight Compartments

Foldvary surveys eight mainstream topics where geo-rent principles already surface in the textbook literature, but remain "compartmentalized" rather than connected: producer surplus, deadweight-loss analysis, the Henry George Theorem, capitalization, public goods, externalities, club-good models, and the Tiebout model. Two of these carry the paper's sharpest claims:

• Producer surplus is mostly geo-rent in disguise. Every microeconomics textbook draws "producer surplus" as the area between the supply curve and price, but — following David Friedman (1996) as a rare exception — Foldvary asks who actually receives it. In a fully competitive model, firms earn no economic profit and competitive factor markets pay labor and capital their marginal products, leaving nowhere else for the surplus to flow except to the fixed factor, land: "producer surplus does not go to producers at all; it is a payment to landowners who have never produced a thing. It is really the non-producer surplus."
• Deadweight-loss analysis already proves the case, but doesn't apply it. Textbooks teach that a tax on a perfectly inelastic supply has zero excess burden, and some note that land's fixed supply makes it a candidate — but, Foldvary observes, few mention that Adam Smith and John Stuart Mill both proposed exactly this, and public-finance textbooks rarely connect the elasticity lesson to policy at all.

The Revenue Estimate

Foldvary surveys prior estimates of land rent's scale — Steven Cord's roughly 20% of GDP, Mike Miles's comparable independent figure, and Tideman, Plassmann & Edenhofer's (2002) projection that shifting taxation to capture 90% of land rent would net $1.3 trillion (14% of NDP) in 2002, rising to $4.8 trillion (26.6% of NDP) by 2042 — against the fixed-supply efficiency argument (a revenue-neutral shift to land value taxation, at an assumed land-capital elasticity of substitution of 0.5, raises capital goods 122% and output 89% in Tideman et al.'s model). Weighing this evidence, Foldvary concludes the tax base is "substantial, most likely in the range of 50 percent of all-level government tax revenues" — the origin of the "roughly half" figure the wiki's Foldvary bio page already cites. He contrasts this with the official U.S. national accounts, where the only line item called "rent" ("rental income of persons") was $150 billion in 2004, under 1.5% of GDP — evidence, in his reading, of how thoroughly geo-rent is undercounted by measuring only its narrowest, most visible slice rather than the land-rent embedded throughout the economy's capitalized values.

Capitalization as a Government Incentive Mechanism

Foldvary extends the Henry George Theorem into an incentive argument: if local government captures 50% of geo-rent through taxation and spends it on infrastructure and security that in turn raise geo-rent further, government becomes a "half residual claimant" on the value its own spending creates — the same residual-claimancy logic that, in his other work, explains why private communities and condominium associations can finance collective goods from assessments alone. Under the status quo, by contrast, public works are financed mostly from taxes on labor, profits, sales, and non-land property, while landowners "receive an implicit subsidy" from public investment they did not pay to create — a claim closely paired with the wiki's existing public investment capitalizes into land page.

A Worked Transition Schedule

The paper includes an illustrative 20-year phase-in schedule for shifting from conventional property tax to full geo-rent capture: starting from the ~25% of geo-rent already implicit in a 2%-of-land-value property tax (at a 6% capitalization rate), the landowner's share rises 5 percentage points a year — 30% in year 11, 50% by year 15, 75% by year 20 and thereafter — offered "if only to serve as a conceptual model" for how a transition might be sequenced to avoid an abrupt shock, rather than as a specific policy recommendation.

Relation to the Georgist Case

This is a direct, explicit restatement of the classical Georgist revenue argument by a professional economist in a peer-reviewed, open-access, editorially refereed venue — not a new empirical finding, but a synthesis making the case that the pieces of the argument already exist scattered across mainstream economics and simply need to be connected. Its "producer surplus is non-producer surplus" framing is a sharper, more textbook-native version of the wiki's broader claim (see economic rent and rentier) that much measured "profit" in a competitive economy is actually land rent misattributed to capital or entrepreneurship.

Nuances and Limits

• The 50%-of-revenue estimate is Foldvary's own synthesis judgment, not a single peer-reviewed point estimate — it rests on reconciling several independent but methodologically different studies (Cord, Miles, Tideman et al.), each of which the wiki's other pages already flag as advocacy-adjacent or dependent on how broadly "land rent" is measured. Treat it as a plausible upper-bound synthesis, not a consensus academic figure.
• The transition schedule is explicitly illustrative, not a proposed policy — Foldvary frames it as "a conceptual model," and this page should not be read as attributing a specific transition-timeline recommendation to him.
• Working paper venue. Econ Journal Watch is an editorially refereed, open-access journal specializing in critical commentary on mainstream economics, not a standard double-blind-refereed research journal — appropriate for this paper's synthesis/critique genre, but worth noting for readers calibrating its evidentiary weight.

Bears On

• Person: Fred Foldvary — this paper is one of his core contributions, already summarized on his bio page; this is its dedicated treatment.
• Objection: LVT Doesn't Raise Enough Revenue — Foldvary's ~50%-of-revenue synthesis is one of the more optimistic estimates in this debate, worth reading alongside the more conservative figures the objection page already surveys.
• Concept: Henry George Theorem — the theoretical mechanism (public spending capitalizes into land rent) this paper applies to a revenue-scale argument.
