Frank Albert Fetter, The Relations between Rent and Interest

Frank Albert Fetter’s 1904 conference proceedings paper, reprinted in 1977 together with his reply to discussion, proposes a reconstruction of distribution theory through the distinction between current uses and capitalized future income. Its three parts move from criticism of conventional concepts, through rejection of alternative classifications, to a positive theory of rent and capitalization. The reply clarifies the proposal against objections from Hollander, Carver, Taylor, and MacFarlane. Fetter’s central claim is that rent and interest are successive stages in valuation, not separate incomes corresponding to land and manufactured capital.

The opening criticism identifies several incompatible distinctions concealed beneath apparently simple definitions. Economists distinguish rent from interest by the recipient’s social class, by the natural or produced character of the income source, by its supposed relation to production costs, and by its mode of measurement. These distinctions do not necessarily coincide. Treating them as interchangeable produces contrasts that appear objective but actually arise from changes in the theorist’s standpoint.

Differences between rent and interest, that are assumed to arise out of the nature of the two classes of agents, are but the reflection of the changing subjective attitudes of the theorists.

The decisive unnoticed shift concerns measurement. Land is usually described physically, in acres of differing quality, whereas capital is expressed as a monetary principal yielding a percentage return. Consequently, land appears heterogeneous and capital homogeneous. Fetter credits John B. Clark with exposing this confusion: machines differ physically just as land does, while either can be expressed in value units. Differences in maintenance follow the same pattern. A rented agent is preserved in equivalent physical condition; a loan principal is preserved in value. Neither contrast establishes a division between natural and manufactured wealth.

Fetter’s historical account explains how the confusion became plausible. Renting contracts associated with rural property preceded the money loans characteristic of urban commerce. These practices encouraged the alignment of land, landlords, and rent against machines, merchants, and interest. But contractual convenience, rather than economic substance, governed their use. Machines can be rented, and land can be acquired through borrowing. Moreover, maintaining agricultural productivity requires repairs and restoration: the apparent permanence of land does not establish that its income comes exclusively from indestructible natural qualities.

Part II tests whether the older distinctions could nevertheless support coherent classifications. Social classes provide neither sufficient precision nor an impersonal explanation of value. Dividing natural from produced agents is likewise impracticable, since almost every useful object combines natural material with human adaptation.

The designating of an improved field as land or natural agents, and of an improved piece of iron as capital, becomes a purely arbitrary matter.

The remaining alternative defines rent through its supposed exclusion from production costs. Fetter recognizes the critical achievements of Hobson’s generalization of rent and Marshall’s quasi-rent doctrine, which weaken the exceptional status of land income. Yet extending a surplus or no-cost concept across factors does not explain its relation to interest. MacFarlane’s classification by whether income determines price or is determined by it carries abstraction still further. For Fetter, neither approach supplies a sound, practically usable theory of distribution.

Part III replaces classifications of objects with two perspectives on the same wealth. The wealth aspect considers material agents as bearers of uses; the capital aspect considers their present saleable value. Rent is therefore generalized beyond land to the usufruct of any material agent, with allowance for physical maintenance. Interest belongs to the valuation of income across time.

The capital value of a good is the sum of its prospective rents and uses, discounted at a rate that reflects the prevailing premium on the present.

Capitalization logically follows the estimation of rents: prospective uses must first be identified before their present worth can be calculated. Interest expresses the premium of present over future gratification and can therefore enter the valuation of labor income as well as material income. This universality does not erase differences between wages and rent; it identifies a temporal dimension common to both.

The resulting account organizes value theory around immediately enjoyable goods, durable agents yielding usufructs, and future gratifications discounted to present worth. These are connected phases of analysis rather than independent shares assigned to objectively different productive factors. Fetter thus incorporates marginal utility, rent, and capitalization into one movement from immediate satisfaction to expected future utility.

His reply defends this reconstruction as a substantive change, not merely historical relativism or revised terminology. Against Hollander, he argues that capital’s apparent homogeneity results from capitalization, which can equally be applied to land. Against Carver, he maintains that conserving fertility and bringing marginal land into use also require incentives and waiting. Against MacFarlane, he distinguishes unifying income-bearing wealth from identifying rent with interest, and accepts that foreseeable monopoly income can be capitalized.

The essence of the so-called problem of interest, according to the view in the opening paper is not fundamentally contractual interest, but capitalization.

This final clarification locates the paper’s significance: the problem is not how produced capital earns a separate distributive share, but how future income acquires present value. Fetter even suggests that “the theory of capitalization” would name the inquiry more accurately. His reconstruction preserves differences between uses, principal values, and temporal valuation while rejecting the inherited land–capital division that obscured their relations.
