Emil Lederer, Bodenspekulation und Wohnungsfrage (1907)

Emil Lederer’s article examines whether land speculation causes high urban rents or follows from them. Comparing Vienna and Berlin and assessing Austrian housing taxation, he challenges the inference that expensive land necessarily explains expensive housing. His starting point is the conjunction of overcrowding and rising land values:

Der auf den Kopf entfallende Wohnraum war erschreckend klein, und andererseits erreichten die Bodenpreise in den Städten, besonders aber an der Peripherie, im Vergleich zu früheren Zeiten eine exorbitante, vorher nicht gekannte Höhe.

English translation: The living space falling to each head was alarmingly small, and on the other hand land prices in the cities, but especially at the periphery, attained, in comparison with earlier times, an exorbitant height previously unknown.

Their coexistence, however, does not establish causal priority. Lederer questions both Eberstadt’s emphasis on speculation supported by planning institutions and Andreas Voigt’s emphasis on construction costs. Neither institutional comparison nor the relative shares of land and building costs alone adequately explains rent formation. Vienna and Berlin are revealing because different land values coexist with broadly comparable housing difficulties.

The Austrian house-rent tax provides a test of competing explanations. Drawing on the 1903 building-tax inquiry, Lederer discusses Philippovich’s empirical investigations and Wieser’s theory of tax incidence. Philippovich finds no consistent correspondence between tax changes and rent movements but leaves land-price formation insufficiently explained. Wieser distinguishes taxation of construction capital, which passes to tenants, from taxation of ground rent, which falls on owners. Lederer questions the assumptions that peripheral land prices cannot fall below an agricultural minimum and that central ground rents have already reached their maximum. The evidence resists a uniform account:

Es können keine allgemeinen Wirkungen einer Steuermaßregel konstatiert werden, diese sind vielmehr nach den einzelnen Straßen und Gebäudegruppen sehr verschieden.

English translation: No general effects of a fiscal measure can be ascertained; these are rather very different according to the individual streets and groups of buildings.

Lederer’s alternative emphasizes historical changes in building production. Multistorey construction and larger building enterprises reduced costs per dwelling. Where rents remained stable, these savings could increase ground rent and its capitalized land value. In Berlin, they supported higher land prices; in Vienna, taxation absorbed much of the surplus before it could become land value. Taxation could thus prevent a speculative asset from arising without making housing cheaper. Low land prices are not themselves evidence of affordable housing.

This argument does not mean that taxes can never restrict construction. Their effects depend on whether the return required to mobilize building capital remains available:

Sollte sich herausstellen, daß infolge der Steuerwirkung die Bautätigkeit gehemmt wird, so könnte das nur darin seinen Grund haben, daß das Baukapital keine ausreichende Verzinsung genießt und infolge dessen zurückgehalten wird.

English translation: Should it turn out that building activity is inhibited in consequence of the effect of the tax, this could have its ground only in the fact that building capital does not enjoy a sufficient return of interest and is consequently held back.

Lederer also distinguishes provincial owners’ complaints about poor returns from metropolitan property economics. Older property valuations could capitalize income at low interest rates, while mortgage borrowing required the higher returns customary for mobile capital. Financial difficulties therefore cannot automatically be attributed to taxation. Inadequate Austrian data qualify his empirical case: comparisons of reported land values, rental income, and estimated building values expose valuations leaving implausibly little income to remunerate construction capital.

The concluding six-part analysis locates high rents in the distinctive organization of housing markets. Drawing on Böhm-Bawerk’s account of complementary productive goods, Lederer treats land as the nonreplaceable factor receiving the residual after reproducible inputs have been paid. Construction economies can consequently accrue to landowners rather than tenants. Slow replacement of existing buildings and inherited price expectations impede rent reductions, while labour-intensive construction and rapid urban concentration intensify pressure on locally produced housing.

Demand is divided by social class, location, building quality, and floor level. These differentiated submarkets permit prices to track tenants’ purchasing power more closely than in markets for standardized necessities. Competition among landlords does not necessarily eliminate this advantage: owners need not discount vacant dwellings to attract poorer tenants, and each property’s fixed capacity limits the additional business obtainable through price reductions.

Finally, housing consumption is relatively indivisible. Moving is costly, alternatives are restricted, and households cannot reduce consumption through small adjustments. The need to secure an indispensable dwelling weakens tenants’ bargaining position. Lederer thus reverses the conventional causal account: high rents generate ground rent and land prices, furnishing speculation with its object. He explains housing hardship through durable supply, segmented demand, limited competition, and essential consumption, while leaving open how far administrative intervention could remedy these conditions within the existing social order.
