Published in the Zeitschrift für Volkswirtschaft, Sozialpolitik und Verwaltung, XVIII, pp. 237–270, Lederer’s article examines Austria’s proposed building-tax reform of 1908 and develops an alternative based on differentiated rates by rent level. Its central question is whether tax concessions can stimulate construction and reduce rents rather than simply raise property values. The argument combines tax-incidence analysis, statistical criticism, and housing-policy proposals.
Lederer begins with Austria’s exceptionally heavy combination of state building taxes and provincial and municipal surcharges:
Daraus ergibt sich, daß der Staat und die Verwaltungskörper in Österreich in weit höherem Maße als anderwärts an den Erfolgen der städtischen Boden- und Bauspekulation partizipieren.
English translation: From this it follows that the state and the administrative bodies in Austria participate to a far higher degree than elsewhere in the successes of urban land and building speculation.
This public participation in property income does not mean that taxation falls uniformly on owners. Scarcity sustains central-city rents, whereas peripheral construction remains sensitive to production costs. Distinguishing urban ground rent from returns on building capital, Lederer argues that taxation can obstruct construction, housing improvements, and tenants’ purchasing power. He rejects simply importing Germany’s land-value-increment tax, given Austria’s existing burdens and administrative costs.
The practical criterion for reform is therefore the recovery of building activity:
Deshalb kann man von einer Steuerreform verlangen, daß alles geschehe, um die Bautätigkeit, die gerade durch die jetzigen Steuerverhältnisse in beträchtlicher Weise geschädigt wurde, wieder zu heben.
English translation: Therefore one may demand of a tax reform that everything be done to raise up again the building activity which has been considerably damaged precisely by the present tax conditions.
The government proposes gradual rate reductions and six years of complete exemption for new buildings, replacing twelve years of reduced state taxation. Lederer welcomes deductions encouraging modern amenities but questions the allocation of relief. Concessions to existing central properties do little to expand supply, while new buildings soon return to full taxation. Exemption from local surcharges also threatens provincial and municipal revenues, potentially requiring compensating increases elsewhere.
Eine nähere Betrachtung des Einflusses dieser Bestimmungen auf die Finanzen der Kommunen und Länder liefert dagegen, wie gezeigt werden soll, ein anderes Ergebnis.
English translation: A closer consideration of the influence of these provisions upon the finances of the communes and the crown lands yields, by contrast, as shall be shown, a different result.
Lederer substantiates this objection through counterfactual calculations using Vienna’s building and revenue statistics. Had the proposal operated from 1895, he estimates that net state-tax savings in 1906 would have slightly exceeded three million crowns against gross rents exceeding 267 million. More than four-fifths of the savings would benefit the most built-up districts, while some outer districts would pay more. As rebuilding continued, increased payments from newer buildings would offset state concessions, leaving local authorities with persistent losses. He contrasts temporary urban relief with permanent remission for the lowest house-class tax categories, identifying an agrarian bias.
His alternative concentrates relief on cheaper dwellings, especially where construction costs constitute a larger share of investment than land values. Its distinctive feature is an abrupt discontinuity between tax brackets. In his illustration, rents up to 400 crowns bear a combined tax of 10 percent, while higher rents bear 40 percent. A rent of 400 crowns thus yields 360 after tax, compared with only 300 from a rent of 500. Owners charging between 400 and 600 crowns would benefit from reducing rents to the threshold.
The mechanism makes rent reductions more profitable than retaining higher nominal rents. Lederer expects the enlarged supply of cheaper accommodation to exert pressure below the threshold, while the tax jump discourages subsequent incremental increases. His claim that this arrangement prevents owners from capitalizing the concession is the proposal’s theoretical wager: discontinuous rates would alter incentives directly rather than rely solely on uncertain construction responses.
The concluding discussion considers financing, implementation, and statistical limitations. Cheap dwellings dominate numerically but account for a smaller share of aggregate rental value, suggesting scope for targeted relief. Lederer considers immediate reductions, phased relief for existing buildings with immediate application to new construction, and a less satisfactory compromise retaining government concessions. He acknowledges that outdated statistics make his calculations illustrative rather than a fully costed programme. Local fiscal coordination remains essential, while existing declarations of individual dwellings could support administration.
The article presents taxation as an instrument of housing policy whose distributive consequences depend on institutional design. Lederer ultimately allows that public resources might better support systematic housing provision. If tax reform is chosen, however, relief must reach tenants and encourage construction rather than become a windfall incorporated into property values.
