Julius Friedrich Gans von Ludassy: Review of Robert Zuckerkandl’s Zur Theorie des Preises mit besonderer Berücksichtigung der geschichtlichen Entwicklung der Lehre (1890)

Julius Friedrich Gans von Ludassy’s 1890 review combines appreciative evaluation with a reconstruction of Zuckerkandl’s argument. He praises the conjunction of historical scholarship and theoretical analysis, emphasizing the breadth of the book’s treatment of economic doctrines:

Von den ersten lallenden Versuchen bis zu den jüngsten entschiedenen Thaten entgeht diesem überaus belesenen Schriftsteller keine Phase.

English translation: From the first stammering attempts to the most recent decisive achievements, no phase escapes this exceedingly well-read writer.

The review proceeds from economic method through the distinction between value and price to marginal utility, productive inputs, and exchange. Its central concern is how price theory can recover the subjective judgments and concrete circumstances obscured by overly abstract accounts of market behavior.

The methodological opening criticizes English economics for generalizing from transactions governed by strictly self-interested calculation. Assumptions of mobile capital, informed entrepreneurs, unrestricted occupational choice, and expandable production secure precision by excluding important conditions of economic action:

In dieser Art vereinfachte die Lehre widernatürlich die Wirklichkeit und gelangte zu Sätzen, welche wohl nichts an Klarheit und Bestimmtheit zu wünschen übrig liessen, aber den thatsächlichen Vorkommnissen nicht entsprachen.

English translation: In this manner the doctrine simplified reality in a manner contrary to nature and arrived at propositions which indeed left nothing to be desired in clarity and definiteness, but did not correspond to the actual occurrences.

German demands for closer observation provide a necessary correction. Yet criticism of defective deductions does not justify rejecting deduction itself. Historical research and descriptions of contemporary conditions cannot replace explanation. Theory remains possible because economic phenomena exhibit recurring patterns grounded in persistent psychological forces.

The history of doctrine supports this enterprise by clarifying the concepts through which exchange has been understood:

Zuckerkandl legt dar, in welcher Art sich die ursprünglich ununterschiedene Bedeutung der Bezeichnung Werth und Preis im Laufe der Zeit immer mehr differenzierte und untersucht zu diesem Behufe den Sprachgebrauch bei älteren Autoren.

English translation: Zuckerkandl sets out the manner in which the originally undifferentiated meaning of the terms value and price became ever more differentiated in the course of time, and to this end he examines the linguistic usage of older authors.

The decisive analytical move is to begin with relations between people and goods rather than quantitative exchange ratios. Explanations become mechanical when external quantities displace the judgments through which goods acquire economic significance.

Ludassy presents Menger’s subjective value theory as a culmination of this development while attending to Zuckerkandl’s modifications. Dependence on goods for satisfying needs entails both willingness to sacrifice something to obtain them and demands for compensation when surrendering them. Against Böhm-Bawerk’s separation of subjective value from objective exchange value, Zuckerkandl seeks to connect valuation with purchasing power. Nevertheless, a market price cannot directly disclose any particular person’s valuation.

This distinction also informs the treatment of supply and demand. Quantities alone do not explain prices; the motives determining transactions must enter the account. Familiar propositions about production costs and changes in supply or demand offer starting points rather than a complete theory. Explanation must address relatively stable prices, persistent differences between goods, and the prices of important commodities and labor. Since exhaustive enumeration of causes is impracticable, inquiry should group comparable cases and investigate ordinary conduct: participants neither calculate with perfect knowledge nor wholly disregard their interests.

The account of marginal utility follows Menger and Wieser in relating the value of a unit within a stock to the least important satisfaction that the stock still secures. This explains how goods of great general usefulness can possess little value. Its application nevertheless encounters misjudged utility, diverse preferences, and the absence of a universally valid ranking of needs. Unequal incomes prevent money prices from serving as uniform measures of subjective valuation. As goods become more abundant, poorer buyers’ valuations acquire greater importance.

Production presents a related difficulty. Where several indispensable inputs jointly produce an output, the output’s value establishes their aggregate value without independently determining each input’s share. Subjective valuation therefore does not automatically resolve every problem of attribution.

Finally, exchange becomes intelligible through unequal valuations: each participant prefers what is received to what is surrendered. With multiple buyers and sellers, their judgments establish limits within which transactions can occur, while economically directed exchange tends to narrow simultaneous price differences. Prices are constrained without becoming direct measures of utility. Ludassy’s favorable assessment presents subjective value theory as an explanatory advance whose development requires attention to imperfect knowledge, purchasing power, and the concrete conditions of exchange.
