Carl Menger, Neue Untersuchungen über die Theorie der Handelspolitik (1905)

Carl Menger’s review of Richard Schüller’s Schutzzoll und Freihandel examines how differences in enterprises’ production conditions can explain the possibilities and limits of tariff negotiation. Reciprocal concessions, on this account, may benefit both countries without sacrificing entire domestic industries. Menger moves from trade theory’s declining influence on policy to Schüller’s analysis of costs and its implications for commercial treaties. His favorable assessment remains qualified by the need for restrictions and modifications.

The historical opening establishes the practical significance once possessed by economic theory:

Wissenschaftliche Untersuchungen auf dem Gebiete der Handelspolitik haben jahrhundertelang einen maßgebenden Einfluß auf die praktische Tätigkeit der Staatsmänner geübt.

English translation: For centuries scientific investigations in the field of commercial policy exercised a decisive influence upon the practical activity of statesmen.

Menger contrasts the formative influence of earlier doctrines with economics’ subsequent tendency to follow developments in policy. New protective arrangements, larger customs territories, and improvements in treaty negotiation had entered economic discussion, but their inclusion did not establish theoretical leadership:

Ihre Rolle war in diesen Rücksichten indes keine führende; sie hat die obigen Gedanken im wesentlichen der Praxis entlehnt, sie aus der letzteren in die Wissenschaft übernommen.

English translation: Its role in these respects was, however, not a leading one; it borrowed the above ideas essentially from practice, taking them over from the latter into science.

Schüller’s contribution, as Menger presents it, is to investigate the economic conditions underlying such practical developments. The decisive analytical move is to stop treating industries as homogeneous units. Average costs, or exclusive attention to the strongest or weakest enterprises, obscure the internal differences that shape the effects of foreign competition.

Nun lehre aber die Erfahrung, daß sich schwächere Unternehmungen unter Umständen auch dauernd neben stärkeren behaupten.

English translation: Now experience, he says, teaches that weaker enterprises may under certain circumstances also maintain themselves permanently alongside stronger ones.

This observation challenges the assumption that competition necessarily eliminates every higher-cost producer. Theory already acknowledges persistent differences in agriculture and mining; Schüller extends the argument to manufacturing. Menger recounts evidence from sugar factories, linen spinning, and sawmills to show that comparable goods can be produced enduringly at unequal costs within one customs territory. The significance of these examples lies in the persistence of differentiated production conditions, not merely in temporary competitive disadvantages.

A related argument concerns the limits of expansion. Increasing output may spread overhead expenses, but it need not continuously reduce unit costs. Enterprises can exhaust favorable conditions and encounter more expensive materials, labor, or managerial requirements. Additional production may consequently cost more than existing output. Together, persistent differences among firms and limits to low-cost expansion explain why the strongest producers need not absorb an entire market.

These propositions change the interpretation of tariff concessions. A measured reduction in protection may disable only the weakest domestic enterprises or cause some firms to contract production. It need not destroy the industry as a whole, nor exclude new enterprises operating under favorable conditions. Foreign exporters also encounter limits to expansion. The relevant question is therefore how competition redistributes production within industries, rather than whether each national industry survives or disappears.

Reciprocity builds on this differentiated adjustment. A concession imposing limited domestic losses may create substantial export opportunities for the negotiating partner. In exchange, improved access abroad may preserve or expand the first country’s export industries and agriculture sufficiently to outweigh its losses. Differences in the distribution of production costs make mutually advantageous exchanges possible.

Menger thus presents treaty negotiation as potentially beneficial to both parties, rather than necessarily a struggle to impose one country’s losses for another’s gain. This possibility is conditional on the selection and scale of concessions. Governments must assess particular branches of production in both economies instead of relying on an undifferentiated judgment about national competitiveness.

The review’s theoretical significance lies in connecting industrial structure with practical commercial policy. Menger values Schüller’s attempt to explain negotiating practice while specifying the limits of arguments for protection and free trade. The resulting framework replaces an all-or-nothing view of industries with attention to heterogeneous enterprises, constrained expansion, and the reciprocal adjustment of market access.
