Schwiedland’s critical survey examines investigations of wholesale and retail prices alongside observations of Viennese commerce. Its concern is not simply the difference between purchasing and selling prices, but the mechanisms producing it. Custom, inventories, customer confidence, competition, and capital turnover complicate any inference from wholesale quotations to retail earnings.
The theoretical starting point is Mill’s contrast between competitive wholesale markets and retail prices adapted to particular customers. Schwiedland qualifies this account historically:
Mit dem Entstehen der gewaltigen Schienennetze unserer Zeit und der hierdurch bewirkten modernen Erleichterung des Verkehrs hat jedoch der lokale Monopolkreis, an welchem Mill in seinem letztangeführten Satze gedacht hat, zum Teile aufgehört.
English translation: With the emergence of the immense railway networks of our time and the modern facilitation of traffic brought about thereby, however, the local monopoly sphere of which Mill was thinking in his last-cited proposition has in part ceased to exist.
Improved transport weakens local protection without making retail competition uniform. Retailers retain advantages through specialties, selection, and established relationships. Selling prices tend to accommodate increases more readily than decreases, but resistance to downward adjustment does not by itself establish excessive profit.
Schwiedland therefore emphasizes statistical method. Geographical correspondence between wheat and bread prices, such as that suggested by Metzler’s French evidence, differs from correspondence over time, when wages and production conditions may change. Comparisons of simultaneous wholesale and retail quotations also overlook inventories acquired earlier. An observed spread is not necessarily the markup actually earned. The relevant purchasing measure must capture the firm’s expenditure:
Die „Einkaufspreise“ stellen dann die gesamte Ausgabe dar, welche die Firma bei Beschaffung des Warenvorrates thatsächlich hatte.
English translation: The "purchase prices" then represent the entire expenditure which the firm actually had in procuring the stock of goods.
Purchase records, stock duration, comparable qualities, and the periods during which prices applied are essential to interpretation. Discussions of raisins, anchovies, and petroleum suggest that apparently contradictory movements may reflect earlier purchases, anticipated shortages, or speculation. Such explanations require investigation with the businesses concerned; price curves are not self-explanatory.
Nevertheless, some comparisons reveal striking retail rigidity. In one example, the selling price remains substantially higher despite a pronounced decline in the purchasing price:
Derselbe beträgt sonach bei einem Einkaufspreis von 150—160 im Juli 1880: 250, und zwei Jahre nachher, bei einem Einkaufspreise von 85—110, anhaltend 350.
English translation: It accordingly amounts, at a purchase price of 150—160 in July 1880, to 250, and two years afterwards, at a purchase price of 85—110, persistently to 350.
The significance of this divergence depends on the commodity and transaction. Frequently purchased staples have conspicuous prices and rapid turnover; low margins can attract customers who also purchase less competitive goods. Specialties and purchases made on trust allow greater markups, while luxury goods involve risks of fashion and unsold stock. Small transactions impose disproportionately high distribution costs. Poor households may therefore pay relatively more even though the largest percentage markups occur on luxuries. Percentage margins must also be distinguished from absolute earnings, and coin denominations can obstruct reductions in very small prices.
The sectoral discussions qualify universal explanations. Bread weights can conceal effective price differences, while confidence in meat quality discourages customers from changing suppliers. Schwiedland rejects exaggerated estimates of bakers’ profits and notes that quality changes and declining by-product values complicate meat-price comparisons. Viennese coal supplies a counterexample to easy upward adjustment: competition could prevent retailers from passing on increased costs. Market halls offer advantages by reducing expenses and facilitating sales.
Consumer cooperatives likewise show that organizational form matters. Purchasing scale, stable membership, and cash payment can favor lower prices, but dividend policies can preserve selling margins. Schwiedland contrasts the dividend-paying First Vienna Consumer Association with the cheaper Wiener Hausfrauenverein. Neither provides a straightforward benchmark for independent shops buying through additional intermediaries.
The closing arguments connect these findings to theories of income and monetary change. Against Lexis’s emphasis on remuneration for personal service, Schwiedland stresses entrepreneurial organization and command of commercial relationships. Against Scharling, he distinguishes proportional from absolute price reductions: unchanged distribution costs can prevent an equal percentage decline without preventing an equal absolute decline. His contribution is thus methodological as well as explanatory. Rather than deriving a general price law, he identifies heterogeneous price-forming forces and shows why statistical differences require reconstruction of commercial practice.
