Capital Goods Can Only Be Used If Corresponding Quantities of Consumer Goods Are Fed into the Production Process to Sustain the Laborers Who Work with These Capital Goods

Strigl builds his theory of the macroeconomy on an original account of the part played by different forms of capital. In particular, he stresses the fundamental role that consumer goods, or means of subsistence, play in connection with the fact that production takes time. When consumer goods are used to sustain laborers engaged in time-consuming roundabout production processes, they are used as “free capital.” Since without sustenance for laborers no such roundabout production processes can be started at all, consumer-goods-used-as-capital are the most fundamental or “originary form” of capital.

This fundamental insight, that productively-used consumer goods are originary capital, had already been expressed in Jevons's wage-fund theory of capital, and it is still common stock in Austrian economics. However, no one has surpassed Strigl in systematically analyzing the implications thereof, and in integrating these findings into a theory of the macroeconomy. His legacy to present day capital theorists rests to a great extent mainly on this contribution.

One important implication of this insight is that it is unwarranted to conceive of capital from a purely technological point of view. Machines, buildings, etc.—that is, those capital goods most readily identified with the notion of capital—are themselves products of previous production processes which, ultimately, make use of labor, land, and “productively-used” consumer goods. Moreover, capital goods can only be used if corresponding quantities of consumer goods are fed into the production process to sustain the laborers who work with these capital goods. Using capital goods in production processes and supporting these processes with consumer goods are nothing but two aspects of “one and the same process.”  In short, the quantities and qualities of capital goods in use at any time depend ultimately on what people choose to do with the consumer goods they control. A man can choose to use all his consumer goods in “pure consumption” or to use a part of them (his “savings”) in “productive consumption”; that is, he can use this part to sustain himself or others while being engaged in a productive venture. Depending on such choices, consumer goods become either pure consumer goods or originary capital. Hence, whether one and the same physical object is capital depends ultimately on the choices of the market participants; capital formation has a subjective basis.
