2. The Optimal Size of Establishments on Primary Production and in Transport

The Law of Proportionality in combining the factors of production was first formulated in connection with agricultural production, as the Law of Diminishing Returns. For a long time its general character was misunderstood, and it was regarded as a law of agricultural technique. It was contrasted with a Law of Increasing Returns, which was thought to be valid for industrial production. These errors have since been corrected.1

The Law of the Optimal Combination of the factors of production indicates the most profitable size of the establishment. Net profit is greater according to the degree to which its size permits all factors of production to be employed without residue. In this way alone is to be estimated the superiority which the size of one particular establishment gives it over another establishment — at the given level of productive technique. It was a mistake to think that enlargement of the industrial establishment must always lead to an economy of costs, a mistake of which Marx and his school have been guilty, although occasional remarks betray the fact that he recognized the true state of affairs. For here, too, there is a limit beyond which enlargement of the establishment does not result in a more economical application of the factors of production. In principle, the same may be said of agriculture and mining; the concrete data only differ. It is merely certain peculiarities of the conditions of agricultural production which cause us to regard the Law of Diminishing Returns as primarily affecting land.

The concentration of establishments is primarily concentration in space. As the land suitable to agriculture and forestry extends in space, every effort to enlarge the establishment increases the difficulties that spring from distance. Thus an upper limit is set for the size of the agricultural unit of exploitation. Because agriculture and forestry extend in space it is possible to concentrate the establishment only up to a definite point. It is superfluous to enter into the question — often raised in discussion of this problem — whether large or small scale production is the more economical in agriculture. This has nothing to do with the Law of the Concentration of Establishments. Even supposing large scale production to be superior, one cannot deny that there could be no question of a Law of the Concentration of Establishments in agriculture or forestry. The fact that land is owned on a large scale does not mean that it is worked on a large scale. The great estates are always composed of numerous farms.

This appears even more clearly in a different branch of primary production, mining. Mining enterprise is tied to the place where the ore is found. The establishments are as large as these separate places permit. They can be concentrated only to the degree in which the geographical position of the separate beds of ore make concentration seem profitable. In short, one can see nowhere in primary production any tendency to concentrate productive units. This is equally true of transport.
