CHAPTER X

THE REAL COSTS OF PRODUCTION

§1. _Comparative Costs_. Beneath the great diversity of the considerations which are applicable to the different agents of production, certain general conclusions emerge from the analysis of the last four chapters. In no case did we find that the aggregate supply of the agent was determined by clear and certain economic laws, possessing any fundamental significance. The supply of natural resources is a fixed thing, quite independent of the efforts or the desires of man. However the supply of capital and the supply of labor may react under present conditions towards economic stimuli, these reactions possess no quality of inevitability and bear no clear relation to "what should be." The supply of risk-bearing responds perhaps more decidedly to the prospects of increased reward; but it is so intimately associated with special knowledge and the qualities of business enterprise, as to leave some uncertainty attaching even to this conclusion. When, on the other hand, we turn to the apportionment of these factors among different uses, we find relations which are both clear and fundamental. Laws emerge which state at once not only "what is" or at least "what tends to be," but also "what should be"; and it is the fact that they taste "what should be" that gives them their fundamental character.

These conclusions enable us to give a general answer to the question which was raised at the end of
