ABSTRACT
Up to this point in this volume we have considered the productive system in the case in which there was only one product which constituted both the consumption good and also the man-made instrument of production, the capital good. An example of this is the corn economy in which cereal farming is the only process of production, and in which inputs of land, labour, and seed corn produce only one output, namely corn which in turn can be used either for consumption or as an input of seed corn for next year's productive process. We intend now to take one further substantial step towards reality by allowing for the fact that there are many different products in the economy.
