In this book I am concerned only with productive entezprises and productive entrepreneurs. It hardly needs saying that production includes commercial activities, in so far as they are a link in the chain converting original resources into final goods and services. NARROW VERSUS WIDE TECHNOLOGY The standard neoclassical concept of technology is based on the production function.

As regards the supply of capital, or more Neoclassical Theory 29 accurately of finance, perfect competition would imply that any firm can obtain as much as it desires at the 'going' rate. Under these conditions, there would be no role for the entrepreneur as a supplier of capital.

Excess demands cannot ever 'exist' in a Walrasian world, because they are inconsistent with the model. They can only be imagined, as part of a story that tries to give some verisimilitude to the model. But the model bears no relation to the real world process of decisionmaking. Even in a world without production time lags, the model makes no sense. For, in such a world, every transaction would represent a position of equality between supply and demand. There would never be any 'excess demand'. The solution of a Walrasian system of simultaneous equations has created some problems for mathematical economists, and they have had an even greater problem in trying to prove that the auctioneering process will eventually lead to a general equilibrium.
