This paper analyzes the relations between knowledge, control and organizational structure both in the market system as a whole and in private organizations.

This means that if the knowledge valuable to a particular decision is to be used in making that decision, there must be a system for partitioning out decision rights to individuals who already have the relevant knowledge and abilities or who can acquire or produce them at the lowest cost. Self interest on the part of individual decision-makers means a control system is required to motivate individuals with the decision rights and the relevant knowledge to use those decision rights appropriately. This control problem is solved in a capitalist economy by a system of alienable property rights.
