Network industries.

The entry on Competitive Market Theory outlines the economics of the "old world" economy in which demand and supply are mediated through a market mechanism in which product demand is independent of other products and demand is not time dependent. However, there is a class of markets and industries that do not conform to these assumptions. These are known as network industries₁ (see: Networks). Networks are interconnected nodes that enable individual nodes to be linked either in production or in consumption with other nodes. [ABSTRACT FROM AUTHOR]
