ABSTRACT
Trade. Commerce. Market specialization. Such pursuits are almost as old as humanity itself. We know that Stone Age villagers exchanged food, tools, and services with one another. Surplus of supply and the resultant bartering is a key to advancing economic activity. Human beings are creatures of needs and wants. Once Fisherman X could supply Farmer Y, the earliest economic network was born. Task specialization was encouraged by a natural process-one was a better fi sherman, another, a better hunter.
