W. Brian Arthur

The Economy as an Evolving Complex System II, edited with Steven Durlauf and David Lane, Addison-Wesley, Reading, Mass., Series in the Sciences of Complexity, 1997

This is a collection of papers that together comprise the modern approach to complexity in economics. They tend to view the economy as a multiagent system, and focus on the economy-in-process, rather than the economy at equilibrium.

Here is the introduction to the book, by Arthur, Durlauf, and Lane. It has much to say about the "Santa Fe approach" to economics.
