From The Origin of Wealth:
Markets win over command and control, not because of their efficiency at resource allocation in equilibrium, but because of their effectiveness at innovation in disequilibrium.
Evolution, genetic algorithms and complexity theory, as applied to economics: It is a search problem.
This book foretells the demise of economic theories based on equilibrium. To tell the story, a wide path is walked through the history of economics, advanced computer science, physics and some chaos theory. Very interesting reading, if you are interested in economics, or why economics works or doesn’t (quite) work.
