Rick Bookstaber: Human Complexity & Financial Markets

Found via Simoleon Sense.

In a recent post I discuss the limitations of neoclassical economics and the strain of behavioral economics that remains tethered to it. I argue that they fail because the market is inhabited by people, heterogeneous and context-sensitive, who do not live up to the lofty assumptions of mathematical optimization and Aristotelian logic that underlie these approaches – and do not do so for good reasons.

The nature of complexity also is different in the economic realm from that in physical systems because it can stem from people gaming, from changing the rules and assumptions of the system. Ironically, "game theory" is not suited to addressing this source of complexity. But military theory is.
