Holland's Learning Classifier System is based on the application of a simulated economic system to a simulated evolutionary system. The system is basically a production system with evolving rules which "pay" each other, with the root source of income being the external reward signal from the environment, and reproductive opportunities based on accrued wealth. As such, it can be thought of as a simulation of the real economy.
The original LCS doesn't consistently work. An optimum strategy is often found, but then it is lost again as cheaters and over-general rules take over the population and cause the network of optimal rules to collapse. XCS (Accuracy-based Classifier System) is an improvement to this system which doesn't suffer from the collapses of LCS. In this system, rather than accumulating a "bank" and "paying" other rules for their activation, the system works using the Reinforcement Learning paradigm, where each rule's quality measure is adjusted to match the quality measure of the other rules that rely on it, with a bias towards consistency/accuracy of this signal over time. I like to think of the economy as a (crudely effective) learning algorithm, designed to coordinate behavior to mutual benefit of the participants. I wonder if our economic system could benefit from this analogy. Could we put together a system for measuring the "beneficence" (net positive contribution to society at large) of each person, based on social feedback, and then tie the availability of resources/services to this measure, thereby entraining rational self interest under rational shared interest? It could be argued that money already does this, but does a bad job of it for reasons comparable to why LCS isn't reliable. Maybe treating the economy as a multi-component Reinforcement Learning problem is the way to go.
