Simulation attempts to show why the rich get richer in unregulated markets.:

This is a simulation of an economic marketplace in which there is a population of actors, each of which has a level of wealth (a single number) that changes over time.

Interesting work that reminds me of story about Milton Friedman’s grad students playing monopoly and modifying the rules to see how it changes outcome. They actually worked out a redistribution system that keeps people in the game by taxing wealthy players when they pass go and putting that money in free parking. The poorest players would then get a cut from free parking. That change kept the game going much longer then it normally would.
