public class ZIPExperiment

extends MarketSimulation

An implementation of Cliff's symetric supply and demand ZIP experiment. See:

"Minimal Intelligence Agents for Bargaining Behaviours in Market-based Environments" Dave Cliff 1997

Work is currently in progress to attempt a full replication of the results in the above paper. Currently JASA is not able to replicate these results.
