Although such an approach does not permit exact general results like analytical studies do, it enables us to study complex interactive models which could not be dealt with analytically.
Classifier systems belong to the class of artificial intelligence methods.
Magele, C. A . Money as a medium of exchange in an economy with artificially intelligent agents . The major finding that emerges from all of these studies . A number of researchers have sought to explore this follow up question in the context of the Kiyotaki Wright model using either agent based computer simulations or controlled laboratory studies with paid human subjects, but not both. Therefore , alternative approaches apart from REH which describe agents adaptive behavior, are said to be necessary.
