Imitation:
This is a simplified cultural learning story in which individuals observe what others do and imitate those that are more successful. The specific type of imitation matters so we first need to investigate which type of imitation or learning rule has good properties. Then we can move on to make predictions. It turns out that the underlying dynamics is the replicator dynamics encountered above.References:

The classical approach is to assume rationality. Players correctly anticipate what others are doing and in equilibrium none of the players has an incentive to deviate when assuming that none of the others deviate.
But do we really believe that players have the same beliefs and follow this equilibrium concept? In this lecture we relax these assumptions, do not make heroic assumptions about players think about each other. We assume instead that they learn over time. We investigate what happens in the long run. What will they learn? Will they all do the same thing? Will they learn to play an equilibrium as defined above? Will they sometimes never learn anything as they constantly change their actions?
This is the topic of this course.
In very simple games we will investigate what players learn to play. This will of course depend on how they learn. The models of learning highlighted below will be considered.Methodology:
There is some mathematics involved as one has to understand how play in the population changes over time. However, emphasis will be on understanding intuition in simple settings, and analysis of examples, not proving theorems nor proving general results. Notes are supplied as often the original papers too mathematical.Specific Models
Evolutionary Learning:
This is a simplified biological story in which there are only two types of players, incumbants and mutants. Those that are more successful reproduce. Search is for an evolutionarily stable strategy. In an extended version there are many types and one considers change of play according to the replicator dynamics.
