### 644-670: Evolutionary Game Theory

A few words on Evolutionary Game Theory:

About a month ago, Michael asked me to give my opinion on an article on cheating viruses and game theory. Coincidentally, I had to write a referee report on a paper about evolutionary game theory (EGT) only recently, so I have collected further material and ideas about this topic which I would like to share with you:Links are omitted, but click through and check out the ways that evolutionary logic is used by economists.

Jörgen Weibull's paper "What have we learned from Evolutionary Game Theory so far?" provides a great non-technical introduction to EGT. It gives a first idea of what EGT is all about. I very much appreciated the reference list of this paper as well. In Evolutionary game dynamic, Josef Hofbauer and Karl Sigmund dig a little deeper and provide some interesting insights into the relationship between systems of differential equations (inclusions) and special equilibrium refinements (notable ESS and ES). Finally, I would like to draw your attention to Daniel Friedman's paper "On economic applications of evolutionary game theory". This paper is also non-technical and its objective is to make the general ideas behind an evolutionary game theoretic model more tranparent. As the title suggests, Friedman gives a nice outline of how these ideas can be incorporated into economic models.
