The paper compares two models of evolution in symmetric twoplayergames with incomplete information. One model postulates thatthe type of a player is fixed, and evolution works within types. Inthe other model type-contingent strategies evolve. In the case of twotypes and two strategies it is...

The paper shows that there is a close connection between (constant)consistent conjectures in a given game and evolutionary stabilityof conjectures. Evolutionarily stable conjectures are consistent andconsistent conjectures are the only interior candidates for evolutionarystability...
