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...

We exploit the aggregative structure of the public good modelto provide a simple analysis of the voluntary contribution game. Incontrast to the best response function approach, ours avoids the pro-liferation of dimensions as the number of players is increased, andcan readily analyse games...
