Evolution of Cooperation in the Snowdrift Game with Incomplete Information and Heterogeneous Population

We introduce a new variation of the hawk-dove game suggested by an experiment that studies the behavior of a group of domestic fowls when a subgroup has been marked. Speci cally we consider a population formed by two types ...
Replicator Dynamics and Evolutionary Stable Strategies in Heterogeneous Games
(2011-12)
We generalise and extend the work of Iñarra and Laruelle (2011) by studying two person symmetric evolutionary games with two strategies, a heterogenous population with two possible types of individuals and incomplete ...
