Information, interaction and memory

Abstract

This paper extends previous work on evolutionary games by introducing non-trivial memory into a model where information flows and interactions are captured using networks, as in Alós-Ferrer and Weidenholzer (J Econ Theory 143:251– 274, 2008). We consider two-player K × K coordination games and analyze best response dynamics as well as imitation dynamics. We show that for any arbitrary information network, including those with asymmetric information exchanges, the introduction of non-trivial memory corroborates the results of previous studies: with best response, agents select the ½ -dominant strategy while imitators favor efficiency. Furthermore, we expose the sensitivity of the efficiency results to the interaction patterns.
