This paper provides a genera1 framework to analyze rational learning in strategic situations where the players have private information and update their private priors collecting data through optimal experimentation. The theory of statistica1 inference for stochastic processes and of Markovian...

Admissibility, i.e. the deletion of weakly dominated strategies, is a highly controversia1 solution concept for non cooperative games. This paper proposes a complete theory of weak dominance and, contrary to almost al1 the literature on this topic, it provides positive results on foundations of...
