NonzeroSum TwoPerson Repeated Games with Incomplete
Information
Sergiu Hart
Abstract
Characterization of all equilibria of nonzerosum twoperson repeated games
with incomplete information, in the standard onesided information case.
Informally, each such equilibrium is described by a sequence of
communications between the players (consisting of information transmission
and coordination), leading to some individually rational outcome. Formally,
the concept of a bimartingale is introduced.
