摘要：It is shown that, for almost every two-player game with imperfect
monitoring, the conclusions of the classical folk theorem are false. So,
even though these games admit a well-known approximate folk theorem,
an exact folk theorem may only be obtained for a measure zero set of
games.
A complete characterization of the e¡é cient equilibria of almost every
such game is also given, along with an ine¡é ciency result on the imperfect
monitoring prisoner.s dilemma.
