摘要：This paper studies a novel setting
in game theory: a player may learn new actions over time by observing the
opponent's play. We investigate the impact of such learning behavior in the
context of finitely repeated games. In contrast to related literature such as
Kreps et al. (1982), we provide a framework with full rationality and
consistent stage-game payoffs for sustaining cooperation, which bridges the gap
between theories of finitely and infinitely repeated games. Even if rational
cooperation is impossible without learning, for instance in a Prisoner's
Dilemma, it can be sustained with approximate efficiency when players can learn
from one another. Cooperation does not have to be endowed in each player's
initial action set, but can be ``taught'' and enforced. When learning is
imperfect, the set of sustainable payoffs is not continuous, in the sense that
no equilibrium exists when learning is nearly perfect and the repeated games
last for sufficiently many periods.
