Query: Directional learning and the provisioning of public goods   We consider an environment where players are involved in a public goods game
and must decide repeatedly whether to make an individual contribution or not.
However, players lack strategically relevant information about the game and
about the other players in the population. The resulting behavior of players is
completely uncoupled from such information, and the individual strategy
adjustment dynamics are driven only by reinforcement feedbacks from each
player's own past. We show that the resulting "directional learning" is
sufficient to explain cooperative deviations away from the Nash equilibrium. We
introduce the concept of k-strong equilibria, which nest both the Nash
equilibrium and the Aumann-strong equilibrium as two special cases, and we show
that, together with the parameters of the learning model, the maximal
k-strength of equilibrium determines the stationary distribution. The
provisioning of public goods can be secured even under adverse conditions, as
long as players are sufficiently responsive to the changes in their own payoffs
and adjust their actions accordingly. Substantial levels of public cooperation
can thus be explained without arguments involving selflessness or social
preferences, solely on the basis of uncoordinated directional (mis)learning.
