Stability and Cooperative Solution in Stochastic Games

Cooperative game theory is effective in explaining many economic interactions, such as risk-sharing agreements or the enforcing role of social norms. In a stochastic environ- ment, the analysis of these issues is generalised by taking into account the presence of shocks. The paper finds the conditions of dynamic stability for cooperative stochastic games. Principles of dynamic stability include three conditions: subgame consistency, strategic stability and irrational-behaviour-proof of the cooperative agreement.
