Observable Contracts: Strategic Delegation and Cooperation
研究玩家通过代理人进行战略委托的博弈，证明当委托契约是共同知识时，任何帕累托最优结果都能成为子博弈完美纳什均衡，并以古诺双寡头模型为例说明。
The role of commitments in noncooperative games is well acknowledged and documented. One way to achieve commitments is by letting delegates represent the players of a game. In this paper, the authors study a delegation game in which the players can use agents strategically to play on their behalf and the contracts they sign with them are common knowledge. They show that, in such cases, every Pareto optimal outcome of the game can become the unique subgame perfect Nash equilibrium of the delegation game. The authors demonstrate this result by discussing the Cournot-type duopolistic game.
