在经济和政治问题上的谈判过程，如经济伙伴关系协定（EPA），可能会给参与者带来一种局面，即他们与对手进行多重博弈。这种情况可以被建模为同时重复地与对手进行囚徒困境（PD）博弈和协调博弈（CG）。参考均衡预测和先前的实验结果，我们实验比较了个体和相互合作率在PD时，当被试重复玩只有PD游戏与相同的对手（治疗GD），当他们重复和同时发挥PD和CG与相同的对手在每一轮（治疗GDC）。首先，我们发现，个人合作率在GD治疗高于GDC治疗。第二，在后半轮中，GDC处理的相互合作率高于GD处理。因此，玩CG最初减少了PD中的合作，但在后来的几轮中增加了PD中的相互合作。第一个结果可归因于受试者在GDC治疗中面临比GD治疗更复杂的情况。相比之下，第二个结果可以归因于受试者倾向于在GDC治疗中的游戏之间提供类似的选择。
The bargaining process in economic and political issues such as the Economic Partnership Agreement (EPA) can present players with a situation wherein they engage in multiple games with their counterpart. Such a situation can be modeled as playing a Prisoner’s Dilemma (PD) game and a Coordination Game (CG) simultaneously and repeatedly with the counterpart. Referring to the equilibrium prediction and prior experimental results, we experimentally compared the individual and mutual cooperation rates in the PD when the subjects repeatedly played only the PD game with the identical counterpart (treatment GD) and when they repeatedly and simultaneously played the PD and the CG with the identical counterpart in each round (treatment GDC). First, we found that the individual cooperation rate was higher in the GD treatment than in the GDC treatment. Second, the mutual cooperation rate was higher in the GDC treatment than in the GD treatment in the second half rounds. Thus, playing the CG initially reduced cooperation in the PD but increased mutual cooperation in the PD in the later rounds. The first result could be attributed to the subjects’ facing a more complicated situation in the GDC treatment than the GD treatment. In contrast, the second result could be attributed to the subjects’ tendency to offer similar choices between the games in the GDC treatment.
