The troika has proved functional, and Europe would have been at pains to provide conditional assistance to eurozone countries without the IMF’s participation and support. But cooperation has proved to be difficult, if only because each participating institution has rules and constraints that are not easy to reconcile with the others’.
除了欧洲的具体情况，三驾马车的实验也回答了世界其他地区的一个重要问题：IMF可以与地区机构合作吗？答案是肯定的，但并不容易。三驾马车功能良好，而若不是IMF的参与和支持，欧洲将难以向欧元区国家提供有条件援助。但合作是艰难的，光是参与机构各自的规则和约束不同且难以互相调和已足够形成阻碍。
