The G-20 mutual assessment process--a perspective from IMF staff
从IMF工作人员视角回顾G-20相互评估进程的经验，分析其作为协调机制在促进全球需求再平衡中的作用，并指出当前合作条件变化带来的挑战。
In the wake of the financial crisis, G-20 leaders launched a framework to mutually assess their policies to help strengthen the global economy. This article reflects on the experience so far with the Mutual Assessment Process (MAP). It looks at the coordination problem facing G-20 economies with respect to the need for global rebalancing of demand. While a classic ‘coordination failure’ has some appeal, a more compelling case for policy cooperation is based on the role of spillovers and interdependence. In this context, the G-20 MAP—as a coordination vehicle—has the potential to build shared understanding, enhance mutual trust, and galvanize action among members. Simulated gains from collective action are potentially sizeable. However, key conditions that engendered remarkable global cooperation at the height of the crisis are now more diffuse, posing challenges to what the MAP might achieve going forward and providing some initial lessons for international policy coordination.
