Because the eurozone lacks a strong central governing body, crisis policies emerge from a political process in which each of the 19 member states has veto power. For such a complex system to work, eurozone policymakers must be able to trust one another to behave in a particular way – and that requires a common framework of rules and standards.
但债务纾困不是答案还有另一个原因，即欧洲货币联盟的政治结构。由于欧元区缺少强有力的中央治理机构，危机政策由一个所有19个成员国都拥有否决权的政治进程决定。要让如此复杂的系统起作用，欧元区决策者必须能够相信彼此以特定方式行事——而这有需要共同规则和标准框架。
