One possible solution would be to permit member states to issue debt as eurobonds up to, say, 60% of GDP, and to require them to be individually responsible for any debt exceeding that level. This would give countries with high levels of public debt an incentive to consolidate their public finances.
一种可能的解决办法是允许成员国最多发行相当于GDP的60%的欧元债，如果债务超限，就要追究个体国家的责任。这将给公共债务水平较高的国家整固其公共财政的激励。
