到那时，希腊将恢复经济增长，实现基本的财政盈余(比如，它的税收所得将比开支多，息前)，欧盟和国际货币基金组织的经济学家断言。

At that point, claim the EU's and IMF's economists, Greece will have returned to growth and reached a primary budget surplus (ie, it will raise more revenue than it spends, before interest).

但是，据斯蒂格利茨，在信息不对称的世界中，“良好的行为是由赚取高于他处所得的盈余所推动的”。

But in a world of information asymmetry, "good behaviour is driven by earning a surplus over what one could get elsewhere," according to Mr Stiglitz.

所以在研究风险模型时对盈余和理赔序列的概率假设就显得至关重要，当它们变化时所得到的风险模型也就不同。

So on the research of claims and surplus of risk models will be crucial, when they changes, the conclusion of the corresponding models will be changed.
