Many centrists agree that an optimal fiscal policy would feature short-term stimulus, a multi-year medium-term deficit reduction plan, and measures to reduce long-term liabilities, especially if retrenchment protected growth-oriented public-sector investments. But that is difficult to achieve in a context of deleveraging and fixation on debt.
政治极化是另一个不确定之源。许多中间派同意，最优的财政政策特征应是短期刺激、多年中期赤字削减极化以及削减长期负债的措施，特别是在节约保护增长导向公共部门投资的情况下。但在去杠杆化和修正债务问题的环境下，这很难实现。
