The US could legislate a pre-announced path of slow but steady increases in energy or carbon taxes (accompanied by immediate short-term offsets, such as a reduction in the distortionary payroll tax or an end to the damaging spending sequester). As in Japan, such measures would enhance long-run fiscal sustainability without weakening demand at a time when the economy has not yet fully recovered from the Great Recession.
其他国家的政策有一些有用的类比。美国会立法去预先宣布一项缓慢但稳定的能源或碳税增加路径（同时伴随一些立刻实施的短期补偿，如降低扭曲性的工资税或结束破坏性的支出扣押）。在日本，这些措施能提高长期财政可持续性且不会在经济尚未完全从大萧条中恢复过来的时候削弱需求。
