While theoretical arguments can be made to justify recent departures from policy, the reality is that in the post-crisis world, advanced-country central banks’ goals are no longer limited to price stability. In the United States, the Federal Reserve has essentially adopted a quantitative employment target, with nominal GDP targets and other variations under discussion in other countries.
论证最新的政策转向的理论观点不难找，但现实是在后危机时代，发达国家央行的目标不再局限于价格稳定。在美国，美联储事实上采取了量化就业目标，其他国家则在讨论名义GDP目标和其他目标。金融稳定性也再次成为央行的责任，包括较为保守的欧洲央行。
