Moreover, by pushing interest rates toward zero, the current policy of quantitative easing (increasing money supply by buying government securities) has strong, often regressive, income effects. Opponents of central-bank independence contend that, given the allocational and distributional consequences of current monetary-policy interventions, central banks’ decision-making should be subject to political control.
这一变化——转向多重政策目标——难免会削弱央行独立性。一些分析师最近声称这是因为追求GDP增长、就业创造、金融稳定以及在存在权衡时决定孰先孰后显然要求政治决策，而政治决策不应该光由非民选官员做出。此外，通过将利率推向零水平，当前的量化宽松政策（通过购买政府证券增加货币供给）具有相当强的、通常是累退的收入效应。央行独立的反对者指出，由于当前货币政策干预的配置和分配后果，央行决策应该受政治控制。
