Why should the Federal Reserve allow long-term interest rates to spike just because other central banks have ceased their dollar-purchase programs? Should not the Fed step in and replace them with its own purchases of long-term US Treasury bonds, thereby keeping long-term interest rates at a level conducive to full employment?
国际金融经济学家描述的这幅图景，国内宏观经济学家却认为更像是货币政策的失误。美联储为什么仅仅由于外国央行停止了美元购买计划就允许长期利率大幅增长？美联储就不能介入其中，自己购买美国发行的长期债券，从而把长期利率控制在有利于扩大就业的水平？
