摘要

2020年3月,美联储(Fed)主席杰伊·鲍威尔(Jay Powell)面临着一个令人生畏的前景:美联储资产负债表的大规模扩张,而就在几个月前,这个前景似乎还遥不可及。在过去的五年里,经济经历了稳定的增长,这使得美联储能够缩减其资产负债表。美联储的经济学家预计这一趋势将持续下去。但迅速蔓延的全球冠状病毒大流行(被称为COVID-19)使所有先前的预测都变得毫无意义。除了健康危机,美国——以及全世界——在走出大萧条以来最大的经济衰退仅仅10年之后,面临着另一场经济危机的前景。鲍威尔和其他负责财政政策的官员应该如何应对这场危机?为应对2008年大衰退(Great Recession)而实施的政策实验,在多大程度上可以指导应对大流行危机的货币和财政政策干预?对现代经济危机的政策回应2020年3月,美联储主席杰伊·鲍威尔(Jay Powell)面临着一个令人生畏的前景:美联储资产负债表的大规模扩张,而就在几个月前,这种可能性还很遥远。在过去的五年里,经济经历了稳定的增长,这使得美联储能够缩减其资产负债表(见图1的货币基础)。美联储的经济学家预计这一趋势将持续下去。但迅速蔓延的全球冠状病毒大流行(被称为COVID-19)使所有先前的预测都变得毫无意义。除了健康危机,美国——以及全世界——在走出大萧条以来最大的经济衰退仅仅10年之后,面临着另一场经济危机的前景。鲍威尔和其他负责财政政策的官员应该如何应对这场危机?为应对2008年大衰退(Great Recession)而实施的政策实验,在多大程度上可以指导应对大流行危机的货币和财政政策干预?作为经济危机的特征,2008年的全球金融危机出人意料,迫使政策制定者适应不断变化的事件。抵押贷款拖欠加速,全国房价指数在2007年初开始下降(表2)。汇丰银行等银行遭受了巨大损失,有些银行申请破产。尽管房地产市场存在问题,但政策制定者最初保持了乐观的前景。3月17日,美联储主席本·伯南克(Ben Bernanke)表示:“我们认为,次级抵押贷款市场的问题对更广泛的房地产市场的影响可能是有限的,我们预计次级抵押贷款市场不会对经济的其他领域或金融体系产生重大溢出效应。”“……

Policy Responses to Modern Economic Crises
In March 2020, Jay Powell, Federal Reserve (Fed) chairperson, faced a daunting prospect that only a few months prior seemed like a remote possibility: massive expansion of the Fed's balance sheet. Over the past five years, the economy had experienced steady economic growth, permitting the Fed to reduce its balance sheet. The Fed's economists expected the trend to continue. But the rapidly spreading global coronavirus pandemic (known as COVID-19) had rendered moot all prior forecasts. In addition to the health crisis, the United States—and the world—faced the prospect of another economic crisis—just over 10 years after emerging from the largest recession since the Great Depression. How should Powell and his counterparts who ran fiscal policy respond to the crisis? And to what extent could the policy experiments implemented in response to the Great Recession of 2008 guide the monetary and fiscal policy interventions in response to the pandemic crisis?
