Hobbled by severe damage to private and public-sector balance sheets, and with policy interest rates at or near zero, post-bubble economies have been mired in a classic “liquidity trap.” They are more focused on paying down massive debt overhangs built up before the crisis than on assuming new debt and boosting aggregate demand.
其中原因并不难理解。由于私营及公共企业的资产负债表受到严重破坏，政策利率又几近为零，后泡沫经济已经陷入了典型的“流动性陷阱”。相对于进一步举债或刺激总需求，人们更加关心如何偿还危机之前积累的巨额债务。
