Nonetheless, experimental monetary policies in advanced economies – such as the large-scale asset purchases initiated this month by the European Central Bank – have slowed the vicious circle of subpar economic performance and muddled politics. But it is far from clear that this will continue, especially given the US Federal Reserve's gradual exit from such policies, which puts America on a different path from most of the other advanced economies.
然而，发达经济体实验性的货币政策——比方说欧洲央行（ECB）本月发起的大规模资产购买计划——已经延缓了经济表现欠佳和政治混乱等恶性循环的脚步。但鉴于美联储逐步退出刺激计划导致美国所走道路与多数发达国家不同，上述状况能否持续依然是个谜。
