日本央行计划在9月评估其货币刺激计划，令市场再度预期它可能采取某种形式的“直升机撒钱”做法，为增加政府支出印钞票。请看本报昨日的报道：

    The Bank of Japan’s review of its monetary stimulus program promised for September has revived expectations it could adopt some form of “helicopter money,” printing money for government spending to spur inflation.

    The BOJ disappointed market hopes Friday that it might increase its heavy buying of government debt or lower already negative interest rates, cementing the view that it is running out of options within its existing policy framework to lift prices and end two decades of deflationary pressure.

    报道中的helicopter money就是“直升机撒钱”，用来比喻大规模印钞，这个说法首次由美国经济学家Milton Friedman在1969年提出，2002年被美联储前主席伯南克作为可能对抗通缩的手段再度提起。
