In that case, our social profit is not $210 billion but rather $390 billion, and we should certainly do this again. Indeed, we should do it repeatedly, until there are signs that additional stimulus may start to threaten price or debt-management stability, or until unemployment falls far enough to make Barro’s multipliers overestimates.
在这种情况下，我们的社会利润就不是 2100 亿美元，而是 3900 亿美元。我们当然应该这么做。实际上，我们还应该反复地这么做，直到有迹象表明额外的刺激开始威胁到价格或是债务处理的稳定性。或是直到失业率显著下降。
