But when you have only two tools left, neither of which is perfect for the job, the rational thing is to try both – credit policy and fiscal policy – at the same time. That is what the Obama administration is attempting to do right now.
但是当人们只剩下两个工具的时候，没有一个是可以胜任这一任务的。合情合理的措施就是把两个工具、也就是信贷政策和财政政策同时都试一下。这也就是奥巴马政府目前正在试图做的事情。
