There is room in economics for grand speculation – some part intuition, some part common sense, and some part ideology. If economists were to wait for careful studies before offering opinions about policy, we would never have anything timely to say.
经济学具有大胆猜测的空间——一部分来自直觉，一部分来自常识，一部分来自意识形态。如果经济学家等到仔细的研究出现之后再给出政策选择建议，我们就不可能及时发出任何声音。显然，让一些经济直觉来指导政策比一刀切杜绝经济直觉好。
