One thing is clear: economists no longer dare to assume that trend is trend and cycle is cycle, and that their reciprocal interactions are small enough to neglect on the first pass. That approach has left many economists themselves living in countries that are considerably poorer than they expected.
有一点是肯定的：经济学家不再敢认为趋势就是趋势，周期就是周期，它们发生交错的情况很少，可以忽略不计。这一方针让很多经济学家生活在比远比他们的预期更穷的国家。
