The Relationships between Permanent and Transitory Movements in U.S. Output and the Unemployment Rate
估计了美国产出和失业率中的永久性与暂时性变动，发现永久性变动对整体波动解释力强，且两者永久成分的相关性主导了序列变化的关联。
This paper estimates the permanent and transitory movements in U.S. output and the unemployment rate and the relationships between them. The results suggest that permanent movements in U.S. output and the unemployment rate are important for explaining overall fluctuations. Further, the correlation between changes in these series arises in large part due to the relationship between their permanent components.
