Trend Employment Growth and the Bunching of Job Creation and Destruction
利用美国制造业数据发现，就业破坏的波动通常大于就业创造，但在增长部门中情况相反。基于(S,s)型调整与趋势增长交互作用的模型解释了这一现象，但未能完全解释行业间相对波动与趋势增长的经验关系。
Research using U. S. manufacturing data finds that job destruction fluctuates more over time than job creation, but some new data indicate that this behavior is not shared in growing sectors, where job creation varies more. An explanation for this finding based on the interaction between (S,s)-type adjustment and trend employment growth delivers some tight predictions for the relationship between trend growth and the volatility of creation relative to destruction. Although it scores some notable successes, the simple (S,s)-based model augmented with a low-frequency trend cannot fully account for the strength of the empirical relationship between relative gross-flow volatility and trend growth across one-digit industries.
