解释：
题目说eco recovery不是意思是说经济复苏吗，经济从谷底往上走，但是失业率没有马上下来，问为什么。不是这样理解吗？
解释里面是说经济下行，不懂了
NO.PZ2017100901000020 问题如下 ring economic recovery, a lagging unemployment rate is most likely attributable to: A.businesses quickly rehiring workers. B.new job seekers entering the labor force. C.unremployeworkers transitioning to higher-paying jobs. B is correct.In economic recovery, new job seekers return to the labor force, anbecause they selm finwork immeately, their return minitially raise the unemployment rate.考点Unemployment解析因为在经济刚开始不景气的时候，企业主会通过减少工人工作小时数的方法调节生产，只有当经济进一步衰退时才会考虑裁员，所以B说法正确。经济不景气的时候企业主无意培训新员工，工人也很难找到培训再就业的机会，所以A,C都错误。 RT

NO.PZ2017100901000020 ac不选明白，B的意思是招新工作的人加入到labor force里 我的问题是为什么会有new job seeker entering，recovery的时候经济变好，但老板还在裁员是吗？所以才有new job seeker entering labor force？是因为unemployment 是lag指标，所以实际recovery时候，老板还在裁员？所以更多的没工作的人进入labor？不太理解这块
NO.PZ2017100901000020 new job seeker的进入会使得unemployment rate 的分母增加，但为啥会导致滞后指标呢？不是很理解，希望能一下，谢谢
