A structural model of aggregate US job flows: another look
重新估计了Collard等人提出的美国总体就业流动结构模型，通过加入就业率矩条件解决了原模型参数估计导致失业率高达99%的问题，并呼吁重新评估该模型。
Abstract A recent article (Collard et al. , 2002 ) published in this journal presented a structural model of aggregate job flows. Unrestricted estimation of the model yields parameter estimates that would imply an unemployment rate of 99%. Instead of solving this problem by fixing one of the parameters, as originally attempted by the authors, I add moments regarding the employment rate. The new results call for a re‐evaluation of the model. Copyright © 2003 John Wiley & Sons, Ltd.
