摘要：This paper aims to study whether a simple asymmetric adjustment costs model with tractable heterogeneity can account for the observed distribution of French aggregate job flows. Each firm chooses endogenously its level of hiring or firing depending on the level of a specific technology shock. These policy rules allows, via aggregation, to account for dynamics in aggregate job flows. The deep parameters of the model are then estimated using the Simulated Method of Moments. We then show that the model is able to match some key features of the French aggregate job flows, but the results appears sensitive to the level of heterogeneity.
