Their calibration incorporates micro- and macro-level evidence on worker and job flows. The authors show that the dynamic stochastic equilibrium of the model replicates important cyclical features of worker flows and job flow simultaneously. In particular, the model correctly predicts that hires from unemployment move countercyclically while the job creation rate moves procyclically. The key to this result is to allow for a large hiring flow that does not go through unemployment but is part of job creation, for which procyclicality of the job finding rate dominates its cyclicality. The authors also show that the model generates large volatilities of unemployment and vacancies when a worker's outside option is at 83 percent of aggregate labor productivity.
