[eng] This article compares the performance of VAR and DSGE models. We use the maximum likelihood method to estimate the models for the growth rates of U.S. hourly labor productivity and hours worked in 1959-2003. We show that DSGE models, when they include sufficient real rigidities (such as...

This paper contributes to the analysis of jobs flows dynamics through the explicit modelling of job creations and job destructions. We propose a simple matching model extended for endogenous separation and tractable heterogeneity. The parameters of the model are estimated using a...
