Dear Dynare’s users,

I tried to replicate (an estimated Monetary DSGE Model with unemployment and staggered nomianl wage bargaining ) Gertler, SALA and Trigari 2008. The model is already log-linearized in the article. Dynare gives me impulses responses but their don’t coincide with the one in the article. For some parameters, i guess the value because i can’t find it in the paper. ( i wrote guess near paramaters without values in codes) Can someone give me any suggestion to resolve the problem please?

Thank you for the help.

Clara

Have you tried asking the authors about these parameters?
