Bayesian steady state measurement error

Hi everyone,

I am running model of Uribe. In simulation, I obtain the same results with Uribe. But estimation does not work even if I use the same priors with the paper and mode-compute-6. The problem may be related to measurement errors equation. But i dont know how to deal with this. Estimation works when i am estimating 16 parameters. But if i include parameter gd and estimate 17 paramaters, it fails. It gives me this results:

Another question is: i am making first order approximation and working with nonlinear model. ı did not loglinearize the model. Why do variables dynare names as smoothed variables take negative values?


I will really appreaciate your help. Thanks!

You have a problem with steady state computation/updating: see also http://www.dynare.org/phpBB3/viewtopic.php?f=1&t=4148

Thank you for your suggestion. I attached my codes. Before model blocks I defined 10 parameters which depend on parameter gd. If I understand correctly in estimation i need to change these parameters but they dont. To update parameters depending on gd i need to write them in model block or write a steady state file. Am ı right? Could you send me your steady state file? Which one is better in my case writing in model block or using steady state file?
