Dynare forums

I tried to replicate "A Small New Keynesian Model of the New Zealand Economy" http://www.rbnz.govt.nz/-/media/Reserve ... p06-03.pdf building on Gali and Monacelli 2005. The 14 log-linearised equations are clearly given in the appendix. However when putting them in a mod-file the below error occurred when using Dynare 4.4.3 as well as yesterday's unstable version.

Thanks a lot for your help

My guess is that the problem comes from the last equation

Code: Select all

rstar-rstar(+1)=RHORSTAR*(rstar(-1)-pistar)+vrstar;


It is different from the Appendix. Moreover, there is no way to disentangle which part of the exogenous foreign real interest rate comes from rstar and which from pistar. They are only jointly determined. Therefore. you might need to define rstar(-1)-pistar as one variable.

Thank you very much! It was exactly the way you suspected. After correcting the typo and redefining rstar(-1)-pistar, I retrieved some results.
