Sticky Information DSGE Model (Reis 2009)

Dear Dynarers,

Hello, I try to solve a sticky information DSGE model (Reis 2009).

Is it possible to write the model in nonlinear forms in Dynare?
Or should I log-linearize the model?

Thank you for your help!

Do you mean the AEJ: Macro paper? Section 1D suggests that you need the linearity to do the aggregation in the sticky information case. The nonlinear model would not work.
