Replication file in Dynare

General DSGE Modeling Replication Attempts
1

Dear Prof. @jpfeifer

  1. Is it possible to access your paper’s Dynare code for “Mr. Keynes meets the Classics: Government Spending and the Real Exchange Rate” (published in the Journal of Political Economy, 2024). The journal has the files in Matlab formats and I am wondering if there is .mod file replication.

  2. Out of curiosity, is there any reference or lecture notes that shows/proof why in linear DSGE models, unit root variables does not affect the slope of the policy function ?

Many thanks in advance
Best,
