Dynare

My personal Dynare git repository can be found here. If Git is installed on your computer, you can clone the repository using the following command in a shell:

git clone http://git.ithaca.fr/dynare.git

This repository contains (experimental and highly unstable) additional branches (compared to Dynare official git repository). Binaries are not provided, so you have to compile the mex files and preprocessor (following the documentation given on the DynareWiki here). There is no documentation about the new features implemented in these branches.

This is just a small example of perfect foresight model with an analytical steadys state. The mod and steadystate file are self documented.

• dog.mod
  
• dog_steadystate.m
  

The mod and steadystate files are provided without any documentation, but are (should be) human (macroeconomist or dynare user) readable. The steadystate file is called by dynare to compute the deterministic steady state of the non-linear model. Note that with the most recent version of dynare (snapshot or 4.2) it is possible to declare the analytical steady state directly in the mod file. The main limits of this new feature are that (i) exceptions cannot be defined (for some values of the deep parameters a sensible steady state may not exist) and (ii) parameters cannot be updated with steady state restrictions. The provided steadystate file uses persistent variables for speed improvements and defines a set of exceptions (for instance if the depreciation rate is found to be negative negative for some values of the deep parameters and/or calibrated/estimated steady state ratios).

• sw.mod
  
• sw_steadystate.m
