Tool: DYNARE  

  • Dynare is a software platform for handling a wide class of economic models, in particular dynamic stochastic general equilibrium (DSGE). Dynare is a free software, which means that it can be downloaded free of charge. Download dynare from the download page. Dynare needs MATLAB, which is not free. Campus licenses for MATLAB allow to download the software for free in PC connected to the Sapienza University net (details). 
  • A good alternative to MATLAB is to use Octave, which is a freeware software!!!! Download the Octave installer at the Octave download page. Double-click on the Octave installer and follow the instructions. Download the latest Dynare Windows installer at the download page. Double-click on the Dynare installer and follow the instructions. Run Octave by locating it in the Windows start menu or on the desktop and by clicking on its icon. Configuring Octave for Dynare. At the Octave command prompt, type the following, replacing 4.x.y with your Dynare version.
  • You can download the dynare user guide here (T. Mancini Griffoli)
