The latest MMB versions 3.0 and 2.3 are released under the auspices of the Macroeconomic Model Comparison Initiative (MMCI), a joint project of the Hoover Institution at Stanford University and the Institute for Monetary and Financial Stability (IMFS) at Goethe University Frankfurt that is supported financially by the Alfred P. Sloan Foundation.
Note: Version 3.0 does not (yet) include all the functionality of the old v2.3 Matlab GUI, which can be found here. This for example includes direct editing of the mod files or detailed adjustment of the gain parameter for the adaptive learning models. These functionalities, among others, are scheduled for release version 3.1. Note that v2.3 does not feature the full list of models.
We provide cross platform support for Windows, Mac and Linux. We want to support and endorse the use of free and open source software for many reasons. The MMB is fully open source compatible and can be run without any propietary software. The source code can be browsed and downloaded directly on GitHub.
We would be very happy if you could give us a short user feedback by filling out our Questionnaire
The MMB is written in Octave/Matlab and utilizes the DYNARE environment (more detailed information can be found in the User Manual below). Mac-users can download the compatible Dynare version here. For more information on DYNARE, please, visit their project website.
For DYNARE versioning for GNU/Linux see here. Most common Linux distributions (Ubuntu, Debian, Arch,...) already provide pre-build packages through their package management systems.
Also, we provide a replication package, where a model code remains as close as possible to the authors' original code or article. To download it, simply click on the button below
A description of the policy rules incorporated in the MMB can be found at Policy Rules 3.0
Since we still keep the legacy 2.3 version around, find the respective documentation below. Note that these are not kept up to date.
