Online Comparison Platform

You can explore model comparison techniques on the Online Comparison Platform (OCP). It offers many of the same features as MMB 3.1. and gives you access to pre-run simulations of all models for a subset of shocks and policy rules. For some examples of interesting comparisons please check out our Blog.


The latest MMB versions 2.3, 3.0 and 3.1 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.

For windows users we provide an "all-in-one installer", which you can download here. It installs the latest version of the MMB together with a suitable combination of Dynare and Octave.

We provide cross platform support for Windows, Mac and Linux. For any problem you encounter, please have a look at our FAQ section. 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.

For older versions of the MMB, Dynare and Octave you can go to the Archive.

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.

Download DYNARE

For Linux users, most common Linux distributions (Ubuntu, Debian, Arch,...) already provide pre-build packages through their package management systems.

Replication Package

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
