The Macroeconomic Model Data Base

The Macroeconomic Model Data Base (MMB) is an archive of macroeconomic models based on a common computational platform that provides various tools for systematic model comparison. The project is headed by Volker Wieland, Professor of Monetary Economics at the Institute for Monetary and Financial Stability (IMFS) at Goethe University Frankfurt.

The latest MMB version 2.2 is 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.

MMCI aims to change how research on structural macroeconomic modeling for monetary, fiscal and macro-prudential policy analysis is conducted – by making it much more reproducible, collaborative and comparative in nature. Its principal investigators are Michael Binder (IMFS, Goethe University Frankfurt), John Taylor (Stanford University and Hoover Institution) and Volker Wieland. A key objective is to extend the coverage of macroeconomic models in MMB, to enhance its functionality and develop new tools for researchers at large. 

Furthermore, MMCI has launched a new network of researchers with the help of the Center of Economic Policy Research (CEPR). This Macroeconomic Modeling and Model Comparison Network (MMCN) aims to promote collaboration among interested researchers in academia and policy institutions. It provides a forum for presenting new models and model comparisons, as well as the solution and estimation methods underlying them, thereby enhancing opportunities for building on the work of others.

We would like to thank the researchers who shared their model codes and/or assisted in model replication as well as Ph.D. students at Goethe University who helped implementing models in the database, listed here.
