New version of "Macroeconomic Model Data Base“ now offers more than 120 models

The open platform for macroeconomic models of the IMFS continues to expand. In a joint research project with the Hoover Institution, the new version MMB3.0 of the website now offers 128 models and further technical features.

The Macroeconomic Model Data Base (MMB) is an open database for macroeconomic models developed by Prof. Volker Wieland and his team, where researchers can share formulas and codes of their models and also reproduce the calculations of other researchers. In the framework of a joint research project with Hoover Institution supported by the Sloan Foundation, the Macroeconomic Modeling and Comparison Initiative (MMCI), the database is being developed and enlarged.

The MMB users are able to directly contribute new models and scenarios on the interactive platform and now can use a keyword search for the models in the database. In the forum, researchers can discuss model replication and comparison or ask specific questions and receive advice by the community.

On the platform, users can analyze in various models at the same time the consequences of a cut or a rise in interest rates, a tax reform or a stimulus package. Models of the Federal Reserve, the European Central Bank, the European Commission, the International Monetary Fund as well as the central banks of Sweden, Canada and Chile are integrated on the platform. The database now has been extended by some structural models featuring unconventional monetary policy.
