Das IMM: ein makroökonometrisches Mehrländermodell

  • Christian Dreger
  • Florian Zinsmeister

We present a macroeconometric model for the large EU economies, i.e. Germany, the UK, France and Italy (Big4 model). The general model structure is based on the system of national accounts. Behavioural relationships are specified in error correction form for the supply and demand side at product and factor markets, income distribution, and the evolution of prices, interest and exchange rates. In addition, the public sector is discussed in detail especially for the German economy. The model provides a consistent framework for the regular short and medium term forecasts at DIW Berlin. Moreover, the model is used to simulate the effects of alternative economic policy options. In diesem Beitrag wird ein internationales makroökonometrisches Modell präsentiert, das Deutschland, Großbritannien, Frankreich und Italien als separate Ländermodule enthält (Big4-Modell). Die Modellstruktur basiert auf dem volkswirtschaftlichen Kreislaufschema. Die Verhaltensbeziehungen sind in Fehlerkorrekturform für das Angebot und die Nachfrage auf den Güter- und Faktormärkten, die Einkommensverteilung sowie für die Preis-, Zins- und Wechselkursentwicklung spezifiziert. Zudem wird der öffentliche Sektor berücksichtigt, der insbesondere für Deutschland detailliert dargestellt ist. Das Modell liegt den kurz- und mittelfristigen Prognosen der gesamtwirtschaftlichen Entwicklung zugrunde, die das DIW Berlin kontinuierlich durchführt. Darüber hinaus wird das Modell zur Simulation der Effekte alternativer wirtschaftspolitischer Maßnahmen eingesetzt.
