E-Stabilty: Über die Lernbarkeit von rationalen Erwatungsgleichgewichten


  • Henzel, Steffen
  • Mayer, Eric
  • Schimpfermann, Bodo


Dieses vorläufige Papier beinhaltet keinerlei neuen Erkenntnisse, sondern fasst lediglich einige zentrale Aspekte der makroökonomischen Lerntheorie (siehe Evans, Honkajohja (2001)) knapp zusammen. Es wird der Frage nachgegangen ob rationale Erwartungsgleichgewichte lernbar sind. Lernen bedeutet in diesem Zusammenhang im Wesentlichen, dass die ökonomischen Agenten mit dem Eintreffen neuer Daten ihre Schätzungen über makroökonomische Strukturgleichungen revidieren. Ökonomische Agenten können also so beschrieben werden, als ob sie wie ein Ökonometriker neue Informationen verarbeiten. In diesem kleinen Beitrag wollen wir erörtern welche formalen Bedingungen für stabiles adaptives Lernen erfüllt sein müssen.
