Forschung am Lehrstuhl für Makroökonomik

Die Forschung am Lehrstuhl für Makroökonomik befasst sich insbesondere mit der Analyise makroökonomischer Zusammenhänge mittels dynamischer stochastischer Modelle. Besondere Forschungsschwerpunkte sind:

  • Macrofinance, insbesondere die makroökonomische Rolle von Kreditsicherheiten und Kreditbeschränkungen
  • Computational Economics, insbesondere numerische Methoden zur Berechnung globaler Lösungen von hoch-dimensionalen dynamisch-stochastischen Gleichgewichtsmodellen
  • Allgemeine Gleichgewichtstheorie, insbesondere die Existenz von rekursiven Gleichgewichten in dynamisch-stochastischen Modellen mit heterogenen Agenten

Relevante Publikationen, Arbeitspapiere und laufende Forschungsprojekte sind unten aufgelistet.
