Zusammenfassung
Dieser Aufsatz stellt die Komplexitätsökonomik als Alternative zur neoklassischen Ökonomik vor und zeigt, wie sich die Sicht der Komplexitätsökonomik auf die Makroökonomie von derjenigen des neoklassischen Mainstreams unterscheidet. Nach einer theoretischen Einführung wird mikro- und makroökonomische Evidenz vorgestellt, die die Interpretation der Gesamtwirtschaft als komplexes adaptives System unterstützt. Komplexe adaptive Systeme weisen Pfad- und Kontextabhängigkeit auf, sind nur eingeschränkt prognostizierbar und nicht zentral zu steuern. Anschließend wird diskutiert, welche Implikationen die Komplexitätsökonomik für die Wirtschaftspolitik hat. Eine zentrale Aussage ist, dass es in komplexen adaptiven Systemen kaum möglich ist, optimale Politiken zu bestimmen und die Ökonomie durch zentrale wirtschaftspolitische Maßnahmen in einer gewünschten Weise zu lenken.
Danksagung
Ich danke Ralf Bergheim, Timo Henckel, Norman Isermann, Anna Klabunde, Julia Sprenger und Michael Thull für ihre sehr hilfreichen Kommentare. Auch die Anmerkungen dreier anonymer Gutachter haben sehr dazu beigetragen, den Aufsatz zu verbessern. Für alle verbliebenen Schwächen bin ich natürlich allein verantwortlich.
