Seminar paper from the year 2008 in the subject Business economics - Economic and Social History, grade: 1,0, University of Aarhus, Denmark (University of Aarhus - Denmark, School of Economics and Management), language: English, abstract: In times of open or suppressed inflation when a monetary reform becomes inevitable, economic theory can help to make the right decisions. Monetary concepts like the quantity equation and the theory of monetary reforms would have helped to avoid the mistakes of the Danish reform in 1813. Additionally, they would have confirmed the decision makers of the German reform in 1948 in their actions. Fortgeschrittene offene oder gro e zurückgestaute Inflation zieht meist zwangslنufig eine sanierende Wنhrungsreform nach sich. Hierbei kann die Geldtheorie helfen, die richtigen Entscheidungen zu treffen. Konzepte wie die Quantitنtsgleichung hنtten geholfen, die Fehler der dنnischen Wنhrungsreform von 1813 zu vermeiden. Die Theorie hنtte die Entscheidungstrنger der deutschen Wنhrungsreform von 1948 in ihrem Vorhaben bestنrkt.
