Furthermore, these studies deal with only the theoretical arguments and to...

Die Einführung neuartiger Energietechnologien wird allgemein als der Schlüssel zur Senkung klimaschädlicher Treibhausgase angesehen. Allerdings ist die Abbildung derartiger Technologien in numerischen Modellen zur Simulation und ökonomischen Analyse von energie- und klimaschutzpolitischen...

Die vorliegende Dissertation beschäftigt sich hauptsächlich mit zwei Fragen: Erstens, welche Faktoren beein-flussen den Prozess, durch den sich neue Technologien unter Firmen verbreiten? Zweitens, welche Konsequen-zen ergeben sich aus der Verbreitung neuer Technologien? Beide Fragen...
