Abstract

Das schwache Rationalitaetsprinzip ist eine heuristische Regel, wie man in den Sozialwissenschaften sinnvollerweise vorgehen kann. Es ist notwendiger Bestandteil jeder ‚verstehenden‘ Sozialwissenschaft im Sinne von Max Weber. Zunaechst werden dieses Prinzip und seine Rolle im Rahmen der oekonomischen Theoriebildung diskutiert. Dabei wird auch auf die Sinnhaftigkeit einer Mikrofundierung fuer die makrooekonomische Theorie eingegangen. Danach wird aufgezeigt, welche Rolle dieses Prinzip auch in Konzepten eingeschraenkter Rationalitaet spielt. Der Beitrag schliesst mit einigen Bemerkungen zur Behandlung der Probleme des freien Willens sowie der Willensschwaeche im Rahmen des oekonomischen Verhaltensmodells. (The weak rationality principle is not an empirical statement but a heuristic rule for how to proceed in social sciences. It is a necessary ingredient of any ‘understanding’ social science in the Weberian sense. In this paper, first this principle and its role in economic theorizing are discussed. It is also explained why it makes sense to use a micro-foundation and, therefore, to employ the rationality assumption in economic models. Then, we discuss whether the anomalies of individual behaviour as highlighted in modern behavioural economics impair the applicability of the weak rationality principle. This is not the case. We conclude with some remarks on handling the problems of ‘free will’ as well as ‘weakness of the will’ within the economic approach.)
