Abstract (eng)
The main objective of this master thesis has been the identification and investigation of potential relationships between clustered monetary beliefs, also termed ‘money scripts’, and some of the most important cognitive biases within the realms of finance and investment. Hence, an online-questionnaire was designed (N = 357) which mainly consisted of the Klontz Money Script Inventory-Revised (KMSI-R) as well as twenty different decision scenarios that were evenly distributed among the cognitive biases in question – namely overconfidence, illusion of control, sunk cost, loss aversion and the disposition effect. Later performed regression analyses unveiled numerous differences between the predictive values of various money scripts, especially regarding overconfidence and illusion of control. Differences, however, were not exclusively attributable to the implications of the phenomena at hand; at times they could also be traced back to diverging preferences with regards to framing and formulation aspects of scenarios and their subsequent possible answers, respectively. A deeper understanding of the ramifications of monetary beliefs on financial decision-making under uncertainty is vital for optimizing individual financial capacity; this thesis aims to provide a psychological and empirical contribution to this ongoing endeavor.
