Abstract

On the basis of a laboratory experiment conducted at FAU, we investigated financial decisions under risk and ambiguity. We analyzed the degree of irrationality and the relationship between, on the one hand, financial literacy and mathematical abilities and, on the other hand, financial decisions. It turned out that one-third of subjects acted irrational at least once. Almost no subject was irrationally risk-seeking, whereas a large share of subjects was irrationally risk-averse. The numberof irrationally risk-averse subjects was higher in the case of ambiguity, when the probabilities of the uncertain events are unknown, than in the case of risk, when these probabilities are known. Subjects with higher financial literacy and better mathematical skills were less likely to actirrational. Mit einem an der FAU durchgeführten Laborexperiment haben wir finanzielle Entscheidungen bei Risiko beziehungsweise Ambiguität analysiert. Wir haben die Anfälligkeit für irrationale Entscheidungen sowie den Zusammenhang zwischen finanzieller Bildung und mathematischen Fähigkeiten einerseits und finanziellen Entscheidungen andererseits untersucht. In dem Experiment verhielt sich etwa ein Drittel der Teilnehmenden mindestens einmal irrational. Nahezu kein Teilnehmender des Experiments verhielt sich irrational risikofreudig, aber viele irrational risikoscheu. Bei Ambiguität, also wenn die Eintrittswahrscheinlichkeiten verschiedener möglicher finanzieller Ergebnisse unbekannt sind, trat irrational risikoscheues Verhalten in stärkerem Maße auf als bei Risiko, das heißt bei bekannten Eintrittswahrscheinlichkeiten. Höhere finanzielle Bildung und bessere mathematische Fertigkeiten gingen mit einer geringeren Wahrscheinlichkeit für irrationales Verhalten einher.
