We experimentally test overconfidence in investment decisions by offering participants the possibility to substitute their own for alternative investment choices.Overall, 149 subjects participated in two experiments, one with just one risky asset, the other with two risky assets. Overconfidence...

The concept of a non-extreme-outcome-additive capacity (neo-additive capacity ) is introduced.Neo-additive capacitiesmodel optimistic and pessimistic attitudes towards uncertaintyas observed in many experimental studies. Moreover, neo-additive capacities canbe applied easily in economic...

We experimentally investigate whether the satisficing approach isabsorbable, i.e., whether it still applies after participants become awareof it. In a setting where an investor decides between a riskless bondand either one or two risky assets, we familiarize participants with thesatisficing...

The paper explores the applicability of the satisficing approach. Inparticular, we investigate whether basic principles of aspiration formationand satisficing behavior are transferable between similar situations.Individuals are sequentially confronted with two risky investmenttasks, a simple and...

The satisficing approach with its three constituent processes, aspiration formation,satisficing, and aspiration adjustment, is formally elaborated for a specificclass of portfolio selection tasks. It is partly poorly confirmed by experimentaldata, indicating that bounded rationality requires...

Das Anspruchserfüllungskonzept mit seinen Bausteinen "Anspruchsbildung, Anspruchserfüllung und Anspruchsanpassung" ist die zentrale Idee in der Theorie des eingeschränkten rationalen Entscheidens. Ähnlich wie die Rationalwahltheorie, die ohne kühne Einschränkungen, zum Beispiel der...

This paper investigates factors influencing individual portfolio allocations withparticular focus on the role of illusion of control. By forming their portfolio of tworisky lotteries and one risk-less alternative, subjects are requested to reach a targetinvestment profit, whereby equal...

An empirically well-established finding is that equity portfolios are concentratedin the domestic equity market of the investor. Previous theoreticaland empirical analyses have mainly focused on institutional explanations andlargely neglected individual behavior. In this study we report the...

This paper focuses on egocentric biases in financial decisions. Subjects first designa portfolio, whereby each combination of assets yields the same expected returnand variance of returns. They are then confronted with two alternative portfolios;the average portfolio and the portfolio of one’s...
