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...

In this paper we relate individual risk attitude as elicited by binary lotteriesand certainty equivalents to market behavior. By analyzing 26 independentmarkets with a total of 280 participants we show that binary lottery choicesand certainty equivalents are poorly correlated. Only lottery...

This experimental study investigates whether individuals preferbounded rationality over rational choice theory when facing simpleinvestment tasks. First, participants state some personal parametersthat serve as an input to render a theoretical approach, namelysatisficing or optimality,...

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...

Threat power is the ability to impose a great loss on someone else at relativelylow own cost and can be measured by the ratio of other’s and own loss. It can bevaried by assuming that rejecting an ultimatum reduces the payoff of the proposerto its lambda–share and that of the responder to...

We experimentally investigate whether individuals can reliably detect cooperators in an anonymous decision environment by allowing participants to condition their choices in an asymmetric prisoner's dilemma and a trust game (i) on their partner's donation share to a self-selected charity, and...

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...

In this paper we study the robustness of the deadline effect in bargaininggames using constant and slowly decreasing pies, different time horizons,and both constant and alternating role modes. With decreasing pies efficiency requires early agreements while constant pies allow for efficient late...

Overall, 72 subjects invest their endowment in four risky assets. Each com-bination of assets yields the same expected return and variance of returns. Illusion of expertise prevails when one prefers nevertheless the self-selected portfolio. After being randomly assigned to groups of four...

In this paper, we apply the bounded rationality approach to aninvestment situation. In a simple setting where an investor decides betweena riskless bond and a risky asset, we distinguish three aspirationlevels: a lowest threshold that one wants to guarantee, an aspirationlevel given by investing...
