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...

Dynamics of compliance, depending on audit probability, sanctions, and the time lag between audits, are investigated in a tax experiment. Compliance varied significantly over time: it decreased immediately after an audit and increased afterwards, especially if audits were frequent and sanctions...

The results of an asset market experiment, in which 64 subjects trade two assets on eight markets in a computerized continuous double auction, indicate that objectively irrelevant information influences trading behavior. Moreover, positively and negatively framed information leads to a...

In this paper we study information revelation on asset markets with endogenous and exogenous information. Our results indicate that superior information can only be exploited in the beginning of trading. Information disseminates on the market and informational advantages are counter-balanced...

In this paper, we apply the bounded rationality approach to an investment situation. In a simple setting where an investor decides between a riskless bond and a risky asset, we distinguish three aspiration levels: a lowest threshold which one wants to guarantee, the aspiration level given by...

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

A vast literature shows that individuals frequently violate normative principles in reasoning. In evaluating the relevance of these findings for psychology, economics, and related disciplines, it is natural to ask whether reasoning errors reflect random aberrations or systematic biases. One...

A vast literature shows that individuals frequently fail to identify the normative solutions in logical reasoning tasks. Much attention has been devoted to the study of these deviations at the individual level; less eVort was exerted to investigate whether institutional settings might facilitate...

In this paperwe relate individual risk attitude as elicited by binary lotteries and certainty equivalents to market behavior. By analyzing 26 independent markets with a total of 280 participants we show that binary lottery choices and certainty equivalents are pootly correlated. Only lottery...
