This paper suggests a potential rationale for the recent empirical finding that overconfident agents tend to self-select into more competitive environments (e.g. Dohmen and Falk, 2006). In particular, it shows that moderate overconfidence in a contest can improve the agent's performance relative...

This paper reports data from an ultimatum mini-game in which responders first had to choose whether or not to participate. Participation was costly, but the participation cost was smaller than the minimum payoff that a responder could guarantee himself in the ultimatum game. Compared to a...

This paper considers the effects of a two-period interaction on the decision of a principal to delegate authority to a potentially biased but better informed agent. Compared to the (repeated) one-period case, the agent's first period actions may also signal his type which in turn impacts wages...

Over the last decades, research in behavioural economics has demonstrated that individual welfare (utility), as relevant for economic decision making, depends not only on absolut but also on distributional aspects. Moreover, evidence is gathering that something similar holds for aggregate...

Allowing for a free choice of the recipient's gender in a dictator game (N = 508), we find that women show a substantial gender biased towards females. Adding a charity recipient to the possible choices, the charity becomes the primary recipient and overall transfers increase. Yet, conditioning...

Integrating individual inequity aversion into a utilitarian social welfare function, we derive a simple welfare measure which comprises both GDP and income inequality as measured by the Gini-index. The provided theoretical link between inequity aversion (popular in behavioural microeconomics)...

This paper compares two prominent empirical measures of individual risk attitudes - the Holt and Laury (2002) lottery-choice task and the multi-item questionnaire advocated by Dohmen, Falk, Huffman, Schupp, Sunde and Wagner (forthcoming) - with respect to (a) their within-subject stability over...

In this paper, we study the individual payoff effects of overconfident self-perception in teams. In particular, we demonstrate that the welfare of an overconfident agent in a team of one rational and one overconfident agent or a team of two overconfident agents can be higher than that of the...

This paper considers the effects of an interim performance evaluation on the decision of a principal to delegate authority to a potentially biased but better informed agent. Assuming the agents' outside option to be determined by market beliefs about their type, interim evaluations (a) provide a...

How can an argument that is based on assumptions known to be false deliver any insightful conclusions let alone be used for policy recommendations? Over the years, a variety of concerns regarding (micro-)economic modelling and its relevance for real life have been expressed along these lines....
