The overconfidence bias is discussed extensively in economic studies, yet fails to hold experimentally once monetary incentives and feedback are implemented. We consider overconfidence as a social bias. For a simple real effort task, we show that, individually, economic conditions effectively...

This paper experimentally investigates the nature of impulses in impulse learning. Particularly, we analyze whether positive feedback (i.e., yielding a superior payoff in a game) or negative feedback (i.e., yielding an inferior payoff in a game) leads to a systematic change in the individual...

Abstract This study presents results of the validation of an ultra-short survey measure of patience included in the German Socio-Economic Panel (SOEP). Survey responses predict intertemporal choice behavior in incentive-compatible decisions in a representative sample of the German adult population.

We test experimentally a prediction of the ‘moral credit model’, in which committing a virtuous act creates moral credits that can license immoral behavior in a succeeding decision. We use a basic cheating experiment that was either preceded by a virtuous deed or not in a developing country...

How do people react to a mix of good deeds to a third party and bad deeds against them? A modified ultimatum game shows that previous good deeds make responders substantially more tolerant to unfair proposals.

Is it possible to elicit reliable assessment from an assessor having a conflict of interest (e.g. a professor that writes a recommendation letter for a formal PhD student)? We propose an experimental test and show that compared to a not-incentivized assessment, a promise to give a truthful...

In three binary choice problems, people reveal a choice pattern which falsifies expected utility theory and many generalized non-expected utility theories. This new paradox challenges popular non-expected utility models analogously to how the Allais paradox challenged neoclassical expected...

A stag-hunt game (with the risky and safe actions) has two pure Nash equilibria that are Pareto-rankable. The risky action leads either to the Pareto-superior equilibrium (high payoff) or to out of equilibrium (low payoff) depending on the opponent’s action. Both players may want to obtain...

This study presents results of the validation of an ultra-short survey measure of patience included in the German Socio-Economic Panel (SOEP). Survey responses predict intertemporal choice behavior in incentive-compatible decisions in a representative sample of the German adult population.

We present a multi-trial experiment that extends the classic experiment of Thaler et al. (1997) by adding short-term information to long-term investment. The allocation to the risky asset is reduced in the long-term, when we add short-term information.
