Individuals frequently face intertemporal decisions. For the purposes of economic analysis, the preference parameters assumed to govern these decisions are generally considered to be stable economic primitives. However, evidence on the stability of time preferences is notably lacking. In a large...

Standard economic analysis assumes that people make choices that maximize their utility. Yet both popular discourse and other fields assume that people sometimes fail to make optimal choices and thus adversely affect their own happiness. Most social sciences thus frequently describe some...

We report an experiment that infers true overconfidence in relative ability through actions, as opposed to reported beliefs. Subjects choose how to invest earnings from a skill task when the returns depend solely upon risk, or both risk and relative placement, enabling joint estimation of...

We study in an online, real-effort experiment how the bracketing of non-binding goals affects performance in a work-leisure self-control problem. We externally induce the goal bracket – daily goals or a weekly goal – and within that bracket let subjects set goals for how much they want to...

We document that an internal locus of control can be hindering in financial market situations, where short-term outcomes are determined by chance. The reason is that internally controlled individuals may tend to (over-)react to random outcomes. Our evidence is based on an experiment in which...

Can we nudge children, adolescents and their parents to make better decisions on education? And can we nudge teachers to support and encourage better decision making? Education decisions are taken at young ages and involve immediate costs and potential, future benefits. In such settings...

We present experimental evidence which sheds new light on why women may be less competitive than men. Specifically, we observe striking differences in how men and women respond to good and bad luck in a competitive environment. Following a loss, women tend to reduce effort, and the effect is...

We study gender differences in the willingness to compete in a large-scale experiment with 1,035 children and teenagers, aged three to eighteen years. Using an easy math task for children older than eight years and a running task for the younger ones we find that boys are much more likely to...

Recent research has shown that women shy away from competition more often than men. We evaluate experimentally three alternative policy interventions to promote women in competitions: Quotas, Preferential Treatment, and Repetition of the Competition unless a critical number of female winners is...
