This paper investigates empirically how and why men and women are different in their confidence levels. Using the data of the PISA test in math, confidence is decomposed into two dimensions: confidence in correct math knowledge and overconfidence in over-claiming false knowledge. The findings...

There is beauty in ethics, which in one of its declinations can be translated into this concept: there is beauty in undertaking the right action, even when nobody is watching. Within this, we can see an antidote to past failures, and an element necessary to attract the change that laws and...

This paper investigates the role of social capital in determining one's competitiveness. The analysis exploits the data of the PISA test in math because competitive occupational choices often require high quantitative skills. The empirical results highlight that a higher level of trust in school...

It is well established that boys perceive themselves to be better in mathematics than girls, even when their ability is the same. We examine the drivers of this male overconfidence in self-assessed mathematics ability using a longitudinal study of twins. This allows us to control for family...

The "grammar of trust" is one the most explored loci in game theory and behavioural economics. However, still much needs to be understood about the nature of trust in non-enforceable, personalised interactions, in markets and within organizations. This experimental study aims at contributing to...

We analyze gender differences in the trust game in a behind the veil of ignorance design. This method yields strategies that are consistent with actions observed in the classical trust game experiments. We observe that, on average, men and women do not differ in trust, and that women are...

The tendency to underestimate others' relative performance compared to one's own is widespread among individuals in all work environments. We examine the relationship between, and the driving forces behind, individual overconfidence and voluntary cooperation in team production. Our experimental...
