We test experimentally an explanation of over and under confidence as motivated by (perhaps unconscious) strategic concerns, and find compelling evidence supporting this hypothesis in the behavior of participants who send and respond to others ́statements of confidence about how well they have...

A nascent but burgeoning literature examines the importance of non-cognitive skills in determining success across many facets of life. The majority of these papers treat these skills as fixed traits for adults. We estimate the impact of a number of life events on the Big Five personality traits...

Child skills are shaped by parental investments. Health shocks to parents can affect these investments and their children's skills. This paper estimates causal effects of severe parental health shocks on child socio-emotional skills. Drawing on a large-scale survey linked to hospital records, we...

We examine the association between the personality trait grit and post-compulsory educational choices and trajectories using a large survey linked to administrative student register data. Exploiting cross sectional variation in students' self-reported grit in the last year of compulsory school,...

We study the relationship between parenting style and a broad range of children’s skills and outcomes. Based on survey and experimental data from 5,580 children and their parents, we find that children exposed to positive parenting have higher IQs, are more altruistic, open to new...

Understanding the roots of human cooperation among strangers is of great importance for solving pressing social dilemmas and maintening public goods in human societies. We study the development of cooperation in 929 young children, aged 3 to 6. In a unified experimental framework, we examine...

Overbidding in second-price auctions (SPAs) has been shown to be persistent and associated with cognitive ability. We study experimentally to what extent cross-game learning can reduce overbidding in SPAs, taking into account cognitive skills. Employing an order-balanced design, we use...

We study the development of cooperation in 929 young children, aged 3 to 6. In a unified experimental framework, we examine pre-registered hypotheses about which of three fundamental pillars of human cooperation – direct and indirect reciprocity, and third-party punishment – emerges earliest...
