Economists often estimate economic models on data and use the point estimates as a stand-in for the truth when studying the model's implications for optimal decision-making. This practice ignores model ambiguity, exposes the decision problem to misspecification, and ultimately leads to...

Wage growth occurs almost exclusively in full-time work, whereas it is close to zero in part-time work. German women, when asked to predict their own potential wage outcomes, show severely biased expectations with strong over-optimism about the returns to part-time experience. We estimate a...

This paper explores inequalities in IQ and economic preferences between children from high and low socio-economic status (SES) families. We document that children from high SES families are more intelligent, patient and altruistic, as well as less risk-seeking. To understand the underlying...

This study presents descriptive and causal evidence on the role of social environment for the formation of prosociality. In a first step, we show that socioeconomic status (SES) as well as the intensity of mother-child interaction and mothers' prosocial attitudes are systematically related to...

Why does patience vary across individuals and countries? We provide evidence on a widely-hypothesized mechanism, namely that higher longevity fosters patience. Using data on patience for 80,000 individuals in 76 countries, this paper relates exogenous variation in longevity across...

This study presents descriptive and causal evidence on the role of the social environment in shaping the accuracy of self-assessment. We introduce a novel incentivized measurement tool to measure the accuracy of self-assessment among children and use this tool to show that children from high...

Inequality of opportunity strikes when two children with the same academic performance are sent to diff erent quality schools because their parents di ffer in socio-economic status. Based on a novel dataset for Germany, we demonstrate that children are signi ficantly less likely to enter the...

This paper studies the relationship between patience and comparative development through a combination of reduced-form analyses and model estimations. Based on a globally representative dataset on time preference in 76 countries, we document two sets of stylized facts. First, patience is...

We present evidence on the role of the social environment for the development of gender differences in competitiveness and earnings expectations. First, we document that the gender gap in competitiveness and earnings expectations is more pronounced among adolescents with low socioeconomic status...

Reporting private information is a key part of economic decision making. A recent literature has found that many people have a preference for honest reporting, contrary to usual economic assumptions. In this paper, we investigate whether preferences for honesty are malleable and what determines...
