In elementary school, girls typically outperform boys in languages and boys typically outperform girls in math. The determinants of these differences have remained largely unexplored. Using rich data from Dutch elementary schools, we decompose the differences in achievement into gender...

Intelligence quotient (IQ), grades, and scores on achievement tests are widely used as measures of cognition, yet the correlations among them are far from perfect. This paper uses a variety of data sets to show that personality and IQ predict grades and scores on achievement tests. Personality...

This paper studies the causal effect of birth spacing (i.e., the age difference between siblings) on personality traits. We use longitudinal data from a large British cohort which has been followed from birth until age 42. Following earlier studies, we employ miscarriages between the first and...

This paper studies self-control in a nationally representative sample. Using the well-established Tangney scale to measure trait self-control, we find that people’s age as well as the political and economic institutions they are exposed to have an economically meaningful impact on their level...

This paper examines whether men's and women's noncognitive skills influence their occupational attainment and, if so, whether this contributes to the disparity in their relative wages. We find that noncognitive skills have a substantial effect on the probability of employment in many, though not...

This paper studies whether sibling gender affects personality traits. We use the idea that if parents decide to have a second child, it is random whether they will have a boy or a girl. Therefore, the relationship between the second-born sibling's gender and the first sibling's personality...

This study investigates the predictive power of self-control for individuals and their children using population representative data. We use the well-established Brief Self-Control Scale to demonstrate that people's trait self-control is highly predictive of their life outcomes. Higher...

This research estimates models of the importance of conscientiousness for socio-economic outcomes. We use measures of conscientiousness at age 16 to explain adult wages and other outcomes, such as crime, health and savings behaviour. We use several waves from the 1970 British Cohort Study. Our...
