This research investigates to what extent subjective teacher assessment of children's ability adds to the use of test scores in the explanation of children's outcomes in the transition from elementary to secondary school in terms of initial track allocation, track switching in the first three...

A growing number of economic studies show that low emotional stability is typically negatively related to socioeconomic outcomes, while conscientiousness predicts desirable results. However, possible mechanisms behind these relations are far less explored. Gaining insights into the mechanisms is...

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...

Several studies document the fact that low-educated workers participate less often in further training than high-educated workers. The economic literature suggests that there is no significant difference in employer willingness to train low-educated workers, which leaves the question of why the...

This research documents employment opportunities of labour-market entrants during the COVID-19 crisis in the Netherlands. Two recent cohorts of graduates are studied and compared to two pre-COVID-19 cohorts: the 2019 cohort was unexpectedly hit by the COVID-19 crisis about six months after...

This research documents the effects of different forms of family disruptions – measured by separation, divorce and death – on personality development of British children included in the 1970 British Cohort Study. There are statistically significant correlations between family disruptions...

This paper reviews the recent literature on measuring and boosting cognitive and non-cognitive skills. The literature establishes that achievement tests do not adequately capture character skills: personality traits, goals, motivations, and preferences that are valued in the labor market, in...

This paper analyses changes in job opportunities of older workers in the Netherlands in the period 1996-2010. The standard human capital model predicts that, as a result of human capital obsolescence, mobility becomes more costly when workers become older. We measure and interpret how changing...

This research provides an economic model of the way people behave during an IQ test. We distinguish a technology that describes how time investment improves performance from preferences that determine how much time people invest in each question. We disentangle these two elements empirically...

This research applies a task-based approach to measure and interpret changes in the employment structure of the 168 largest US cities in the period 1990-2009. As a result of technological change some tasks can be placed at distance, while others require proximity. We construct a measure of task...
