The NATural GAS model is an integrated model of the European wholesale gas market providing long-run projections of supply, transport, storage and consumption patterns in the model region, aggregated in 5-year periods, distinguishing two seasons (winter and summer). Model results include...

In this paper, we estimate the degree of substitution between enrolment into Disability Insurance (DI) and Unemployment Insurance (UI) in the Netherlands. Starting in the 1990s many policy measures aimed at reducing DI enrolment, and increase labour force participation. We quantify whether...

In this paper, we construct and estimate a (semi-) structural model, so as to uncover the fraction of hidden unemployment in the Disability Insurance (DI) enrolment rate. For this purpose, we use longitudinal administrative data of Dutch employers for 1994-2003. We find the (average) fraction...

The Dutch welfare state is under pressure. Future trends of ageing and globalisation render public finances unsustainable and worsen the position of low-skilled workers on the labour market. At the same time, welfare state institutions seem insufficiently adapted to changed socio-cultural...

This study compares the expected retirement replacement rates of several cohorts of Dutch employees at the time of their planned retirement with the 'actual' replacement rates based on available pension records. We find that using reasonable indexation rates, the expected replacement...

This study provides the first estimates of the causal effect of time in school on cognitive skills for many countries around the world, for multiple age groups and for multiple subjects. These estimates enable a comparison of the performance of education systems based on gain scores instead of...

This paper investigates the effect of coaching in vocational education on school dropout using data from a randomized experiment. We find that one year of coaching reduces school dropout by more than 40 percent from 17 to 10 percentage points. The reduction in school dropout results from two...

This paper examines the causal link that runs from classroom quality to student achievement using data on twin pairs who entered the same school but were allocated to different classrooms in an exogenous way. In particular, we apply twin fixed-effects estimation to assess the effect of teacher...

This paper investigates the relationship between teacher evaluations, conducted by trained evaluators, and pupil performance in primary education in a large city in the Netherlands. Teacher evaluations are based on a detailed rubric containing 75 classroom practices considered to be crucial for...

This paper evaluates the effects of the raising of the minimum school leaving age (ROSLA) from 14 to 15 in the Netherlands in 1971. The policy goal was to increase the number of high school graduates. The analysis shows that the change led to a decrease in the high school dropout rate of...
