There is an extensive theoretical literature that postulates a trade-off between child quantity and quality within a family. However, there is little causal evidence that speaks to this theory. Using a rich data set on the entire population of Norway over an extended period of time, we examine...

Parents with higher education levels have children with higher education levels. However, is this because parental education actually changes the outcomes of children, suggesting an important spillover of education policies, or is it merely that more able individuals who have higher education...

More able parents tend to have more able children. While few would question the validity of this statement, there is little large-scale evidence on the intergenerational transmission of IQ scores. Using a larger and more comprehensive dataset than previous work, we are able to estimate the...

This paper examines the causal relationship between parents' education and that of their children in Norway. In 1959, the Norwegian Parliament legislated a mandatory school reform. In addition, the reform standardized the curriculum and increased access to schools, since the nine years of...

I use panel data to examine whether long-term changes in industry wages are positively related to long-term changes in industry employment. Previous research using repeated cross-sectional data found no systematic relationship between these variables. Using standard fixed effects models to deal...

In this paper, we compile a unique historical dataset that records strike activity in the British engineering industry from 1920 to 1970. These data have the advantage of containing a fairly homogenous set of companies and workers, covering a long period with varying labour market conditions,...

Lower birth weight babies have worse outcomes, both short-run in terms of one-year mortality rates and longer run in terms of educational attainment and earnings. However, recent research has called into question whether birth weight itself is important or whether it simply reflects other...

While recent research finds strong evidence that birth order affects children’s outcomes such as education and earnings, the evidence on the effects of birth order on IQ is decidedly mixed. This paper uses a large dataset on the population of Norway that allows us to precisely measure birth...

Do students benefit from compulsory schooling? Researchers using changes in compulsory schooling laws as instruments have typically estimated very high returns to additional schooling that are greater than the corresponding OLS estimates and concluded that the group of individuals who are...

Based on the methodology of Beaudry and DiNardo (1991), this paper investigates the relative importance of the spot market and implicit contracts in the determination of British real wages. Empirical work is carried out separately for males and females with individual level data taken from the...
