Does it matter when a child starts school? While the popular press seems to suggest it does, there is limited evidence of a long-run effect of school starting age on student outcomes. This paper uses data on the population of Norway to examine the role of school starting age on longer-run...

Using a large population-based dataset, we estimate a substantial intergenerational transmission of IQ scores; a 10% increase in father's score at age 18 is associated with a 3.2% increase in son's score. This relationship also holds true for various subpopulations.

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...

Among the perceived inputs in the "production" of child quality is family size; there is an extensive theoretical literature that postulates a tradeoff between child quantity and quality within a family. However, there is little causal evidence that speaks to this theory. Our analysis is able to...
