This paper introduces a new IV strategy based on IVF induced fertility variation in childless families to estimate the causal effect of having children on female labor supply using IVF treated women in Denmark. Because observed chances of IVF success do not depend on labor market histories, IVF...

We introduce a novel strategy to study the intergenerational transmission of human capital, net of genetic skill transfers. For this purpose, we use unique data on children conceived through sperm and egg donation in IVF treatments in Denmark. Because the assignment of donors is not selective,...

A substantial and growing fraction of children across Europe and the US live in single parent households. Law practices are evolving to encourage both parents to maintain contact with their children following parental separation/divorce, driven by the belief that such contact is in the best...

From 2011 to 2013 a randomized controlled trial has been run in Danish preschools to obtain evidence on improvements of early childhood education by providing training to the preschool teachers. The purpose of the intervention is to improve child socio-emotional outcomes (measured by SDQ),...

We conduct a study under 2,400 third grade students at three large secondary comprehensive schools to evaluate a gifted and talented (GT) program with selective program admission based on past achievement. We construct three complementary estimates of the program's impact on student achievement....

This paper examines whether gay and lesbian workers sort into tolerant occupations. With information on sexual orientation, prejudice and occupational choice taken from Australian Twin Registers, we find that gays and lesbians shy away from prejudiced occupations. We show that our segregation...

In this paper we examine the effect of birth order on human capital development in Ecuador using a large national database together with self-collected survey data. Using family fixed effects models we find significant positive birth order effects; earlier born children stay behind in their...

We estimate the impact of changes in unearned income on the height and weight of young children in a developing country. As source of variation we use changes in the eligibility criteria for receipt of an unconditional cash transfer in Ecuador. Two years after families lost the transfer, which...

There exists a strong educational gradient in cancer risk, which has been documented in a wide range of populations. Yet relatively little is known about the extent to which education is causally linked to cancer incidence and mortality. This paper exploits a large social experiment where an...

Recent studies that aim to estimate the causal link between the education of parents and their children provide evidence that is far from conclusive. This paper explores why. There are a number of possible explanations. One is that these studies rely on different data sources, gathered in...
