Numerous studies have evaluated the effect of nutrition early in life on health much later in life by comparing individuals born during a famine to others. Nutritional intake is typically unobserved and endogenous, whereas famines arguably provide exogenous variation in the provision of...

With ageing populations and a stronger reliance on individual financial decision-making concerning asset portfolios, retirement schemes, pensions and insurances, it becomes increasingly important to understand the determinants of cognitive ability among the elderly. To study effects of the...

Although learning-by-doing is believed to be an important source of productivity growth, there is limited evidence that production volume affects productivity in a causal sense. We document evidence of learning-by-doing in a highly skilled profession where stakes are high; advanced cancer...

We identify the ages that constitute critical periods in children’s development towards their adult health status. For this we use data on families migrating into Sweden from countries that are poorer, with less healthy conditions. Long-run health is proxied by adult height. The relation...

This paper utilizes a Swedish alcohol policy experiment conducted in the late 1960s to identify the impact of prenatal alcohol exposure on educational attainments and labor market outcomes. The experiment started in November 1967 and was prematurely discontinued in July 1968 due to a sharp...

We compare the income and wage trajectories of women in relation to their male partners before and after parenthood. Focusing on the within-couple gap allows us to control for both observed and unobserved attributes of the spouse and to estimate both short-and long-term effects of entering...

We extend the standard evaluation framework to allow for interactions between individuals within segmented markets. An individual’s outcome depends not only on the assigned treatment status but also on (features of) the distribution of the assigned treatments in his market. To evaluate how the...

Abadie and Imbens (2008, Econometrica) showed that classical bootstrap schemes fail to provide correct inference for K-nearest neighbour (KNN) matching estimators of average causal effects. This is an interesting result showing that bootstrap should not be applied without theoretical...

This paper evaluates the effects of a major Swedish school choice reform. The reform in 1992 increased school choice and competition among public schools as well as through a large-scale introduction of private schools. We estimate the effects of school choice and competition, using precise...

In this study, we estimate the effects of three targeted labour market programmes (LMPs) on the labour market outcomes of occupationally disabled job seekers. Using propensity score matching, we estimate the average treatment effect on the treated of wage subsi-dies, sheltered public employment,...
