This paper studies the effects of day care exposure on behavioral problems and mental health as well as on various aspects of physical health, at various ages during childhood. We draw on a unique set of comprehensive individual-level out-patient and inpatient health care register data from...

This paper studies the effects of day care exposure on behavioral disorders and mental and physical health at various ages during childhood. We draw on a unique set of merged population register data from Sweden over the period 1999-2008. This includes merged information at the individual level...

Empirical analyses of twin mortality often use models with dependent unobserved frailty terms capturing genetic and childhood environmental determinants. This ignores that mortality rates can be co-dependent due to bereavement effects, i.e. to a time-dependent causal effect of the loss of the...

This is the first study to analyze effects of in utero exposure to the severe Dutch Hunger Winter famine (1944/45) on labor market outcomes and hospitalization. This famine is clearly demarcated in time and space. It was not anticipated. Nutritional conditions were stable before and after the...

The Dutch Hunger Winter (1944/45) is the most-studied famine in the literature on long-run effects of malnutrition in utero. Its temporal and spatial dermacations are clear, it was severe, it was anticipated, and nutritional conditions in society were favorable and stable before and after the...

The Dutch Hunger Winter (1944/45) is the most-studied famine in the literature on long-run effects of malnutrition in utero. Its temporal and spatial demarcations are clear, it was severe, it was not anticipated, and nutritional conditions in society were favorable and stable before and after...

We analyze interaction effects of birth weight and the business cycle at birth on individual cardiovascular (CV) mortality later in life. In addition, we examine to what extent these long-run effects run by way of cognitive ability and education and to what extent those mitigate the long-run...

We examine a new general class of hazard rate models for survival data, containing a parametric and a nonparametric component. Both can be a mix of a time effect and (possibly time-dependent) marker or covariate effects. A number of well-known models are special cases. In a counting process...
