In this paper, I examine the impact of uninsured patients on the health of the insured, focusing on one health outcome - the in-hospital mortality rate of insured heart attack patients. I employ panel data models using patient discharge and hospital financial data from California (1999-2006). My...

We examine the impact of new medical information on drug safety on preventive health behavior. We exploit the release of the findings of the Women's Health Initiative Study (WHIS) - the largest randomized controlled trial of women's health - which demonstrated in 2002 that long-term Hormone...

We investigate the spillover effects of early-life medical treatments on the siblings of treated children. We use a regression discontinuity design that exploits changes in medical treatments across the very low birth weight (VLBW) cutoff. Using administrative data from Denmark, we first confirm...

Many developed countries have recently experienced sharp increases in home birth rates. This paper investigates the impact of home births on the health of low-risk newborns using data from the Netherlands, the only developed country where home births are widespread. To account for endogeneity in...

We test whether financial incentives have an effect on weight reduction in a randomized controlled trial involving 700 obese persons assigned to three experimental groups. While two treatment groups obtain €150 and €300, respectively, for achieving an individually assigned target weight...

We investigate the impact of obstetrician supervision, as opposed to midwife supervision, on the short-term health of low-risk newborns. We exploit a unique policy rule in the Netherlands that creates a large discontinuity in the probability of a low-risk birth being attended by an obstetrician...

We investigate the impact of early-life medical interventions on low-risk newborn health. A policy rule in The Netherlands creates large discontinuities in medical treatments at gestational week 37. Using a regression discontinuity design, we find no health benefits from additional treatments...

We examine the persistence of the impact of early-life exposure to air pollution on children's health from birth to school enrollment using administrative public health insurance records covering one third of all children in Germany. For identification, we exploit air quality improvements caused...

We use event-study models based on staggered summer vacations in Germany to estimate the effect of school re-openings after the summer of 2021 on the spread of SARS-CoV-2. Estimations are based on daily counts of confirmed coronavirus infections across all 401 German counties. Our results are...

We study the impact of short-term exposure to ambient air pollution on the spread and severity of COVID-19 in Germany. We combine data on county-by-day level on confirmed cases and deaths with information on local air quality and weather conditions and exploit short-term variation in the...
