This paper examines weight loss and the formation of healthy habits through cash rewards in the context of a multi-phase randomized controlled trial involving 700 obese individuals. We find effects of monetary incentives for weight loss of up to EUR 300 on body weight during all experimental...

This paper uses microdata from Brazilian vital statistics natality and mortality data between 2000 and 2010 to estimate the impact of in-utero exposure to local violence -measured by homicide rates- on birth outcomes. Focusing on small communities, where it is more plausible that local homicide...

We show that children who are born at or just before the weekend are less likely to be breastfed, owing to poorer breastfeeding support services in hospitals at weekends. We use this variation to estimate the effect of breastfeeding on children’s development in the first five years of life,...

The current coronavirus pandemic is an unprecedented public health challenge that has devastating economic impacts for households. Using a sample of 230,540 respondents to online surveys in 17 countries in Latin America and the Caribbean, we show that the economic impacts are large and unequal:...

Using a randomized field experiment, we show that health care specialists cream-skim patients by their expected profitability. In the German two-tier system, outpatient reimbursement rates for both public and private insurance are centrally determined but are more than twice as high for the...

This paper investigates the short-term effects of public smoking bans on individual smoking behavior. In 2007 and 2008, state-level smoking bans were gradually introduced in all of Germany’s sixteen federal states. We exploit this variation in the timing of state bans to identify the effect...

This paper attempts to identify the climatic effect on birth outcomes in Brazil and, thus, to predict the potential impact of climate change. Panel data models indicate that excess and lack of rainfall have the most important harmful effects on newborns' health; temperature stresses and low...

This paper leverages a discontinuity in legal access to alcohol at age 16 to estimate its impacts on teenage drinking and crime in Germany, a country with very high consumption levels. Using detailed survey data and administrative crime records from 2005 to 2015, I detect considerable increases...

We estimate the causal impact of school smoking bans in Germany on the propensity and intensity of smoking. Using representative longitudinal data, we use variation in state, year, age cohort, school track, and survey time for implementation of such smoking bans to identify the effects of...
