This study comprehensively assesses the immediate effects of extreme weather conditions and high concentrations of ambient air pollution on population health. For Germany and the years 1999 to 2008, we link the universe of all 170 million hospital admissions, along with all 8 million deaths,...

Exposure to smoggy days is a common part of urban life, but can be avoided by vulnerable populations with municipal investment in warnings. This paper provides the first evidence on the long-term effects of early exposure to smog. Variation comes from exposure to the Great London Smog of 1952....

We examine the impact of air pollution on infant death in California over the 1990s. Our work offers several innovations: First, many previous studies examine populations subject to far greater levels of pollution. In contrast, the experience of California in the 1990s is clearly relevant to...

Emergency department visits are costly to providers and to patients. We use the Flint water crisis to test if an increase in office visits reduced avoidable emergency room visits. In September 2015, the city of Flint issued a lead advisory to its residents, alerting them of increased lead levels...

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...

We implement a mixed method approach that combines a randomized controlled trial and qualitative data collection to assess whether, and if so how, behavioural change can be sustained. We do so in the context of Pakistan's national sanitation strategy to combat open defecation, Community-Led...

In this paper, we study the effect of fine particulate matter (PM 2.5) exposure on Emergency Room (ER) visits in Chile. Our identification strategy exploits daily PM 2.5 variation within a hospital-month-year combination. Unlike previous papers, our data allow us to study the impact of high...

In this paper, we study the short-term effect of fine particulate matter (PM 2.5) exposure on respiratory Emergency Room (ER) visits in Chile, a middle-income country with high levels of air pollution. To instrument for PM 2.5 we use wind speed at different altitudes (pressure levels). Unlike...
