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,...

Although at least 400 million people suffer from seasonal allergies worldwide, the adverse effects of pollen on "non-health" outcomes, such as cognition and productivity, are relatively understudied. Using ambulance archives from Japan, we demonstrate that high pollen days are associated with...

In 2020, Japan introduced a comprehensive heat-health warning system where daily alerts were issued by region when forecasted wet bulb globe temperature (WBGT) exceeded a threshold (33 °C). Utilizing plausibly exogenous region-day variation in the difference between actual and forecasted WBGT...

We provide evidence that lower fertility can simultaneously increase income per capita and lower carbon emissions, eliminating a trade-off central to most policies aimed at slowing global climate change. We estimate the effect of lower fertility on carbon emissions accounting for the fact that...

What do markets for voluntary climate protection imply about people's valuations of en- vironmental protection? I study this question in a large-scale field experiment (N=255,000) with a delivery service, where customers are offered carbon offsets that compensate for emissions. To estimate...

This paper studies how in utero exposure to a large-scale climate adaptation program affects birth outcomes. The program built around one million cisterns in Brazil's poorest and driest region to promote small-scale decentralized rainfall harvesting. Access to cisterns during early pregnancy...

We develop a unifying approach to estimating climate impacts and adaptation, and apply it to study the impact of climate change on local air pollution. Economic agents are usually constrained when responding to daily weather shocks, but may adjust to long-run climatic changes. By exploiting...

This paper establishes a simple theoretical framework which comprises key forces that shape the structure and interrelation of cities to study the interdependencies between urban evolution and the environment. We focus on the potential of the unfettered market forces to economize on emissions. A...
