We estimate the causal effects of acute fine particulate matter exposure on mortality, health care use, and medical costs among the US elderly using Medicare data and a novel instrument for air pollution: changes in local wind direction. We develop a new approach that uses machine learning to...

Prior research demonstrates that mortality rates increase during economic booms and decrease during economic busts, but little analysis has been conducted investigating the role of environmental risks as potential mechanisms for this relationship. We investigate the contribution of air pollution...

We estimate the causal effects of acute fine particulate matter (PM 2.5) exposure on mortality and health care use among the US elderly using Medicare administrative data and a novel instrument for air pollution: changes in the local wind direction. We then develop a new methodology that uses...

Prior research demonstrates that mortality rates increase during economic booms and decrease during economic busts, but little analysis has been conducted investigating the role of environmental risks as potential mechanisms for this relationship. We investigate the contribution of air pollution...

Using 20 years of data on Medicare beneficiaries, we predict the end-of-century mortality effects of climate change among the U.S. elderly, accounting at the ZIP code level for both adaptation and regional heterogeneity in the temperature-mortality relationship. We find that this relationship...
