I’m excited to see my work on how place shapes health outcomes featured in AEA chart of the week
2 Dec 2020
Your choice of where to live affects more than personal finances and lifestyle—it can actually have an impact on your long-term health, say @TDeryugina and @davidmolitor in today's #ChartOfTheWeek aeaweb.org/research/charts/k…

Does cleaning up drinking water save lives?
New paper: We link US federal drinking water investments to Medicare records and find they reduce mortality among older Americans, with benefit/cost ratio >20.
Thread on what we did...

How do you measure drinking water pollution in America?
Turns out: with a lot of FOIA requests.
Our new working paper assembles a national database of U.S. drinking water pollution concentrations.
Here's what it took 🧵

9/ Caveats:
We measure mortality for ages 65 ; effects on younger ages are imprecise in county data that is not linked to specific systems.
We don't observe cause of death in Medicare.
Benefits likely extend beyond mortality. Our estimates are probably a lower bound.

10/ Bottom line: Federal drinking water investments pass a cost-benefit test by a wide margin.
This is useful to know as policymakers debate infrastructure spending.

A straight reject denies the authors a second chance, which may matter especially for authors from less resourced places. A revise-and-resubmit gives expectations that may be too high. From what I see, roughly 50% of reject-and-resubmits convert.

Recession-induced entry into disability Insurance reflects reduced opportunity costs, not worsening health. Just Accepted new paper by Colleen Carey, Nolan Miller, and David Molitor (@davidmolitor). zurl.co/8lj93

Regular health screenings are a critical component of preventive care. In a multi-wave field experiment, Damon Jones, @davidmolitor, and @JulianReif find that financial incentives increase participation in screenings both immediately & in the long term.
