Shimshack Paper Published in Science Magazine, Garners National Attention

PM2.5 air pollution has fallen substantially in the past four decades, yet relative disparities still persist throughout the United States.  That is the key finding from a paper published in the July 31 issue of Science magazine, written by Batten School Associate Dean for Academic Affairs Jay Shimshack.  The paper, co-written with UVA Assistant Professor of Economics Jonathan Colmer, Ian Hardman from Stanford University’s Program on Energy and Sustainable Development, and John Voorheis, an economist at the U.S. Census Bureau, has quickly earned national attention. 

PM2.5 is a form of particulate matter air pollution characterized by fine inhalable particles with diameters that are generally 2.5 micrometers and smaller.  This type of air pollution has adverse effects on health, wealth, and productivity.  In “Disparities in PM2.5 Air Pollution in the United States,” the authors found that the most polluted areas in 1981 are still the most polluted areas today; conversely, the least polluted areas in 1981 remain the least polluted areas today.  Further, areas that were or became whiter and richer between 1981 and 2016 have become relatively less polluted over time.
