PB - National Bureau of Economic Research N1 - February 2019; Hardcopy version available to institutional subscribers N2 - We use state-of-the-art, satellite-based PM2.5 estimates to assess the extent to which the EPA's existing, monitor-based measurements over- or under-estimate true exposure to PM2.5 pollution. Treating satellite-based estimates as truth implies a substantial number of "policy errors"--over-regulating areas that comply with air quality standards and under-regulating other areas that appear to violate standards. We investigate the health implications of these apparent errors and highlight the importance of accounting for prediction error in satellite-based estimates. Uncertainty in "policy errors" increases substantially when we account for these underlying prediction errors UR - https://www.nber.org/papers/w25560 UR - http://dx.doi.org/10.3386/w25560 ER -
