Hassles and Environmental Health Screenings: Evidence from Lead Tests in Illinois.

I study the determinants of childhood lead screening using all Illinois birth records (2001–2014) matched to lead testing records and geocoded housing age data. Housing age measures lead risk, as older houses disproportionally have lead paint. Changes in geographic access to providers provide variation in nonmonetary costs of testing. Higher costs reduce screening among low- and high-risk households alike. Thus, self-selection based on screening costs does not appear to improve targeting, even though high-risk households are willing to pay $31–419 more than low-risk households for screening. Screening incentives would be cost-effective for reasonable values of lead poisoning externalities. [ABSTRACT FROM AUTHOR]
