Notes: The table reports the coefficients and standard errors (in square brackets) associated with Closeijt*Duringijt and Closeijt*Afterijt from the estimation of alternative versions of equation (1). Standard errors are clustered at the county-year level. The sample is limited to singleton births within 5,000 meters of a site conceived between 4 years prior to the initiation of a cleanup and 4 years after completion are included. “Close” is defined as within 2000 meters of the site. Regressions include controls for race, maternal age, maternal education, maternal smoking, child parity, child gender, year of birth, and zip code.
indicate significance at the 90%, 95%, and 99% levels. See the text for further details.
