RT Journal Article SR Electronic T1 What Drives Participation in State Voluntary Cleanup Programs? Evidence from Oregon JF Land Economics JO Land Econ FD University of Wisconsin Press SP 785 OP 799 DO 10.3368/le.86.4.785 VO 86 IS 4 A1 Blackman, Allen A1 Darley, Sarah A1 Lyon, Thomas P. A1 Wernstedt, Kris YR 2010 UL http://le.uwpress.org/content/86/4/785.abstract AB Virtually all U.S. states have now created voluntary cleanup programs (VCPs), offering liability relief and other incentives for responsible parties to remediate contaminated sites. We use a multinomial probit model to analyze participation in Oregon’s two VCPs. In contrast to previous VCP research, we find that these programs attract sites with significant contamination, not just clean ones. Furthermore, we find that regulatory pressure—in particular, the public listing of contaminated sites—drives participation. These findings imply Oregon has been able to spur voluntary remediation via public disclosure, a result that comports with themes in the literature on voluntary environmental regulation.
