| Abstract: | This paper uses event study methods to estimate wealth effects upon shareholders who are named by the U.S. Environmental Protection Agency (EPA) as potentially responsible parties at a Superfund site. Impacts appear to be divided into three periods: an initial program period where stock market effects depend largely on prior visibility of the site, a second period where likely financial impact is more important, and a third period where notification has little association with either visibility or financial measures. However, the expected remediation cost burden is not borne evenly. "Deep-pocket" firms appear to be disproportionately penalized by the market during the second period. |
