Information Asymmetries, Uncertainties, and Cleanup Delays at Superfund Sites

Superfund cleanup has been extremely slow. Traditional analysis has centered around reducing negotiation and litigation to expedite the cleanup process. We investigate other factors which provide possible incentives for delay, namely, discounting, risk aversion, and compensation for off-site damage. We find that liability share plays an essential role in PRPsʹ incentives to delay. Commonly adopted EPA strategies, such as negotiating with PRP steering committees and buying outde minimisPRPs, may also lead to delay. The paper also designs a Bayesian mechanism for information extraction, and finds that the lump-sum transfer mechanism is not always efficient.
