We find that environmental insurance can achieve social efficiency even when two traditional policy instruments—ex post fines and risk management mandates with ex ante fines—do not. Inefficiency occurs with ex post fines, when small firms declare bankruptcy and escape their liabilities, limiting the incentives from this policy tool. Firms ignore mandates to implement efficient risk management because regulatory agencies do not have sufficient resources to monitor every firm. The evolution of the U.S. Environmental Protection Agency’s and states’ underground storage tank programs suggests that mandating environmental insurance can address inefficiency due to small firms declaring bankruptcy. Comparing insurance mandates to risk management mandates, the burden on a regulator is lower if all it has to do is to confirm that the firm has insurance rather than that the firm has actually, and effectively, implemented required management practices. For underground storage tanks, we show that insurance lowered toxic releases.

 

To Err on Humans is not Benign: incentives for adoption of medical error-reporting systems

PDF link iconConcerns about frequent and harmful medical errors have led policy makers to advocate the creation of a system for medical error reporting. Health providers, fearing that reported information about errors would be used against them under the current medical malpractice system, have been reluctant to participate in such reporting systems.We propose a re-design of the malpractice system – one in which penalties are a function of the health provider’s reporting efforts – to overcome this incentive problem.We also consider some alternatives to this mechanism that address two important ways in which reporting effort may not be observable: hospitals may have interests distinct from individual physicians and may not be able to observe their reporting efforts, and a regulatory agency or a court may not be able to adequately observe reporting efforts by a provider.
