Influenced by models of optimal law enforcement, several authors have recently revised the work on efficient levels of regulatory control to accommodate the realities of underenforcement and imperfect compliance. However, most of these efforts have centered on either the enforcement agency or the firm and have largely ignored the decentralized nature of the enforcement process. This paper extends these results by modelling both the firm and the local agency and by incorporating detection uncertainty and concealment activity. Each model is then evaluated with respect to the alternative regulatory regimes of direct controls and emission taxes. 相似文献

Data from 1,122 brine injection wells, 24,515 dry holes, 20,877 plugged oil/gas wells, and 256 water wells were mapped with a geographic information system (GIS) and statistically analyzed. There were 9, 107, and 58 water wells within 750 m of a brine injection well, dry hole, or plugged oil/gas well, respectively. Computed median concentrations were 157 mg/l for chloride, 0.8 mg/l for bromide, and 169 microg/l for barium. The maximum chloride concentration was 2,384 mg/l, close to 10 times the secondary drinking water standard. Shallow water wells and water wells near plugged oil/gas wells had significantly higher chloride and bromide levels. 相似文献
