Abstract: While shale gas development can result in rapid local economic development, negative externalities associated with the process may adversely affect the prices of nearby homes. We utilize a difference-in-differences estimator with additional controls for house fixed effects and the boundary of the public water service area in Washington County, Pennsylvania to identify the capitalization of groundwater contamination risk in property values, differentiating it from other externalities, lease payments to homeowners, and local economic development. We find that proximity to wells increases property values. However, groundwater contamination concerns fully offset those gains by reducing property values up to 26 percent.

Abstract: The environmental remediation required to permanently decommissionmost industrial projects is an expensive and irreversible investment. Real options literature shows that temporarily closing a project and postponing decommissioning has value when economic conditions are uncertain and future reactivation is possible. However, high decommissioning costs create an incentive to “temporarily” close a project, even when there is no intention to reactivate. This paper estimates a dynamic discrete choice model of closure to evaluate the likelihood of reactivation. The model reveals that the option to temporarily close is being widely used to avoid environmental remediation of oil and gas wells in Canada.

Abstract: Using advances in text analysis, we examine the content and timing of21,493 press releases issued by the U.S. Environmental Protection Agency (EPA) between 1994 and 2009. Press releases announcing enforcement actions or regulatory changes were issued more often on Fridays and before holidays, a time when news has the least impact on media coverage and financial markets. Changing the timing of press releases may increase deterrence through awareness of regulation and market reaction to environmental news. We find no evidence of regulatory capture. We compare text analysis techniques that allow data collection from sources previously too expensive to access.

Abstract: This paper reports on a preliminary analysis of performance indicators on 3,020 platforms operating in the Gulf of Mexico between 1996 and 2010. Statistical analysis reveals that companyreported incidents (such as blowouts, fires, injuries, and pollution) increase with water depth, controlling for platform characteristics such as age, quantity of oil and gas produced, and number of producing wells. In addition to company-reported incidents, we examine government inspections and the type ofenforcement action (warning, component shut-in, facility shut-in, or civil penalty review) following an inspection. Fewer incidents of noncompliance are detected during inspections on deepwater platformscompared with shallow-water platforms; however, the magnitude of the effect of depth on noncompliance is not large. We provide a preliminary analysis of the effect of prior findings of noncompliance, suggesting that noncompliance is persistent. We also find significant variability in both self-reported incidents and noncompliance across leaseholders.
