Exceeding the Threshold: Analysis of Public Information Transfer using Instrumental Variables
By Gabrielle Inder
This paper examines how information transfer about contamination levels found at brownfield sites capitalizes into nearby property values. More specifically, a hedonic model is used to test the impact on housing transaction prices when a binary measure (i.e. exceeding a threshold or not) or a continuous measure (i.e. chemical levels) is used. In the analysis, I exploit the variation in the contaminant thresholds, caused by regulatory conditions defined by the state of Massachusetts, holding the contaminant level constant. As thresholds are tied to neighborhood attributes in areas surrounding brownfields, threshold exceedance is potentially correlated to unobserved factors that impact housing values. An instrumental variables approach is used to create variation in threshold
exceedance through the use of an instrument that measures the presence to underground aquifers. After instrumenting for threshold exceedance, my estimates indicate that a 10.8% decrease in housing values occurs when a contaminant threshold is exceeded, while the continuous measures of toxicity indicate a negative but insignificant effect. These findings suggest that policy makers should consider information conveyance when creating policies to inform homeowners of pollution presence, as improved information provision may increase public awareness about local environmental concerns.

The Role of Income in Environmental Justice: A National Analysis of Race, Housing Markets, and Air Pollution
By Christopher Brown
Historically, evidence has shown that minority populations in the United States suffer a disproportionate burden of pollution compared to whites. This study examines whether this burden could be the result of income disparities between whites and minorities, acting through the housing market. We look at 324 Metropolitan Statistical Areas (MSA’s) in the United States as defined by the Economic and Social Research Institute. Using demographic data from the 2000 Decennial Census and pollution data from the 1999 national Air Toxic Assessments, we compare the race-income correlation in each MSA for four races (white, black, Latino, and Asian) with the race-income.

The Financial Impact of the Oil Pollution Act: Do the Penalties Resulting from Oil Spills Fulfill the Purpose of the OPA?
by Melissa Keever
Abstract
This paper explores the financial impact of the Oil Pollution Act (OPA) on oil companies for oil spills. Total penalty per barrel, including civil and criminal penalties, and total cost per barrel for oil spills are analyzed prior OPA and post OPA. Difference-in-differences estimation is used to determine if penalties and costs for an oil spill increased post OPA in accordance with the purpose of the OPA to hold companies more financially responsible for oil spills, especially damaging ones. With the exception of criminal penalty per barrel, the analysis suggests that the OPA is not achieving the desired financial impact.
