Determinants and Effects on Property Values of Participation in Voluntary Cleanup Programs: The Case of Colorado

State Voluntary Cleanup Programs (VCPs) were established starting in the 1990s to encourage the environmental remediation and redevelopment of contaminated properties. These programs typically offer liability relief, subsidies and other regulatory incentives in exchange for site cleanup. This paper asks three questions: First, what type of properties are attracted to voluntary cleanup programs? Second, what is the interaction between these state programs and other incentives for remediation and economic development, such as Enterprise Zone and Brownfield Zone designations? Third, what is the effect of participation in the VCP on property values? We use data from Colorado’s VCP to answer these questions. We find that most of the properties enrolled in this program were not previously listed on EPA’s contaminated site registries, and that most applicants seek to obtain directly a “no further action” determination without undergoing remediation. The main determinants of participation are the size of the parcel and whether the surrounding land use is primarily residential, while other incentives have little effect. Properties with confirmed contamination sell at a 47% discount relative to comparable uncontaminated parcels, and participation tends to raise the property price, but this latter effect is not statistically significant. Taken together, these findings suggest that the participating properties are those with high development potential, and hint at the possibility that owners or developers may be seeking to obtain a clean bill of health from the State with only minimal or no cleanup efforts. Were these findings confirmed with data from other states, they would raise doubts about the effectiveness of voluntary programs in encouraging remediation and their usefulness in reversing some of the undesired effects of the Superfund legislation.Brownfields, Contaminated sites, Voluntary cleanup programs, Incentives

On and Off the Liability Bandwagon: Explaining State Adoptions of Strict Liability in Hazardous Waste Programs

We analyze factors in states' decisions to switch their approaches to hazardous waste liability policy from negligence standards to policies based on strict liability. Many, but not all, states have switched in recent years. We explain differences in the timing of states' adoption of strict liability into their "mini-superfund" programs using data on states' industrial activities, environmental programs, wealth and education, and political orientation. We test implications of a theoretical model in which states adopt the liability regime (strict versus negligence-based liability) that they see as having greater net benefits. We test this model by estimating a probit equation of the presence or absence of strict liability in a state hazardous waste cleanup program. We find that the likelihood of a state adopting strict liability is positively associated with the number of large manufacturing plants located in that state, but negatively associated with the number of large mining establishments. We also find that educational attainment of residents, state government resources, effectiveness of other state environmental programs, and political variables are significant determinants of the likelihood of strict liability adoption. Our findings suggest states may view strict liability as better suited to industrial waste sites than to mining pollution, that they may be partly motivated by a "deep pocket" mentality, or that they may anticipate engaging in "precaution targeting" (T. H. Tietenberg, 1989, Land Economics 65:4, 305-319). Non-adopters may have fewer resources available to confront environmental problems, may not wish to discourage business activity, or may have other programs in place which effectively substitute (at least for a time) for strict liability imposed on parties responsible for hazardous waste releases.

What are the Effects of Contamination Risks on Commercial and Industrial Properties? Evidence from Baltimore, Maryland

Using the hedonic pricing approach, we investigate how the information released on public registries of contaminated and potentially contaminated sites affects nearby commercial and industrial properties in Baltimore, Maryland. We find that commercial and industrial properties are virtually unaffected by proximity to a site with a history of contamination. Knowing that the site is no longer considered contaminated does not have a rebound effect on property prices either. We also find that urban economic development policies, such as Empowerment Zones and Enterprise Zones, have little effect on property values. In sum, brownfield properties in Baltimore are not particularly attractive investments for developers, and there is little potential for self-sustaining cleanup based on appropriate fiscal incentives, such as Tax Increment Financing. It is doubtful that “one size fits all” measures to encourage the cleanup of contaminated sites can be successful in this context.Contaminated sites registries, Distance to contaminated sites, Hedonic pricing model, Brownfields

Context and the VSL: Evidence from a Stated Preference Study in Italy and the Czech Republic

We report on the results of a survey based on conjoint choice experiments that was specifically designed to investigate the effect of context on the Value of a Statistical Life (VSL), an important input into the calculation of the mortality benefits of environmental policies that reduce premature mortality. We define “context” broadly to include i) the cause of death (respiratory illness, cancer, road traffic accident), ii) the beneficiary of the risk reduction (adult v. child), and iii) the mode of provision of the risk reduction (public program v. private good). The survey was conducted following similar protocols in Italy and the Czech Republic. When do not distinguish for the cause of death, child and adult VSL are not significantly different from one another in Italy, and the difference is weak in the Czech sample. When we distinguish for the cause of death, we find that child and adult VSLs are different at the 1% level for respiratory illnesses and road-traffic accidents, but do not differ for cancer risks. We find evidence of a “cancer premium” and a “public program premium.” In both countries, the marginal utility of income is about 20% lower among wealthier people, which makes the VSL about 20% higher among respondents with incomes above the sample average. The discount rate implicit in people‘s choices is effectively zero. We conclude that there is heterogeneity in the VSL, and that such heterogeneity is primarily driven by risk characteristics and mode of delivery of the risk reduction, rather than by individual characteristics of the respondent (e.g., income and education). For the most part, our results do not disagree with environmental policy analyses that use the same VSL for children and adults, and that apply a cancer premium.VSL, Conjoint Choice Experiments, Mortality Risk Reductions, Cost-benefit Analysis, Forced Choice Questions

The Value of Cultural Heritage Sites in Armenia: Evidence From a Travel Cost Method Study

This paper applies the travel cost method to visits to cultural sites in Armenia by domestic visitors. Respondents intercepted at four cultural monuments provided information on their visitation patterns, experience at the site, perception of the state of conservation of the monuments, and rating of the quality of the services and infrastructures. We combine actual trips with stated trips under hypothetical programs that would enhance the conservation of the monuments and improve one of (i) the cultural experience at the site, (ii) the quality of the infrastructure, or (iii) the quality of the services, and use the combined actual and stated trips to fit a panel data model. Our investigation shows that that there are significant use values associated with the four study monuments, and that conservation programs and initiatives that improve the cultural experience, or simply make it easier for the respondent to reach and spend time at the monument, are valued by domestic visitors and would encourage higher visitation rates.

Does the Cause of Death Matter? The Effect of Dread, Controllability, Exposure and Latency on the Vsl

The Value of a Statistical Life is a key input into the calculation of the benefits of environmental policies that save lives. To date, the VSL used in environmental policy analyses has not been adjusted for age or the cause of death. Air pollution regulations, however, are linked to reductions in the risk of dying for cancer, heart disease, and respiratory illnesses, raising the question whether a single VSL should be applied for all of these causes of death. We conducted a conjoint choice experiment survey in Milan, Italy, to investigate this question. We find that the VSL increases with dread, exposure, the respondents’ assessments of the baseline risks, and experience with the specific risks being studied. The VSL is higher when the risk reduction is delivered by a public program, and increases with the effectiveness rating assigned by the respondent to public programs that address specific causes of death. The effectiveness of private risk-reducing behaviors is also positively associated with the VSL, but the effect is only half as large as that of public program effectiveness. The coefficients on dummies for the cause of death per se—namely, whether it’s cancer, a road traffic accident or a respiratory illness—are strongly statistically significant. All else the same, the fact that the cause of the death is “cancer” results in a VSL that is almost one million euro above the amount predicted by dread, exposure, beliefs, etc. The VSL in the road safety context is about one million euro less than what is predicted by dread, exposure, beliefs, etc. These effects are large, but the majority of the variation in the VSL is accounted for by the public program feature, the effectiveness of public programs at reducing the indicated risk, and dread. The effects of exposure and experience are smaller. These results raise the question whether using VSL figures based on private risk reduction, which is usually recommended to avoid double-counting, severely understates how much a society might be willing to pay for public safety.VSL, Conjoint Choice Experiments, Mortality Risk Reductions, Cost-benefit Analysis, Forced Choice Questions

Accidents Waiting to Happen: Liability Policy and Toxic Pollution Releases

Proponents of environmental policies based on liability assert that strict liability imposed on the polluter will induce firms to handle hazardous wastes properly and to avoid disposing them into the environment. Economic theory and a few well-publicized cases, however, suggest that a number of factors may dilute the incentives posed by strict liability. In this paper, the authors run regressions relating unintended releases of pollution into the environment (aggregated at the state level, and followed over nine years from 1987 to 1995) to the imposition of strict liability on the polluter, exploiting variation across states in the liability provisions of their mini-Superfund laws, and in the years these were adopted. The authors experiment with instrumental variable estimation, fixed effects, and endogenous switching, and find that only after they explicitly model the endogeneity of states' liability laws is strict liability seen as reducing the seriousness of spills and releases. They also find evidence consistent with the notion that under strict liability, firms may spin off into, or delegate riskier production processes to, smaller firms, which are partially sheltered from liability. This tendency appears to be widespread.strict liability, negligence, hazardous waste, state environmental policy, endogenous policy adoption

Accidents Waiting to Happen: Liability Policy and Toxic Pollution Releases

Proponents of environmental policies based on liability assert that strict liability imposed on polluters induces firms to handle hazardous wastes properly. We run regressions relating unintended pollution releases to strict liability imposed on polluters, exploiting variation across states and over time in the liability provisions of state mini-Superfund laws. Strict liability reduces the frequency and severity of pollution releases, provided it is modeled endogenously with the latter. Its effects vary with firm size. Partially sheltered from liability, small firms may have specialized in riskier production processes, but their number has not necessarily grown in response to the states’ liability policy.strict liability, negligence, hazardous waste, state environmental policy, endogenous policy adoption
