Enforcement and Over-Compliance

Economists generally view environmental enforcement as a tool to secure compliance with regulations. This paper demonstrates that credible enforcement significantly increases statutory overcompliance with regulations as well. We find that many plants with discharges typically below legally permitted levels reduce discharges further when regulators issue fines, even on other plants. Also, likely non-compliant plants often respond to sanctions by reducing discharges well beyond reductions required by law. Thus, increased enforcement generates substantial discharge reductions above and beyond those expected from simply deterring violations.Over-compliance; Fines; Compliance; Enforcement; Regulation; Pollution Policy

Enforcement and Environmental Compliance: A Statistical Analysis of the Pulp and Paper Industry

This paper explores empirically the impact of changes of enforcement efforts on environmental compliance. Our strategy is to link observed fines and other enforcement actions to subsequent compliance behavior. We find that, on the margin, the impact of a fine for water pollutant violations is about a two-thirds reduction in the statewide violation rate in the year following a fine. This surprisingly large result obtains through the regulator’s enhanced reputation. We find that the deterrence impact on other firms in a state is almost as strong as the impact on the sanctioned firm. In contrast to fines, non-monetary sanctions contribute no detected impact on compliance.Fines, Reputation, Pollution, Compliance, Enforcement

Information Disclosure Policies: Evidence from the Electricity Industry

A “third wave” of environmental policy has recently emerged that emphasizes information provision as an integral part of the risk mitigation strategy. While theory suggests information programs may correct market failures and improve welfare, the empirical effectiveness of these programs remains largely undetermined. We show that mandatory information disclosure programs in the electricity industry achieve stated policy goals. We that the average proportion of fossil fuels decreases and the average proportion of clean increases in response to disclosure programs. However, the programs also produce unintended consequences. Customer composition and pre-existing fuel mix significantly affect program response, suggesting that effective information disclosure policies may not be efficient.disclosure, information, fuel mix, electric utilities

Regulator reputation, enforcement, and environmental compliance

This paper explores empirically the impact of enforcement efforts on environmental compliance, focusing on the role of regulator reputation spillover effects. We find that, on the margin, the impact of a fine for water pollutant violations is about a two-thirds reduction in the statewide violation rate in the year following a fine. This large result obtains through the regulator’s enhanced reputation; the deterrence impact on other plants in a state is almost as strong as the impact on the sanctioned plant. Focusing only on the response of the sanctioned plant, as in previous studies, may therefore seriously underestimate the efficacy of fines and other sanctions. This paper also examines the relative effectiveness of monitoring and enforcement instruments. Non-monetary sanctions contribute no detected impact on compliance, and the marginal fine induces substantially greater compliance than the marginal inspection

Mercury advisories: Information, education, and fish consumption

This paper examines responses to a national FDA advisory that urged at-risk individuals to limit store-bought fish consumption due to the dangers of methyl-mercury. We investigate consumer response using both parametric and nonparametric methods. Some targeted consumers significantly reduced canned fish purchases as a result of the advisory, suggesting that information-based policies can achieve the issuing agency’s goals. Education and newspaper readership were important determinants of response, suggesting that information acquisition and assimilation are key factors for risk avoidance. While some groups reduced consumption as a result of the advisory, we do not find a response among the relatively large group of at-risk households which met neither the education nor readership criteria. The advisory also had unintended spillover effects; some consumers not considered at-risk reduced consumption in response to the advisory.mercury; health information; health advisory; environmental health; fish consumption; children’s health; environmental risk; pollution;

Effects of the private-label invasion in food industries

Using supermarket scanner data, we test a variety of hypotheses from trade journals about the invasion of private-label food products. According to conventional industry wisdom, name-brand firms defended their brands against new private-label products by lowering their prices, engaging in additional promotional activities, and increasingly differentiating their products. Our empirical evidence is inconsistent with these beliefs.private label; entry; price; promotional activity; differentiation; supermarket

The Public Resource Management Game

Use of public resources for private economic gain is a longstanding, contested political issue. Public resources generate benefits beyond commodity uses, including recreation, environmental and ecological conservation and preservation, and existence and aesthetic values. We analyze this problem using a dynamic resource use game. Low use fees let commodity users capture more of the marginal benefit from private use. This increases the incentive to comply with government regulations. Optimal contracts therefore include public use fees that are lower than private rates. The optimal policy also includes random monitoring to prevent strategic learning and cheating on the use agreements and to avoid wasteful efforts to disguise noncompliant behavior. An optimal policy also includes a penalty for cheating beyond terminating the use contract. This penalty must be large enough that the commodity user who would gain the most from noncompliance experiences a negative expected net return.Renewable resources, public resources policy, optimal contracts

Are Mercury Advisories Effective? Information, Education, and Fish Consumption

This paper examines responses to a national FDA advisory urging at-risk individuals to limit store-bought fish consumption due to the dangers of methyl-mercury. We address this issue using parametric and nonparametric methods, including recently developed tests of stochastic dominance. Both education and newspaper readership were important determinants of consumption response, suggesting that information acquisition and assimilation are key factors for risk avoidance. While the advisory was effective for some groups, we do not find a response among the relatively large group of at-risk households which met neither the education nor readership criteria.
