Green Markets and Private Provision of Public Goods

This paper develops a general model of private provision of a public good that includes the option to consume an impure public good. I use the model to investigate positive and normative consequences of “green markets.” Green markets give consumers a new choice: instead of simply consuming a private good and making a donation to an environmental public good, consumers can purchase an impure public good that produces characteristics of both activities jointly. Many governments, nongovernmental organizations, and industries promote green markets as a decentralized mechanism of environmental policy. Nevertheless, I show that under quite reasonable assumptions, green markets can have detrimental e€ects on both environmental quality and social welfare. I then derive conditions that are su¢cient to rule out such unintended consequences. The analysis applies equally to non-environmental choice settings where the joint products of an impure public good are also available separately. Such choice settings are increasingly prevalent in the economy, with impure public goods ranging from socially-responsible investments to commercial activities associated with charitable fund-raising.Public Goods

Voluntary Provision of Public Goods for Bads: A Theory of Environmental Offsets

This paper examines voluntary provision of a public good that is motivated, in part, to compensate for other activities that diminish the public good. Markets for environmental offsets, such as those that promote carbon neutrality to minimize the impact of climate change, provide an increasingly salient example. An important result, related to one shown previously, is that mean donations to the public good do not converge to zero as the economy grows large. Other results are new and comparable to those from the standard model of a privately provided public good. The Nash equilibrium is solved explicitly to show how individual direct donations and net contributions depend on wealth and heterogenous preferences. Comparative static analysis demonstrates how the level of the public good and social welfare depend on the technology, individual wealth, and an initial level of the public good. Application of the model in an environmental context establishes a starting point for understanding and making predictions about markets such as those for carbon offsets.

Impure Public Goods and the Comparative Statics of Environmentally Friendly Consumption

This paper develops an impure public good model to analyze the comparative statics of environmentally friendly consumption. “Green” products are treated as impure public goods that arise through joint production of a private characteristic and an environmental public characteristic. The model is distinct from existing impure public good models because it considers the availability of substitutes. Specifically, the model accounts for the way that the jointly produced characteristics of a green product may be available separately as well—through a conventional-good substitute, direct donations to improve environmental quality, or both. The analysis provides a theoretical foundation for understanding how demand for green products and demand for environmental quality depend on market prices, green-production technologies, and ambient environmental quality. The comparative static results generate new insights into the important and sometimes counterintuitive relationship between demand for green products and demand for environmental quality.impure public goods; green products; environmental quality

A Free Lunch in the Commons

We derive conditions under which cost-increasing measures -- consistent with either regulatory constraints or fully expropriated taxes -- can increase the profits of all agents active within a common-pool resource. This somewhat counterintuitive result is possible regardless of whether price is exogenously fixed or endogenously determined. Consumers are made no worse off and, in the case of an endogenous price, can be made strictly better off. The results simply require that total revenue be decreasing and convex in aggregate effort, which is an entirely reasonable condition, as we demonstrate in the context of a renewable natural resource. We also show that our results are robust to heterogeneity of agents and, under certain conditions, to costless entry and exit. Finally, we generalize the analysis to show its relation to earlier work on the effects of raising costs in a model of Cournot oligopoly.

Conservation Behavior: From Voluntary Restraint to a Voluntary Price Premium

This paper provides a theoretical and empirical investigation of conservation behavior that is motivated by concern for the environment. Two types of behavior are considered. First, individuals who care about environmental quality may voluntarily restrain their consumption of goods and services that generate a negative externality. Second, individuals may choose to pay a voluntary price premium for goods and services that are more "environmentally friendly." A theoretical model highlights the relationship between such voluntary restraint and a voluntary price premium. We test predictions of the model in an empirical study of household electricity consumption with introduction of a price-premium, green-electricity program. We find evidence of voluntary restraint and its relation to a voluntary price premium. The empirical results are consistent with the model of conservation behavior, as none of the theoretical predictions can be rejected.Consumer, Electricity, Environment, Households, Individual

Should We Drill in the Arctic National Wildlife Refuge? An Economic Perspective

This paper provides model-based estimates of the value of oil in Alaska's Arctic National Wildlife Refuge (ANWR). The best estimate of economically recoverable oil in the federal portion of ANWR is 7.06 billion barrels of oil, a quantity roughly equal to US consumption in 2005. The oil is worth $374 billion ($2005), but would cost $123 billion to extract and bring to market. The difference,$251 billion, would generate social benefits through industry rents of $90 billion as well as state and federal tax revenues of$37 billion and $124 billion, respectively. A contribution of the paper is the decomposition of the benefits between industry rents and tax revenue for a range of price and quantity scenarios. But drilling and development in ANWR would also bring about environmental costs. These costs would consist largely of lost nonuse values for the protected status of ANWR's natural environment. Rather than estimate these costs and conduct a benefit-cost analysis, we calculate the costs that would generate a breakeven result. We find that the average breakeven willingness to accept compensation to allow drilling in ANWR ranges from$582 to $1,782 per person, with a mean estimate of$1,141.

Explaining the Price of Voluntary Carbon Offsets

This paper investigates factors that explain the large variability in the price of voluntary carbon offsets. We estimate hedonic price functions using a variety of provider- and project-level characteristics as explanatory variables. We find that providers located in Europe sell offsets at prices that are approximately 30 percent higher than providers located in either North America or Australasia. Contrary to what one might expect, offset prices are generally higher, by roughly 20 percent, when projects are located in developing or least-developed nations. But this result does not hold for forestry-based projects. We find evidence that forestry-based offsets sell at lower prices, and the result is particularly strong when projects are located in developing or least-developed nations. Offsets that are certified under the Clean Development Mechanism or the Gold Standard, and therefore qualify for emission reductions under the Kyoto Protocol, sell at a premium of more than 30 percent; however, third-party certification from the Voluntary Carbon Standard, one of the largest certifiers, is associated with a price discount. Variables that have no effect on offset prices are the number of projects that a provider manages and a provider’s status as for-profit or not-for-profit.

Private Provision of Environmental Public Goods: Household Participation in Green-Electricity Programs

Green-electricity programs provide an opportunity to study private provision of public goods in a field setting. The first part of this paper develops a theoretical framework to analyze household decisions about voluntary participation in green-electricity programs. We consider different participation mechanisms and show how they relate to existing theory on either pure or impure public goods. The models are used to examine the implications of participation mechanisms for the level of public-good provision. The second part of the paper provides an empirical investigation of actual participation decisions in two green- electricity programs: one based on a pure public good and the other based on an impure public good. The data come from original household surveys of participants and nonparticipants in both programs, along with utility data on household electricity consumption. The econometric results are interpreted in the context of the theoretical models and are compared to other studies of privately provided public goods.Pure and impure public goods, private provision, green electricity

Explaining The Appearance and Success of Voter Referenda For Open-Space Conservation

This paper provides an empirical investigation of the factors that in?uence the appearance and success of voter referenda for policies designed to promote open-space conservation. We take advantage of a data set that includes detailed information on all such referenda that occurred in the United States between 1998 and 2003. Combining these data with information from the U.S. Census, we conduct a nationwide analysis along with focused analyses of referenda that occurred in New Jersey and Massachusetts. Among the questions that we consider are the following: What factors contribute to the appearance of an open- space referendum in a jurisdiction? How does an initiative's funding mechanism, such as a bond, property tax, sales tax, or income tax, affect the way citizens vote? How responsive are favorable votes to the costs of an open-space initiative? And how do socioeconomic characteristics affect demand for public provision of open space?

Climate Policy and Voluntary Initiatives: An Evaluation of the Connecticut Clean Energy Communities Program

Can simple government programs effectively promote voluntary initiatives to reduce greenhouse-gas emissions? This paper provides an evaluation of how the Connecticut Clean Energy Communities program affects household decisions to voluntarily purchase “green” electricity, which is electricity generated from renewable sources of energy. The results suggest that, within participating communities, subsidizing municipal solar panels as matching grants for reaching green-electricity enrollment targets increases the number of household purchases by 35 percent. The Clean Energy Communities program thus demonstrates how mostly symbolic incentives can mobilize voluntary initiatives within communities and promote demand for renewable energy.
