A Comparison of Actual and Hypothetical Willingness to Pay of Parents and Non-Parents for Protecting Infant Health: The Case of Nitrates in Drinking Water AgEcon
Loomis, John B.; Bell, Paul; Cooney, Helen; Asmus, Cheryl.
We estimate adults’ willingness to pay (WTP) to reduce health risks to their own or other families’ infants to test for altruism. A conjoint analysis of adults paying for bottled water found marginal WTP for reduction in risk of shock, brain damage, and mortality in the cash treatment of $2, $3.70, and $9.43, respectively. In the hypothetical market these amounts were $14, $26, and $66, indicating substantial hypothetical bias, although not unexpected due to the topic of infant health. Statistical tests confirm a high degree of altruism in our WTP results, and altruism held even when real money was involved.

A Review of the Literature on Telecommuting and Its Implications for Vehicle Travel and Emissions AgEcon
Walls, Margaret; Safirova, Elena.
In this paper, we review 20 relatively recent empirical studies of telecommuting, all of which focus on the trip reduction perspective. The studies include earlier ones with smaller datasets, such as some pilot studies of individual employers, and more recent studies based on broader surveys of both telecommuters and nontelecommuters. We focus on the results of the studies with respect to participation and frequency of telecommuting, the effects on vehicle-miles-traveled (VMT) and trips, and in some cases, the impacts on emissions and air quality. Although there does not seem to be a consensus, there is a predominant view that certain factors increase both the likelihood of telecommuting and the frequency of telecommuting. These factors are having children...

A Spatiotemporal Fixed Effects Estimation of U.S. State-Level Carbon Dioxide Emissions AgEcon
Burnett, J. Wesley; Bergstrom, John C..
One of the major shortcommings of past environmental Kuznets curve (EKC) studies is that the spatiotemporal aspects within the data have largely been ignored. By ignoring the spatial aspect of pollution emissions past estimates of the EKC implicitly assume that a region’s emissions are unaffected by events in neighboring regions (i.e., assume there are no transboundary pollution emissions between neighbors). By ignoring the spatial aspects within the data several past estimates of the EKC could have generated biased or inconsistent regression results. By ignoring the temporal aspect within the data several past estimates of the EKC could have generated spurious regression results or misspecified t and F statistics. To address this potential...

Adoption of Clean Leather-Tanning Technologies in Mexico AgEcon
Blackman, Allen.
In many developing countries, a host of financial, institutional, and political factors hamstring conventional environmental regulation. Given these constraints, a promising strategy for controlling pollution is to promote the voluntary adoption of clean technologies. Although this strategy has received considerable attention in policy circles, empirical research on the adoption of clean technologies in developing countries is limited. This paper presents historical background and original survey data on the adoption of five clean tanning technologies by a sample of 137 leather tanneries in Leon, Guanajuato, Mexico, a city where tanneries have serious environmental impacts and conventional environmental regulation has repeatedly failed to mitigate the...

Agricultural land management strategies to reduce phosphorus loads in the Gippsland Lakes, Australia AgEcon
Roberts, Anna M.; Pannell, David J.; Doole, Graeme J.; Vigiak, Olga.
A target to reduce phosphorus flows into the Gippsland Lakes in south-eastern Australia by 40 per cent to improve water quality has previously been established by stakeholders. An integrated analysis at the catchment scale is undertaken to assess the agricultural land management changes required to achieve this target, and to evaluate the cost-effectiveness of these changes. It appears technically feasible to achieve a 40 per cent reduction in P load entering the lakes, but the least-costly way of doing so would require around A$1 billion over 20 years, a dramatic increase in the current levels of funding provided for management. On the other hand, a 20 per cent P reduction could be achieved at much lower cost: around $80 million over 20 years and...

Air Emissions of Ammonia and Methane from Livestock Operations: Valuation and Policy Options AgEcon
Shih, Jhih-Shyang; Burtraw, Dallas; Palmer, Karen L.; Siikamaki, Juha.
The animal husbandry industry is a major emitter of methane, which is an important greenhouse gas. The industry is also a major emitter of ammonia, which is a precursor of fine particulate matter, arguably the number-one environment-related public health threat facing the nation. We present an integrated process model of the engineering economics of technologies to reduce methane and ammonia emissions at dairy operations in California. Three policy options are explored: greenhouse gas offset credits for methane control, particulate matter offset credits for ammonia control, and expanded net metering policies to provide revenue for the sale of electricity generated from captured methane gas. Individually, any of these policies appears to be sufficient to...

An Experimental Economic Analysis of Carbon Trading Options for Australia AgEcon
Tisdell, John G.; Grainger, Corinne.
Australia is currently developing a carbon emissions trading program. The Garnaut report recommendations include options for the allocation of carbon credits, trading schemes, banking and borrowing, and self reporting mechanisms. This paper reports the results of a series of economic experiments in which we explored spot and future markets given high and low levels of carbon credit reductions. The results provide important insights to the current debate in Australia and highlight the importance of well crafted market design.

An Interpretative Model of Aquaculture Multifunctionality: A Methodological Framework Definition AgEcon
De Blasi, Giuseppe; Acciani, Claudio; De Boni, A.; Roma, R..
International trade agreements and the new EU CAP targets require the definition of a new type of subsidy, depending on the non-market functions provided by production activities. The aim of the research project reported in this paper is to find a model to reward multifunctionality of aquaculture, defining all the positive externalities it involves and trying to calculate a monetary value for each of these.

Análisis del impacto medioambiental derivado de las actividades económicas. Aplicación a una economía regional AgEcon
Flores, Monica; Mainar, Alfredo J..
The goal of this paper is to analyse the households’ environmental impact in a regional economy, including the household direct impact as well as the impact associated with the production of goods and services of the household demand. Moreover, per capita ecological impacts for each household category according to income level are obtained. We focus on water consumption, and water and atmospheric pollution. The framework is based on a regional SAMEA (Social Accounting Matrix and Environmental Accounts), and vertically integrated environmental indicators using the Leontief model. An application is carried out for the Aragon case.

Assessing China’s Energy Conservation and Carbon Intensity: How Will the Future Differ from the Past? AgEcon
Zhang, ZhongXiang.
As an important step towards building a “harmonious society” through “scientific development”, China has incorporated for the first time in its five-year economic plan an energy input indicator as a constraint. While it achieved a quadrupling of its GDP while cutting its energy intensity by about three quarters between 1980 and 2000, China has had limited success in achieving its own 20% energy-saving goal set for 2010 to date. Despite this great challenge at home, just prior to the Copenhagen climate summit, China pledged to cut its carbon intensity by 40-45% by 2020 relative its 2005 levels to help to reach an international climate change agreement at Copenhagen or beyond. This raises the issue of whether such a pledge is ambitious or just represents...

Assessing the Market for Poultry Litter in Georgia: Are Subsidies Needed to Protect Water Quality? AgEcon
Mullen, Jeffrey D.; Bekchanov, Ulugbek; Karali, Berna; Kissel, David; Risse, Mark L.; Rowles, Kristin; Collier, Sam.
Concerns about nutrient loads into our waters have focused attention on poultry litter applications. Like many states with a large poultry industry, Georgia recently designed a subsidy program to facilitate the transportation of poultry litter out of vulnerable watersheds. This paper uses a transportation model to examine the necessity of a poultry litter subsidy to achieve water protection goals in Georgia. We also demonstrate the relationship between diesel and synthetic fertilizer prices and the value of poultry litter. Results suggest that a well functioning market would be able to remove excess litter from vulnerable watersheds in the absence of a subsidy.

Assessing the Risk of Oil Spills in the Mediterranean: the Case of the Route from the Black Sea to Italy AgEcon
Bigano, Andrea; Sheehan, Paul.
Recent major spills on European coasts have highlighted the primary policy relevance for the EU of oil spills. This paper assesses the risks related to carrying oil to the EU along the route from the Russian Black Sea coast to Sicily, Italy (one of the most congested and strategically relevant European import routes). We develop a methodology based on Fault Tree Analysis, and we apply it to the most likely causes of an oil spill. We couple the resulting probabilities with data on expected spill size, types of oil carried and cleanup costs, to estimate expected costs for cleanup and loss of cargo. The route analysed appears to be a risky one; there is a “high” to “very high” risk of a spill along this route. The Turkish Straits turn out to be the major...

Atmospheric Pollution and Consumption Patterns in Spain: An Input-Output Approach AgEcon
Serrano, Monica; Roca, Jordi.
This paper analyses the relationship between Spanish household consumption patterns and atmospheric pollutant emissions in 2000. Applying an input-output approach we estimate the relative responsibility of different types of households in the emissions of nine different atmospheric pollutants: the six greenhouse gases (CO2, CH4, N2O, SF6, HFCs and PFCs) regulated by the Kyoto protocol and three other gases (SO2, NOx and NH3). We combine input-output tables, national consumer survey statistics and environmental pollution satellite accounts into an environmental extended input-output model. We also analyse the assumptions required in order to apply the model to available data. We find that there is a positive and very high relationship between the level of...

Breaking the Impasse in International Climate Negotiations: A New Direction for Currently Flawed Negotiations and a Roadmap for China to 2050 AgEcon
Zhang, ZhongXiang.
China’s unilateral pledge to cut its carbon intensity by 40-45 percent by 2020 relative to its 2005 levels raises both the stringency issue, and given that China’s pledge is in the form of carbon intensity, reliability issues concerning China’s statistics on energy and GDP. Moreover, as long as China’s commitments differ in form from those of other major greenhouse gas emitters, China is constantly confronted with both criticism on its carbon intensity commitment being less stringent and the threats of trade measures. In response to these concerns and to put China in a positive position, this paper will map out a realistic roadmap for China’s specific climate commitments towards 2050, with its main distinguishing features including China taking on absolute...

Carbon Kuznets Curves: Long-run Structural Dynamics and Policy Events AgEcon
Mazzanti, Massimiliano; Musolesi, Antonio.
We study the structural differences among climate change leading ‘factors’ - Northern EU members -, and lagging actors - southern EU countries and the ‘Umbrella group’ - with regard to long run carbon-income relationships. Homogeneous and heterogeneous panel models show that the groups of countries less in favour of stringent climate policy have yet to experience a Kuznets curve, though they show relative delinking. Northern EU instead robustly shows bell shapes. Exogenous policy events such as the 1992 climate change convention appear to be relevant in shaping the EKC of Northern EU. In addition, other events such as the second oil price shock appear to have also impacted in shaping the long run emission/GDP dynamics.

Carbon Labeling for Consumer Food Goods AgEcon
Shewmake, Sharon; Okrent, Abigail M.; Thabrew, Lanka; Vandenbergh, Michael.
We construct a model to predict how consumers will respond to better information about the carbon content of 42 foods and a nonfood composite as well as product categories through a label, and provide guidance as to what kinds of goods would provide the highest CO¬2eq emission reductions through a labeling scheme. Our model assumes that consumers value their individual carbon footprint, allowing us to utilize estimates of own- and cross-price elasticities of demand from the literature on demand analysis. We make three different assumptions about how consumers currently value their carbon footprint and find that when a label informs consumers, their baseline perception matters. We also find that carbon labels on alcohol and meat would achieve the largest...

Certification as a Rationale for Voluntary Agreements AgEcon
Gonzalez, Patrick.
I model the participation of firms in a voluntary agreement as a costly certification process whereby a firm informs the Regulator of its pollution intensity. Without this knowledge, the Regulator imposes the same tax on all firms in a heterogeneous industry, unduly hurting the clean ones with the lowest intensity. Certification allows clean firms to get a tax rebate. It also entails an informational externality as the dispersion of types decreases within the pool of non-participating firms, following an unraveling process. Because participation is a firm’s private decision, there is such a thing as a bad voluntary agreement.

Civil Liability, Safety and Nuclear Parks: Is Concentrated Management Better? AgEcon
Mondello, Gerard.
Ultra-hazardous risky activities as nuclear industry cannot be considered as “normal industries” i.e. industries without abnormal environmental and health risks. Consequently, the industrial organization of these specific sectors is of the utmost importance. This paper aims at studying this question. We focus on the associated costs of prevention and civil liability. We analyze how civil liability rules may contribute to extend or to discourage the expansion of nuclear parks to new operators. The paper compares the consequences of extending the management of nuclear stations to several independent operators. This question can apply to the unification process of the European electricity market in which several public and private nuclear power operators are...
