Última A multi-level cost benefit approach for regulatory decision support in food safety and quality assurance scenarios AgEcon Fritz, Melanie; Schiefer, Gerhard. In complex policy decision situations where policy objectives can only be reached through appropriate activities of individual actors with own decision authority and individual objectives, the classical approaches for measuring the effects of regulatory initiatives through cost-benefit or related types of analysis do not provide the appropriate information for decision support. This paper discusses a framework for a multi-level analysis approach that could provide decision support in multi-level policy decision situations.

Ano: 2008 URL: http://purl.umn.edu/44274 Willingness to Pay for Mortality Risk Reductions: Does Latency Matter? AgEcon Alberini, Anna; Cropper, Maureen L.; Krupnick, Alan J.; Simon, Nathalie B.. Using results from two contingent valuation surveys conducted in Canada and the United States, we explore the effect of a latency period on willingness to pay (WTP) for reduced mortality risk using both structural and reduced form approaches. We find that delaying the time at which the risk reduction occurs by 10 to 30 years significantly reduces WTP for respondents aged 40 to 60 years. Additionally, we estimate implicit discount rates equal to 8% for Canada and 4.5% for the United States-both well within the range established previously in the literature.

Ano: 2004 URL: http://purl.umn.edu/10500 Current Contribution of Four Biotechnologies to New Zealand's Primary Sector AgEcon Kaye-Blake, William; Saunders, Caroline M.; Emanuelsson, Martin. Over the last several decades, changes to production technologies have significantly increased output from the primary sector. The contribution of improved genetics has been variously estimated, and the impacts of genetic engineering have received much attention. The present research estimated the economic impact of four modern biotechnologies (other than genetic engineering) on the primary sector. Information from interviews with key informants was incorporated into a cost-benefit analysis to estimate these impacts. The net contribution was estimated at $266 million per year, with impacts spread unevenly through the sector and across biotechnologies.

Ano: 2006 URL: http://purl.umn.edu/25411 Efficient Emission Fees in the U.S. Electricity Sector AgEcon Banzhaf, H. Spencer; Burtraw, Dallas; Palmer, Karen L.. This paper provides new estimates of efficient emission fees for sulfur dioxide (SO2) and nitrogen oxides (NOX) emissions in the U.S. electricity sector. The estimates are obtained by coupling a detailed simulation model of the U.S. electricity markets with an integrated assessment model that links changes in emissions with atmospheric transport, environmental endpoints, and valuation of impacts. Efficient fees are found by comparing incremental benefits with emission fee levels. National quantity caps that are equivalent to these fees also are computed, and found to approximate caps under consideration in the current multi-pollutant debate in the U.S. Congress and the recent proposals from the Bush administration for the electricity industry. We also...

Ano: 2002 URL: http://purl.umn.edu/10505 (In)Efficient Management of Interacting Environmental Bads AgEcon Kuosmanen, Timo; Laukkanen, Marita. Many environmental problems involve the transformation of multiple harmful substances into one or more damage agents much in the same way as a firm transforms inputs into outputs. Yet environmental management differs from a firm’s production in one important respect: while a firm seeks efficient input allocation to maximize profit, an environmental planner allocates abatement efforts to render the production of damage agents as inefficient as possible. We characterize a solution to the hmultiple pollutants problem and show that the optimal policy is often a corner solution, in which abatement is focused on a single pollutant. Corner solutions may arise even in well-behaved problems with concave production functions and convex damage and cost functions....

Ano: 2009 URL: http://purl.umn.edu/54287 Can genetic engineering for the poor pay off? An ex-ante evaluation of Golden Rice in India AgEcon Stein, Alexander J.; Sachdev, H.P.S.; Qaim, Matin. Genetic engineering (GE) in agriculture is a controversial topic in science and society at large. While some oppose genetically modified crops as proxy of an agricultural system they consider unsustainable and inequitable, the question remains whether GE can benefit the poor within the existing system and what needs to be done to deliver these benefits? Golden Rice has been genetically engineered to produce provitamin A. The technology is still in the testing phase, but, once released, it is expected to address one consequence of poverty " vitamin A deficiency (VAD) " and its health implications. Current interventions to combat VAD rely mainly on pharmaceutical supplementation, which is costly in the long run and only partially successful. We develop a...

Ano: 2006 URL: http://purl.umn.edu/8534 Costs and Benefits of a WTO Dispute: Philippine Bananas and the Australian Market AgEcon Javelosa, Josyline C.; Schmitz, Andrew. Why do governments engage in WTO disputes? What can countries expect to gain from international legal trade battles? This article examines the costs and benefits of the Philippine-Australian dispute regarding Australia's quarantine policy on Philippine fresh fruits and vegetables, a case also of keen interest to a number of countries including those in the European Union, the United States, Canada, Ecuador, Thailand, China, India, and Chile. We find that a host of institutional, political, and economic factors can trigger disputes under strong, yet debatable, expectations over winning a case in the WTO.

Ano: 2006 URL: http://purl.umn.edu/23824 Industry-mandated testing to improve food safety: the new US marketing order for pistachios AgEcon Brunke, Henrich; Alston, Julian M.; Gray, Richard S.; Sumner, Daniel A.. Food safety shocks can threaten the health of consumers, create havoc within an industry and result in severe losses to producers. Governments often attempt to aid food safety by mandating standards and inspection of food products to supplement the efforts by private firms and industries. This article assesses a form of collective action that falls between typical government mandates and purely private action. The California pistachio industry recently established a U.S. federal marketing order, which sets quality standards and inspection to reduce the likelihood of dangerous or poor quality pistachios. Simulation results indicate that, across the full range of parameters used in the analysis, the benefit-cost analysis was always favorable to the new...

Ano: 2004 URL: http://purl.umn.edu/97502 The Evolution of NOx Control Policy for Coal-Fired Power Plants in the United States AgEcon Burtraw, Dallas; Evans, David A.. Emissions of nitrogen oxides (NOx ) contribute to formation of particulate matter and ozone, and also to acidification of the environment. The electricity sector is responsible for about 20% of NOx emissions in the United States, and the sector has been the target of both prescriptive (command-and-control) and flexible (cap-and-trade) approaches to regulation. We summarize the major NOx control policies affecting this sector, and provide some perspectives as to their effectiveness. While both prescriptive and flexible approaches continue to play an important role, significant new proposals have wholly embraced a cap-and-trade approach.

Ano: 2003 URL: http://purl.umn.edu/10645 Cost-Benefit Analysis of a WTO Dispute AgEcon Javelosa, Josyline C.; Schmitz, Andrew. Since the WTO's inception in 1995, the number of cases it has dealt with has exceeded the number of disputes under the GATT. This suggests that Members have found the WTO dispute settlement system a useful means to pursue their interests. In this paper, we analyze an ongoing WTO dispute to illustrate the economic and political costs and benefits that accrue to parties when they engage themselves into the formal dispute process. We draw on the Philippine-Australian case, which challenges the latter's quarantine policy on fresh fruit and vegetables, to understand further how the WTO dispute settlement system affects state behavior and litigation patterns. This particular case is also of keen interest to a number of countries, including the EC, US, Canada,...

Ano: 2004 URL: http://purl.umn.edu/15648 COST-BENEFIT ANALYSIS OF THE DUTCH NATURE CONSERVATION POLICY: DIRECT, INDIRECT EFFECTS AND TRANSACTION COSTS OF THE ECOLOGICAL MAIN STRUCTURE IN THE NETHERLANDS AgEcon Jongeneel, Roelof A.; Polman, Nico B.P.; Slangen, Louis H.G.. The scattering of nature areas in the Netherlands and the increased demand for nature lead to a governmental project in 1990 to complete a network of nature favouring areas, the ecological main structure, in 2018. The financial and economic costs and benefits of this project were analysed. Targets for purchasing of agricultural land and conversion into nature were adjusted several times as the land price doubled between 1995 and 2000. The purchasing rate still has to double, which will probably drive up the land price even further. The alternative is long-term contracts with farmers or private landowners for nature conservation.

This paper analyses costs and benefits of planting trees on marginal lands across forestry zones in Ukraine with the purpose of using them for timber production, erosion prevention and climate change mitigation. The research reveals that establishment of new forests to increase timber production and alleviate soil erosion is economically and environmentally justified in some regions. Incorporating the effects of afforestation through on climate change mitigation increases social benefits.

Ano: 2009 URL: http://purl.umn.edu/51814 An Integrated Assessment approach to linking biophysical modelling and economic valuation tools AgEcon Kragt, Marit Ellen; Bennett, Jeffrey W.; Jakeman, Tony. Natural resource management (NRM) typically involves complex decisions that affect a variety of stakeholder values. Efficient NRM, which achieves the greatest net environmental, social and financial benefits, needs to integrate the assessment of environmental impacts with the costs and benefits of investment. Integrated assessment (IA) is one approach that incorporates the several dimensions of catchment NRM, by considering multiple issues and knowledge from various disciplines and stakeholders. Despite the need for IA, there are few studies that integrate biophysical modelling tools with economic valuation. In this paper, we demonstrate how economic non-market valuation tools can be used to support an IA of catchment NRM changes. We develop a Bayesian...

Ano: 2010 URL: http://purl.umn.edu/94949 Valuing Externalities of Watershed Restoration and Erosion Control Projects in Mediterranean Basins: A Comparative Analysis of the Contingent Valuation and Replacement Cost Methods AgEcon Saez, Maria Del Carmen Almansa; Calatrava-Requena, Javier. The methodology used for Economic Valuation of the Externalities generated by the Watershead Restoration and Erosion Control Projects in the Hydrographic Basins of the Mediterranean Slope, is based on the Replacement Cost Method. Environmental Economics, however, today offer us other methodological possibilities, whose application to the valuation of this type of project may prove to be of interest. It is the case of the Contingent Valuation Method used for the evaluation of the effects of the Watershead Restoration and Erosion Control Projects of the Aljibe Basin (Almería) Spain, presented here. The results obtained show that, in this case study, application of Contingent Valuation ascribes greater social profitability of the project, with 5.23 % of IRR...

Ano: 2002 URL: http://purl.umn.edu/24847 Economic Benefits and Costs of Jatropha Plantation in North-East India AgEcon Goswami, Kishor; Saikia, Jitu; Choudhury, Hari Kanta. Energy security, emissions control and environmental concerns are some of the issues that drive India to search for bio-fuels in general and bio-diesel in particular as an alternative source of energy. The inception of National Biofuel Mission in 2003 has resulted in expansion of jatropha plantations in different states of the country. In North-East India, jatropha plantation was started in 2007, mostly at small farmers’ level with direct and indirect initiatives of the government and the private sector. However, adoption and expansion of jatropha plantation in the rural areas largely depend on profitability from such plantations at farmers’ level. The present study has assessed the profitability of jatropha plantation in four states of North-East India,...

Ano: 2011 URL: http://purl.umn.edu/109423 Expanding the Focus of Cost-Benefit Analysis for Food Safety: A Multi-Factorial Risk Prioritization Approach AgEcon Caswell, Julie A.. A pressing need in the area of food safety is a tool for making overall, macro judgments about which risks should be given priority for management. Governments often seek to base this prioritization on public health impacts only to find that other considerations also influence the prioritization process. A multi-factorial approach formally recognizes that public health, market-level impacts, consumer risk preferences and acceptance, and the social sensitivity of particular risks all play a role in prioritization. It also provides decision makers with a variety of information outputs that allow risk prioritization to be considered along different dimensions. Macro-level prioritization of risks based on multiple factors is an important expanded use of...

Ano: 2008 URL: http://purl.umn.edu/42131 Valuing the non-market production of agriculture AgEcon Ahlheim, Michael; Fror, Oliver. As a consequence of the negotiations for a new agricultural policy of the EU the multifunctionality of agricultural production has come into new prominence in the public. The philosophy that subsidies for the agricultural sector should be calculated not only by agricultural market production but also according to agricultural noncommodity production like e.g. the conservation of the countryside, makes it necessary to assess the social value of this part of agricultural production. In this paper we scrutinize the welfare theoretical background of the economic valuation of non-market production as well as the existing practical valuation techniques. Further, the applicability of these techniques to the valuation of agricultural noncommodity production is...

Managing the growing quantity of used electronic equipment poses challenges for waste management officials. In this paper, we focus on a large component of the electronic waste stream— computer monitors-and the disposal concerns associated with the lead embodied in cathode ray tubes (CRTs) used in most monitors. We develop a policy simulation model of consumers- disposal options based on the costs of these options and their associated environmental impacts. For the stock of monitors disposed of in the United States in 1998, our preliminary findings suggest that bans on some disposal options would increase disposal costs from about $1 per monitor to between $3 and $20 per monitor. Policies to promote a modest amount of recycling of monitor parts, including...

Ano: 2001 URL: http://purl.umn.edu/10901 Revegetation of Regent Honeyeater habitat in the Capertee Valley: a Cost-Benefit Analysis AgEcon Greyling, Tertius; Bennett, Jeffrey W.. This study considers the costs and benefit of the Regent Honeyeater Project in the Capertee Valley over the past 10 years. The benefits are estimated using choice modelling and the costs are based on project expenditure and forgone agricultural production. A comparison of the benefits and costs yields a benefit-cost ratio (BCR) of 4.45, which implies that the benefits outweigh the costs. However, variation in the underlying assumptions reveal significant sensitivity to the uncertainty associated with the maturation of native tree plantings and the successful establishment of a significant population of birds within the native vegetation. The Cost Benefit Analysis (CBA) is dominated by the benefit derived from protection of the native species (i.e. the...
