Última Economic valuation of the Emas waterfall, Mogi-Guaçu River, SP, Brazil Anais da ABC (AABC) Peixer,Janice; Giacomini,Henrique C.; Petrere Jr,Miguel. The Emas waterfall in Mogi-Guaçu River is regionally recognized as an important fishing spot and touristic place. The first reports of the professional and sport fishing there date back from the 30's, which is the same period when the tourism took place. The present paper provides an environmental valuation of this place and an assessment of the differences among the major groups of people using the area. During 2006 we interviewed 33 professional fishers, 107 sport fishers, 45 tourists and 103 excursionists in order to estimate the Willingness to Pay (WTP) for each category and to analyze the influence of socioeconomic factors by means of logistic regressions and ANCOVAs. The WTP of professional fisher was significantly influenced by age and education,...

Ano: 2011 URL: http://hdl.handle.net/10521/533 Consumers’ Valuation of GMO Segregation Programs in Japan AgEcon Matsumoto, Shigeru. The contingent valuation method was used to elicit Japanese consumers’ willingness-to-pay for genetically modified organism (GMO) segregation programs. The results revealed that most consumers pay nonnegligible premiums for products produced under strict GMO-segregation programs. However, we found that the premium did not vary by the threshold level of GMO content in the product. We further found that a government certification did not increase the premium for GMO-segregation programs. Therefore, an additional mandatory regulation to reduce GMO contaminations would not be worthwhile because such a regulation would incur substantial enforcement costs.

Ano: 2006 URL: http://purl.umn.edu/43760 Do CVM Welfare Estimates Suffer from On-Site Sampling Bias? A Comparison of On-Site and Household Visitor Surveys AgEcon Gonzalez-Sepulveda, Juan Marcos; Loomis, John B.. The problem of endogenous stratification associated with on-site sampling has been overlooked in the Contingent Valuation Method (CVM). We find that using on-site samples of visitors overstates visitor willingness to pay (WTP) estimates relative to a household sample of visitors, and substantially overstates the unconditional population values. We provide two methods of correcting WTP of on-site samples. The uncorrected on-site sample CVM yields WTP of $132 per trip, while visitor WTP obtained from a random sample of households had a value of $66 per trip. Adaptation of choice-based sampling correction estimator to the on-site CVM data yields $73 per trip, not statistically different from the visitor value from the household survey, but significantly...

Ano: 2010 URL: http://purl.umn.edu/95610 Social ex-post evaluation of local development programs: application of a contingent valuation approach to the Guadix-Marquesado LEADER area (Spain) AgEcon Calatrava-Requena, Javier; Gonzalez-Roa, Maria del Carmen. As part of the evaluation of the activity of a district’s local development group (LAG), valuation by local society could be a potential element of interest. In this paper we present a social valuation of the LAG activity in the Guadix-Marquesado district (south-eastern Spain), where the contingent valuation method is one of the analytical elements used. A number of results show how the LAG has now become part the institutional network closest to local society, which values the increased welfare that its activity generates slightly more than its actual annual operating expenses. This somehow socially legitimizes the public funding it receives. Other results pertaining to change perception, familiarity with LAG activities and the scalar valuation of its...

Ano: 2011 URL: http://purl.umn.edu/100041 A Comparison of Methodologies for Valuing Decreased Health Effects from Wildfire Smoke AgEcon Richardson, Leslie; Loomis, John B.; Champ, Patricia A.. Wildfire seasons are becoming longer and more intense throughout the world, making it increasingly important to monetize the full damages caused by wildfires when analyzing various fire management policies. We estimate the economic costs of the health effects associated with exposure to wildfire smoke using a simple cost of illness approach and for the first time to our knowledge we estimate willingness-to-pay (WTP) for a decrease in symptom days from wildfire smoke using the contingent valuation method and the averting behavior method. Comparing estimates across all three common approaches for estimating the economic cost of exposure to an air pollutant is an important contribution to the literature. This study uses data from the largest wildfire in Los...

Ano: 2010 URL: http://purl.umn.edu/61252 Consumer Willingness to Pay for Swiss Chicken Meat: An In-store Survey to Link Stated and Revealed Buying Behaviour AgEcon Bolliger, Conradin; Reviron, Sophie. In a global economy food origin is gaining increasing attention as determining purchase criterion in food consumption. Consequently, for many consumers a product’s country-of-origin (COO) is an important cue in evaluating both domestic and foreign products. A double-bounded dichotomous choice approach in an in-store setting was used to assess consumers’ preference and willingness-to-pay (WTP) for the product attribute “Swiss origin” relative to “European origin” for chicken meat. Data collection took place in the poultry section of six grocery stores in Francophone Switzerland. Sample selection was based on the consumer’s purchase decision, that is only actual chicken buyers were questioned. During the survey product data of participants’ actual purchase...

This research is aimed at investigating the consumer’s preference for food produced in Taiwan and the economic benefits for the country of origin labeling. The study uses both experimental auction and contingent valuation method (CVM) to investigate factors that affect the consumer’s willingness to pay (WTP) for products under country-of-origin labeling (COOL). Experimental auctions of Taiwan and China preserved olives as well as Taiwan, China and Vietnam oolong teas were conducted using the Vickrey’s second price sealed bid auction. For CVM, the study used the double-bounded dichotomous choice method in which we started assuming the same base price for all products in the first question and then varied the prices in the second CV question. The products...

Ano: 2009 URL: http://purl.umn.edu/49215 ECONOMIC VALUATION OF SOME WETLAND OUTPUTS OF MUD LAKE, MINNESOTA-SOUTH DAKOTA AgEcon Roberts, Lisa A.; Leitch, Jay A.. The objective of this study was to estimate some economic values of Mud Lake, a managed, lacustrine wetland on the Minnesota-South Dakota border. Several outputs of Mud Lake were identified and an economic value was estimated for each. Flood control was valued at approximately $440 per acre, based on dollar damages prevented; water supply, using public utility revenues, was valued at $94 per acre; fish/wildlife habitat, recreation, and aesthetics were valued at about $21 per acre using the Contingent Valuation Method; and corrective expenditures were used to evaluate water quality at a negative per acre value of $180. When capitalized at 6 percent, the estimated total annual value of these four outputs is $6,250 per acre. These values can assist...

Ano: 1997 URL: http://purl.umn.edu/23406 Consumers' Willingness to Pay for Biotech Foods in China AgEcon Lin, William W.; Somwaru, Agapi; Tuan, Francis C.; Huang, Jikun; Bai, Junfei. Based on a large-scale consumer survey, this study employs a semi-double-bounded dichotomous choice model to estimate the mean willingness to pay (WTP) for biotech foods in China. The study also accounts for the effects of respondents' characteristics on the probability of purchasing biotech foods and WTP. Analyses focus on biotech soybean oil and insect-resistant biotech rice.

Ano: 2005 URL: http://purl.umn.edu/19569 Estimating values for recreational fishing at freshwater dams in Queensland AgEcon Rolfe, John; Prayaga, Prabha. In this paper, estimates of value for recreational fishing are reported for three major freshwater impoundments in Queensland, Australia, using both travel cost and contingent valuation methods. Policy analysts often require estimates of value when analysing the importance of recreation against other uses of impoundments, or when considering the potential for further investments, such as with fish stocking programs. Different forms of the travel cost method are used to estimate separate consumer surpluses associated with two key subgroups of recreational anglers: frequent and occasional anglers. A contingent valuation study is used to estimate the marginal values associated with a potential improvement in fishing experience. The results of the travel cost...

Ano: 2007 URL: http://purl.umn.edu/118325 Environmental value and valuation over time AgEcon Scheufele, Gabriela; Bennett, Jeffrey W.. Time and value are related concepts that influence human behaviour. Although classical topics in human thinking throughout the ages, few environmental economic non-market valuation studies have attempted to link the two concepts. Economists have estimated non-market environmental values in monetary terms for over 30 years. This history of valuation provides an opportunity to compare value estimates and how valuation techniques have changed over time. This research aims to compare value estimates of benefits of a protected natural area. In 1978, Nadgee Nature Reserve on the far south coast of New South Wales was the focus of the first application of the contingent valuation method in Australia. This research aims to replicate that study using both the...

Ano: 2008 URL: http://purl.umn.edu/94805 Verfahren zur Korrektur des Embedding-Effektes bei der Kontingenten Bewertung AgEcon Meyerhoff, Jurgen. The use of economic tools such as the benefit-cost analysis often requires determining non-market values of environmental goods. One of the appropriate measures to determine these values is the contingent valuation. As a stated preference technique it allows to measure non-use values as well as to value future states of the environment. However, the credibility of the contingent valuation is still under debate because people only state a hypothetical willingness to pay. One of the most debated elicitation effects of this method is the embedding effect. In this paper, two approaches to take account of that effect are presented. Both use follow-up questions in order to obtain self reports from respondents. Each approach was employed in one of two contingent...

Ano: 2003 URL: http://purl.umn.edu/98081 Measuring Consumer Willingness to Pay for a Health Risk Reduction of Salmonellosis and Campylobacteriosis AgEcon Goldberg, Isabell; Roosen, Jutta. This paper presents an application of the contingent valuation method (CVM) and choice experiments (CEs). We examine consumer willingness to pay (WTP) for different health risk reduction levels of Salmonellosis and Campylobacteriosis acquired from the consumption of chicken breast. We test for the embedding effect. The embedding effect was not found in the CVM format. It was however present in the CEs. The WTP values in the CVM format rages from Euro 1.29 to 3.34, whereas the WTP obtained by the CEs ranges from Euro -0.16 to Euro 6.68 depending on the disease and the corresponding risk reduction levels.
