This paper develops a framework for assessing the potential economic impact of a regional promotion campaign combining contingent valuation methods with a partial displacement equilibrium model. The proposed approach is applied to the evaluation of the potential economic impact of the locally grown campaign in South Carolina. Results reveal that the first season of the promotion campaign increased consumer willingness to pay for produce by 3.4%. The change in consumer preferences and the corresponding shift in demand increased producer surplus by $3.09 million. This economic benefit, combined with the 2007 promotion campaign investment, resulted in a benefit-cost ratio of 6.18.

Willingness to Pay for Biodiesel in Diesel Engines: A Stochastic Double Bounded Contingent Valuation Survey

Jeanty, Pierre Wilner; Haab, Timothy C.; Hitzhusen, Frederick J..

The double bounded dichotomous choice format has been proven to improve efficiency in contingent valuation models. However, this format has been criticized due to lack of behavioral and statistical consistencies between the first and the second responses. In this study a split sampling methodology was used to determine whether allowing respondents to express uncertainty in the follow-up question would alleviate such inconsistencies. Results indicate that allowing respondents to express uncertainty in the follow-up question was effective at reducing both types of inconsistencies while efficiency gain is maintained.

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...

The economy of Dominica faces a unique set of challenges. As with many other Caribbean nations, Dominica has historically been dependent upon agriculture. Over the past several hundred years, the island's economy has been largely supported through the concentrated mono-cropping of a variety of export-oriented crops including coffee, limes, vanilla, and bananas (FAVACA, 2008). Today, approximately 45% of Dominica's labor force is employed in the agricultural sector (FAVACA, 2008). While neighboring countries have economically benefited from tourism, due to its lack of white sand beaches, Dominica is not a typical tourist destination. Taking advantage of its landscape, rainforests, and diversity of natural wildlife, in an effort to diversify its economy...

In this paper we present the results of a contingent valuation study and an experimental approach to estimating the willingness to pay for fresh milk produced in the consumer's own region. In contrast to the fictitious contingent valuation study, responses in the experimental investigation are connected with real demand decisions and real financial payoffs in an incentive-compatible way. The experimental setup allows to quantify the bias in stated willingness to pay that results from the contingent valuation’s hypothetical character. In essence, the data suggest that there exists a considerable demand for milk from the consumers` home region. Yet, significantly less demand is found in the experimental investigation. At the same time, subjects accept...

Ambivalent statements in contingent valuation studies: inclusive response formats and giving respondents time to think

Consumer Preferences for Locally Made Specialty Food Products Across Northern New England

Svedsater, Henrik.

A recent concern in the valuation literature is the uncertainty respondents feel when posed with willingness-to-pay questions for environmental amenities in hypothetical market scenarios. Using a multiple-bounded discrete-choice format, the results indicate that respondents become less ambivalent when allowed considerable time to think about the valuation task before a response is elicited. In particular they tend to reduce the reported willingness to pay associated with low certainty of paying, hence resulting in more conservative welfare estimates. Implications for the application of environmental valuation techniques are discussed.

Giraud, Kelly L.; Bond, Craig A.; Bond, Jennifer Keeling.

Does willingness to pay a premium for local specialty food products differ between consumers in Maine, New Hampshire, and Vermont? Two food categories are investigated: low-end ($5) and high-end ($20) products. Premia estimates are compared across states and across base prices within states using dichotomous choice contingent valuation methods. Results suggest that the three states of northern New England have many similarities, including comparable price premia for the lower-priced good. However, there is some evidence that the premium for the higher-priced good is greater for the pooled Vermont and Maine treatment than for the New Hampshire treatment. Vermont and New Hampshire residents are willing to pay a higher premium for a $20 than for a $5 food...

Land Use Issues: The Last Settler’s Syndrome

Valuing the non-market production of agriculture

Groothuis, Peter A..

In the last settler’s syndrome, each new settler wants the area to remain as it was on their arrival. Newcomers’ preferences often differ from long-term residents, and conflicts arise. To explore land use issues among various groups, a survey of opinions on mountain views was developed and administered to Watauga County residents in western North Carolina. Watauga County provides an interesting case study, because it is a growing area with an influx of newcomers along with long-time residents. The results suggest that agreements can be achieved on some land use issues, whereas disagreements will arise on others.

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...

Willingness to Pay for Conservation of the Asian Elephant in Sri Lanka: A Contingent Valuation Study

Bandara, Ranjith; Tisdell, Clement A..

Results from a CVM survey of willingness to pay for the conservation of the Asian elephant of a sample of urban residents in three selected housing schemes in Colombo, the capital of Sri Lanka, are reported. Face– to–face surveys were conducted using an interview schedule. A non-linear logit regression model was constructed to analyse the respondents’ responses for the payment principle questions and to identify the factors that influence their responses. We investigate whether urban residents’ WTP for the conservation of elephants is sufficient to compensate farmers for the damage caused by elephants, and consequently to raise farmers’ tolerance of the presence of elephants on the farming fields. We find that beneficiaries (the urban residents) could...

Reports experimental results involving 204 members of the public who were asked their willingness to pay for the conservation of the mahogany glider Petaurus gracilis on three occasions: prior to information being provided to them about the glider and other wildlife species; after such information was provided, and after participants had an opportunity to see live specimens of this endangered species. Variations in the mean willingness to pay are analysed. Concerns arise about whether information provision and experience reveal ‘true’ contingent valuations of public goods and about the choice of the relevant contingent valuation measure.

Virtually all technology adoption studies are conducted ex post, yet policy makers often need to assess the likely level of adoption before the technology is introduced. This study uses data from a contingent valuation survey of Michigan corn growers to assess what factors would influence the adoption of two safer corn herbicides, one that is not carcinogenic and one that does not leach. Results indicate that price, risk perception, and sources of pest control information are all important. This suggests that public policies designed to change perceptions and improve information dissemination may encourage voluntary use of more environmentally friendly technologies.

This paper reports results from a U.S. national telephone survey on genetically modified foods (vegetable oil, cornflakes, and salmon). The survey featured a contingent valuation in which respondents chose between the GM and non-GM alternatives with an option of indifference. The binomial and multinomial logit models yielded estimated willingness to pay (WTP) to avoid the GM alternatives. Respondents were willing to pay 20.9%, 14.8%, 28.4%, and 29.7% of the base prices to avoid GM vegetable oil, GM cornflakes, GM-fed salmon, and GM salmon, respectively. The inclusion of indifference option could increase the sample size and moderate the mean WTP.

Willingness to pay for different degrees of Abundance of Elephants

Bandara, Ranjith; Tisdell, Clement A..

This paper presents an application of the contingent valuation method (CVM) to determine how the willingness to pay (WTP) for conservation of Asian elephants varies with hypothetical variations in their population. Results from a CVM survey of a sample of urban residents in Colombo, the capital of Sri Lanka are used for this purpose. We find, consistent with the basic principles of consumer demand theory, the marginal change in the respondents’ WTP amounts is positive but appears to diminish in parallel to the increases in the current wild elephant population (CWEP). In contrast to theoretical expectations, however, we find that the WTP for preserving this species increases at an increasing rate in relation to decreases in the CWEP. This is probably...

This paper explores the way in which the stated willingness to pay for the conservation of Asian elephants in Sri Lanka varies with hypothetical variations in their abundance. To do that, it relies on results from a sample of residents of Colombo. The willingness to pay function is found to be unusual. It increases at an increasing rate for hypothetical reductions in the elephant population compared to its current level (a level that makes the Asian elephant endangered) and also increases at a decreasing rate for increases in this population from its current level. Rational explanations are given for this relationship. The relationship is, however, at odds with relationships suggested in some of the literature for total economic value as a function of...

This paper presents a case study on the development and implementation of a decentralised and outcome-based agri-environmental payment scheme in a project region in central Germany. A research group from Goettingen University together with local actors designed the scheme which complies with the European Union’s Common Agricultural Policy. The core of the programme is the creation of a market for ecological goods, in this case: of plant diversity standards in agriculture. Supply is provided by the local farmers, who, in an open competitive bidding, offer to produce as much as they are willing to of the commodity in question. The local population has to be seen as the beneficiary of these environmental goods. In the project, it is represented by a Regional...

Referendum Design and Contingent Valuation: The NOAA Panel's No-Vote Recommendation

Carson, Richard T.; Hanemann, W. Michael; Kopp, Raymond J.; Krosnick, Jon A.; Mitchell, Robert C.; Presser, Stanley; Ruud, Paul A.; Smith, V. Kerry; Conaway, Michael; Martin, Kerry.

In 1992 the National Oceanic and Atmospheric Administration (NOAA) convened a panel of prominent social scientists to assess the reliability of natural resource damage estimates derived from contingent valuation (CV). The product of the Panel's deliberations was a report that laid out a set of recommended guidelines for CV survey design, administration, and data analysis. One of the Panel's recommendations was that CV surveys should employ a referendum approach. This method describes a choice mechanism that asks each respondent how they would vote if faced with a particular program and the prospect of paying for the program through some means, such as higher taxes. The Panel also recommended that CV referendum questions which commonly use only "for" or...

This paper analyzes the links between agriculture and tourism. A contingent valuation study assesses tourist's willingness to pay (WTP) for agro-tourism and agriculture's positive environmental services and related positive externalities. The paper analyzes factors influencing tourist preferences in the Dominican Republic (DR) -- tourist income, the local tourist destination, sex, and nationality stand out among these factors. Estimates are given for different WTP scenarios according to farming systems. The study argues that a well developed agro-tourism industry would result in a market mechanism generating additional income of US $251 to US $364 million annually. Agro-tourist activities would have the added benefit of promoting sustainable agricultural...

THE DYNAMIC FORMATION OF WILLINGNESS TO PAY: AN EMPIRICAL SPECIFICATION AND TEST

Corrigan, Jay R.; Kling, Catherine L.; Zhao, Jinhua.

In a static setting, willingness to pay for an environmental improvement is equal to compensating variation. However, in a dynamic setting characterized by uncertainty, irreversibility, and the potential for learning, willingness to pay may also contain an option value. In this paper, we incorporate the dynamic nature of the value formulation process into a study using a contingent valuation method, designed to measure the value local residents assign to a north-central Iowa lake. Our results show that willingness to pay is highly sensitive to the potential for future learning. Respondents offered the opportunity to delay their purchasing decisions until more information became available were willing to pay significantly less for improved water quality...
