Fitting Model

<p>In the choice experiment method respondents are typically assumed to hold a perfectly rational selection rule. However, individuals may use other selection rules when choosing the preferred alternative to simplify the choice. In this paper, we make use of the “cutoffs” model to as a way of handling the non-compensatory nature of choices. Furthermore, we extend it to allow consideration of inconsistencies in choice in stated preference choice data. We find that this allows a better fitting model to be estimated, and that it produces considerable effects on the implied willingness to pay.</p>

Abstract In order to integrate ecosystem services (ES) in designing agri-environmental policy, we investigated both the demand for, and supply of, ES from agricultural environments in Finland. Using the discrete choice experiment method, we measured citizens’ willingness to pay (WTP) for four different ES and analysed farmers’ compensation request (willingness to accept [WTA]) for producing these services. Biodiversity and water quality gathered the highest WTA of farmers, but also the highest WTP of citizens. Overall, the average WTA exceeded the WTP for almost all attributes and levels, but 20–27 per cent of farmers were willing to produce the ES with the compensation lower than citizens’ WTP.

Purpose – The purpose of this paper is to explore farmer acceptance of a biofortified staple food crop in a developing country prior to its commercialization. The paper focuses on the hypothetical introduction of a high-iron pearl millet variety in Maharashtra, India, where pearl millet is among the most important staple crops. Design/methodology/approach – A choice experiment is used to investigate farmer preferences for and trade-offs among various production and consumption attributes of pearl millet. The key pearl millet attributes studied include days it takes pearl millet to mature, color of the roti (flat bread) the grain produces, the presence of high-iron content (nutritional attribute), and the price of the pearl millet seed. Choice data come from 630 pearl millet-producing households from three purposefully selected districts of Maharashtra. A latent class model is used to investigate the heterogeneity in farmers’ preferences for pearl millet attributes and to profile farmers who are more or less likely to choose high-iron varieties of pearl millet. Findings – The results reveal that there are three distinct segments in the sample, and there is significant heterogeneity in farmer preferences across these segments. High-iron pearl millet is valued the most by larger households that produce mainly for household consumption and currently have lower quality diets. Households that mainly produce for market sales, on the other hand, derive lower benefits from consumption characteristics such as color and nutrition. Research limitations/implications – The main limitation of the study is that it uses a stated preference choice experiment method, which suffers from hypothetical bias. At the time of implementing this study biofortified high-iron pearl millet varieties were not yet developed, therefore the authors could not have implemented revealed preference elicitation methods with real products and payment. Originality/value – The method used (stated preference choice experiment method) is commonly used to value non-market goods such as environmental goods and products that are not yet in the market. It’s application to agriculture and in developing countries is increasing. As far as the authors know this is the first choice experiment implemented to investigate farmer/consumer preferences for biofortified crops. The study presents valuable information for development and delivery of biofortified crops for reducing micronutrient deficiencies.

Experiment Method

This study investigates the effects of eco-information on the environmental consciousness and attitudes of consumers towards agricultural products. We focus on Japanese rice to provide recommendations to protect the Ibis, an endangered bird in Japan, and evaluate how Ecologically Conscious Consumer Behavior (ECCB) affect consumers’ Willingness To Pay (WTP) via the choice experiment method. Participants are provided with the necessary eco-information pertaining to rice production, and are required to taste and purchase the rice. The results indicate that consumers with high ECCB display higher WTP after they are provided with the necessary eco-information pertaining to rice production.

Payment for Forest Environmental Services is one of Vietnam’s most successful policies in socializing forest protection in particular and environmental protection in general. However, the application of this policy in the field of tourism is limited. This study employed Choice Experiment Method to estimate the willingness to pay of tourists, with the aim of providing scientific basis for the application of this policy in Ba Vi National Park. The results showed that 74% of tourists agreed with an increase in entrance fee and in room rate to contribute to the implementation of the policy in the national park. In detail, tourists’ willingness to pay for the increase in the entrance fee is roughly VND 37,000 (equivalent to 61% of the current price) and for the increase in the room rate is roughly VND 181,000 (equivalent to 24% of the average rate).

Reducing Potential

Cheap Talk (CT) is a mainstay technique among stated preference practitioners to reduce Hypothetical Bias (HB). The usefulness of CT may be questionable in online surveys due to the limited control researchers have on participant engagement. In the context of an online choice experiment on hotels, we compare a control group of respondents who receives a CT script as a traditional passage of text versus a group who must answer an attention-check question to verify their comprehension of the script as well as another group who receives the CT script as a video and then answer the attention-check question. We find that compared to the control group, simply offering the attention-check question reduced willingness to pay (WTP), and those who answer the attention-check question correctly behaved differently to those who did not. Overall, video CT script is shown to improve attention and be more effective in reducing potential HB than a text-based script.

Clean Drinking Water

Clean drinking water can be secured either through protection of the groundwater resource or via purification of polluted water. In this study, the choice experiment method is used to assess the benefits of groundwater protection compared with the benefits of purification. The choice experiment method has been chosen as it allows the effects on drinking water and those on surface water quality to be assessed separately. The benefits associated with clean drinking water are found to be significant for both management options, although the willingness to pay for protection exceeds the willingness to pay for purification.

Production Characteristics

We used Likert-scale questions and the choice experiment method to evaluate the general perception of consumers regarding differentiated products and to estimate their willingness to pay for characteristics of a differentiated coffee, respectively (N=172). The three characteristics perceived as most important are that the product does not use child labor, that more detailed product information is provided in the packaging and that it is produced locally. In addition, we found that consumers are willing to pay between $1,37 and $4,38, in addition to the current price, for an 8-ounce package of coffee with different production characteristics.
