Experimental Auction Procedure: Impact on Valuation of Quality Differentiated Goods

Despite increased use of experimental auctions, a myriad of different procedures are being employed without formal consideration of how the procedures might affect results. This study investigates the effect of several procedural issues on valuation estimates from experimental auctions. Results indicate the second price auction generates higher valuations than English, Becker–DeGroot–Marschak (BDM) , and random n th price auctions, especially in latter bidding rounds, and that random n th price auction yields lower valuations than English and BDM auctions. We find that endowing subjects with a good prior to eliciting bids can have an impact on valuations, but the effect varies across auction mechanism.     

Do Japanese consumers care about sustainable fisheries? Evidence from an auction of ecolabelled seafood

This paper investigates Japanese consumers' willingness to pay for Marine Stewardship Council (MSC) ecolabelled seafood using a sealed bid, second price auction. Participants in an experiment in Tokyo were provided varying degrees of information about the status of world and Japanese fisheries and the MSC program in sequential rounds of bidding on ecolabelled and nonlabelled salmon products. A random‐effects tobit regression shows that there is a statistically significant premium of about 20 per cent for MSC‐ecolabelled salmon over nonlabelled salmon when consumers are provided information on both the status of global fish stocks and the purpose of the MSC program. This premium arises from a combination of an increased willingness to pay for labelled products and a decreased willingness to pay for unlabelled products. However, in the absence of experimenter‐provided information, or when provided information about the purpose of the MSC program alone without concurrent information about the need for the MSC program, there is no statistically significant premium.     

后疫情时代游客对国家公园游憩属性的偏好与支付意愿研究——基于选择实验法的实证分析

基于武夷山国家公园在后疫情时代的调查数据,采用选择实验法和mixed logit模型,分析游客对国家公园游憩属性的偏好并计算游客的支付意愿。结果发现,在后疫情时代游客对国家公园游憩属性的偏好从高到低分别为:日消毒情况、医务室数量、日限流情况以及门票价格,且消毒水平从多日一消提升到一日一消,游客愿意为其支付68.04元,提升到一日多消,游客愿意为其支付91.31元;医务室每增加1个,游客愿意为其支付24.17元;日限流人数每减少1 000人,游客愿意为其支付16.47元。因此,增加公共区域卫生消毒次数及医务室个数,合理控制国家公园日限流人数,能提升游客对游憩地的满意程度。     

The Value of Badger Populations and Control of Tuberculosis in Cattle in England and Wales: A Note

This note reports on the results of a choice experiment survey of 400 people in England and Wales, conducted to estimate the value that society places on changes to the size of the badger population. The study was undertaken in the context of the possible need to reduce the badger population by culling to help control bovine tuberculosis in cattle. The study found that people were concerned about the problem of bovine tuberculosis in cattle, which was reflected in their willingness to pay to control the disease, and gave a relatively low value to changes in the size of the badger population (within limits). However, people did not like the idea of a policy that intentionally killed large numbers of badgers and had a relatively very high willingness to pay not to have such a policy.     

Do native and invasive labels affect consumer willingness to pay for plants? Evidence from experimental auctions

Ornamental plant sales have been identified as an important vector for the introduction of invasive plants. Increased concerns about the economic and ecological costs of invasive plants have spawned interest in identifying strategies to curtail introductions. One possible strategy is labeling plants based on whether they are invasive or native. The primary purpose of this paper was to explore how labeling plants based on invasive and native attributes might affect consumer demand. To accomplish this objective, a second price auction was used to elicit the willingness to pay (WTP) for plants with and without labels. On average, we found a $0.35 premium for plants labeled as noninvasive and native and a $1.01 to $1.66 discount for plants labeled as invasive. The size of these premiums and discounts differed in relation to various demographic, attitudinal, and preference‐related factors. Overall, our results suggest that labeling plants as invasive or native could be a viable strategy for reducing the introduction of invasive plants.     

Do consumers value hydroponics? Implications for organic certification

Recent controversy about the inclusion of hydroponics in the U.S. Department of Agriculture (USDA) organic program has highlighted uncertainty about marketing hydroponic crops. In a controversial vote in November 2017, the National Organic Standards Board chose not to recommend that hydroponic farms be banned from organic certification. It is still unclear, however, how consumers perceive and value hydroponic production. This study used a nonhypothetical choice experiment to estimate consumers’ willingness to pay for hydroponic and traditional lettuce both with and without organic certification. No hydroponic premium was found, but exposing consumers to different kinds of information about hydroponics significantly affected consumers’ preference formation. Findings generally suggest that the National Organic Program should consider ways to ensure the stability of organic premiums as perceptions about hydroponics evolve.     

Consumer’s Preference and Willingness to Pay for Apple Attributes: A Choice Experiment in Large Retail Outlets in Bologna (Italy)

ABSTRACT

We analyze the relevant quality attributes of apples which drive and influence consumer choice in the city of Bologna (Italy). A hypothetical choice experiment was conducted to elicit Italian consumer’s willingness to pay for apple attributes and was included as a part of a questionnaire survey. A group of 301 consumers were surveyed in Bologna in July and August 2016. Data were analyzed using a multinomial logit model. Results suggest Italian consumers are willing to pay more for yellow apples and for apples harvested in Trentino-Alto Adige region, compared with other Italian areas. Furthermore, results highlight a preference for locally produced apples, whereas organic apples are only slightly preferred to the not organic alternative. Results of this study could be used to develop marketing strategies for apple differentiation or for a new product development and target the right product to the right consumer.     

Consumers' Willingness to Pay for the Color of Salmon: A Choice Experiment with Real Economic Incentives

In most retail markets, sellers post the price and consumers choose which products to buy. We designed an experimental market with posted prices to investigate consumers' willingness to pay for the color of salmon. Salmon fillets varying in color and price were displayed in twenty choice scenarios. In each scenario, the participants chose which of two salmon fillets they wanted to buy. To induce real economic incentives, each participant drew one binding scenario; the participants then had to buy the salmon fillet they had chosen in their binding scenario. The choice data were analyzed with a mixed logit model.     

User fees, equity and the benefits of public outdoor recreation services

The paper addresses the question of who benefits from public recreation areas. Employing a set of survey data from users and nonusers of state-owned recreation and conservation areas in Finland, we derive two measures for distributional analysis. The first, the income elasticity of willingness to pay for recreation services, indicates that public provision of recreation benefits lower-income groups more than higher-income groups. The second, a welfare measure including efficiency loss, reveals ambiguous impacts depending on the level of the fee implemented. Low fee levels decrease recreation visits among lower-income users, whereas high fees reduce the welfare level of higher-income users in particular.
