Última Incorporating Local Water Quality in Welfare Measures of Agri-environmental Policy: A Choice Modelling Approach Employing GIS AgEcon Tait, Peter R.; Baskaran, Ramesh. The spatial distribution of agro-environmental policy benefits has important implications for the efficient allocation of management effort. The practical convenience of relying on sample mean values of individual benefits for aggregation can come at the cost of biased aggregate estimates. The main objective of this paper is to test spatial hypotheses regarding respondents’ local water quality and quantity, and their willingness-to-pay for improvements in water quality attributes. This paper combines choice experiment and spatially related water quality data via a Geographical Information System (GIS) to develop a method that evaluates the influence of respondents’ local water quality on willingness-to-pay for river and stream conservation programs in...

Ano: 2011 URL: http://purl.umn.edu/116074 EFFECTS OF ADDITIONAL QUALITY ATTRIBUTES ON CONSUMER WILLINGNESS-TO-PAY FOR FOOD LABELS AgEcon Gao, Zhifeng; Schroeder, Ted C.. Contingent valuation (CV), choice experiment (CE) and experimental auction (EA) or the combinations of the three methods are often used by researchers to elicit consumer willingness to pay for food attributes (food labels). One concern about using these approaches is that quality attributes of food provided to respondents are assumed independent of other attributes which are not provided to respondents during the survey. The limited attributes provided in a survey may lead respondents to allocate their budgets to those limited attributes rather than allocate their budgets to a larger number of product attributes to truly reveal their preferences. Surveys containing a series of online CEs were collected to investigate the effects of additional beef steak...

The purpose of this study is to examine the importance of low calorie content in Japanese consumers’ rice purchasing decisions. The Choice Modeling (Random Parameter Logit Model) is used in order to quantify the welfare change associated with the change in the level of low calorie content, local origin label, price attribute for the sample of Japanese consumers in March 2009. The consumer has a positive perception of local origin and rice cultivar label. Average evaluation of the low calorie content attribute is negative (-116 yen/5kg). But, half of samples have positive perception of low calorie content. Their willingness to pay for low-calorie content attribute range from 800-900 yen/5kg.The results suggests that latent demand for low calorie labelled...

Ano: 2012 URL: http://purl.umn.edu/124318 Assessing the economic viability of alternative water resources in water scarce regions: The roles of economic valuation, cost–benefit analysis and discounting AgEcon Birol, Ekin; Koundouri, Phoebe; Kountouris, Yiannis. This paper demonstrates a comprehensive methodology to assess the viability of an environmental management plan which has long-run economic and ecological impacts. The case study under consideration is the implementation of a water resource management plan in a water scarce region of the world, namely Cyprus. Specifically this plan proposes to replenish a depleting aquifer with treated wastewater. The methodology proposed first identifies the key stakeholder groups, namely farmers and the general public, who are hypothesized to derive economic values (benefits) from the implementation of this plan, and then implements stated preference methods to capture the total economic value of these benefits. Benefits are aggregated over the relevant populations of...

Ano: 2009 URL: http://purl.umn.edu/51692 Paying for Safety: Preferences for Mortality Risk Reductions on Alpine Roads AgEcon Rheinberger, Christoph M.. This paper presents a choice experiment, which values reductions in mortality risk on Alpine roads. These roads are on one hand threatened by common road hazards, on the other hand they are also endangered by natural hazards such as avalanches and rockfalls. Drawing on choice data from frequently exposed and barely exposed respondents, we are not only able to estimate the VSL but to explore how the respondents differ in their individual willingness-to-pay depending on personal characteristics. To address heterogeneity in preferences for risk reduction, we use a non-linear conditional logit model with interaction effects. The best estimate of the VSL in the context of fatal accidents on Alpine roads is in the range of €4.9–5.4 million with distinct...

Ano: 2009 URL: http://purl.umn.edu/54350 Economic analysis of spatial preferences heterogeneity of water quality AgEcon Martin-Ortega, Julia; Brouwer, Roy; Berbel, Julio. The main objective of this study is to account for spatial preference variability in the economic valuation of water quality improvements in the river basin context. This is expected to be particularly relevant for the implementation of the European WFD, as it will involve spatially differentiated perceptions of the benefits of water quality changes. A choice experiment is developed based on maps to elicit welfare measures for water quality improvements across sub-basins in the Guadalquivir River Basin in Spain. Variation is introduced simultaneously in the spatial distribution of goods and services and their beneficiaries, for the accounting of spatial preference heterogeneity (i.e. people’s different valuation of changes in environmental good provision...

Ano: 2009 URL: http://purl.umn.edu/50626 Consumer Responses to New Food Quality Information: Are Some Consumers More Sensitive than Others AgEcon Gao, Zhifeng; Schroeder, Ted C.. In the main approaches used to elicit consumer preference for food attributes, only limited attribute information are present. Though useful for ranking and revealing consumer preferences, these methods are not appropriate when results may be dependent upon the information set presented in the surveys. Studies have found out that additional quality information in surveys significantly affected respondents’ attitudes to or WTP for a specific product attributes. By using cluster analysis we are able to classify respondents into different consumer groups and investigate the difference in responses to new attribute information across consumer groups. Results show that different types of consumer’s WTP for beef steak attributes varies significantly and their...

Ano: 2008 URL: http://purl.umn.edu/6168 Functional Ingredients and Food Choice: Results from a Choice Experiment AgEcon Fraser, Iain; Bitzios, Michael; Haddock-Fraser, Janet. In this paper we present the results of a Choice Experiment (CE) conducted to examine how the inclusion of an attribute for a functional ingredient affects consumer food choice. Specifically, we examine consumer attitudes towards bread and the inclusion of a functional ingredient (eg, inulin), which can be added to bread to increase the quantity and the effectiveness of fibre in the final product A novel feature of the design of this CE was the use of Means-End-Chain analysis via semi-structured interviews to reveal key attributes to be included in the CE. In addition, the CE included the Dutch Eating Behaviour Questionnaire (DEBQ) so as to collect information on all participants underlying eating behaviours. Preliminary analysis of the data reveals that...

Ano: 2010 URL: http://purl.umn.edu/91755 Identifying Market Preferences for High Selenium Beef AgEcon Hovde, Scott C.; Wachenheim, Cheryl J.; Hearne, Robert R.; Nganje, William E.. Selenium is an element found in relatively high concentrations in crops and livestock raised on high-selenium soils located in North and South Dakota. Evidence suggests that a high-selenium diet such as would be obtained from consuming these products can reduce the risk of certain cancers. The region's livestock and grain producers are exploring potential high-selenium product marketing opportunities. A choice experiment was conducted to identify preferred attributes for a high-selenium beef product and the characteristics of potential market segments. In a national survey, participants chose between different levels of health claim approval and research, prices, and selenium origin. A multinomial logit regression model was estimated. Labeling...

Ano: 2007 URL: http://purl.umn.edu/7633 Targeting Consumers by Store - The Basis of Increased Sales with Less Advertising AgEcon Ubilava, David; Foster, Kenneth A.. Conditional Logit approach was used to analyze the Choice Experiment data obtained from the grocery stores and supermarket of Tbilisi, Georgia. Results show that customers' preferences for selected pork attributes in different stores are not the same. So, targeting customers by store can be beneficial marketing tool for pork suppliers.

Ano: 2007 URL: http://purl.umn.edu/34909 Is Embedding Entailed in Consumer Valuation of Food Safety Characteristics? AgEcon Morkbak, Morten Raun; Christensen, Tove; Gyrd-Hansen, Dorte E.; Olsen, Soren Boye. Consumers’ preferences for food safety characteristics are investigated with particular focus on existence of an embedding effect. Embedding exists if consumer valuation of food safety is insensitive to scope. Two choice experiments have been conducted valuing food safety in respectively minced pork and chicken breasts, exemplified by avoiding human risks of Salmonella infections and strengthening the restrictions of using antibiotics in the pork production and in terms of avoiding human risks of Salmonella and Campylobacter infections respectively. The results showed no indications of an embedding effect between the food safety characteristics, in neither of the cases.

Ano: 2009 URL: http://purl.umn.edu/58099 Households’ WTP for the Reliability of Gas Supply AgEcon Chou, Wan-Jung; Bigano, Andrea; Hunt, Alistair; La Branche, Stephane; Markandya, Anil; Pierfederici, Roberta. The security of natural gas supply is an important issue for all EU countries due to the region’s heavy dependence on imported supply sources and in light of energy demand for gas that is continuously increasing. Discussions have emphasised strategies for securing the supply at the macro level, e.g. diversification in supply sources, increase in storage capacity, etc. By contrast, consumers’ demand for the reliability of gas supply is rarely investigated. Hence this study was conducted to examine the economic implications associated with the security of gas supply directly to domestic consumers. Based on the choice experiment approach, household surveys were conducted in France, Italy and the UK. The results confirmed that the degree of the economic impact...

Ano: 2011 URL: http://purl.umn.edu/115740 Discrete Choice Modeling of Consumer Preferences for Sustainably Produced Steak and Apples AgEcon Sackett, Hillary M.; Shupp, Robert S.; Tonsor, Glynn T.. "Sustainably produced" food labels have rapidly grown in popularity over the past decade (Batte 2011). Moreover, because there is no government agency overseeing certification of these production methods, consumers are generally confused about the production attributes that may or may not be present in a sustainable food system. This paper analyzes data from a hypothetical choice experiment to better understand consumer purchasing behavior when faced with competing food production attributes such as "organic" and "local". We seek to estimate preferences for "sustainably produced" food products and determine how they may be affected by varying degrees of information about sustainable agricultural systems. Additionally, the willingness to pay measurements...
