Última Comparing Willingness to Pay for Organic, Natural, Locally Grown, and State Marketing Program Promoted Foods in the Mid-Atlantic Region AgEcon Onken, Kathryn A.; Bernard, John C.; Pesek, John D., Jr.. A choice experiment of Mid-Atlantic consumers was conducted to determine marginal willingness to pay for the attributes organic, natural, locally grown, and state marketing program promoted for strawberry preserves. The influence of purchasing venue on willingness to pay was also examined. Results indicated a price premium when purchased at a farmers market across all five states and versions. Organic was preferred to natural in only one state. Preference ordering between local and state program promoted varied. Consumers in Maryland and Pennsylvania clearly preferred local, while those in New Jersey seemed most likely to prefer the state program version.

Among consumers there is an increasing interest and concern about the ways food is produced. This calls for the poultry industry to differentiate their products and production methods to directions valued by the consumers. In this study we use choice experiment to analyse the importance of broiler production method and the country of origin for the Finnish consumers. In the experiment, we offer several alternatives for regular broiler, including products that have been produced using organic methods, as well as products produced by emphasising animal welfare or consumer health aspects. The conditional logit model of consumer preferences for broiler meat in Finland revealed the very strong positive perceptions of domestically produced broiler products....

There is an emerging body of literature analyzing how smallholder farmers in developing countries can be linked to modern supply chains. However, most of the available studies concentrate on farm and farmer characteristics, failing to capture details of institutional arrangements between farmers and traders. Moreover, farmers’ preferences have rarely been considered. Here, we address these gaps by analyzing different market channels for sweet pepper in Thailand. Using data from a survey and choice experiment with farmers, we find that there is a general preference for marketing options that do not involve a contract. Additional provision of inputs and credit can increase the attractiveness of contracts. Yet, the most important factor for farmers is to...

Ano: 2011 URL: http://purl.umn.edu/108349 Efficiency benefits of choice model experimental design updating: a case study AgEcon Kerr, Geoffrey N.; Sharp, Basil M.H.. Efficient experimental designs offer the potential to reduce confidence intervals for parameters of interest in choice models, or to reduce required sample sizes. C-efficiency recognises the salience of willingness to pay estimates rather than utility function parameters. This study reports on a choice model application that incorporated updated statistical designs based on initial responses in order to maximise C-efficiency. The revised design delivered significant improvements.

Ano: 2009 URL: http://purl.umn.edu/47623 MODELING FARMERS PREFENCES FOR AGRIENVIRONMENTAL SCHEME DESIGN: A SPANISH CASE STUDY AgEcon Espinosa-Goded, Maria; Barreiro-Hurlé, Jesús; Ruto, Eric. Agri-environmental schemes (AES) have had a limited effect on European agriculture due to farmer’s reluctance to participate in them. Information on the role that AES design can have on encouraging farmers to participate can be an important input into the design of such policies. This paper investigates farmers’ preferences for different design options related to a specific AES in Spain using a mixed logit error component choice experiment approach allowing for preference heterogeneity and correlation amongst the non status quo alternatives. In particular, findings show farmers preference for greater flexibility in scheme implementation, presence of a fixed-rate payment per contract and additional advisory services. However, heterogeneity in the value of...

Ano: 2009 URL: http://purl.umn.edu/50328 Ethnic food preferences in the Spanish market AgEcon Camarena-Gomez, Dena M.; Sanjuan, Ana Isabel. A labelled choice experiment is conducted in order to investigate preferences of Spanish consumers towards ethnic cuisines. In particular, the three best known cuisines, Mexican, Arab and Asian, are considered, across three consumption situations: restaurant, take-away and at home. Wald statistics are applied in order to assess the differential marginal utilities of ethnic food in alternative consumption situations, and the appropriateness of considering a linear effect in price.

Ano: 2008 URL: http://purl.umn.edu/44421 Product Differentiation and Market Segmentation in Applesauce: Using a Choice Experiment to Assess the Value of Organic, Local, and Nutrition Attributes AgEcon James, Jennifer S.; Rickard, Bradley J.; Rossman, William J.. Recently, there has been much interest among horticultural producers concerning the marketing of organic and locally produced food. A consumer survey was administered that asked respondents to choose an applesauce product from a list of products differentiated by price, and by labels that described fat content, nutrition content, and whether the product was grown organically and/or locally. Our analysis indicates that consumers were willing to pay more for locally grown applesauce compared to applesauce that was labeled USDA Organic, Low Fat, or No Sugar Added. Furthermore, we find evidence that increased knowledge of agriculture decreases the willingness to pay for organic and locally grown applesauce.

Stated consumer preferences for walnuts in Spain are investigated by means of a choice experiment. Conditional heterogeneity is explored, assuming two possible sources: how often walnuts are consumed and how driven by health and nutrition attitudes or convenience the consumer is. In particular, the possibilities for a mostly unknown variety in the Spanish market are investigated. Specific guidelines for the distribution and commercialisation of walnuts are provided.

Water quality and quantity concerns in Canterbury are intrinsically related to agriculture. Monetary values for impacts on streams and rivers is lacking in policy debate. This paper employs choice modelling to estimate values of three impacts on rivers and streams in Canterbury associated with agriculture: health risks of E coli from animal waste, ecological effects of excess nutrients, and low-flow impacts of irrigation. This study provides a valuation of outcomes for public policy implemented in Canterbury such as The Dairy and Clean Streams Accord, Living Streams, and The Restorative Programme for Lowland Streams.

Ano: 2008 URL: http://purl.umn.edu/96445 Product Differentiation and Market Segmentation in Applesauce: Using a Choice Experiment to Assess the Value of Organic, Local and Nutrition Attributes AgEcon James, Jennifer S.; Rickard, Bradley J.; Rossman, William J.. Recently there is much interest among horticultural producers concerning the marketing of organically- and locally- produced food. Here we developed a consumer survey that asked respondents to choose an applesauce product from a list of products differentiated by price and four attributes. The products were differentiated by labels that described fat content, nutrition content, and whether the product was grown organically and/or locally. The survey was distributed to 3,000 residents in rural Pennsylvania and over 1,500 responses were collected yielding a response rate of 56%. Survey results were used to assess consumers’ willingness to pay for the product attributes in applesauce, and we found that consumers were willing to pay more for locally-grown...

RESUMEN: En este trabajo se presenta una comparación entre dos métodos de valoración de preferencias declaradas: la ordenación contingente y el experimento de elección. Se incluye una aplicación empírica en la que se valoran los impactos que una determinada forestación de terrenos agrícolas en Cataluña tendría sobre la función recreativa, de absorción de CO2 y de protección frente a la erosión de los bosques. Los resultados muestran diferencias entre los valores obtenidos a partir de los dos métodos, siendo los del método de elección significativamente mayores. Además, esta divergencia se mantiene cuando se comparan observaciones pairwise obtenidas directamente a través del método de elección con las simulaciones pairwise procedentes de la ordenación...

Holly; Wu, Laping; Bai, Junfei; Olynk, Nicole J.. Food safety issues often arise from problems of asymmetric information between consumers and suppliers of food with regards to product-specific attributes or characteristics. Food safety concerns in China are having a drastic impact on consumer behavior, commodity markets, international trade and food security. An additional challenge to the problem of asymmetric information lies in the inherent structure of the governing bodies which oversee food safety and quality. Unlike the United States and other developed countries, China’s food safety is regulated by several government entities with different and sometimes overlapping responsibilities. As a result consumers don’t have a comprehensive food safety and quality system on which to base their economic...

Ano: 2011 URL: http://purl.umn.edu/98723 European Preferences for Beef Steak Attributes AgEcon Tonsor, Glynn T.; Schroeder, Ted C.; Fox, John A.; Biere, Arlo W.. A choice experiment is used to evaluate how consumers in London, Frankfurt, and Paris value beef steaks with attributes such as: "hormone-free," "GM-free," farm-specific source verification, and domestic origin. The effect of various consumer characteristics on steak selection is also evaluated. Results suggest that European consumers are significantly heterogeneous in their preferences for beef steak attributes. French and German consumers have a higher willingness to pay to avoid genetically modified feed use than British consumers, while German and British consumers would pay more for growth hormone-free beef. French and German consumers are willing to pay for farm-specific source verification.

Ano: 2005 URL: http://purl.umn.edu/31213 Japanese Consumers’ Valuation of U.S. Beef and Pork Products after the Beef Trade Ban AgEcon Peterson, Hikaru Hanawa; Burbidge, Linda D.. Analysis of survey data indicates that Japanese consumers discount their willingness to pay for U.S. beef and pork relative to that of domestic products, but that the discounts have declined from 2006 to 2009. The discounts for U.S. products were greater than those imported from other countries in 2006, but the 2009 discounts were statistically indistinguishable across origins. Our findings also suggest than Japan is a receptive market for meat produced with GM-free feed and for meat products meeting full organic standards.

Ano: 2012 URL: http://purl.umn.edu/122305 None-of-These Bias in Stated Choice Experiments AgEcon Alfnes, Frode; Steine, Gro. We conduct a within-sample test of hypothetical bias and parameter equality between a hypothetical stated choice (SC) experiment using pictures and a real choice (RC) experiments using products. With exception of the none-of-these alternative-specific dummy, we cannot reject parameter equality between the two datasets. However, when we estimate the models separately with no parameter restrictions, the SC experiment gave WTP estimates that were approximately 50 percent higher and marginal WTP estimates that were almost two times as high as the corresponding estimates from the RC experiment. However, even though the monetary value of the WTP disparity was large, the disparity between the WTP estimates from the two data sets was not statistically significant.

Ano: 2009 URL: http://purl.umn.edu/97156 Benefit Transfer: Choice Experiment Results AgEcon Kerr, Geoffrey N.; Sharp, Basil M.H.. Benefit transfer entails using estimates of non-market values derived at one site as approximations to benefits at other sites. The method finds favour because it can be applied quickly and cheaply, however the validity of benefit transfer is frequently questioned. Published studies generally indicate that errors from the approach can be extremely large and could result in significant resource misallocations. Assessing the validity of benefit transfer is complicated by differences in the nature of study and policy sites, the changes being valued, valuation methods, time of study, availability of substitutes and complements, and demographic, social and cultural differences. A choice experiment was used to evaluate the transferability of benefit estimates...
