A Comparison of Auction and Choice Experiment: An Application to Consumer Willingness to Pay for Rice with Improved Storage Management AgEcon
Su, Lianfan; Adam, Brian D.; Lusk, Jayson L.; Arthur, Frank.
Experimental auction and discrete choice experiment are two popular value elicitation methods. Theoretically they should yield the same results but empirical results have been mixed (e.g., Lusk and Schroeder 2004, 2006; Corrigan et al. 2010.) This study uses both methods to determine consumers’ willingness to pay (WTP) for rice with improved insect control and for rice stored using Integrated Pest Management (IPM). This study investigates two potential reasons – anchoring and information – for why some studies have found apparent inconsistencies between auction and choice experiment results. Results indicate that consumers’ WTP derived in the auction and choice experiments are significantly different. Consumers’ average bids in the auction are higher than...

A Comparison Of Choice Experiments And Actual Grocery Store Behavior: An Empirical Application To Seafood Products AgEcon
Hudson, Darren; Gallardo, Rosa Karina; Hanson, Terrill R..
In this paper we compare results from an in-store field experiment and a mail survey choice experiment (CE) to investigate CE’s capacity in predicting grocery store market share. For the comparison, we used three seafood products: freshwater prawns, marine shrimp, and lobster. CE estimates were obtained via four econometric models: the conditional logit, the random parameter logit, the heteroskedastic extreme value, and the multinomial probit. We found that the level of control in the grocery store experiment and the choice of econometric model influenced the capacity of CE to predict grocery store market shares.

AN EMPIRICAL ASSESSMENT OF CONVERGENT VALIDITY OF BENEFIT TRANSFER IN CONTINGENT CHOICE: INTRODUCTORY APPLICATIONS WITH NEW CRITERIA AgEcon
Jiang, Yong; Swallow, Stephen K.; McGonagle, Michael P..
Benefit transfer has been an important, practical policy tool appealing to government agencies, especially when time or budget is constrained. However, the existing literature fails to support convergent validity of benefit transfer using the stated-preference method. This empirical study examines the convergent validity of benefit transfer using the choice modeling method, a potentially promising technique compatible with the heterogeneity of the transfer contexts. Based on a survey designed for Rhode Island (RI) and modified only slightly for Massachusetts (MA), regarding coastal land management, four convergent validity tests were conducted on the benefit transfer from RI to MA. Although results fail to support convergent validity in all aspects, the...

Andalusian Demand for Non-Market Goods from Mountain Olive Groves AgEcon
Arriaza Balmón, Manuel; Gomez-Limon, Jose Antonio; Kallas, Zein; Nekhay, Olexandr.
Agricultural multifunctionality is the recognition of the joint exercise of economic, environmental and social functions by this sector. In order to make this concept operative for the design of public policies, it is necessary to estimate the social demand for such functions. The main objective of this article is to present an empirical application in this line. For this purpose we have taken the agricultural system of mountain olive groves in Andalusia (Southern Spain) at risk of abandonment after the decoupling of the EU subsidies as a case study. The economic valuation technique used is the Choice Experiment. According to the results, there is a different contribution of each attribute to the improvement of the Society level of utility. The main...

Are Citizens Willing to Pay for Agricultural Multifunctionality? AgEcon
Kallas, Zein; Gomez-Limon, Jose Antonio; Arriaza Balmón, Manuel.
Agricultural multifunctionality is the recognition of the joint exercise of economic, environmental and social functions by this sector. In order to make this concept operative for the design of public policies, it is necessary to estimate the social demand for such functions. The main objective of this article is to present an empirical application in this line. For this purpose we have taken the agricultural system of cereal steppes in Tierra de Campos (Spain) as a case study. The economic valuation technique used is the Choice Experiment. The results suggest the existence of a significant demand for the different functions, although this demand is heterogeneous, depending on the socio-economic characteristics of the individuals.

Assessment of Farmer Preferences for Cattle Traits in Cattle Production Systems of Kenya AgEcon
Ouma, Emily Awuor; Abdulai, Awudu; Drucker, Adam G..
The urgent need to improve livestock productivity in sub-Saharan Africa in order to keep pace with expected increases in demand for meat and milk is very topical. Breed improvement provides key entry points for increasing productivity in cattle populations. However, there are tendencies for breed improvement programs to focus on single, market driven traits such as milk or meat production in isolation of environmental constraints and broader livestock system functions which cattle assume in developing countries. This potentially leads to genotypes that are not well adapted to the environment and not capable of performing the multiple roles that cattle assume in cattle production systems of developing countries. In developing countries, many important...

Asymmetric Search and Loss Aversion: Choice Experiment on Consumer Willingness to Search in the Gasoline Retail Market AgEcon
Castilla, Carolina; Haab, Timothy C..
Price search enables consumers to overcome information asymmetries, it can lead to a reduction in price dispersion and it can increase consumer surplus, but search is costly. In this paper, an internet survey is conducted among a random sample of 490 drivers in the State of Ohio to answer the question, when are consumers more likely to search? The internet survey affords us the opportunity to impose exogenous price changes in a random sample of gasoline consumers to examine the decision-making process behind intended search decisions. Results indicate that among the respondents who faced prices below their expected price, only 12% chose to search, whereas 45% searched when prices were above. Results suggest that asymmetric search can be explained by...

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...

Cattle farmers’ preferences for Disease Free Zones: A choice experiment analysis in Kenya AgEcon
Otieno, David Jakinda; Ruto, Eric; Hubbard, Lionel J..
Management of food-borne illnesses is important in ensuring food safety to consumers in both domestic and export markets. In livestock trade, various measures are prescribed under the Sanitary and Phytosanitary Standards (SPS) agreement of the World Trade Organization (WTO). With regard to food safety, the SPS agreement recommends establishment of Disease Free Zones (DFZs)in order to manage the spread of trans-boundary cattle diseases. DFZs have been successfully implemented in major beef exporting countries such as Australia, Botswana, Brazil and Namibia. In Kenya however, the DFZs are still in a pilot stage and it is important to understand farmers’ preferences on the type of DFZ that would be readily acceptable to them. A choice experiment survey was...

Changements organisationnels et analyse des préférences du consommateur des produits frais de la pêche par la méthode des choix multi-attributs ArchiMer
Razafimandimby, Haja.
The central purpose of this thesis is the development of fresh fishery products with on one hand the issue of organizational methods adopted by stakeholders in the fisheries sector in France and on the other hand the question of explanatory factors in consumer preferences for these products. The neo-institutional theory of governance structures is used to analyze different organizational methods adopted in the industry. The theory of innovation is mobilized to study the contribution of organizational innovations in the development of fresh products. The results of the study of governance structures reveal the complementarity between the market and hybrid forms concerning the supply of supermarkets and hypermarkets in France. Mainly observed Hybrid forms...

Comparacion de la ordenacion contingente y del experimento de eleccion en la valoracion de las funciones no privadas de los bosques AgEcon
Amoros, Joan Mogas; Riera, Pere.
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...

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.

Comparison of Stated Choice and In-store Experimental Methods in Predicting Actual Market Behavior for Freshwater Prawn (Macrobrachium rosenbergii) Consumers AgEcon
Gallardo, Rosa Karina; Hanson, Terrill R.; Hudson, Darren.
The stated choice (SC) and actual revealed pricing/purchase experimental methods were compared for their ability to predict purchasing behavior and willingness-to-pay for freshwater prawns. SC hypothetical bias may be a consequence of difficulties in controlling factors affecting real world situations, small sample sizes and confusion related to the new product.

Consumer Attitudes towards Sustainability Attributes on Food Labels AgEcon
Tait, Peter R.; Miller, Sini; Abell, Walter L.; Kaye-Blake, William; Guenther, Meike; Saunders, Caroline M..
Concerns about climate change and the general status of the environment have increased expectation that food products have sustainability credentials, and that these can be verified. There are significant and increasing pressures in key export markets for information on Greenhouse gas (GHG) intensity of products throughout its life-cycle. How this information is conveyed to consumers is a key issue. Labelling is a common method of communicating certain product attributes to consumers that may influence their choices. In a choice experiment concerning fruit purchase decisions, this study estimates willingness to pay for sustainability attributes by consumers in Japan and the UK. The role of label presentation format is investigated: text only, text and...

Consumers' choice of broiler meat in Finland: the effects of country of origin and production methods AgEcon
Pouta, Eija; Forsman-Hugg, Sari; Heikkila, Jaakko; Isoniemi, Merja; Makela, Johanna; Paananen, Jaana.
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....

Contribution of Economics to Design of Sustainable Cattle Breeding Programs in Eastern Africa: A Choice Experiment Approach AgEcon
Ouma, Emily Awuor; Abdulai, Awudu.
Although livestock forms a very important component of the livelihoods of rural populations of developing countries, productivity remains very low. Livestock keepers are beset by various constraints. In sub-Saharan Africa, cattle are exposed to a number of tropical diseases and other environmental stresses. Breed improvement programs provides key entry points for increasing productivity in cattle populations, especially those plagued by animal diseases. However, breed improvement programs have tended to focus on single, market-driven production traits in isolation of broader livestock system functions. This potentially leads to genotypes that are not well adapted to the environment and not suitable for performing the multiple roles of cattle in developing...

Differential Influence of Relative Poverty on Preferences for Ecosystem Services: Evidence from Rural Indonesia AgEcon
Glenk, Klaus; Barkmann, Jan; Schwarze, Stefan; Zeller, Manfred; Marggraf, Rainer.
Ecosystem services generate benefits that enter human consumption either directly or indirectly via their contribution to human production activities. In this contribution, we provide evidence that (i) the demand of peasants for ecosystem services in rural Indonesia depends on relative poverty; and that (ii) the type of reaction to poverty depends on the specific relation of the ecosystem services to peasant production and consumption. In early 2005 a representative choice experiment study was conducted in the Lore Lindu area in Central Sulawesi, Indonesia, to quantify regional economic preferences (marginal willingessto- pay: MWTP) for four different ecosystem services (n=249; rattan and water availability, shading in cacao agroforestry, population size...

Do Local Production, Organic Certification, Nutritional Claims, and Product Branding Pay in Consumer Food Choices? AgEcon
Batte, Marvin T.; Hu, Wuyang; Woods, Timothy A.; Stan, Ernst.
This research furthers the assessment of consumer demand for locally produced foods, while also considering a host of other food attributes that may interact to influence consumer utility. Using stated preference data from a choice-based conjoint analysis survey instrument, we estimate willingness-to-pay for processed food products (blackberry jam) that are differentiated with respect to their branding, the location of their production, certification as organically produced, branding as a product of a small family farming association, and carrying a State Proud certification. Although price is the most important single attribute influencing consumer choice for our sample, consumers also were willing to pay more for food products produced in their state or...
