Analysis of Cardinal and Ordinal Assumptions in Conjoint Analysis AgEcon
Harrison, R. Wes; Gillespie, Jeffrey M.; Fields, Deacue.
Of twenty-three agricultural economics conjoint analyses conducted between 1990 and 2001, seventeen used interval-rating scales, with estimation procedures varying widely. This study tests cardinality assumptions in conjoint analysis when interval-rating scales are used, and tests whether the ordered probit or two-limit tobit model is the most valid. Results indicate that cardinality assumptions are invalid, but estimates of the underlying utility scale for the two models do not differ. Thus, while the ordered probit model is theoretically more appealing, the two-limit tobit model may be more useful in practice, especially in cases with limited degrees of freedom, such as with individual-level conjoint models.

An Application of Conjoint Analysis in Agricultural Sustainability Assessment AgEcon
Sydorovych, Olha; Wossink, Ada.
Increasing public interest in the concept of sustainable agriculture has resulted in the development of a number of methods that could be used for the assessment of sustainability of various agricultural production systems. Because of its complex, multi-dimensional nature, sustainability is most often assessed using numerous indicators, which make aggregate comparisons among systems difficult. In this paper we propose a methodology that could be beneficial in aggregate sustainability assessment. We apply conjoint analysis to identify economic, social, and ecological attributes that are perceived as important for agricultural sustainability by different stakeholders and to assess their relative impact on the overall sustainability measure.

PUBLIC SUPPORT FOR LAND PRESERVATION: MEASURING RELATIVE PREFERENCES IN DELAWARE AgEcon
Duke, Joshua M.; Ilvento, Thomas W.; Hyde, Rhonda A..
Public preferences for nonmarket services of preserved land in Delaware are measured using two survey techniques. The results of a conjoint experiment, using a sample of 199 Delawareans, suggest that the environmental and agricultural attributes of preserved land are most important to the residents. The conjoint results also suggest that these services are of substantial value to Delawareans; at the margin, at least, agricultural and environmental preserved land provide net benefits to the public. The analytic hierarchy process is used to assess separate survey results from 129 Delawareans. The results provide specific weights on the relative importance of attributes and qualities of preserved land, which in large part replicate and reinforce the results...

Assessing Food Safety Concepts on the Dairy Farm: The Case of Chemical Hazards AgEcon
Valeeva, Natasha I.; Meuwissen, Miranda P.M.; Oude Lansink, Alfons G.J.M.; Bergevoet, Ron H.M.; Huirne, Ruud B.M..
Adaptive conjoint analysis was used to elicit farmers' and experts' preferences for attributes of improving food safety with respect to chemical hazards on the dairy farm. Groups of respondents were determined by cluster analysis based on similar farmers' and experts' perceptions of food safety improvement. Results show differences in priority of the more important attributes. However, respondents in all groups valued "identification of treated cows" as one of the most important attributes. The results provide the processing industry and extension service with a better understanding of aspects that may form farmers' perceptions of improving food safety, and thus help to define the message for targeting different farmer groups.

Applying Geographically Weighted Regression to Conjoint Analysis: Empirical Findings from Urban Park Amenities AgEcon
Tanaka, Katsuya; Yoshida, Kentaro; Kawase, Yasushi.
The objective of this study is to develop spatially-explicit choice model and investigate its validity and applicability in CA studies. This objective is achieved by applying locally-regressed geographically weighted regression (GWR) and GIS to survey data on hypothetical dogrun facilities (off-leash dog area) in urban recreational parks in Tokyo, Japan. Our results show that spatially-explicit conditional logit model developed in this study outperforms traditional model in terms of data fit and prediction accuracy. Our results also show that marginal willingness-to-pay for various attributes of dogrun facilities has significant spatial variation. Analytical procedure developed in this study can reveal spatially-varying individual preferences on attributes...

Consumer Preferences and Trade-Offs for Locally Grown and Genetically Modified Apples: A Conjoint Analysis Approach AgEcon
Novotorova, Nadezhda K.; Mazzocco, Michael A..
Using conjoint analysis methodology, this study used an online survey to measure consumers’ preferences for the apple attributes as place of production, method of production, and price. The results of the conjoint analysis indicate that consumers are willing to make trade offs between the studied attributes. Segment analysis indicates Place-oriented consumers may be willing to pay 60% to 70% premiums for locally grown apples. The high consumer preferences for locally grown products combined with environmental benefits transferred through genetic modification provide an opportunity for producers to capture and build their markets, especially within certain market segments.

PRIVATE PARTICIPATION IN AGRICULTURAL EXTENSION IN NIGERIA AND BENIN: DETERMINING THE WILLINGNESS TO PAY FOR INFORMATION AgEcon
Horna, J. Daniela; Smale, Melinda; von Oppen, Matthias.
A typical private good is defined by its excludability and rivalry characteristics. Information might not generate rivalry among its users. By contrast, excludability is certainly a characteristic of information and its delivery can generate incentives for private participation. This study examines farmers'’ preferences for seed of new rice varieties and their willingness to pay for related information in villages of Nigeria and Benin. Conjoint analysis is used to estimate the structure of farmers'’ preferences for rice seed given a set of alternatives. Farmers are considered to be maximizers of utility rather than profit, preferring one variety over another based on the utility they obtain from its attributes, which depends on their own social and...

Ansätze für ein produktspezifisches Marketing für Öko-Produkte im konventionellen Handel - Eine Verbraucheranalyse im Elbetal AgEcon
Wirthgen, Antje.
Against the background of increasing political importance of organic farming combined with market potential for organic food, especially concerning conventional retailers, this article aims to improve organic marketing for retailers by means of product-specific analysis of consumers’ purchase behaviour. The main research aspects based on a consumer survey are preference testing and attitude measuring to explain consumers’ purchase behaviour concerning selected products. The preference test furthermore offered the possibility to examine the impact of substitutes produced by other environmentally friendly production methods and to estimate the market potential for organic food. The findings of this research are firstly hints on market potential for organic...

RANGE AND NUMBER-OF-LEVELS EFFECTS IN DERIVED AND STATED MEASURES OF ATTRIBUTE IMPORTANCE AgEcon
Verlegh, Peeter W.J.; Schifferstein, Hendrik N.J.; Wittink, Dick R..
We study how the range of variation and the number of attribute levels affect five measures of attribute importance: full profile conjoint estimates, ranges in attribute level attractiveness ratings, regression coefficients, graded paired comparisons, and self-reported ratings. We find that all importance measures are affected by the range manipulation. The number of attribute levels affects only two measures. The results allow us to benchmark the magnitude of the number-of-levels effect against the range effect: conjoint importance estimates were approximately equally affected by a threefold increase in the range of attribute variation and by the insertion of two intermediate attribute levels. Our findings show that the number-of-levels effect is most...

A CONJOINT ANALYSIS OF NEW FOOD PRODUCTS PROCESSED FROM UNDERUTILIZED SMALL CRAWFISH AgEcon
Harrison, R. Wes; Ozayan, Aylin; Meyers, Samuel P..
Attributes for two value-added seafood products derived from underutilized crawfish are analyzed using conjoint data from seafood restaurants in the southern region of the United States. Preferences for the products' form, price, and flavor attributes were tested. Statistical tests revealed that the attribute interactions were not significant, and part-worth utilities for all main effects were estimated using an additive preference model. Results indicate that the new crawfish products should be marketed as a high-quality fresh soup base or seafood stuffing, priced between 30% and 50% of the cost of fresh crawfish tail meat.

Estudio de las preferencias de consumidores y distribuidores especializados respecto del producto ecologico AgEcon
Sanchez Garcia, Mercedes; Sanjuan, Ana Isabel; Gil Roig, Jose Maria; Gracia, Azucena; Soler, Francisco.
RESUMEN: La creciente preocupación por la seguridad alimentaria y la mayor sensibilidad al deterioro medioambiental pueden favorecer la expansión de los productos ecológicos. No obstante, el consumo de este tipo de productos no ha crecido al mismo ritmo que la producción. El diferencial de precios respecto de los productos convencionales, los deficientes canales de distribución, y su desconocimiento parecen estar en la raíz del problema. El objetivo de este trabajo se centra en estudiar en profundidad estas limitaciones. Con este fin, se han realizado dos entrevistas, en Pamplona, a los miembros de la cadena agroalimentaria básicos para el posible desarrollo de dicho mercado: consumidores y distribuidores. El primer colectivo se ha segmentado en función de...

Farmer Willingness to Pay for Seed-Related Information: Rice Varieties in Nigeria and Benin AgEcon
Horna, J. Daniela; Smale, Melinda; von Oppen, Matthias.
A typical private good is defined by its excludability and rivalry characteristics. Information embodied in a technology might not generate rivalry among its users. By contrast, excludability is certainly a characteristic of this kind of information and its delivery can generate incentives for private participation. This study examines farmers’ preferences for seed of new rice varieties and their willingness to pay for seed-related information in villages of Nigeria and Benin. Conjoint analysis is used to estimate the structure of farmers’ preferences for rice seed given a set of alternatives. Farmers are considered to be consumers of seed as a production input, preferring one variety over another based on the utility they obtain from its attributes, which...

Consumer Preferences for Quality Foods from a South European Perspective: A Conjoint Analysis Implementation on Greek Olive Oil AgEcon
Krystallis, Athanasios; Ness, Mitchell.
The objective of the present study is to describe the preferences of younger, more educated and higher income Greek consumers for "quality" olive oil brands - quality being defined as a bundle of extrinsic quality cues such as quality assurance labels, health-related information, country-of-origin indication, bottling material and price. The aim of the research is, with the implementation of a conjoint analysis task, to describe and analyze consumer preferences using a random, stratified, sample of urban consumers. The extrinsic quality attributes of olive oil, strongly linked to a previous qualitative, Means-end Chains (MEC) analysis survey, is used as starting points for the development of conjoint profiles. Special emphasis is given to the development...

Evaluation of the effects of changes in regulatory policies on consumers perception: the case of designations of origin in the wine common market organisation AgEcon
Chiodo, Emilio; Casolani, Nicola; Fantini, Andrea.
The paper analyses how different aspects connected with regulations can influence the consumers’ quality perception and the value that consumers attribute to the wine sector products. In particular, aspects concerning labelling and presentation of designations of origin, which, in turn, mirror different regulations of production methods, are considered. Consumers’ preference can allow enterprises to complying with more restrictive rules and sustain higher costs for differentiate their products and achieve higher quality. When choosing a product, consumers do not evaluate each single quality factor but the product as a whole, therefore the analysis has to be done with a methodology considering both the combination of all characteristics of the product, and...

Effects of Seed and Farm Characteristics on Cottonseed Choice: A Choice-Based Conjoint Experiment in the Mississippi Delta AgEcon
Banerjee, Swagata (Ban); Hudson, Darren; Martin, Steven W..
Producers’ preferences for cottonseed with respect to price, seed type, yield, and fiber quality are examined by a willingness-to-pay approach via mail surveys. Results indicate a positive willingness to pay (WTP) for technology relative to conventional cottonseed, and WTP increases with the level of technology. Yield and quality also show a positive WTP. Larger farms have a higher WTP for technology, and farms with more farm labor have a lower WTP for technology. These results suggest economies of size in technology adoption (biotechnology is not size-neutral) and that labor and biotechnology are direct substitutes.

Consumer Likelihood to Purchase Chickens with Novel Production Attributes AgEcon
Bernard, John C.; Pesek, John D., Jr.; Pan, Xiqian.
Typical supermarket chickens are produced with novel or controversial attributes. This continues despite contrasting growth in consumer interest in organic and natural foods. This study surveyed Delaware consumers’ likelihood to purchase chicken given different attributes: free range, given antibiotics, irradiated, fed genetically modified (GM) fee, GM chicken, and price. Examining conjoint analysis data with a heteroskedastic two-limit tobit model, GM chicken and other novel attributes were found to lower purchase likelihood significantly. Understanding these results should help the industry meet consumer preferences while aiding its continued expansion to benefit workers and growers across the South.
